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 activity, learners explore how to protect their skin while applying pesticides to plants.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

In this activity, learners discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.

In this activity, pairs of learners model how scientists use craters to determine the ages of lunar surfaces. One partner keeps time while the other creates a painting for the other to interpret.

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

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

Learners experiment to see which colors of light will cause a phosphorescent (glow-in-the-dark) material to glow.

Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.

In this activity, learners create volcanoes like those they have examined on Earth and Mars through images taken by spacecraft.

This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

This activity introduces learners to the structure and properties of carbon nanotubes.

In this activity, learners help create and then navigate an outdoor course of the traditional "planets" (including dwarf planet Pluto), which are represented by small common objects.

In this activity, learners make self-assembled polymer spheres.

In this game, learners explore the different sizes of things in the world. In this Twister-like game, learners must place a hand or foot on a circle of the right scale - macro, micro, or nano.

In this activity about electricity, learners identify closed and open circuits. First, learners examine and label diagrams of open and closed circuits.
