Take 10 minutes to prepare your students for the webinar by setting expectations and helping them gather supplies. Educators will do a demonstration, so it's fine if each student doesn't have their own set!
a flashlight
2-3 different toys
Brainstorm:
Where have you seen shadows before?
Do shadows change over a day? How do they change?
Explore further how the Sun’s path across the sky changes how your shadow appears by watching the video below.
The Sun’s position changes over the course of the day as it appears to move across the sky. This means the shadows cast by the Sun’s light change throughout the day, too. By tracking your shadow, you can make your own sundial.
Please note: This activity requires at least 3 hours and can be done over 2 days.
