Young scientists investigate chemical and physical changes to the states of matter—gas, liquid, and solid—as well as solutions and suspensions with a variety of demonstrations, grand conversation, and an interactive quiz to check for...

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...

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...

Fourth graders identify a physical change as one that results in a change in size, shape, or state of matter. After an initial teacher-led discussion and demonstration, groups of students get together to perform an experiment which...

Students observe the differences between physical and chemical changes in properties. Through the use of an interactive presentation, the students compare and contrast the changes and provide supporting examples of each type of change.

Students investigate chemical and physical changes in reactions. In this chemical and physical change lesson plan, students mix 6 different white substances with water, vinegar and iodine. They make hypotheses about each substance and...

Students investigate chemical and physical changes. In this physical and chemical change lesson plan, students perform 3 experiments in the lab to observe changes in matter. They determine that no new substances are formed in physical...

Sixth graders explore physical and chemical changes. In this physical science activity, 6th graders study vocabulary, discuss the changes they see in the world and look up information on chemical and physical changes. Students create...

Learners explore physical and chemical changes. In this chemistry lesson plan, students will go outside to observe changes seen in nature. Learners will then work in the lab to identify changes at different stations prior to doing a...

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...

Take part in a fun experiment and hold an impromptu bouncing contest with your class. Young scientists heat and cool balls before bouncing them to determine whether temperature changes affect how they bounce. The set of...

In this chemical and physical change worksheet, students use a sugar cube and observe its physical properties both when it is whole and after it is crushed. They heat the sugar cube and record 5 properties of the matter while being...

Fourth graders examine and identify chemical and physical changes in a variety of substances. They observe a vinegar and baking soda demonstration, and a water, laundry detergent, and Epsom salt mixture demonstration. They discuss the...

Fourth graders identify characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and that these properties can be used separate. Students describe the...

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...

Liquids, gases, and solids are the states of matter in which scholars investigate in a lesson plan that offers in-depth information and engaging activities that look into the three states and the changes their properties make when mixed...

There's a container for every matter—liquid, solid, and gas. Pupils design three different containers, each with the capability to hold one of the states of matter, and share their design with the class.     

Students observe examples of physical changes that can take place between the three states of matter and develop common sense and intuition in distinguishing between chemical and physical changes. They observe diagrams on the board from...

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...

An educational lesson focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form. 

Students investigate chemical and physical changes. In this chemical and physical changes lesson plan, students distinguish between a chemical and physical change when observing baking bread and hot dogs and bagels cooking on a grill....

Astronauts train underwater to simulate the change in gravity. An out-of-this-world unit includes three hands-on activities, one teacher demonstration, and a discussion related to some of the challenges astronauts face. Scholars apply...

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, they review the steps of the water cycle and...

Students break into four groups, starting at different stations. Each station should take about 10 minutes depending on prior knowledge of the topic. They then rotate when everyone is finished to the next station and discuss answers of...
