Change in Temperature - Exothermic Reaction
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...

From Gas to Liquid to Solid
From gas to liquid condensation to solid frost, water undergoes phase changes before students' eyes! Using ice, salt, water, and a metal can, they set up an investigation that can be used in a physical science setting, or as part of a...

Condensation
It's time to break the ice! If you are doing all of the lessons in the unit, children have already seen that increasing heat increases the rate of evaporation, but is the opposite true? Does decreasing temperature cause more condensation...

Evaporation
This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag and...

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...

Exploring Moisture on the Outside of a Cold Cup
As a stand-alone or as part of the intended unit, this is a valid investigation of what causes condensation to occur. By limiting the amount of air around a cold cup of water and comparing it to one out in the open, they find that the...

Matter on the Move
Start this mini unit on matter out by demonstrating how food coloring behaves when placed in cold and in hot water. Then have the class experiment with warm water and soap film. Pupils will learn that an increase in thermal energy also...

Changing the Density of an Object - Changing Shape
Continuing with the concept of volume and its effect on density, learners now work with a piece of clay to see if they can get it to float in water. This is a memorable end to a seven-part investigation of density. Make sure to check out...

Curious Crystals
Crystals are more than meets the eye! Can learners tell them apart simply by observation? As they examine five samples with a magnifier, they find that appearance alone is not enough. This serves as an introduction to a mini unit on...

Using the Combining Test to Identify Unknown Liquids
Once investigators have learned how their mystery liquids interact with water during the preceding activity, they now use their observations to identify them. This is an ideal conclusion to the mini unit on the properties of water.
American Chemical Society
Using Color to See How Liquids Combine
Blue-tinted water is added to unknown liquids that have been tinted yellow to find out how they interact. This is a memorable activity that is part of an investigation on the properties of liquids, which is part of a unit on the...

Usage of words "Care", "Matter", and "Mind"
In this correct usage worksheet, learners use context clues to select the correct word for each sentence, either "care", "matter" or "mind", to give the proper meaning.

Crushing Test
Solidify understanding of the properties of crystals by crushing them to compare hardness. After some class discussion, a procedure is planned, and then small groups go about making observations as they crush five different crystal...

Colors Collide or Combine?
As part of a unit investigating the dissolving of M&Ms® candy coating, this lesson examines whether or not the different colors combine. There are no new concepts revealed in this particular lesson, but learners will see that the...

Past School Practices
Learners research the history of a school system. In this school system lesson, students list the grade levels and subjects taught in their school and interview their teachers and administrators. Learners collect past photographs of...

Rocket Me into Space
Students engage in a lesson that reinforces rockets as a vehicle that helps us explore outside the Earth's atmosphere by using the principles of Newton's third law of motion. Also, the principles that engineers deal with when building a...

Toboggan Science
Young scholars conduct toboggan time trials to investigate the variables that have the greatest effect on toboggan speed. In small groups, they develop a hypothesis to test and perform three trials on the toboggan run for each variable.
