The hypothesis is that the position of the sun can be used to tell time.

You will make a sundial using a styrofoam cup, a straw, a compass, and other materials. You will then use the sundial to tell time.

You will need a styrofoam cup, a straw, a compass, a permanent marker, a pencil, tape, and some small pebbles.

After making the sundial, you can use it to tell time. You'll need to find a spot in the sun and use the compass to point the sundial north. Then, you'll mark the shadow of the straw on the cup lid every hour until 3 pm. The next day, you can compare the shadow to the marks to tell time.

This science project is interesting because it teaches you how to tell time using the sun, just like people did hundreds of years ago.

Experiment variations to consider include using different materials to make the sundial, or using the sundial to tell time at different times of the day.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
