Good morning Year Six, I hope you are all well and your lights are shining bright! Last week we looked at key vocabulary and went on a light hunt.
Today you will conduct an experiment at home (or school) using items you all have access to. The purpose of our experiment is to see in what direction light travels (hence the title straight or wavy?)
Aim:
To discover how light travels and learn about the physics behind light.
Prediction (Hypothesis):
I predict light travels in……. direction.
Materials:
*3 pieces of paper/card
*Blu-tac/clay/play dough/tape
*Torch/ mobile torch
*Ruler/Scissors
Method:
1. For each piece of card, use a ruler to draw lines connecting opposite corners of the card (creating a large X)
2. At the intersection of the two lines, cut a hole in the center of the cards.
3. For each card, use a small piece of blu-tac/ and place the card into the clay to create a “stand” for the card. Place the cards so that they stand vertically and at an equal distance from each other. See Diagram.
5. Place the flashlight at one end of the row of index cards and turn off the light in the room.
6. Arrange the cards so that light can be seen through all the holes.
7. Observe and record your observations.
Conclusion:
1. How can light be seen through all the cards?
2. What would happen if the cards were not aligned?
3. What does the experiment prove about the path light travels?
4. What would happen if the holes were smaller?
Please write your plan out and ensure the conclusion questions are answered. Feel free to send photos of yourself conducting the experiment etc.
Prediction (Hypothesis):
My hypothesis is that light travels in a straight light and not a wavy one.
Conclusion:
1. How can light be seen through all the cards?
Light can be seen through all the cards because light travels in a straight line. As there is a hole in each of the cards, the light will shine through the hole in the cards.
2. What would happen if the cards were not aligned?
The light will not shine as brightly. As white paper was used, the light would be able to shine through it vaguely. However this would not be very efficient.
3. What does the experiment prove about the path light travels?
The experiment proves that light travels in a straight line.
4. What would happen if the holes were smaller?
If the holes were smaller, the amount of light that would shine through would be less.
Prediction (hypothesis):
I predict that the light travels in a straight line.
Conclusion: How can light be seen through all the cards?:
Well, there is a hole in each of the cards, and if the light is straight it shines through.
What would happen if the cards were not aligned?:
Because the paper was white, the light would shine through vaguely, but not as bright.
What does the experiment prove about the path the light travels?:
The experiment proves that light travels in a straight line.👍
What would happen if the holes were smaller?:
If the holes in the cards were smaller the light would shine through less.
Have you carried out the experiment? What would your prediction be it you used a mirror ?
I have sent you my work.
Got it thanks Zuzanna 👍
Prediction (Hypothesis):
My hypothesis is that light travels in a straight light and not a wavy one.
Conclusion:
1. How can light be seen through all the cards?
Light can be seen through all the cards as light travels in a straight line. A s there is a hole in each of the cards, the light will shine through the hole in the cards.
2. What would happen if the cards were not aligned?
The light will not shine as brightly. As white paper was used, the light would be able to shine through it vaguely. However this would not be very efficient.
3. What does the experiment prove about the path light travels?
The experiment proves that light travels in a straight line.
4. What would happen if the holes were smaller?
If the holes were smaller, the amount of light that would shine through would be less.
When does light not travel in a straight line?
Prediction (Hypothesis):
I predict light travels in a straight direction.
Conclusion:
1.) How can light be seen through all the cards?
Because light is a straight line so it can be seen through all the cards.
2.) What would happen if the cards were not aligned?
The light would not go through all the cards.
3.) What does the experiment prove about the path light travels?
Light travels in a straight line.
4.) What would happen if the holes were smaller?
The light won’t go through the holes if they were smaller.
What would happen if the holes were larger?
The light would go through and there will be more light.
Prediction:
I predict that the light will travel in a straight line and through all the card and glass. I believe this because the light will be aiming at the glass and it will travel through in a straight line depending on how the glass is placed.
Conclusion:
1. How can light be seen through all the cards?
The light will be shown if nothing is blocking it because light travels in a straight line so it will be shown on all cards and if it is not you can move the cards around in a direction where it hits all the card and is shown.
2. What would happen if the cards were not aligned?
If the cards were not aligned then the light will travel only on the direction the card is facing and of there is now card going on a straight line the light will end and just keep hitting the card.
3. What does the experiment prove about the path light travels?
This experiment proves that light will travel in a straight line depending on how the card is facing. It has also shown that light can go through small holes and still portray rays of light.
