Students discover how rocks are created.  In this rock formation lesson, students investigate saturation, evaporation, and phase changes in geology.  Students create rock candy from skewers, string, boiling water and sugar.

Why does it look like there is a man on the moon? Why does the moon look different every night? These are the focus questions of a lesson that prompts class members to observe and record the nightly changes of Earth's natural...

Participate in three activities that look at the earth's limited water supply and the changes water goes through as it enters each phase of the water cycle. The resource is complete with three activities that demonstrate the changing...

Demonstrate the ratio of surface area to volume in your high school class by using phenolphthalein, gelatin, and an onion. Intrigue the class by leading a discussion on osmosis and diffusion, then making "scientific jello." Participants...

Fifth graders examine both physical and chemical changes, and how to identify the difference between the two. They observe the changes that occur in butter when it is exposed to heat and cold, heat energy. In their notebooks, they write...

In this chemical change worksheet, students review physical changes such as evaporation and condensation before working with chemical change. They conduct an experiment with vinegar and baking soda before recording the chemical changes...

Students explore Earth's seasons using an interactive website. In this earth science lesson plan, students watch video segments and explain Earth's seasonal milestones. They discuss the factors that causes seasonal changes.

Students illustrate the changes in the properties of a material at its glass transition point. They gather data which they use to construct graphs regarding elastic modules versus absorption modulus, tangent delta, and the effect of...

Students use a simple physical model of the Earth, sun, and moon to understand why the moon changes phases from the perspective of Earthly observers. They hold up balls representing the moon in a room with a single light source to see...

First graders discuss why the moon appears to change shape. They use flashlights and balls to simulate the sun's light shining on the moon during its different phases. They read books, paint pictures and write sentences about the moon.

Eighth graders practice using correct vocabulary and apply content knowledge related to phases of matter when answering questions about situations or observations from everyday life.

Steam engines have been around since the late 1600s, yet most pupils don't know how they work. Using an soda can, the instructor builds a simple steam engine for scholars to observe. Through a discussion, young scientists learn about the...

Second graders examine the physical characteristics of the different states of matter. In this chemistry lesson, 2nd graders observe how matter changes from one phase to another. They classify substances according to its type of matter.

High schoolers differentiate the three states of matter. In this chemistry lesson, students analyze graphs of heating and cooling curve of water. They complete a lab report and discuss results.

The learners construct a heating curve and explain its components. They perform calculations. They review phase changes and quantify Energy differences. They review phases of matter and their energy content.

Middle schoolers remove heat energy and determine how it causes a phase change.

This is actually a 10-day mini unit on thermal energy for your high school chemists. Every avenue is taken to get learners absorbed in heat: a pretest, a PowerPoint presentation, Internet exploration, demonstrations, lab activities, and...

Does it feel a little humid in here? Learners assume the role of water vapor in the atmosphere as they explore the differences between warm and cold air. They roll dice to determine their level of energy, which determines if they...

High schoolers investigate condensation in the lab. For this chemistry lesson, students explain molecular motion during phase changes. They relate this observation to Earth's weather conditions.

Fourth graders identify the characteristics of a simple physical change. They describe objects by the properties of the materials from which they are made. Students discuss the different states of matter and their distinct physical...

Cost overruns are unacceptable—in the real world and in an engaging activity. Groups of pupils get together to build a bridge out of straws, paper cups, and tape. They keep track of costs ($1,000 for each material) and must stay within a...

Introduce your classes to a fourth state of matter! Liquid crystals have a colorful sheen that changes based on different physical factors. Learners use this information to create a liquid crystal thermometer where the color of the...

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...

Astronomy is literally over your head, but this lesson will explain how we study it. Young scientists make telescopes, calculate and compare the light gathering power of lenses, and simulate detection of infared radiation....
