Super scientists visit ten stations to predict, observe, and draw conclusions about the physical and chemical changes that occur when different states of matter—liquid, solid, and gas—are placed under a variety of conditions. To...

You can't unring a bell, but can you unmelt an ice cube? Readers consider reversible and irreversible changes with a short informational reading passage and accompanying comprehension questions.

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...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Here is a worksheet that has young scientists think about things that been changed as a result of heating and cooling, and if they can be returned to their original form. There are seven scenarios to consider, and they must choose,...

To guide learners through observations of chemical samples in the lab, this resource asks them to give all formulas and complete the attached data sheet.  There are multiple questions about categories of elements and general...

Students recognize that some changes to matter are reversible and some are not.  In this matter lesson, students experiment a physical and chemical change. Students record experiment results in their science journals. Students act...

Students make ice cream as a result of viewing changes of states of matter. In this matter lesson plan, students learn how heating and cooling can effect a state of matter to change.

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...

Third graders listen to a talk on phase transitions and view three demonstrations. For this phases of matter lesson, 3rd graders complete a worksheet as they listen about phase transitions. They move through three demonstrations of phase...

The San Andreas fault is one of the longest fault zones in the world. In a series of 20 lessons, the fourth lesson plan has pupils use a paper model to recreate various types of plate faults. Each is held in position then...

Students explore liquids and solids by conducting in class experiments. In this matter lesson, students define the properties of matter and how heat can change those properties. Students experiment with heating objects such as butter and...

Graphic organizers, photos, diagrams, and text bring the world of chemical reactions to life. By viewing this presentation, young chemists learn how to recognize when a chemical reaction has occurred, and how to balance chemical...

Fifth graders investigate chemical reactions. In this physical science lesson, 5th graders make dry ice root beer and identify the type of change that occurs to the root beer mixture.

Students investigate what happens to solids and liquids when they change from one form to another. In this states of matter lesson plan, students work in groups on a virtual experiment that requires them to collect data regarding the...

Students investigate gases and liquids. In this states of matter online lesson plan, students examine how evaporation plays a part in the transition of liquids into gases as they watch a kettle of water boil and then work in small groups...

Fourth graders determine what is meant by a physical change, and they demonstrate how they can make physical changes. They complete activities at stations that entail changes in color, size, texture, hardness, or state of matter. Using...

In this phase change instructional activity, students read about the particles in substances that speed up and slow down for substances to change phases. They answer eight questions about phase changes, the states of matter and how...

Fifth graders discuss the differences between chemical and physical changes. In groups, they complete experiments and discover how a physical chnage can be reversed. To end the lesson plan, they review the steps of the water cycle and...

Le Chatelier's interest in thermodynamics and building materials such as cement and plaster led to the Le Chatelier Principle in 1884. Activity 13 in a series of 36 extensively explores chemical equilibrium. Learners read about...

Teaching is a balancing act! Keep things on an even keel with a comprehensive equilibrium lesson plan. The resource covers reversible and irreversible reactions, Le Chatelier's Principle, and the industrial applications of equilibrium...

Pupils describe and compare common properties of various classroom materials. For this science/matter lesson, students observe common classroom items and the materials they are made of to complete a list of common properties.

Students explore the energy changes from a liquid to a solid. They model the arrangement of a solid and the change in states due to changes in energy using desks and chairs. Assessment questions are provided in lesson plan.

The best part of learning about equilibrium is that nothing changes. Young chemists observe four demonstrations during this lesson plan: equilibrium in a saturated solution, equilibrium with an acid-base indicator, equilibrium with...