4. What would happen if the holes were smaller?
If the holes was smaller then the beam of light would be smaller and it would just stay smaller but if it was bigger then more light would be able to go through but of it was smaller less light would go through.
Well done, good detailed answers. What do you predict would happen to the light beam if you placed a mirror at the end?
Will the light refract through the paper?
I prediction that the light will travel through all of the pieces of paper and will go in a straight line.
1. The light can go through all of them because light travels in a straight direction and if nothing is going to block it then it will get through.
2. If the cards were not aligned then the light will not be able to go past.
Well done Jeremi good answer. What do you predict would happen to the light if you put a mirror at the end of the row of paper?
I will send you my video.
Thank you.
Prediction:
I predict that light travels in a straight direction.
Conclusion:
How can light be se n through tall the cards?
If it’s a glass card then light would travel through the cards because it’s just like a mirror.
What would happen if the cards were aligned?
Then light would not travel through the card because the cards are not straight.
Good work Jessica. Is glass the same as a mirror? What would happen to the light beam if you put a mirror in front of it?
1.How can light be seen by cards?
Light can be seen by cards if its in straight line and the same height.
2.What would happen if the cards were not aligned?
The light wouldn’t be able to pass through
3. What does the experiment prove about the path light travels?
If its not the same it wouldn’t be able to pass throught the cards
4.What would happen if the holes were smaller?
Nothing will happen it would still pass throught but smaller amounts
instead of big amounts.
So in conclusion, how does light travel? in straight or in a wavy direction?
Why would the light not pass through if the circles were not aligned?
I predict that light travels in a straight line.
My prediction was right. Line does travel threw a straight line. I know this because I have done an experiment on it.
Well done. What would happen to the light if one of the pieces of paper didn’t have a hole in it?
I have done the experiment in school.
Well done Shree. What did you learn?
I will send my work.
Thank you, well done.
1. How can light be seen through all the cards?
By outing them all straight and.
2. What would happen if the cards were not aligned?
The light wouldn’t come through because it wouldn’t travel straight.
3. What does the experiment prove about the the path light travels?
That they go straight.
4. What would happen if the holes were smaller?
The hole would travel differently
Predict:
I predict that light travels in straight direction.
Conclusion:
1.If the cards were not aligned then the light wouldn’t go through it because the circles are not in line.
2.If the wholes were smaller the light wouldn’t go through it.
I predict that light travels in wavy directions
Conclusion:light can go through cards a tiny bit if cards weren’t aligned light could go through cards.The experiment is put a hole in the middle and put light through light wouldn’t go through
Aim
To test and experiment with light to see if physics behind light
I predict the light will travel through straight I think this the light will be able to go strait
Material
Blue tack
Torch ruler scissors
It finds the opening and goes through
They won’t travel trough
It would be harder to travel through
Aim:
To discover how light travels and learn about the physics behind light.

Conclusion:
1. How can light be seen through all the cards?
Light can been seen if you put a hole in each cards and then lights travels.
2. What would happen if the cards were not aligned?
The light doesn’t travel through the holes.
3. What does the experiment prove about the path light travels?
The light travels in a straight line.
4. What would happen if the holes were smaller?
The light won’t travel through properly.
Hypothesis:I predict the lights will be wavy when they go through the hole.
My prediction was wrong because the lights actually go straight.
Conclusion:
1)if the holes are levelled propely,the light will go straight.if the holes are too small the light will not go in.
2)Then the light will not go in and if the paper is levelled,the holes are
levelled.
3)The experiment proves that the light will and does go straight.
4)If the holes were small the light will not go through.
Hypothesis:
I predict light travels in a wavy direction.
Materials needed
3 pieces of paper/ card
Blu tac
Torch
Rulers
Conclusion
1) it could be seen because there were holes meaning the light could go through
2) if they weren’t aligned it wouldn’t work and it wouldn’t go through.
3) we proved that lights travel in a straight lines
4) if the holes were smaller then it wouldn’t work
Prediction (Hypothesis):
I predict light travels in a straight direction.
Method:
In this experiment I drew a line from corner to corner creating a big X on 3 papers. After, I put the papers together and poked a whole through the middle of the paper. We got blue tack and stuck them to the bottom of the paper and then put them on the table in a straight line. Then I got a torch and bended down onto the floor and I shined the light through the wholes and got my conclusion.
