Cardboard Tube Pinhole Projector

Scientists have theorized that our solar system formed 4.6 billion years ago. In this pair of activities, learners first hypothesize how our solar system was formed. Using this information, groups then determine how scientists search for...

A tube worm's outer covering is made of chitin, the same material that makes up the shells of lobsters and crabs. Scholars create tube worms and analyze and discuss the longevity of organisms living near cold seeps. They then discuss and...

You won't have to force your classes to complete these engaging activities! Through exploration, young scientists learn that force has both magnitude and direction. They draw force diagrams, investigate force models, and complete a...

Third in a set of lessons regarding reservoirs, dams, and hydropower, this involves a two-day hydropower plant simulation. Collaborative groups build, maintain, and finance the plant. The transparency of the reservoir setup can be...

The earth only revolves around one thing — and it's not any of your pupils. The lesson includes two activities dealing with the distance to the sun and the moon. First, scholars create a pin hole camera and use the rules of similar...

Students explore light.  In this light wave physics lesson, students construct periscopes, kaleidoscopes, color wheels, and pinhole cameras.  Students observe and record characteristics of light demonstrated through the use of these tools.

Young scholars observe a demonstration on light. They construct a pinhole viewer, and explore and discuss the concept that light travels in a straight line.

Students create a periscope by forming a rectangular box by cutting and folding with poster board.

High schoolers engage in a lesson which includes flame tests and the construction of a simple diffraction spectrograph with which to measure sodium ion emissions. They use the Bragg equation to compute the wavelength of the line spectra...

Albrecht Durer created a highly textured stamp or print of a rhinoceros. To better understand which animals are near extinction, upper graders create similar prints of endangered animals they've researched. The six-day instructional...
