More Thermochemistry Problems
This two-page assignment covers basic thermochemistry concepts. Chemistry learners identify exothermic and endothermic processes, explain a phase change graph, and draw an energy level diagram. There are no problems to solve, just...

Specific Heat and Latent Heat in Condensation
There's more to melting than meets the eye! Junior physical chemists investigate the differences between specific and latent heats as a substance undergoes a phase change. Users remove heat from the system and observe changes in kinetic...

Heating Curve
Wow! This is a nifty presentation for teaching high school chemists about the heating curve. It displays a graph for temperature vs. heat added, then enters the curve itself. The final slide identifies each part of the curve. Notes are...

Water and Ice
Students make observations of ice as it melts. In this phase change lesson plan, students observe ice as it melts in a cup. They discuss their observations and place the cup of water into a freezer to change it back into ice.

Exploring Moisture on the Outside of a Cold Cup: For Dry Environments
If the area you live in is arid, or the preceding experiment in this unit didn't yield obvious results, use this one in place of it to help reveal where condensation comes from. The mini unit that this is part of a comprehensive...

Moon Phase Mania
Now you see it, now you don't. Our moon seems to pull a disappearing act from time to time—but why? Take your seventh grade scientists above and beyond to discover the truth about the moon and the role it plays in Earth's little...

Changes in Ecosystems
How does water pollution affect the environment? Provide your class with the resources to answer this question as they learn about eutrophication and ecosystem changes. Over two weeks, they simulate the effects of pollution on the...

Phases of Life Poster Project
Now this is a clever approach to familiarizing aspiring astronomers with the phases of the moon! They first record the specific dates for ten special events in their lives. Then they use an online moon phase calendar to find out which...

BioFuels: The Chemistry and Economics of Alternative Fuels
Junior chemists manufacture biodiesel in the lab. In this exercise, they check the purity of the biodiesel using thin layer chromatography. They also calculate its density and heat of combustion. They are sure to rise to the...

Edible Transformations
Learners differentiate the different phases of matter. For this chemistry lesson, students conduct several hands-on exercises to discover how matter transforms when mixed together. They identify the different stages in the water cycle.

Earthquakes
Students observe the melting of ice. In this phase change instructional activity, students observe ice as it melts. They discuss the process and create a Venn diagram comparing water and ice.

Chemquest: Physical Changes or Chemical Reactions
Students explore physical and chemical changes. For this chemistry lesson plan, students will go outside to observe changes seen in nature. Students will then work in the lab to identify changes at different stations prior to doing a...

Water Cycle
Be water wise! Science scholars learn the water cycle on a global scale in part seven of a 13-installment series. The hands-on interactive allows them to explore Earth's water storage, types of precipitation, and the cycling of water...

Moon Phases
Sixth graders investigate the phases of the moon. In this moon phase instructional activity, 6th graders discover that the moon changes in a cycle as it orbits Earth. Students label pictures of moon phases and keep a moon phase...

Nothing New? A Physical Change
Fifth graders discuss the differences between chemical and physical changes.  In groups, they complete experiments and discover how a physical chnage can be reversed.  To end the lesson, they review the steps of the water cycle and...

Phases of the Moon
Students read "The Moon Seems to Change" and conduct an experiment with oranges to demonstrate the phases of the moon. They write about the experiment and describe each phase of the moon.

Exploring Phases of Matter
Students discuss and experiment with the phases of water.  In this phases of matter lesson, students recognize the different states of matter.  Students measure and record changes and understand when the state changes.

States of Matter Lesson
Second graders identify the three phases of matter and demonstrate how a property can change states of matter. In this states of matter activity, 2nd graders make an Ooze to discover how a solid changes into a liquid. Students...

Phases of the Moon
Students research and identify the phases of the moon. They consider the moon's rotation, as well as that of the earth and sun. They write a description of their research and present it to the class.

Phases of the moon
Third graders name the phases of the moon. In this moon phase lesson, 3rd graders listen to the story The Moon Seems to Change and they discuss the different moon phases. They take oreos and split them apart and look at the cream to see...
