Moving Chalk Shadows

Step 1: Lets get started!

Use your blocks to make some interesting shaped buildings. Place a piece of tape down on the floor and line your building up along the tape. This is important if you are going to measure the changes in future steps, or if they simply fall over.

Step 2: Let the trace begin!

Trace around your buildings with the chalk. Record the time of day that you traced your shadow.

Step 3: Keep an eye on the shadow!

Come back later and retrace your shadow. We waited an hour and noticed a significant movement in the shadow.
