In this activity, learners make "totally tubular" forms of carbon. Learners use chicken wire to build macro models of carbon nanotubes.

In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.

In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

In this activity, learners investigate passive solar building design with a focus solely on heating.

In this activity, learners build a scale model of the solar system using a roll of toilet paper.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

In this activity, learners will explore the dynamics of air pressure by using a candle, a cup, and a dish of water.

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

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

In this activity, learners explore how boats are engineered to achieve speed.

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.

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.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

In this activity, learners create models of ionic compounds and observe the chemical formula of binary molecules they have created.

In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

Using simple, inexpensive items, learners build and test submarine models.

In this activity, learners will explore engineering concepts to construct a blanket fort using materials sourced from home.

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.
