Students investigate community issues with solid waste. In this mock trial lesson, students examine the issues of solid waste from an ecological and economical perspective. They will develop a mock trial which encourages preservation of...

Review the states of matter with your second graders using this resource. Learners first review what they know about solids, liquids, and gases. Then, they fill out a chart to show what they have learned. Finally, they engage in a...

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...

Use this volume of solids lesson to have learners find the surface area and volume of cylinders, pyramids, and prisms. They place cubes inside three-dimensional figures to determine the volume. Worksheets and answers are provided.

In this solids worksheet, students identify the characteristics of solids. They name solids and determine the number of faces. This three-page worksheet contains seventeen problems. Answers are listed on the last page.

Though it comprises only 5 percent of the world's population, the US generates 40 percent of the world's waste. Scholars learn about landfills, their safety, and other solid waste methods. They use experiments and research to learn more....

In this solids worksheet, learners identify true statements that match a given solid. They identify parallel lines. This two-page worksheet contains four problems. Answers are listed on the last page.

Third graders experiment with common household liquids and solids. In this chemical reaction lesson, 3rd graders discuss phase changes and experiment to find other ways to create gases. They use water, vinegar, lemon juice, flour, baking...

Students review the vocabulary terms solid and liquid. They also review that adjectives tell what kind, which one, and how many. The teacher introduces a "Oobleck" after reading "Bartholomew and the Oobleck" by Dr. Seuss. The students...

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 investigate the properties of plastic eggs filled with solids, liquids, and gases and use these observations to hypothesize whether a chicken egg is hard-boiled or raw.

Young scholars explore and identify phases of matter and compare the particle motion in solids, liquids, and gasses.

First graders locate and identify solids in the schoolyard. In this geometric solids lesson, 1st graders locate two solids on the playground. They work as a group to compare and contrast them according to shape, texture, weight, size,...

Scientists participate in a variety of hands-on experiments in this ten-day unit on the three states of matter. Lessons incorporate literature, a-v materials, and poetry to help students differentiate between solids, liquids and gases.

Young scholars explore solid waste and its effects on the environment. They explain some of the major problems caused by waste disposal and the use of landfills. They suggest ways to reduce the amount of solid waste going into a landfill.

Learners construct models of the way water molecules arrange themselves in three physical states - solid, liquid, and gas. They explain the molecular behavior of ice, water, and water vapor.

Students conduct an online experiment to discover what happens to solids, liquids and gases in different temperatures. In this states of matter lesson, students get into pairs and work in a virtual laboratory to manipulate...

Young scholars are introduced to the various states of matter. After watching a video, they discover how to compare the three states using its shape and volume. In groups, they participate in an experiment with solids, liquids and...

Learners investigate matter:solid, liquid, gas by conducting different experiments. In this states of matter instructional activity, students conduct hands on activities that allow learners to see first hand results....

Students explore solid, liquids, and gases. In this science lesson plan, students distinguish similarities and differences of matter and recognize that different states of matter may appear in one substance.

From gas to liquid condensation to solid frost, water undergoes phase changes before students' 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 of a...

Steal cubes sink, but steal ships float. Lesson explores the density of solids as well as the density of water in determining what will sink and what will float. A hands-on group activity helps pupils see that weight and volume are...

For this volume and surface area worksheet, students find the volume and surface area of different solid figures. Students complete 8 problems.

Eighth graders review solid geometry and measurement with a partner. They identify shapes and how they are measured then complete a word processing exercise on a computer. They exchange papers for grading.
