Hi year 3,
This week we are going to make progress on our knowledge of forces and will look at friction as a force.
What is friction? Watch the video to find out.

Investigation:
Complete your investigation at home and complete the challenges below:
Bronze: What is friction?
Silver: Which surface have more or less friction? How do you know?
Gold: If I went skiing would I want there to be more or less friction? Explain.
Bronze;
Friction is the force that is difficult for one object that can slide.
Silver
Acarpet will have more friction.
Bronze: if the car move on a up way more friction if the car moves down it is less friction
Good try Aro.
Friction is a rubbing force. It can make something go faster or slower depending on the force used.if the surface is smooth the friction will be less. If the surface is not smooth the friction will be bigger and more
Bronze
Friction is when you. Add more force it moves less and If you you add less it would go more
Silver
The carpet could have more because if it was rough I could move more
Where might you see friction in action during the school day?
Bronze:
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.
Silver:
Rough surfaces have more friction than smooth surfaces and liquids such as oil or water are sometimes used as lubricants to reduce the effect of friction. There is no mystery behind friction. It acts on objects at the surfaces so as to prevent or reduce movement between the surfaces.
Gold:
The more friction, the more heat you generate instead of speed, and the slower you go down the slope. … Hot wax which is applied to the entire ski, in particular, reduces the friction between the ski and the snow, which means you can go faster down the slope. Wax is a cheap and effective way to improve your speed!
Where might you see friction in action during the school day?
Bronze
Friction is a force that slows things down.
Silver
The table has less friction because it is more smoother than the carpet.
The carpet has more friction because it is rough.
Gold
Less friction because you will be able to ski longer.
Where might you see friction in action during the school day?
bronze
friction is a force between two things that work in the opposite ways.
Silver: Which surface have more or less friction? How do you know?
carpet has more friction because it is rough
table -the table has less because it is smooth
Well done Yusuf. Now answer gold.
Nice one. Where might you see friction in action in the school day?
Bronze
Friction is a force that can slow stuff down or make them faster.
Silver
The Laminated floor Has less friction because it is more smooth.
Gold
Less because you wanna go faster.
How does friction alter speed?
gold
you would want both so you dont go to fast and fall over also if you go to small yo mite crash into somone.
Can you complete some more challenges? as this is not enough work.
Bronze
Friction is a force the slows things down.
Silver
A flat smooth surface would have less friction in comparison to a rigid surface.
Where might you see friction in action during the school day?
A friction is some thing connecting slow objects
The carpet is 4secs wooden floor was 3secs the kitchen tyle is 4secs.
Be careful with your wording as your work doesnt make sense.
Friction is a force between two surfaces that are sliding, or trying to slide, across each other. … Friction always works in the direction opposite to the direction in which the object is moving or trying to move. Friction always slows a moving object down.
silver
rough more
soft less
A better word than soft is smooth.
Bronze
Friction is a force that makes the object go down if there is more friction it makes the object go faster if there is less friction or it can make the object go slower is there is more friction.
Silver
A surface like the floor would have more friction because it is rough and hard but a table would has Les friction because it is more smoother then the floor I know this because the floor is very hard and will make it stop easily however the table Les friction because it is smooth and flat not like the floor the floor is very bumpy and hard so it will make the object with wheels slow down.
Gold
You would want less friction because is like a race and in races you have to be fast however you also need some friction in case you would also want more friction in some areas to prevent you from all of a sudden fallings
Nice one! Where can you see friction at work in the school day?
Bronze
Friction is a force between two surfaces that are sliding,or trying to slide across each.
Silver.
Rough surfaces have more friction than smooth surfaces.carpet have more friction than floor.
Gold.
For skiing you need less friction so you can go fast.
Super! Where might you see friction at work in the school day?
Great to see so much attention to detail in some of these answers!
Bronze
Friction is something that stops objects from moving.
Silver
The rug would have more friction because the rug is bumpy and rough whereas the laminate would have less friction because the surface is smooth. My car would move faster on the laminate rather than the rug.
Gold
You would want less friction because you can then move quicker and not slow down. This would be good for a race. However, you would also want more friction in some areas to prevent you from all of a sudden falling.
Super work Nuha you have shown a good understanding of learning today. Can you tell me is gravity a greater force and if so why?
A friction is a rubbing force.
Silver
A ramp because it is going downwards not upwards.
Gold
less because if it was balance you wouldn’t move.
Well done Aran but I would like you to tell me what friction does, please?
Friction makes you move by something going downwards.
Friction is a force that makes two things difficult to slide across each other’s
Ahmed watch the video again and see if you can tell me what friction is. Your very nearly there but I would like you to expand your answer. You can then go onto the silver and the gold challenges and answer those questions too. I know that you are more than capable of completing all of this task for Science👍🏼
BRONZE
Friction is a Force that makes something go foreword or backwoods.
SILVER
The flor will have more friction that means the car will stop slowly but go faster.
GOLD
You would want it to have more Friction.
Maryam does friction slow things down or makes this gs go faster?
4,3 and 3
A friction is a force that slows down an object.
Something smooth so then it has less friction but if it was more it wouldn’t go that far
You would want Less friction so you could go far.
Rayyana why would you need less friction for an object to go further?
BRONZE
Friction is a force between two surfaces that are sliding, or trying to slide, across each other.
SILVER
I pushed my car on the carpet and laminate floor.
Carpet has more friction than the floor. because it moved long distance on floor than the carpet.
GOLD
If I went skiing I would need less friction because then I can move faster.
Good Girl Mehreen can you tell me why you think it might be that your car would travel slower on the carpet than your laminate flooring?
Because laminate has less friction and it is smooth.
Bronze;
Friction is the force that makes it difficult for one object to slide along the surface.
Silver;
A carpet will have more friction that means the car would move slowly and stop however if you had tiled place and you used the car there would be less friction and the car would go more faster.
Gold;
There would be less friction because would be easier to ski and to turn when you hit the slopes.
Great answers well done!
