Introduction to Matter
Begin your states of matter lessons with a demonstration designed to introduce the concept that all matter has properties. Reinforce this concept through vocabulary exploration, and the creation of atom models; salt, water, and carbon...

States of Matter
Solids, liquids, gasses oh my! Young scientists will be amazed when they try this experiment, which uses dry ice to discover the states of matter through sublimation.

Mysterious M&M's
The first in a six-lesson plan 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...

Density
Explore the concept of density within states of matter—gases, liquids, and solids—through a group experiment in which young scientists test objects' texture, color, weight, size, and ability to sink or float.
American Chemical Society
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...

From Gas to Liquid to Solid
From gas to liquid condensation to solid frost, water undergoes phase changes before young scholars' 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...

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...

Properties of Balls
Enhance your states of matter lessons with a hands-on science investigation that compares six different balls' color, texture, size, weight, ability to bounce, and buoyancy.
American Chemical Society
Investigating the Line
Note that this lesson is best paired with the preceding lesson in the unit. In that lesson, elementary physical scientists observed that the color coating of M&Ms® candies do not mix when dissolved off of the chocolate surface. Now...

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...

Water in the Geosphere
Through a PowerPoint presentation and the embedded animation and video, earth science enthusiasts find out about the moisture in the soil beneath our feet. In the animation, follow a water molecule on its path through the water cycle. As...

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...
American Chemical Society
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...
PBS
Breaking it Down
After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...
American Chemical Society
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...
American Chemical Society
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...

A Hilly Ride
Different types of energy are the focus of this science resource. Learners identify situations in which kinetic and potential energy are exchanged. They conduct an in-class inquiry which leads them to discover that there is a limit to...
American Chemical Society
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...

Lego Molecules
Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, young scholars build molecules based on the chemical formulas of common compounds.
American Chemical Society
Racing M&M Colors
More than anything, this is great practice in scientific inquiry. After discovering that the color coating of an M&M® dissolves in water during a preceding activity, investigators now question whether or not the color makes a...

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.

What Do You SUBpose?
Submarines are the fous of this math and science lesson plan. In it, learners explore the world of submarines: how they work, and what they are used for. They engage in hands-on activities, watch video clips, and work in cooperative...

What is the Water Cycle? Activity A
Hydrologists create a concept map about how water is used and a sentence strip defining water and describing its unique properties. Small groups work together to fill a small milk carton and compute the mass of water inside. The next...

Water in the Atmosphere
A slide show serves as the backdrop for a lesson on the moisture in Earth's atmosphere. Through it, mini meteorologists learn about the attributes of the atmosphere and actually use data-collecting weather tools to make observations and...
