What's the Attraction?
Students experiment with magnets to determine the distances at which they attract and repel each other.
Curated OER
Circuit Boards
Students explore circuit boards. They determine that a complete circuit is needed to light the bulbs, experiment with the boards to develop strategies for finding where the hidden connections are, and develop strategies that can be used...

The Conncection Lesson
Fourth graders see how electricity can flow through objects and can be used to do work. They construct a working circuit of their own and explain why it is able to do work. They get students familiar with what it takes to create a movie.
Curated OER
Static Cling
Students work together to discover the concept of static electricity. They participate in an experiment in which they test different objects charge. They make observations and record them for later use.

Sticky Books
Fourth graders investigate items that are magnetic and those that are not. They determine the properties of the magnetic items. They create a digital book that demonstrates what they have learned about magnetism.
Curated OER
Am I Sticky
Fourth graders become familiar with magnets and their properties. They investigate what items are magnetic and non-magnetic and make generalizations about the properties. They utilize technology to develop an interactive digital book.
