In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

In this biology activity (page 5 of the PDF), learners use yarn and sticky labels to build a model of a DNA strand. They discover that DNA is very long, very skinny, and packs well into cells.

In this health activity (located on page 4 of the PDF), learners will discover the importance of hand washing by observing mold growing on potatoes.

In this colorful activity (page 6 of the PDF), learners will make a multicolor density column by using different concentrations of sugar solutions.

In this fun math activity (page 5 of the pdf), learners will help a secret agent crack a case by solving math problems.

In this physics activity, learners will explore the concept of buoyancy, especially as it relates to density.

In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.

In this activity, learners will design a protective package for an egg that will allow the egg to withstand a fall without cracking.

In this activity about soil (page 7 of the PDF), learners will use their sense of touch as well as sight to understand how soil is classified based on texture and other details.

In this activity, learners will build a simple electromagnet. They will test variables that would make the electromagnet stronger.

In this yummy biology activity (page 3 of the PDF), learners participate in a demonstration of natural selection.

In this health activity (page 3 of the PDF), learners will discover why covering their mouth and nose while sneezing is so important.

In this weather activity (page 1 of the PDF), learners will construct their very own anemometer to measure wind speed.

In this physics activity, learners experiment with pulleys and find that they can decrease the effort needed when using a pulley to lift or move different loads.

This is an activity about rockets. Learners will explore how rockets leave Earth's orbit and what it takes to make a launch successful.

In this physics activity (page 8 of the PDF), learners will make their very own working compass.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this physics activity, learners will gain a better understanding of how friction, inertia, and mass affect objects.

In this chemistry activity, learners will test the pH of various foods and household substances using cabbage.

In this geology activity (page 3 of the PDF), learners simulate an earthquake with little more than an elastic band and drinking straws.
