While scientists have identified seven states of matter, these puzzles cover the most common three. Scholars match the properties, particle motion, and particle picture to each type of matter. Three Sudoku-style puzzles review the data...

Do solids, liquids, and gases even matter? Scholars match the state of matter to its particle picture, size and shape description, and description of the arrangement of the particles. Once they complete that activity, they complete a...

Whether you're using a collection of Dr. Seuss books to teach basic math skills like counting, adding, and subtracting, or exploring the different states of matter by melting a crayon with a hairdryer, a series...

When water is a solvent in a chemical equation, we consider it an aqueous solution. Scholars match the name of four states of matter to their proper symbol in a chemical equation. Four puzzles provide repetition to help pupils remember...

Solids, liquid, and gas, the three states of matter, are the subject of a cross-curricular reading comprehension exercise that asks kids to first read an article about these forms, and then to respond to a series of questions based on...

Students describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas, state...

Students explore the components of matter. They discover what matter is, the states of matter, and how heat and cold cause it to change states in an online format. In addition, they complete internet-based lessons, activities, and quizzes.

Focus on inquiry-based learning in your science class with a series of activities designed for middle schoolers. A helpful packet samples four different texts, which include activities about predator-prey relationships, Earth's axis...

Eighth graders practice using correct vocabulary and apply content knowledge related to phases of matter when answering questions about situations or observations from everyday life.

Students use streaming videos, web sites, and hands on activities students to explore matter. They focus on how temperature affects matter and what the particles look like in the states of matter.

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

Over a period of 35 years, earthquakes and volcanoes combined only accounted for 1.5 percent of the deaths from natural disasters in the United States. The 15th lesson in a 20-part series connects the locations of earthquakes and...

Students identify three states of matter and recognize plasma as fourth state. They provide examples of matter that are classified in particular state and identify properties of each state of matter.

First graders break into groups of five students and are given 15 different objects and 3 posters. They group the objects into 3 different families with all the objects in each category placed on one of the posters. They choose whatever...

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.

Students identify the different states of matter. For this chemistry lesson, students differentiate the physical properties of the three states. They apply what they learned by playing a team game at the end of the lesson.

Fourth graders understand the benefits of recycling. In this recycling literacy lesson, 4th graders read an article and identify the main idea. Students understand the process of transfer to the landfill and discuss how recycling helps...

Second graders investigate the properties of solids and discover how to classify them. Using rulers, they measure various solids on display. In groups, they play an identification game where one students names a location, such as the...

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

Students examine the changing states of water. In this solid, liquid, gas lesson, students discover that water changes when heated or cooled. Students make predictions and then use the interactive whiteboard to "heat and...

Students identify and categorize states of matter. In this states of matter lesson, students study the pictures and sort them as liquids and solids.

Elementary learners listen to a story, then sort objects from largest to smallest at six different stations around the classroom. Adaptable for a large range of age and ability groups. 

Developing a test that uses primary sources to assess class members knowledge of the history of the United States is no easy task! Save yourself the time and stress and use a final exam that includes essay, multiple choice, and short...

Fourth graders examine matter and the periodic table of elements. In this matter lesson, 4th graders discuss atoms and their composition. Students explore the periodic table of elements and use it to spell words out of the elements.
