The Sun and Shadows
As an infant teacher, I would keep this activity really simple. To start I usually use torches and a variety of shaped objects. I let the children experiment themselves in pairs to see what shadows they can make. They also use different coloured paper as a surface.
I find the interactive whiteboard great for the next step. With just the bulb and the white screen children can stand in front of the screen one by one with the whiteboard light behind them acting as the sun. They can make different shapes with their bodies and watch their shadow on the screen.
Next it would be nice to take this activity outside on a sunny day and to use their bodies and a variety of objects to make shadows using the sun as the source of light.
They could record their results on the I pads using Chatterpix and then share to the class when back inside using Bytello share. These two apps are my go to with infants. They are a fantastic resource.
Extensions of this lesson could include drawing around partners shadows using chalk and creating a simple sundial with a bucket and stick and observing how the shadow moves throughout the school day.
