Straining Out the Dirt
Learners take on the role of environmental engineers as they design water filters.
Modeling Limits to Cell Size
Source Institutions
This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.
Understanding Albedo
Source Institutions
In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper
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.
Paper Drop Design Competition
Source Institutions
Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.
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.
Column Chromatography
Source Institutions
In this activity, learners separate the components of Gatorade using a home-made affinity column.
Build a Borneo Glider
Source Institutions
In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So
Modeling Tidal Action
Source Institutions
In this activity (Lesson 1), learners work in groups to create tide simulations.
Rocket Wind Tunnel
Source Institutions
In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.
Simple Submarine
Source Institutions
Using simple, inexpensive items, learners build and test submarine models.
How Greenhouse Gases Absorb Heat
Source Institutions
Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.
Airplane Wing Investigation
Source Institutions
This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.
Make a Comet Model and Eat It!
Source Institutions
In this activity, learners build models of comets, using edible materials, to learn about comets' structure.
3...2...1 Puff!
Source Institutions
In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.
Investigating Convection
Source Institutions
This experiment is designed to illustrate how fluids, including water, have the ability to flow.
Building a 3-D Space Maze: Escher Staircase
Source Institutions
In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about
Exploring the Nanoworld with LEGO Bricks: Structures and Their Construction at the Nanoscale
Source Institutions
In this activity (pages 42-49), learners discover the methods and challenges of building nanoscale structures with macroscale equipment.
Build A Hydrometer
Source Institutions
In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.
Drip, Drop, Drip, Drop
Source Institutions
In this math lesson, learners design an experiment to model a leaky faucet and determine the amount of water wasted due to the leak.
