The Nature of Salt
Students record information from the periodic table for sodium and chloride. They determine whether salts are molecular or ionic compounds, along with sodium chloride's molecular weight, and relative weights
Cornell University
Electroplating
Silver pennies and copper nickels are made possible by applying some chemistry. Learners use electrolysis to coat a penny with zinc sulfate and a nickel with copper sulfate. Their investigation builds an understanding of electroplating...

Wind Power for Educators
Students explore wind power as a renewable resource. In this wind power lesson students build models of wind turbines and experiment with different changes to see if it increases efficiency.
Curated OER
Magnetic Domain
Students participate in activities in which they examine magnetic domains. They analzye how different colored metals and how they react to magnets.
Curated OER
Plotting a Magnetic Field
Pupils experiment with a set of materials. They plot the magnetic field that arises from a regular bar magnet. They discover how a magnet affects a compass.

Bungee Man Lab
Students explore the motion of a toy bungee jumper using the scientific method. They view a video of a bungee jumper and discuss what can be measured about a bungee jump. Students discuss the scientific mehtod and how to design an...
Curated OER
Conductors, Insulators, and Semiconductors
Students will investigate the differences in conductivity of materials, design a variety of complete circuits, and observe the differences between the manner in which light is produced in an incandescent light bulb and an LED.

DC Motors
Twelfth graders build simple electromagnets and small motors using a motor kit in order to illustrate how magnetic fields are produced by a current carrying wire and how an external magnetic field produces a force on a current carrying...
Curated OER
Hybrid Automobiles
Students explain the basic principles of gasoline engines as propulsion for vehicles. They cite reasons why alternatives for gasoline engines are being considered and explain differences between a motor and an engine.
Curated OER
Blast's Cosmic Carnival
Students, after analyzing the history of a concentrator, model how a Genesis spacecraft concentrator works by playing a game. In groups of three or four, after being given materials to work with, are challenged to roll the rubber balls...
