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...

Gases Matter
Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Physical Changes and States of Matter - One
Third graders study the three states of matter and identify the physical changes that take place between them. There is an initial teacher-led demonstration followed by a meaningful whole-class inquiry. These two activities should lead...

As a Matter of Fact
Elementary-aged scientists discover that all matter has mass. They are shown the difference between mass and weight, and learn how to calculate mass using the appropriate tools and methods. The scientific method is used while estimating...

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...

Science: The States of Matter
Third graders conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...

Physical Changes to Matter
Pupils explore matter by conducting an in-class experiment. They experiment with water's various forms by melting and freezing water, identifying its new shape. These observations are recorded to supplement later discussion. They also...

Mixtures of Matter
Learners experiment with mixtures of matter. For this matter lesson, students investigate which liquids form a solution when mixed together and which do not. Learners also identify which solids can be separated from matter.

Observing Properties of Matter
Third graders explore matter. In this physical science lesson, 3rd graders observe several items and use their five senses to describe their properties. Students record their observations and share with the class.

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...

Physical Changes and States of Matter - Two
Here's a wonderful lesson on how substances change states. Groups of learners are given trays with a chocolate bar, a piece of paper, an ice cube, and a balloon. During the activity, the groups closely observe the changes that each...

Identifying Matter by Sound and Feel
Young scholars explore the physical properties of matter. In this matter lesson, students collaborate as they participate in an activity that requires them to identify objects using their senses of sight and touch.

Applied Science - Physics Pre-Lab
Students describe the science of physics. In this Physics lesson, students observe examples of physics within their classroom. Students create a definition for physics.

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...
Curated OER
States of Matter
Learners discuss a given set of questions based on Chemistry and matter and review a glossary of terms. They conduct experiments on each state of matter: "Dry ice and water, Dry ice and soap and Dry ice and Isopropyl Alcohol." and...
Curated OER
Heat and Matter
Students explore liquids and solids by conducting in class experiments. For this matter lesson, students define the properties of matter and how heat can change those properties. Students experiment with heating objects such as butter...

The Same, But Different Part II
Learners characterize a physical change as something that changes to a different size, but retains its basic substance. They measure volumes using milliliters, and perform an experiment that proves that gases expand when hot and contract...
Curated OER
Three States of Matter
Third graders investigate the three states of matter and the properties of materials as they undergo physical changes. They identify examples of each type of matter, role-play atoms in solids, liquids, and gases, and conduct an...
Curated OER
States of Matter
Student explore states of matter. In this science lesson plan, learners define matter, identify the states of matter, tell about the properties of each state of matter, and demonstrate an understanding of the difference between a...
Curated OER
Characteristics of Matter
Students study matter. In this science lesson plan, students examine the relationships among gravity, weight, and mass, the metric measurement of distance and volume, and density and its application to physical properties.

The Three States of Matter
Students explore the three states of matter. In this physics lesson, students are shown examples of solids, liquids, and gases. Students make cookies and identify the three states of matter during the baking process.

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...
