Using pipe cleaners, straws, and beads, learners explore the building blocks of life by creating their own model of DNA.

In this hands-on botany activity, learners sprout vegetables in film canisters.

In this activity (on page 134 of the PDF), learners explore reaction time.

In this yummy biology activity (page 3 of the PDF), learners participate in a demonstration of natural selection.

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

In this activity, learners pretend that they are orcas and search for their "pods" using Morse code.

In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

In this activity, learners explore dinosaur skeletons, anatomy, and locomotion. Learners compare and contrast dinosaur skeletons and drawings.

In this quick optics activity, learners use a dim point of light (a disassembled Mini MagLite and dowel set-up) to cast a shadow of the blood supply in their retina onto the retina itself.

In this health activity (page 3 of the PDF), learners will discover why covering their mouth and nose while sneezing is so important.

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

After learning that some of the chemicals we add to food crops may have harmful consequences on our health and the health of the environment, learners will create a pocket-sized card with their favori

This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

In this simulation, learners model two elephant seal populations and how they change over time. Learners start with cards representing a variety of seals.
