This activity demonstrates the specificity of viral vectors for target cells in gene therapy delivery methods using two approaches: 1) STYROFOAM® models demonstrate viral ligand binding to receptor pr

In this game, learners create flash cards with an image on one side (of an animal, for example) and the sound that animal makes on the other.

In this activity, learners examine body parts (including skin, scales, and skulls) from fish, mammals and reptiles. Questions are provided to help encourage learner investigations.

In this activity, learners explore how nanosized structures can create brilliant color.

In this activity (25th on the page) about learning and memory, learners explore a training method that animal trainers employ called "shaping." Working in pairs, learners will attempt to "shape" each

In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

In this activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.

In this activity, learners observe live fish in tanks to consider how their body structures are related to their behaviors and habitats.

In this online activity, learners find out whether they are smart enough to survive as a plant.

In this activity, learners will discover what it takes to be a frog. By dressing up like one, learners can visualize how each part of the frog plays an important role in surviving its habitat.

In this online interactive, learners use fossils to infer temperatures 55 million years ago, at the sites where the fossils were found.

In this activity, learners will dissect a pumpkin or winter squash to learn the parts of the plant. This activity gets your learner hands on with every part of the plant and will be messy.

This activity has learners interacting with live crayfish, but could be adapted for a variety of similar hardy and interesting organisms.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

In this activity, learners look at and touch marine animal skulls to compare them and think about what they eat.

In this interactive activity, learners analyze seashells to explore phylogeny and evolution. Learners identify similar and dissimilar seashells to create a phylogenetic tree.

This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.

In this activity, learners will learn a bit about botany as the explore botanical names and common names of plants.

Many common household cleaners are antimicrobials.
