Multiple Reflections
Source Institutions
In this activity, learners explore how mirrors reflect light and change the way we see things.
Sliding and Stuttering
Source Institutions
Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.
The Thousand-Yard Model
Source Institutions
This is a classic exercise for visualizing the scale of the Solar System.
Modeling the Seasons
Source Institutions
This activity provides instructions for learners to create models of the Earth and then to model a "day" on Earth as well as modeling the seasons.
Pea Brain!: Explorations in Estimation
Source Institutions
In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.
Portable Potable Pressure
Source Institutions
In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.
Inflate-a-mole
Source Institutions
In this activity, learners conduct an experiment to find the volume of one mole of gas. Learners capture sublimated gas from dry ice in a ziploc bag and use water displacement to measure its volume.
How Small Can You Cut?
Source Institutions
In this lesson, learners cut paper into very small pieces to explore the small size of quarks, the smallest thing we know of on Earth.
Energy Use in the Americas
Source Institutions
Learners explore the relationship between energy consumption, population, and carbon emissions in the countries of the Americas.
Ramps 2: Ramp Builder
Source Institutions
In this inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together.
Mass of the Earth
Source Institutions
In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.
Scientific Measurement Exercise
Source Institutions
Learners measure irregularly shaped bones using a variety of measurement methods and tools. Then, they measure again using standard conventions and metric tape measures.
Making Rivers
Source Institutions
In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.
Great Steamboat Race
Source Institutions
In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.
Dinosaur Flesh and Bones
Source Institutions
In this activity, learners explore dinosaur skeletons.
Compare Dinosaur Body Parts
Source Institutions
In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most to learn about the different sizes of dinosaurs.
Algebra: Aw Chute!
Source Institutions
In this math lesson, learners determine and compare the rate of descent of various learner-constructed parachutes. Learners construct parachutes that will have maximum hang times.
A System of Transport
Source Institutions
In this activity about the human heart (on page 5 of the PDF), learners work in teams to simulate the volume of blood moved through the circulatory system by transferring liquid into--and through--a s
Sharks: Taking a Bite Out of The Myth
Source Institutions
In this activity, learners will explore trends in shark populations using shark landing data from the National Marine Fisheries Service.
Patterns and Functions: Fill 'er Up
Source Institutions
In this math lesson, learners predict, interpret, and sketch graphs of functions related to the shapes of bottles. A measure of water is poured into a container.
