Molecules And Temperature

Students observe the motion of water molecules using food coloring. In this molecule movement lesson plan, students observe motion in hot, cold and room temperature colored water and record observation data on record sheets. Then write a...

Molecules to the Max! refers to a movie released in 2009 about the world of atoms and molecules. A helpful discovery guide provides five posters on science topics typically covered at the middle school level. It also explains the...

Exactly what do groundhogs know about weather? Not as much as your science students will after completing these lessons and activities that cover everything from the earth's rotation and the creation of shadows, to cloud...

Alone, or as part of the intended unit on chemical reactions, this activity allows learners to experience an exothermic reaction. Here, learners add calcium chloride to a baking soda solution and watch the temperature rise! They will...

Gain insight into how scientists group materials based on their properties, such as conductibility and malleability, with this informative and engaging video. First, molecules, atoms, substances, and elements are reviewed, then...

What a terrific way to explore temperature! Little scientists can use this resource to make their own large thermometer and measure hot and cold liquids. They can then come up with their own experiment ideas or discuss how it might be...

Weather watchers are introduced to temperature scales using step-by-step animated slides. The Home set explains the Fahrenheit scale on a thermometer, while the Watch Out! set introduces Celsius. A Try It! tab contains two guided...

Students experiment with common substances to observe molecular behavior. In this molecular properties lesson, students move through four stations as they try to inflate a balloon inside a bottle, pour water from a jar, and observe how...

Middle school chemists visit interactive websites in order to discover what happens to molecular motion when heat is added to matter. They conduct an experiment that demonstrates the expansion of matter with the addition of heat. A lab...

Students describe and compare the layers of the atmosphere. They explain how to measure the temperature of the atmosphere. They also explain what causes the atmosphere to heat up in some places more than in others.
