This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

In this activity (17th on the page), learners investigate why you cannot see colors in dim light.

In this demonstration (18th on the page), learners conduct a simple test to explore how the cornea refracts light, which is further bent by the eye lens through a process known as accommodation.

In this activity, early learners create paintings by making music and rhythm. Learners place paper in cans, add paint-soaked beans (or pebbles) and put the tops on.

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

Capture soap bubble patterns on paper! In this activity, learners can create beautiful pictures from popping soap bubbles.

In this activity (pages 32-41), learners learn how the atomic and molecular arrangement of matter are related to physical properties.

In this design challenge activity, learners add headphones to a previously built instrument (see "Build a Band" activity) to make it easier to hear.

In this optics activity, learners explore interference by adding wax blocks to a ripple tank.

In this activity, learners observe, explore and investigate vibrating instruments in everyday places and create music in unique ways.

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this activity, learners create a straw oboe to explore sound and pitch.

In this simple chemistry activity (page 1 of PDF under SciGirls Activity: Colorblind Dogs) about acids and bases, learners will mix a baking soda and water solution and use it to paint a message on a

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners will explore light and rainbows with this easy setup! Learners will only need a cup of water, some paper and a flashlight.

In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.

In this activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.
