In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.

In this activity (page 1 of the PDF under SciGirls Activity: Dinosaurs), learners will model how paleontologists estimate the age of fossil discoveries by extracting “fossil” playing cards from newspa

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

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

In this "gross" activity (on pages 34-46), learners make a life-size model of a human digestive tract, and follow the life of a beef tapeworm as it makes its way through.

In this fun snack and craft activity, young learners make "Ants on a Log" and their own model of an insect. The purpose is to learn the three main insect body parts—head, thorax and abdomen.

In this activity, learners review and discuss weathering, erosion and mass wasting, to gain a stronger understanding of how Hickory Run’s Boulder Field was formed after the Laurentide Continental Glac

In this three-part activity, learners explore how waves are formed and why some waves are bigger than others. First, learners observe waves of water in a pan generated by an electric fan.

In this activity (page 87 of the PDF), learners move their bodies to better understand the three axes of rotation: pitch, roll and yaw.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "Dinosaurs, Dinosaurs" by Byron Barton to understand some background information about dinosaurs.

In this activity, learners plan and create a 24-foot long, two-dimensional model of our solar system, and compare and contrast the differences between planets and the sun.

Discover how a refracting telescope works by making one from scratch using common items. This telescope won't have a tube so the learner can see how an image is formed inside the telescope.

This neuroscience activity introduces learners to how messages are sent and received by neurons. Learners use modeling clay and pipe cleaners to build model neurons.

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

In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.

In this earth science activity (page 14 of the PDF), learners use layers of closed-cell foam to create their own model of the mid-ocean ridge in order to simulate seafloor spreading.

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

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

In this activity, learners use edible models of the DNA molecule to transcribe an mRNA sequence, and then translate it into a protein.
