In this activity, learners work in teams build and launch rubberband-powered foam rockets.

Learners work in groups to design and build a tower out of balsa wood. As a motivator, they can compete to build a tower with the highest strength-to-weight ratio.

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 (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

In this activity, learners build their own construction cranes using tongue depressors and pushpins.

In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit

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.

In this activity, learners identify the DNA base bars guanine, cytosine, thymine and adenine. Learners create a DNA model using colored paper clips to resemble these base pairs.

In this ecology activity, learners make a model water-based ecosystem called a terraqua column. The column (in a large soda bottle) includes pond water, duckweed, sand or gravel, and small snails.

Learners will construct a model of a heart valve using a film canister, a piece of masking tape, and a piece of paper.

Learners explore the field of civil engineering by making a bridge using spaghetti as their primary building material.

In this activity, learners model how the Moon's volcanic period reshaped its earlier features.

This activity introduces learners to the structure and properties of carbon nanotubes.

In this multi-station lab, learners conduct a series of experiments to explore the processes and effects of weathering and erosion.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this math lesson, learners design an experiment to model a leaky faucet and determine the amount of water wasted due to the leak.

In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.

In this activity, learners string a line across the room and build cable cars that can move from on end to the other.

In this activity, learners take on the role of various parts of the cell in order to model the process of protein synthesis.
