Seventh graders simulate a Jeopardy game to examine the chemical nature of water. Among the topics featured are evaporation, water, salt, and temperature. finally, as review, 7th graders answer a battery of questions presented by the...

Clever! Earth science learners construct a model of a planet containing a magnetic core. The planet, Terrabagga, is made out of a paper grocery bag, magnets, a dead D battery, and rubber bands. Pictures of each step of the construction...

One way to identify possible volcanic activity on other planets is by testing the planet for magnetism. A science instructional activity begins with pupils constructing their own planet from a dead battery, magnets, paper, and...

Ninth graders examine the electrolysis of water by completing an experiment.  For this water lesson students will explain how hydrogen can be extracted from water and how energy flows through an electrolysis system. 

Students measure the electric potential of 9 volt batteries using oscilloscopes. They draw a diagram of the front panel of the oscilloscope, conduct the experiment, and create a graph of voltage versus the number of batteries.

Learners experiment with radio transmitters. In this transmission of waves lesson, students use an FM radio, an attenuate, and the frequency to locate a radio transmitter. Learners discuss outcomes. 

This interesting science lesson is about the compass. Students make a compass out of a magnet, sewing needle, cork, and a glass dish. The lesson includes both a pre and post-test for the students to take, and some very good links to...

Students produce copper metal by electrolysis. In this REDOX lesson plan, students use a copper (II) chloride solution and a 9 volt battery to produce copper metal through an electrolysis reaction. Students make observations and take...

Students explore the relationship of resistance, voltage, and current in series and parallel circuits using a computer model of a circuit board. They discover Ohm's Law by constructing series circuits.

Young scholars construct a homopolar motor following certain procedures. In this physics lesson, students explain how generators and motors work. They compare and contrast the characteristics of both.
