Earth Atmosphere Composition
Source Institutions
In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.
Our Solar System to Scale
Source Institutions
In this activity, learners plan and create a 24-foot long, two-dimensional model of our solar system, and compare and contrast the differences between planets and the sun.
Atmosphere Composition Model
Source Institutions
In this activity, learners create a model using metric measuring tapes and atmosphere composition data.
Special Effects: Titanic and Beyond
Source Institutions
In this activity, learners investigate how geometry plays a role in perspective.
The Pull of the Planets
Source Institutions
In this activity, learners model the gravitational fields of planets on a flexible surface.
Build a Solar System
Source Institutions
In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei
Three Little Pigs
Source Institutions
In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.
Building Houses: Build a Cardboard Tube House
Source Institutions
Build a house you can fit inside, using cardboard tubes.
Shaking It!
Source Institutions
In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.
Dunking the Planets
Source Institutions
In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.
Giant Museum: Create a Scale Model
Source Institutions
In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?
Newton Car
Source Institutions
In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.
Rocket Wind Tunnel
Source Institutions
In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.
Lift Off!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.
Solar System in My Neighborhood
Source Institutions
In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.
Water Body Salinities II
Source Institutions
In this activity, learners discuss the different salinities of oceans, rivers and estuaries.
The Parachuting Egg
Source Institutions
In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.
