Switcheroo

Did you know light can decrease visibility? Light pollution absolutely makes it more difficult to see stars. Scholars build a simple magnitude reader to determine the magnitude of stars. They use these data to estimate the impact of...

Ahoy, matey! Here is an engineering expedition that mini mariners are sure to be swept away by! After reading a brief description and history of periscopes, they work in crews to construct one. Use this activity to enhance a lesson on...

Fifth graders investigate simple circuits and identify when a circuit is considered opened or closed. In small groups, they experiment with wires, batteries, and light bulbs to identify how to light the bulb. Students also experiment...

Using a guided lesson, pupils learn about what it takes to make a circuit along with a switch. They build a complete circuit under the direction from the teacher and identify each of the elements of the circuit. Scholars then learn to...

Lights out! Scholars build on their understanding of a simple circuit by adding a switch and creating schematic drawings. The eighth lesson in a series of 14 has pupils use everyday materials to create circuits and make observations as...

After reading a short paragraph on how electrical switches work, learners look at four examples of electrical circuits, and circle the ones which will allow a lightbulb to be lit. This would be a good precursor to having your charges...

This PowerPoint includes a quiz show game in which two teams compete for points received by answering questions about simple machines. The content reviewed includes the types of simple machines, identifying examples of simple machines...

Through inquiry and exploration, 4th graders will learn and understand the functions of open and closed circuits. They will break into 2 groups, define vocabulary, hypothesize how to light a bulb, then test their hypothesis 4 different...

With a Florence flask or fishbowl, make a double convex lens and use it to examine an image. Because of the refraction, the image will be inverted. A simple explanation is provided here for you to share with your class as they...

Turn off the lights! That's right it's time to start thinking about conservation and saving electricity. Here is a very quick and very simple Earth Day craft that kids can do in a wink. They'll make light-bulb-shaped door hangers that...
