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...

Let It Snow! Let It Melt!
Winter weather offers a great opportunity to teach young scientists about the states of matter. This activity-based lesson includes a range of learning experiences, from experimenting with the rate at which ice melts...

Ice Cream Special
We all scream for ice cream! Individuals create home-made ice cream in the classroom. This is a delicious way to show a real-world application of the freezing point depression to your class.
Resources for Educators
Fractions of Fun
Reinforce concepts and encourage learner engagement with a collection of math games, science experiments, and cross curricular activities. In one fun resource, learners sort objects, keep a diary of everyday fractions, play a game using...

States of Matter
Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

Water – Changing States (Part 2)
Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...
Curated OER
Thermal Expansion and Sea Level Rise
Placing a thermometer and a glass tube into a flask of cold water and sealing it, you can expose it to heat and very visually demonstrate thermal expansion to your earth science class. Follow it with a discussion about how the increasing...

Polygons, Pingos, and Themokarst! Oh MY!
Students complete activities to learn about the common land features in Alaska. In this land study lesson, students study an overhead for permafrost features. Students define ice wedge polygons, thermokarst, and pingos. Students also...

Climate Change: What's Hot? What's Happening?
Students conduct a web-based project to analyze recent or on-going climate change research in the North. They are exposed to the application of science in current research on climate change.

Ice Ain't Easy
Students are introduced to the laws of thermodynamics. The 1st law of thermodynamics states that the energy must be conserved when two objects of different temperatures come in contact. If one object gains energy, the other object must...

Salt Water vs. Fresh Water
Students explore why the oceans do not freeze. They explain why they think the Atlantic Ocean does not freeze. Students are given background information about what they are doing. They create a hypothesis about what they believe...

Energy Conservation
Third graders discuss four points related to conservation. They work in groups to design a package to keep an ice cube from melting to demonstrate the concept of insulation. They then make a chart that shows which materials used did the...
Normal Community High School
Density
Change the density of water by adding minerals. The presentation discusses density—from the definition to calculations—and applies it to the real world. It briefly mentions specific gravity, and finishes by showing Archimedes'...

More on Conduction and Convection
Why do some items feel colder when they are the same temperature? How should you keep your soda cold? What makes the wind blow? These are just some of the things middle schoolers discover when completing a lesson on...
California Academy of Science
Climate Change Impacts
Getting kids thinking about climate change now, will hopefully push them into action when they become adults. Young environmentalists discuss the evidence and causes of climate change seen in the state of California. They brainstorm ways...

What's the Matter? Where Did it Go?
Eighth graders analyze questions posted on a large poster in the room and work in groups to record their response to the question on paper, rotating to the next question after two minutes have passed. They review the characteristics of...
