In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

This is a classic exercise for visualizing the scale of the Solar System.

In this activity, learners confront their perceptions of gravity in the solar system.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this space science activity, learners work together to create a human-powered orrery to model the movements of the four inner planets.

In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.

In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.

Based of the The Tech Challenge 2015, learners will engage in two mini-design challenges related to seismic engineering.

Demonstrate the Bernoulli Principle using simple materials on a small or large scale.

Learners build a model of a pollution control device--a cyclone. A cyclone works by whirling the polluted air in a circle and accumulating particles on the edges of the container.

Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

In this demonstration, learners observe vinegar and baking soda creating carbon dioxide (CO2) in a bottle. The gas is poured out of a bottle onto a candle flame, putting out the candle.

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.