Conclusion:
I predicted that light travels in a straight line and I was correct. I know this because the wholes were in a straight line so the light was able to pass through the wholes. However, if the wholes were not in a straight line the light would be blocked and it would no longer be able to travel. Therefore my prediction was correct.
Hypothesis
I predict that light goes in a straight direction
Conclusion
My prediction is correct light travels in straight line.
1. How can light be seen through all the cards? Light can travel though card by going though the holes
2. What would happen if the cards were not aligned?
The light won’t go through the holes.
3. What does the experiment prove about the path light travels?
It proves that light travel though a straight line
4. What would happen if the holes were smaller? The light won’t go through the hole because the holes are small.
1. How can light be seen through all the cards?
Light can be seen through all cards by having a hole in them so the light can pass through in a straight line.
2. What would happen if the cards were not aligned?
If cards were not aligned then light can’t travel through a straight line and neither will it work.
3. What does the experiment prove about the path light travels?
The experiment proved that light travels through a straight line
4. What would happen if the holes were smaller?
If the holes were smaller it wouldn’t permit light to pass through it.
Aim:Learn about the physics of light and how it travels.
Hypothesis:I think the light will travel in straight lines.
Conclusion:In order for your light to go through all the card you need to Aline it.It would just go through the first hole and just hit the next piece of paper.It proves that light travels in a straight direction.It would still go through the holes but less light will go through the holes.
I predict that light travels in straight lines.
1.) Light can be seen through all the cards as the holes are aligned proving that light travels in straight lines. This is how light can be seen on the furthest card.
2.) If the cards were not aligned the light would not be able to get to the furthest card.
3.) This experiment proves that light travels in straight lines.
4.) If the holes were smaller the light would still travel in a concentrated form.
Hypotheses
I predict light travels in wavy directions.
Conclusion
My prediction was wrong. The torch I held the light went through the holes straight. If the cards where not lined properly the light would go through the first one but not the second. If the holes were smaller the the light traveled but it would be small.
A good try. We need to work on your conclusion. Check your spelling… travelled… can light bend around corners?
Nargis you haven’t explained it fully. What would happen if the holes were smaller? Would the light still be able to travel through them all?
What would happen if the light was blocked? Why do you think your prediction was wrong?
Conclusion
It seems that light travel if the cards are in straight line it will be straight and if it’s not it won’t work
What I found out in my experimenting, I found out my prediction was correct. It goes straight.
Questions.
1. I think light can be seen through cards without objects in the way and with bigger holes. So it can travel through properly to make the experiment go correct.
2. Well, if it wasn’t aligned. It would be wavy. Due to a object (card) is in the way. For example, if the middle card was a bit to the left, what the torch will do is be blocked but the wall of the card since the hole isn’t seen.
3. This experiment proves that light can be seen through objects that are not in the way. So we can find things for example our couch. Through holes if we threw something, there’s nothing in the way so it would be useful to understand this.
4. If the holes were smaller, the light wouldn’t travel through.
Be careful how you answer Yosif… it goes straight? What goes straight?
Well done, you enjoyed the experiment.
Can one bit of light bounce of another bit of light?
Prediction (Hypothesis):
I predict light travels in straight direction.
Conclusion:
1)How can light be seen through all the cards?
You have to make sure all the cards are aligned and make sure the holes are big enough for the light to go through .
2) What would happen if the cards were not aligned?
The light would be blocked so it woudn’t be able to go through as they are all wavy.
3)What does the experiment prove about the path light travels?
The experiment proves that light travels straight . It also proves that if something is blocking the light then it won’t travel straight .
4)What would happen if the holes were smaller?
If the holes were smaller the light won’t travel through as the light would be blocked .
Conclusion :
My prediction was correct . I know this because I carried out the experiment and the line went straight through .
Super Zahrah, your prediction was correct. Are light waves the same as sound waves?
Excellent work Zahrah. You have been focused and I am really proud with your attitude towards your learning. 👍🏼
Zahrah…. can light bend around corners?
Hypothesis I predict light travels in straight direction.
My conclusion was that the light traveled in a straight line.If the cards weren’t inline than it would have not traveled straight.If the holes were smaller no light would pass through.You can see the light through the cars because there are holes and the pieces of card are aligned.And If the cards aren’t aligned the light won’t go through because the light was blocked.For my prediction I was correct.This experiment proved that lights can go in a straight line unless something comes in the way and blocks you.
