Not many lessons on states of matter can hold a candle to this one! Junior chemists gauge the density of paraffin in both liquid and solid phases. They fill 60 mL syringes with different materials to experiment with compressibility and...

Who knew that learning about the states of matter could taste so sweet? This fun hands-on lesson captures the attention of learners as they use what they know about solids, liquids, and gases to create their very own batch of ice cream.

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...

Second graders identify the three states of matter by examining fishbowls with various contents. They discuss their observations and the characteristics of matter in each state. Pupils read the story The Rainbow Fish and look for...

There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

Explore the properties of gases through one activity and two investigations in which super scientists observe the changes gas makes when encountering different conditions.

Why does soda fizz when opened? Learners discuss the appearance of bubbles in soda bottles when opened. In groups, they design and complete an experiment comparing the amount of carbon dioxide dissolving in cold versus hot liquids.  

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.    

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...

Students explore the three forms of water and observe how it changes from a solid to a liquid to a gas. The concepts of condensation, evaporation and the introduction to the water cycle form the basis of this lesson.

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....

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Students observe a demonstration of the the three forms of matter - air, water, and solids - in plastic bags. After discussing the properties, they transfer them to a Venn diagram. Finally, students identify five items in the classroom...

Second graders discover what changes occur in various types of matter under different conditions. They make predictions about the changes in an apple left out in the air, water placed in a freezer, and a nail left in a cup of water. They...

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...

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...

Third graders define matter as anything that takes up space and has mass, recognize, through experimentation and observation, that matter exists in three forms, including solid, liquid, and gas, and discuss characteristics of each form...

Using a dry cleaner bag and a blow dryer, create a hot air balloon! The materials list suggests obtaining one dry cleaner bag per student, but since this is probably inconvenient, consider doing this as a demonstration during a lesson on...

Students define, give similarites and differences between solids, liquids, and gases. They compare and contrast a solid, liquid and gas in terms of shape, volume, compressibility, diffusion and density. Pupils classigy common...

Students list individual properties of solids, liquids, and gases. They examine that some properties have more than one state of matter. Pupils consider whether shaving cream, is a solid, a liquid, or a gas, or some combination.

Students use knowledge of the states of matter while creating an informational book on solids, liquids, and gases. They watch a class video about matter and then discuss what they know about the three types.

Eighth graders analyze questions posted on a large poster in the room and work in groups to record their response to the question on paper, rotating to the next question after two minutes have passed. They review the characteristics of...

Light is such an amazing thing! Elementary schoolers explore the wonderful world of light and shadow. The instructional activity is meant to be carried out on a whiteboard. Objects are placed in front of a light source, and learners must...

Students examine how heating causes substances to expand, and cooling cause it to contract. They investigate the states of matter.
