The Law of Conservation of Matter
The Law of Conservation of Matter can be complex for young scientists to fully grasp. Use this experiment to help simplify the process as pupils perform two experiments to determine mass: one that melts a substance and the other that...

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...

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...
Curated OER
Matter In Motion
In this science worksheet, students find the definitions to basic terms related to beginning the study of physics and then complete the riddles on page 2.

Physical and Chemical Changes
Young scholars examine the different changes in matter. In this chemical change lesson students determine the amount of reactant made in a reaction using the law of conservation.

Classifying Matter
Second graders conduct investigations to explore matter. In this states of matter activity, 2nd graders complete four activities to analyze the three states of matter. Students analyze the properties of solids, liquids, and gases....

Physical/Chemical Properties of a Burning Candle
Students investigate the physical and chemical properties of a candle before and after it is lit. They conduct a burning candle experiment, and complete a KWL chart and worksheet, recording the results of the investigation.

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 boil water through...

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.

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...

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...

Mysterious M&M's
The first in a six-lesson mini unit, all using M&Ms® candies, this physical science activity gets kids to observe a single piece and discover what happens when it is placed in a plate of water. The activity can be used to introduce...
Curated OER
Solids, Liquids and Gases
Students are introduced to the various states of matter. After watching a video, they discover how to compare the three states using its shape and volume. In groups, they participate in an experiment with solids, liquids and gases and...
Curated OER
Edible Transformations
Students 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.

Physical And Chemical Changes
Second graders identify physical and chemical changes of matter. They distinguish between physical and chemical changes. They classify changes as physical or chemical.

Investigating the Line
Note that this activity is best paired with the preceding activity in the unit. In that activity, elementary physical scientists observed that the color coating of M&Ms® candies do not mix when dissolved off of the chocolate surface....

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...

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...

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...

Solubility Test
Make sure to consult the teacher's handbook, Inquiry in Action - Investigating Matter Through Inquiry, for two demonstrations that can be done to introduce solubility and measuring crystal mass before having the class conduct this...

Amounts of Dissolved Oxygen in Various Bodies of Water
Young scholars test water to determine the dissolved oxygen content while displaying the proper use of testing instruments while visiting water testing sites. They determine if the amount of dissolved oxygen is appropriate for the tested...
