In this physics activity (page 6 of the PDF), learners will build a class 1 lever and hypothesize and test the distances two objects need to be placed from the fulcrum in order to balance.

In this physics activity (page 6 of the PDF), learners will try to keep a marble in a bottomless cup without touching the marble inside.

In this biology activity (page 8 of the PDF), learners will explore how saliva assists in the beginning of the digestive process.

In this chemistry activity (page 5 of the PDF), learners will use milk and a few other basic ingredients to create a chemical change to make a color wheel.

In this chemistry activity which should only be done under adult supervision (page 10 of the PDF), learners will create an exothermic process by making Sodium Acetate.

In this classification activity, learners will learn one way of organizing plants and animals.

In this amazingly simple physics activity (page 5 of the PDF), learners will explore how exerting a force on an object can give it kinetic energy and momentum.

In this physics activity (page 3 of the PDF), learners will move a load using a lever of each of the 3 classes. They will explore the differences between these classes and which are more effective.

In this chemistry activity (page 8 of the PDF), learners will identify the instances of physical change, chemical change, and solutions while making homemade soda pop.

In this physics activity (page 8-9 of the PDF), learners will explore wind energy. They will build their own windmill and see how energy from wind can be converted into a useable form.
