Science at the Waterpark!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.
Hockey Stick Power!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Hockey) is a full inquiry investigation into how a hockey stick’s flex affects shooting power and accuracy.
You're Grounded
Source Institutions
In this engineering activity, learners test the stability of towers they build out of cups, discovering that structures with more mass in the base are more stable.
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.
Plastics the Second Time Around
Source Institutions
In this activity, learners test and compare the physical properties of thermoplastic polymers. Learners compare different plastics based on their color, degree of transparency, texture, and density.
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.
Let's Make Molecules
Source Institutions
In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).
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?
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.
Dusting For Fingerprints
Source Institutions
In this activity, learners become detectives and use chemistry to investigate fingerprints.
What's Your Blood Type?
Source Institutions
In this activity, learners perform a simulated blood test procedure.
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.
Toast a Mole!
Source Institutions
In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!
Wind Tunnel
Source Institutions
Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.
