Mr. Thomas is teaching his students about the position of the sun in the sky related to objects on Earth. Mr. Thomas has asked his students to plan an investigation to learn more about this. Which investigation below would be the best choice?

• Students can look at the sun at noon and record what they see in their journals. They would repeat this observation at noon for 3 days. 

• The students can put a stick in the ground, observe its shadow at 3 different times of the day, and record their observations

• Students can go outside to play on the playground at different times of day and record how many clouds are in the sky. 

• Students can take the temperature at 3 different times during the day and record this data in their journals.

 A student observes that the Sun “appears to move” across the sky a shadow appears and changes throughout the day. What would the student conclude after investigating that the shadow changes throughout the day?

• The students will observe the shadows are large in the mornings, small in the afternoon, and large again in the evening.

• The students will observe that the shadows change from ovals and circles throughout the day.

• The student will observe that the shadows change locations, but not size.
