In this astronomy activity, learners create a model of the solar system using beads and string.

Everybody loves boomerangs! In this activity about force and motion, the learners will experiment with boomerangs and explore how they work. This is a great activity to get learners up and moving.

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

In this physics activity, learners experiment with soap bubbles to see what variables affect their size. They explore how soap film and bubbles always seek the smallest surface area possible.

In this activity about color, learners get to explore the process of chromatography. Right before their eyes, they can watch ordinary green and black ink turn into a literal rainbow of colors.

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 geology activity (page 6 of the PDF), learners explore how carbonic acid can slowly dissolve limestone and form caves.

In this forensics activity, students will explore the methods that investigators use to confirm the authenticity of handwriting.

In this environmental science activity (page 4 of the PDF), learners use vinegar and chalk to observe the effect of acid rain on various building materials and plant life.

In this geology activity, learners use a microscope to discover and identify the components of sand.

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 physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

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.
