This science project has to do with space, more specific, the sun. It's called "Sun Shadows." It's an activity that teaches kids how the sun tells us what time it is.

The things you need are:

White paper

Note pad (Activity log)

Large paper clip

Pencil

Transparent tape

What to do:

#1: Bend one side of the paper clip to make a stand.

#2: Stick the paper clip through the center of the paper.

#3: Tape the base to the back side of the paper.

#4: Place the paper on a flat, smooth surface where the sun will shine on it. Make sure it won't be disturbed all day. Use tape or a pencil to mark the paper's exact location on the ground or table.

#5: At 10:00 A.M., carefully trace the paper clip'sshadow. Put a heavy dot on the tip of the tracing. Repeat at 11:00 A.M., 12:00 P.M., and 1:00 P.M. Label your tracings with the times.

#6: Predict where you think the tip of the shadow would be at 9:00 A.M. and at 2:00 P.M. Mark these predicted points on the paper.

#7: Return the paper to its marked location the next day. Trace the actual shadows at 9:00 A.M. and 2:00 P.M.

Ask the following questions to your 4th graders and have them write their observations in their Activity log.

What Happened?

1. On the 1st day, what did you observe? What did the shadow do?

2. When was the shadow longest? When was it the shortest?

3. How much did the shadows change from the 1st day to the 2nd day?

What Now?

1. How could you use a shadow to tell the time of day?

2. Does the change in the shadow length from day to day create a problem with telling time? Explain your answer.

3. How accurate were your predictions? What could you do to make them more accurate?

4. How could you tell the time on a cloudy day?

5. What patterns in the sky affect shadows?

Hope you have fun with this project!
