Using toothpicks, straws, or tubes of rolled up newspaper, learners create 3-dimensional models to illustrate the basic structure and function of the cell membrane, and place an object inside to repre

This series of chemistry stations is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Each of the six stations features either a chemical or p

This is a perfect summertime lunch activity! Pico Cricket is required (micro controller). First, get a bunch of cut up fruit, line them up, then plug a piece of fruit with a Pico Cricket sensor clip.

In this simulation of synapses, learners act out communication at the neural level by behaving as pre-synaptic vesicles, neurotransmitters, post-synaptic receptors, secondary messengers and re-uptake

In this activity, learners explore the "nuts and bolts" of gene chips.

In this genetics activity, learners create and decode a “DNA recipe” for a dog by randomly selecting strips of paper that represent DNA.

In this activity, learners model, on a human-sized board game, how changes in water temperature may affect fish distributions and, ultimately, fisheries.

In this activity, learners construct their own spectroscope as they explore and observe spectra from familiar light sources.

This exercise can be used to stimulate the investigative nature of learners as they use forensic plant pathology techniques to prove the learners' innocence in a mock murder investigation.

In this activity, learners receive a labeled plastic film canister containing a material representing a pollutant (i.e. pencil shavings = a beaver's wood chips).

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

This board game teaches learners about energy decision making. Players select cards that determine the transportation and home design that will influence their expenses as they play.

In this activity (on pages 55-66 of PDF), learners fold paper into origami shapes and then combine several identical shapes into a three-dimensional structure.

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

By participating in a seed scavenger hunt, learners examine many adaptations of seeds, including how many seeds a plant makes, how those seeds travel to new locations, and what protects them from pred

To convey the concept of how animals adapt to survive, this game asks learners to imagine what adaptations a given animal would need to live in a certain environment—including environments where such

In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

In this outdoor activity, learners go "can fishing" and discover the kinds of aquatic organisms that live in and on submerged cans.
