Hot Air
Source Institutions
In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.
If Hot Air Rises, Why is it Cold in the Mountains?
Source Institutions
This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside
Woodpecker
Source Institutions
In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.
Investigating Ice Worlds
Source Institutions
In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.
Oh Buoy!
Source Institutions
Learners work in pairs to design, construct, and test a device that exhibits positive, neutral, and negative buoyancy. They test a number of different objects in water to see if they sink or float.
Colors of Stars
Source Institutions
In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.
A Hole in the Ground
Source Institutions
Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.
Exploration Tank
Source Institutions
This is a guide for facilitating interaction at a touch tank with marine animals. The instructions are for setting up a display in an informal science center, but could work anywhere.
Modeling Tidal Action
Source Institutions
In this activity (Lesson 1), learners work in groups to create tide simulations.
How does the Atmosphere keep the Earth Warmer?
Source Institutions
In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.
What is in the Water?
Source Institutions
In this activity, learners use open inquiry to learn about the process of science as well as gain experience regarding the Law of Conservation of Mass, dissolution, and density.
Fossil Age Estimation Model
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Dinosaurs), learners will model how paleontologists estimate the age of fossil discoveries by extracting “fossil” playing cards from newspa
Building a Community From the Ground Up
Source Institutions
In this activity, a group of learners work collaboratively to design and construct a paper model showing the evolution of an environment through multiple stages, from prehistory through the modern cit
Trash Talkin'
In this activity, learners collect, categorize, weigh and analyze classroom trash and discuss ways that engineers have helped to reduce solid waste.
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).
House Warming
Source Institutions
In this physical sciences activity, learners explore how passive solar design increases energy efficiency.
Where Does the Wind Blow?
Source Institutions
In this activity, learners investigate wind by comparing the force of wind in different locations. Learners build wind-o-meters out of wooden sticks and strips of paper.
Dinosaur Breath
Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.
What Color is Your Air Today?
Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.
Mold Mole Molds
Source Institutions
In this activity, learners make different shapes that hold exactly one mole of gas (air).
