UV light & Ozone layer
Middle-school meteorologists absorb information about ultraviolet radiaton and consider the ozone layer. The book that learners are supposed to refer to is not available, so you might want to locate some graphics or posters...
Curated OER
Switcheroo
Students construct a simple switch and determine what objects and what types of materials can be used to close a switch in a circuit and light a light bulb.
Curated OER
Circuits
Fifth graders discover the differences between parallel and series circuits. They draw and construct the two types of circuits using wires, bulbs, batteries, sockets, and switches.

Basic Circuits
Students explain the difference between a closed circuit and an open circuit. They construct simple to more complicated series and parallel circuits. They explain the difference between a series and parallel circuit.
Curated OER
What is the Underlying Causality of a Simple Circuit?
Young scholars explore simple circuitry. They compare four models of circuits and explain how each works. Students contrast the cyclic cequential and cyclic simultaneous models using a shower curtain illustration and software simulation.
Curated OER
TE Activity: Does Weight Matter?
Young scholars design and conduct experiment to determine if weight added incrementally to an object affects amount of friction encountered when it slides across a flat surface. They graph data from their experiments, and calculate...
