Look, then try.
The picture shows the whole trick. A shadow appears when something solid gets in the way of light: the light travels out, hits your toy and stops, leaving a dark shape behind it. Try it with a torch or a lamp in a dim corner. Move the light closer and your shadow grows tall; move it further away and it shrinks. Move the light to the side and the shadow stretches away from you like a long path. Shadows are not fixed: they change every single time the light changes.
Move lamps and torches with dry hands and keep them away from curtains and paper. Never look straight into a torch or the sun, and never stare at bright light. A grown-up dims the room and stays nearby, and an adult comes outside with you. Rest your eyes often, and nothing goes near your mouth.
Use a finger, stylus or mouse in each drawing box. Type below it, or ask a grown-up to write your words. Your work stays in this tab. Save before refreshing or leaving.

What are we learning?
Light travels in straight lines, and a shadow is the shape where something blocks it. Moving the light and watching the shadow change is early physics: predicting, testing and describing what you see.
