Look at the shadows and make a prediction. Why do shadows sometimes look so much bigger or smaller than we are? Explain your answer.

Use all the sentence starters to write your sentences:

Shadow Investigation

We noticed a pattern in the length of the shadows in the video as the sun moved. Today, we are going to investigate how the position of the sun affects the length and direction of shadows throughout the day by shining a light from different locations.

Now, we’re going to investigate! Use the following materials.
1 Flashlight
1 Figurine/Small Object
1 Shadow Tracking Paper (blank paper)
Procedure:
Put your small object in the center of the paper.
Starting on one side of the object, shine the light in an arc over the object.
Notice how the shadow length and direction change at each of the five spots.
