In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

In this activity exploring liquid dynamics, learners design and build a clay channel in a tray of water and then see what happens when food coloring and liquid soap are added to the mix.

In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

Did you know that some breakfast cereals are fortified with ferric phosphate, while others contain tiny pieces of reduced iron?

In this activity, learners experiment and collect data during a simulation of the fluid shifts experienced by astronauts' bodies in microgravity.

"Exploring the Universe: Filtered Light" demonstrates how scientists can use telescopes and other tools to capture and filter different energies of light to study the universe.

In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

In this activity about magnetism (page 17 of the pdf), learners experiment with magnets, exploring the concept of diamagnetic materials by seeing how a grape reacts to a magnetic field.

In this optics activity, learners use paint thinner to make a small jar seem to disappear inside a larger jar.

Learners observe an electrochemical cell constructed from a small jar containing zinc and copper strips immersed in separate solutions. The strips are connected to a motor that turns a small fan.

In this activity, learners follow a recipe to make hollandaise sauce. Learners discover how cooks use egg yolks to blend oil and water together into a smooth mix.

In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.

In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.

This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.

In this activity, learners will create beautiful greeting cards by marbling with shaving cream and food dye. They will explore the chemistry behind the art of marbling.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

This is a perfect summertime lunch activity! Pico Cricket is required (micro controller). First, get a bunch of cut up fruit, line them up, then plug a piece of fruit with a Pico Cricket sensor clip.

This is a quick, yet dramatic activity/demonstration that introduces learners to the concept of energy transfer. A small ball is placed on top of a large ball and both are dropped together.

This is written as a display, but can easily be adapted to a hands-on activity. Learners discover how all the parts of a diaper work together to keep babies dry and comfortable.
