In this activity, your students will engage in the practice of alchemy by guiding a penny through a series of physical transformations that give it a gold-colored appearance. They will then be challenged to determine whether the penny is truly gold.

Students use Archimedes Blocks and density calculations to connect visual and numerical representations of fractions.

Access to a water supply is also required.

Students use light boxes to explore the effects lenses and mirrors have on the path of light. They then consider the human eye and what it means to be near- or far-sighted.

This investigation requires access to power outlets.

A student favorite and beloved tradition in many schools! Students apply their knowledge of experimental design to draw conclusions about the effects launch angle and launch velocity have on the horizontal range of a rocket.

This investigation requires the use of a large open field with an access point for the van.

Get your students on their feet in the name of science! Students are challenged to match a given position-time graph by moving in front of a motion detector and develop their understanding of graphical representations of motion. 

This investigation requires access to a power outlet.

Spark timers and toy cars are used to spark student ideas about uniform motion and make connections between physical motion and graphical representation!

This investigation requires basic familiarity with graphical representations of data and access to power outlets.

Students use a simple model to consider what happens during an oil spill, making predictions, observations and explanations. Students are surprised by how the oil and water will not mix, however hard they try!

This investigation requires access to a water supply.

What does the inside of a hurricane look like? Students unpack this question using a tank model and all its stormy patterns.

This investigation requires access to a water supply and a power outlet. 

Students consider density in the context of ocean flows as they make predictions and then test their ideas by creating their own density currents!

This investigation requires access to a water supply, ice, and a power outlet.

Students unpack the concept of heat by comparing how ice responds to different materials. There are plenty of surprises as the ice melts! 

This investigation requires access to ice.

Students use their senses to detect a chemical change. Watch their eyes widen as they hold a bag that changes temperature, fills with gas, and changes color. This activity is derived from the GEMS Chemical Reactions.

This investigation requires basic familiarity with chemical changes.

Physical and chemical changes are compared through a simple model of acid rain. Students get excited as they create a bubbly chemical reaction. 

This investigation requires basic familiarity with physical and chemical changes.