Great Sunnaf, why did you predict that the light travels in a straight line?
Check your spellings Sunnaf… aligned… not aline…
well done you enjoyed the experiment.
Can light travel in waves?
Prediction:
I predict that light will travel in a straight line. This is because if you see light travel wavy it is an effect or a liquid or a solid is making the light look wavy. Therefore I think that light travels in a straight line.
Conclusion:
Light can be see through all the cards by it being in a straight line.
It would still travel in a straight line but it wouldn’t go through on wolf the holes.
The experiment shows that light only travels in a straight light and not a wavy line.
The light will still travel in a straight line if the holes were smaller.
Was your prediction correct?
Yes.
I predict light will travel in a straight line.
It would block the lights view. It does not curve.
That light only travels in a straight line.
The light would get smaller.
Well done Azan.
I predict it goes in straight lines.
Why’s that?
I predict that light travels straight direction
How can light be seen through cards?
It can be seen by putting holes in card and flashing a torch in them and it travels through it.
What would happen if the cards weren’t aligned?
The light wouldn’t travel through it wouldn’t be seen when the light is trying to travel through.
What does the experiment prove about the path light travels?
It proves that the card needs to be alinged and the light needs to be in an angle for the light to travel through.
What would happen if the holes were smaller?
There would be less light to observe and experiment on.
Great work in science today Sofia! So how does light travel ?
1. Light can be seen through all the cards because the holes are in alignment and the light travels in straight line path.
2. The light wouldn’t go through.
3. The experiment proves that light travels in a straight line.
4. If the holes were smaller a smaller amount of light would go through but some light will go through.
Prediction:
I predict that light travels in a straight direction.
Conclusion:
In conclusion we found out that light travels in a straight direction. We also found out as a class that we didn’t need a torch for this experiment. This is because, if we looked through the holes and see light then in theory you would known light travels in a straight line. If the holes that were made not aligned, then you wouldn’t see the light coming out from the other side. If the circles were smaller, then you would see the light but there would just be less light.
I predict light travels in straight direction.
Light can be seen through the card if the card are straight and the holes are in line
Hypothesis
I predict light travels in a wavy direction.
Why?
My prediction is incorrect and correct at the same, This is because light travels in a straight line until it hits an object so for example if I shone a light at a chair the light would travel in a straight line but when it hits the chair it bounces off and then travels in waves.
Light can be seen through the cards because when it travels It goes through the holes in the cards. If the cards were not aligned the light would bounce of one of the cards as the cards are white.
Hypothesis.
My prediction is that I predict it will go straight or some ways wavy but I’m thinking straight.
Why would it go wavy?
I predict light travels in straight direction .
Conclusion
It can be seen because light travels in STRAIGHT lines and if all the cards are in lines then the light rays/ particles can travel .
The light wouldn’t be able to pass through
It shows that light does travel in straight lines
If aligned it might just pass through but if the hole is too narrow then nothin would pass through
1. How can light be seen through all the cards?
The cards have to be in a straight line and the same height.
2.What would happen if the cards were not aligned ?
The light wouldn’t pass through.
3. What does the experiment prove about the path light travels ?
It shows that if the card are not in straight lines or not the same height the light would pass through.
4.what would happen if the holes were smaller ?
The light would still pass through but a small amount because if there’s less space the light can’t really go through much.
Good answers well done. So how does light travel?
Because their are holes through the card
Then the light will block
Because it goes straight
It won’t go through that much
Good try Haya. How does light travel?
1.Light can be seen through all the cards if it goes through and nothing blocks it.
2.If the cards where not aligned then the light would not go through and you would not be able to see light at the end of tunnel.
3.This experiment proves that light travels in a straight line.
4.If the holes were smaller then less light would get to the end of the tunnel.
My prediction is that the light will travel through all of the pieces of card and will go in a straight line.
1. The light can go through all of them because light travels in a straight direction and if nothing is going to block it then it will get through.
2. If the cards were not aligned then the light will not be able to go past.
3. This experiment proves that light travels in a straight direction.
4. If the holes were smaller then less light will get through but you will still be able to see the light.
I have done the experiment and sent a picture of my work.
Thank you!!
Well done.
I can’t wait to hear about what everyone discovers! This is so interesting Ms Ahmed!
