Light & Dark - Drawing Shadows

Target: Look for and measure shadows, find out how they are formed and what might cause the shadow to change.

We went on a shadow hunt around the house to see where there were shadows and why - what was blocking the light? Where was the light source?

On a piece of A4 white paper, I placed a toy animal on it and we used a lamp to create its shadow. I drew around the shadow (narrating what I was doing, including how difficult it was to not knock over the toy, or to see exactly where the shadow was when my hand's shadow got in the way, and look, I made a mistake here but never mind! - F, in particular, is still working on her growth mindset when it comes to difficult things and getting things wrong...) and coloured it in lightly with a coloured pencil. Then I repeated this process with different figurines and colours, overlaying shadows on purpose, to create this abstract artwork - revising earlier work on colours and blending.


They experimented with where they wanted to place the toy in relation to the light and saw how the shadow changed size or stretched. To make things fair, they kept switching seats so they could take turns being nearer or further away from the light source.





I wasn't expecting Z to write the title on hers, but she did while I wasn't looking and was very pleased with herself!

When they were done, they used their drawings to play a quick game of "guess the animal" with each other. 😄

We discussed how to make a simple sun dial, recapping their knowledge on space and how the Earth rotates to create day and night. The book on Light and Dark in the KS1 Science series we have has a few pages on the subject which we read through together.

Before we made our sun dial, we recreated the theory behind how a sun dial works using a lamp to show how the shadow changes in quick time, moving across the ground, as the sun "moves across the sky". I had them predict what they thought the shadows would look like in the morning and evening and what time they thought it would be when the shadows are at their shortest (they correctly guessed stretched out and around midday!)

We tried making our own using paper plates with a pencil blu-tacked in the centre, but the weather this time of year was too overcast to see the shadows clearly. We might try again in the summer InshaAllah, but on a positive it was a good discussion point on whether sun dials were effective all year round or in all weathers!

We drew some simple 3D shapes and learnt about shading to create a 3D effect. We started with a sphere, then a cone and finally a cube. We talked about where the shadow would be in relation to the light source in the picture. We also tried doodling other pictures, e.g. a tree, and I showed the girls how to draw simple prisms (recapping that a prism has the same 2D shape at each end!).

I bought some 3B pencils for this purpose and the girls discussed how the lead felt softer than their HB writing pencils and why it was easier to draw with the 3B pencil. They experimented with using different pressures to create lighter and darker effects.

Finally, we watched The Gruffalo's Child (which happened to be on Amazon Prime) and talked about why the shadow was so large even though the mouse was so small! To help reinforce the point, we took out the torches again and played around with making shadows on the wall. 😁
