Let's Make a Solar Car
Students transform a car that they have built out of K'NEX into a solar car. Students add one or two solar cells to the car to power a DC motor then connect the motor to the car and come up with a method to drive the car. This is the...

TE Activity: Racing with the Sun - Creating a Solar Car
Students use a purchased kit to build a solar powered car. They connect a solar photovoltaic panel to a motor which runs the car forward and backward. They determine how to wire the car to move in both directions.

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...
National Nanotechnology Infrastructure Network
Hiding Behind the Mask
Microchips are a man-made wonder. Investigate the manufacturing wonder with a hands-on inquiry-based lesson. Scholars simulate the process of pattern transfer using photoresist. Their conclusion identifies how their process replicates...

Battery Charger
Students explain how battery chargers work. In this physics lesson, students discuss the two main ways that vehicles get charged. They build their own battery charger.
Curated OER
One-Way Valves
Learners explore how the heart pumps blood through its valves. They observe fluid moving through a one-way valve and build a model of a valve. in addition, they explore biotechnology design.
American Museum of Natural History
Life in the City
Believe it or not, biodiversity exists even in areas of disturbed habitat. An interactive activity challenges learners to look for species with a magnifying lens in an image of a city habitat. Pop-up images and descriptions explain how...
Curated OER
From Sunlight to Electric Current
Students explore concept of current in electrical circuits. They examine how energy from the sun can be used to power everyday items, including vehicles.
Curated OER
Production Methods
Students examine the different methods of production. They relate the new concepts to different production contexts. They identify the external factors that influence firms.
