Science 4 Inquiry
States and Phases of Matter
Plasma is the most common phase of matter in our universe. Scholars explore the change of energy as molecules change phases of matter. They rotate through stations, graphing the changes in energy level.

Changing State: Melting
Dry ice is extremely cold — it is -109.3°F or -78.5°C. Scholars observe and explain the molecular motion associated with melting. Then they design their own experiments to speed up the melting process. Finally, a teacher presents a...

Phase Changes of Water
A micro-unit on the phase changes of water includes three laboratory activities. Junior scientists compare the densities of ice and water, and then they do the same for cold and warm water. They examine freezing and boiling temperatures....

Fluids
In 1879, Sir William Crookes discovered the fourth state of matter, plasma. The presentation covers states of matter, phase changes, density, pressure Pascal's Principle, buoyant force, Archimedes' Principle, Bernoulli's Principle,...

States of Matter: Solid, Liquid, and Gas
Solid, liquid, and gas: they all matter. Scholars create an animation of the various states of matter, experiment with the temperature of water as it changes states, and observe carbon dioxide as it changes states. The lesson also...

Sublime Sublimation
Dry ice isn't dehydrated water, and young scientists learn why in this fascinating presentation. After watching a video, they complete three different activities using dry ice. Upon completion, they discuss the scientific principle.

Capturing Carbon Dioxide
Why don't we just capture carbon dioxide in the air and store it somewhere else? A hands-on lesson allows scholars to explore a complex concept. First, they will create a carbonated beverage, and then they will determine if liquid...

Bubble Suspension
Create a cushion of carbon dioxide gas to float some soap bubbles on. Many concepts can be demonstrated through this activity:
Carbon dioxide gas is more dense than air
Bubbles are semipermeable, allowing only carbon dioxide to diffuse...

Investigating the Climate System: Energy, A Balancing Act
Earth science explorers design an experiment to demonstrate that the albedo of a surface affects its temperature. They test to find out if moisture on the surface affects temperature. They discover whether or not concrete or asphalt heat...
