This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

In this optics activity, learners conduct an experiment to find out why two eyes are better than one!

In this activity, young learners use their sense of touch rather than sight to identify a mystery object in a bag. Learners take turns acting as "peekers" and "sensers" throughout the game.

This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

In this activity (15th activity on the page) about the sense of touch, learners use glue and cardboard to construct a maze they use with their eyes closed.

In this activity (9th activity on the page), learners work in pairs to see how their perception of touch differs from reality.

This is an educator-led demonstration of microarray technology using a model created from a pizza box and ping-pong balls.

In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.

In this activity, learners investigate different types of bird beaks using household items which mimic different beak examples.

In this neuroscience activity (4th activity on the page), learners make their own set of Von Frey hairs to test detection thresholds.

In this genetics activity, learners discover how to extract DNA from green split peas.

In this activity (10th activity on the page) about the sense of touch, learners make Braille letters out of cork or cardboard and map pins.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

In this activity, learners create a model of a neuron by using colored clay or play dough. Learners use diagrams to build the model and then label the parts on a piece of paper.

This is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.

In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

In this activity, learners take their own pulse and explore how heart rate is affected by various activities.

In this optics activity, learners conduct an experiment to explore peripheral vision. Learners collect data about their ability to see shapes, colors, or letters using their peripheral vision.

In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw

This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.
