This mirror-tracing activity related to proprioception is a visual and motor test that involves learning a new motor skill.

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 examine their tongue and taste buds.

In this activity, learners stain fabrics--on purpose!

In this activity, learners model estuaries, artificially enriching both fresh and salt water samples with different amounts of nutrients and observing the growth of algae over several weeks.

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

In this activity (page 26 of the PDF), learners make observations, formulate hypotheses and design a controlled experiment, based on the reaction of carbon dioxide with calcium hydroxide.

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 math activity related to light, learners explore why a light, such as a candle or a streetlight, looks dimmer the farther away from it we get.

Learners draw and describe a leaf, and then re-find leaves drawn and described by other learners. Learners can observe leaves outside, or leaves may be brought into the classroom.

This activity helps the learner answer the question: "What environmental problems arise due to animal and human overpopulation and what might need to be done to combat these problems?" Learners play a

In this investigation, learners gather information on various food items during a field trip to a local grocery store.

In this activity, learners are divided into teams.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

In this activity (pages 5-7), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

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.

In this activity, learners identify different classes of matter based on physical properties.

In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.

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.

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.
