How Smart are You about Electricity, Batteries and Conductors?
Young scholars create working circuits. In this electricity and circuits lesson, students make a battery, then build a flashlight and use part of the flashlight to create a conductivity tester.

Make a Battery From a Lemon
Fifth graders construct a voltaic battery. They change chemical energy into electrical energy by inserting copper wire into a lemon. They discover the tingle of the wire on their tongue is due to the movement of electrons.

Citrus Batteries
Students create models of voltaic cells using lemons. They place both a copper strip and a zinc strip into a lemon about a half inch apart and touch both leads at the same time to their tongue. After recording their observations,...

Transformation of Energy
Sixth graders explore and discuss how several electrical devices work and what energy conversions occur in each device. They connect a zinc strip to a copper strip with alligator clips and wire, immersing each strip in lemon and check...

Acids, Alkalis, and pH
In this pH worksheet, learners determine how indicators work and what the pH scale is used for. Students learn what happens when non-metals burn in air and when metal oxides dissolve in water. This worksheet has 10 problems to solve.

Acids and Bases
Students study acid and bases and how they fall on the pH scale. In this solutions lesson plan students complete a lob activity using litmus then fill out a data table.
