Sundials: Observing and Using Shadows

Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

By using the Internet, hands-on activities, video, and cooperative learning, pupils look into the conditions in which light casts shadows on objects. The lesson includes fabulous hands-on activities, art projects, worksheets, and reource...

Can people really measure time just by using the sun? Scholars venture outside on a nice, sunny day to build sundials and learn how people measured time 600 years ago. The class builds two different sundials while gaining practice with...

If you have taught the first lesson in this mini unit, learners already know that cabbage juice and vinegar cause chemical changes in some materials. Now, they get a chance to use them to compare the liquids' reactions to five known and...

Shine some light on the topic of seasonal change with this collection of activities. Whether it's by measuring the change in the length of their shadows, or modeling the earth's orbit around the sun using a lamp and a globe, these simple...

What causes a shadow to appear? Have kindergartners and first graders explore shadows with a fun science activity. After reading a short paragraph about light sources, they draw a shadow for a little girl based on the location of the...

Third graders study the three states of matter and identify the physical changes that take place between them. There is an initial teacher-led demonstration followed by a meaningful whole-class inquiry. These two activities should lead...

Integrate math, science, and speaking/listening with a collaborative hands-on activity. Each group works with a single penny, examining it with the naked eye and recording observations. Repeat using magnifying glasses. Then repeat with a...

Students demonstrate understanding of shadows by creating a physical model of concepts taught.

Students explore space science by conducting a sun experiment in class. In this time telling instructional activity, students discuss how the sun sits in our sky at exact times each day and how astronomy is based on our perspective of...
