Solar Water Heater
Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.
Investigating and Using Biomass Gases
Source Institutions
In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.
Cake by Conduction
Source Institutions
In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.
Conductivity: Salty Water
Source Institutions
Water, whether fresh or salty, serves as one of the best electrical conductors on the planet. Does salt effect its conductivity?
Fast Rusting
Source Institutions
In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.
Detect Solar Storms
Source Institutions
In this activity, learners build their own magnetometer using an empty soda bottle, magnets, laser pointer, and household objects.
Paper Tape Motion Timer
Source Institutions
In this activity, learners build a recording timer made from simple materials (e.g., small dc motor, sharpie pen, craft sticks, adding machine paper tape, etc.).
Wind Power: Creating a Wind Generator
Source Institutions
This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.
As the Rotor Turns: Wind Power and You
Source Institutions
In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from
Electricity: Fruit Batteries
Source Institutions
In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.
M&M® Model of the Atom: Edible Subatomic Particles
Source Institutions
In this activity, learners use colored candy to represent subatomic particles and make a model of an atom (Bohr model).
Waves: An Alternative Energy Source
Source Institutions
In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.
What's the Matter
Source Institutions
In this activity, learners identify different classes of matter based on physical properties.
AM in the PM
Source Institutions
In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.
Build a Giant Puzzle!
Source Institutions
In this activity, learners assemble large cubes to make nano-related images. Learners discover how different objects are related to nanoscience and nanotechnology.
Balloon Nanotubes Tabletop
Source Institutions
This activity introduces learners to the structure and properties of carbon nanotubes.
Invisible Investigations
Source Institutions
Using indirect observational methods, learners distinguish between charged and uncharged objects.
Exploring Forces: Static Electricity
Source Institutions
In this activity, learners investigate what happens when you build up static electricity on plastic balls.
Exploring Materials: Graphene
Source Institutions
