3 Blues shadow investigation.

In 3 Blue this term we have been looking at light sources and today we created a human sundial to explain how shadows change throughout the day.

We predicted when the longest and shortest shadow would be and then we went out side to investigate our predictions. We drew around one of our classmates shadow and recorded the time and direction, we did this in the morning, at lunch time and in the afternoon.

Take a look at our short video below.


  1. Explain how a shadow is created?
  2. Why is a shadow different lengths at different times of the day?

    A shadow is created by the sun
    Because you have eaten dinner and dinner sometimes makes you become older

    1. Its basically an object that is blocking light
    2. It’s different lengths because the earth orbits the sun and the earth tilts so at 9:30 it was 2m.20 and at 11:45 it was 1m.15 and at 2:00 it was 2m.25

    A shadow is created when an opaque object bloks a source of light.
    Because the Earth is moving.

    It’s a object that blocks the light sore from not going pas through easily so it makes a shadow

    1. Shadow is made from the sun blocks a person and when it’s sunny you will see your shadow
    2. Because it might be in different places.

    1.Basically its a object that blocks the light source and if its opaque then it does not allow light passing through it.If it is translucent some light allows to go through it. And finally if it is transparent light allows it to pass through.
    2. It is different lengths because the sun moves different heights and the more higher the sun is the more shorter the shadow is.The more lower it is the more bigger it is.
