Middle school chemists visit interactive websites in order to discover what happens to molecular motion when heat is added to matter. They conduct an experiment that demonstrates the expansion of matter with the addition of heat. A lab...

Looking for a full-color, labeled water cycle diagram? You found one! From evaporation to precipitation to plant uptake and everything in between, it's all here and beautifully illustrated. 

Viewers learn how to identify the substances in a chemical reaction, how to balance it, and the different types of chemical reactions by watching a presentation that also includes a review of monomers and polymers. The presentation...

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...

Learners 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...

Learners describe the motion of solids, liquids and gases. In this chemistry lesson, students describe how temperature affect motion of the particles. They determine the physical properties of each phase.

In this water instructional activity, students read a 1 page article on water, fill in the blanks of 3 words with their missing letters, fill in a crossword puzzle containing 5 clues about water and answer 1 short answer question....

Students develop an understanding of waste and its effects.  In this managing waste lesson students participate in one of a few activities including creating a poster, summarizing an article or writing a research paper. 

In this molecules worksheet, students review how temperature and pressure affects molecule density. Students compare the volume of a balloon as temperature changes. This worksheet has 9 fill in the blank, 8 true or false, 1 short answer,...

Eighth grade physical science classes examine why the ice on which hockey is played is slippery. They do so by discussing phases of matter and the molecular motion in each. They read an article on a website and write out answers to...

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.

solid, liquid, and gas. The three different forms of water are the subject of the article used to assess reading comprehension. After reading the article, kids respond to a series of comprehension questions based on the text.

First graders observe examples of the three states of matter and identify matter in each of the three states. They make glitter wands to remind them of the three states of matter: solid, liquid and gas. Pupils brainstorm and record...

Dry ice isn't dehydrated water, and young scientists learn why in this fascinating presentation. After watching a video, they complete three different activities using dry ice. Upon completion, they discuss the scientific...

Your chemistry class is sure to love this experiment on column chromatography, as demonstrated with chalk sticks and felt tip markers. Pupils use sidewalk chalk (another inexpensive form of chalk stick) to demonstrate adsorption and the...

Make a splash with young scientists as you teach them all about water using this activity packet. Thirstin, a cartoon glass of water, walks children through the water treatment process, teaches them about different sources of water, and...

Students will use water, cornstarch, eggs, and more to explore the different states of matter. They will make observations of an unknown substance called "Oobleck" and test its liquid and solid properties. This would be a great lesson to...

Students study the vocabulary of the states of matter. For this states of matter vocabulary lesson, students investigate and study the meaning of the words solid, liquid, and gas. They experience demonstration lessons that give them...

In this physical and chemical change worksheet, students calculate the entropy change involved in different chemical changes. This worksheet has 4 problems to solve.

Second graders discover how matter changes from one state to another by observing melting ice cubes. They decide on means to warm the ice and predict what will happen. Students record how long it takes for the cubes to melt.

In this matter worksheet, students watch a movie and then compare the differences between compounds and mixtures. This worksheet has 16 fill in the blank questions.

Young scholars perform experiments in pairs to visualize the changes in water during freezing and melting. In this properties of water lesson plan, students use their senses and inquiry tools to understand the changes in state of water....

Use the accompanying presentation and colorful technology sheets to introduce your class to the 10 different energy technologies. Connect kids to an interactive computer tool that allows them to combine different types of power...
