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.
Crime Scene: The Case of the Missing Computer Chip
Source Institutions
Learners use scientific processes to solve a crime. As they get clues, learners must create a hypothesis then adjust that hypothesis as more information is revealed.
Fruit Juice Mystery
Source Institutions
In this chemistry challenge, learners work to figure out which of four juices are real, and which is just food coloring and sugar.
Trash Talkin'
In this activity, learners collect, categorize, weigh and analyze classroom trash and discuss ways that engineers have helped to reduce solid waste.
How Do Things Fall?
Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.
Can Crushers
Source Institutions
In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.
Illuminating Luminescence
Source Institutions
In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.
Geometry Construction: Polyhedral Playthings
Source Institutions
In this activity, learners create 3D geometric shapes using straws and pipe cleaners.
Investigating and Using Biomass Gases
Source Institutions
In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.
Size and Scale: Probing and Predicting
Source Institutions
In this quick activity about predicting (located on page 2 of the PDF under Where's Nano?
Determining the Amount of Transpiration from a Schoolyard Tree
Source Institutions
In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.
Insulators and Conductors
Source Institutions
In this activity, learners explore the concept of conducting or insulating electricity.
Ice Cream
Source Institutions
In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.
Counting Books: Make Your Own!
Source Institutions
On the first night, I saw 5 stars in the desert. On the second night, I saw 10… What do you think I saw on the third night? Combine arts and crafts, literacy, and math by making a counting book.
Floating Butterfly
Source Institutions
In this activity, learners create a cool floating animal using the science of magnetism. Learners discover what happens when a piece of magnetic metal enters a magnet's field.
Simulation of Laparoscopic Surgery Lab
Source Institutions
This simulation of laparoscopic surgery enables learners to practice and to learn this modern surgical technique.
Guiding Light
Source Institutions
In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).
House Warming
Source Institutions
In this physical sciences activity, learners explore how passive solar design increases energy efficiency.
FlyBy Math: Distance-Rate-Time Problems in Air Traffic Control
Source Institutions
In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.
Haunted by Hurricanes: Use Data to Learn About Hurricanes
Source Institutions
In this activity, learners will determine if the frequency and intensity of hurricanes are changing using real data from the National Hurricane Center.
