1. The lesson plan introduces 2nd grade students to how shadows change throughout the day. Students will make observations of their own shadows at different times and record the length and position.
2. In groups, students will draw around their shadows with chalk multiple times during the day to see how the shadows change position and length. They will also note the position of the sun.
3. By observing and recording the length of their shadows every hour, students should recognize that shadows get shorter at midday and longer in the morning and evening, relating to the sun's position in the sky.
