Wednesday 13th May- 3B Home Learning- Science:To understand how shadows are formed

Hi Year 3,

Today for Science we are going to look at what shadows are and how they are formed.

What is a shadow?

Watch the video below to help you understand how a shadow is formed.

What is a shadow? For a shadow to be formed an object must block light. The object must be opaque or translucent to make a shadow. A transparent object will not make any shadow, as light passes straight through transparent objects.

The power point below will help you understand shadows better.

Watch the video below and note down any keywords.

Now complete the activity set on Education City called ‘Shadows.’ This activity will only work on a laptop.

CHALLENGE

Complete the shadow experiment. Start by checking the weather. This activity needs a day with full sunshine, so pinpoint a good, cloud-free day.

First thing in the morning (if the sun is out) go out with some chalk. Find a good spot where there won’t be any shadows from trees or fences and make a cross. You will need someone to help you. Get someone to stand on a cross. Draw around the shadow and measure how long it is. Repeat this every hour.

Draw a table like the one below and record the results.

Time taken (Hours/minutes)     Length of shadow (cm)

9 hr 10 mins                             87cm

What did you find out?

  1. Hi Miss, a shadow is formed when the light source is blocked by an opaque or translucent object, the light source can be natural or man made ( ☀️ or a 💡).

  2. Hi Miss, I have completed my work on Education City.

    I have noticed that the sun was shining from the south and the shadow was pointing north. Later the shadow was pointing towards the east and the sun had also moved towards the west. This is like a clock moving around. I did also see that the shadow before was bigger before.

  3. What is a shadow?
    A shadow is when light reaches a person or object it creates a shadow because it cannot go through a person. (The person is opaque)

  4. A shadow is a reflection.If it is dark and you want to see your shadow, just shine light 💡 on the wall (or anything else) and stand in front of the light to see the shadow.

    Education city does not work on the phone either.

  5. A shadow is a dark (real image) area where light from a light source is blocked by an opaque object. It occupies all of the three-dimensional volume behind a object with light in front of it. The cross section of a shadow is a two-dimensional silhouette, or a reverse projection of the object blocking the light.

  6. Good girl for letting us know.
    Please tell us what you need help with. Watch the video again please Gufran.
    Please go in your garden in a sunshine and look at your shadow. Ask a family member to draw around your shadow.
    Let me know Gufran if you can do it.
