Third graders take note of the changes in the water level in a cup of water that is left out. Using a model of the water that depicts a lake and landscape that is being heated by a heat lamp, the students observe precipitation, and...

Students explore the physical process of melting. They observe melting ice and answer questions related to energy transfer during phase changes.

Determine physical properties of potential packaging materials. Continuing from previous lessons in the series, the resource asks groups to identify physical properties of the substances. They test for conductivity, solubility, water...

Model the transfer of energy during a typical 24-hour period. Young scholars use a game-like approach to learning the patterns of heat transfer through the day and night. Groups of four exchange different tokens as the energy...

Learn about the factors that affect the way oxygen dissolves in salt water with a chemistry lab. After studying the molecular structure of water, young scientists figure out how aeration, temperature, and organic waste affect...

Who can grow the best crystals? Challenge class members to develop strategies for enhancing growth in the crystals. Through a lab investigation, learners study the properties of crystals and test the effectiveness of different...

In the 19th activity of 22, learners determine if distance from a light source affects photosynthesis. Participants capture oxygen in straws and find that the amount of water the gas displaces is proportional to the rate of photosynthesis.

Your young environmentalists can calculate their carbon footprint and discuss ways to reduce it with a worksheet about climate change. After reading a handout about what impact one's carbon footprint can have on the environment, kids...

How do we clean up oil spills and other pollutants in the water? Explore water treatment strategies with a set of environmental science experiments. Groups remove oil from water, work with wastewater treatment, and perform a water...

Fifth graders watch a demonstration in which a balloon is inflated using the gas created by combining vinegar and baking soda. Then, in groups, they combine various assigned substances and watch and record the results.

In this classification of matter learning exercise, students answer 15 questions about solids, liquids and gases, types of mixtures and compounds vs. elements. They also answer 2 questions about measurement and 1 question about a biome.

Young scholars 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.

In this physics review learning exercise, students review vocabulary words associated with speed, acceleration, Newton's Laws and simple machines, work and energy, magnetism, electricity, and harmonic motion and light. This learning...

Second graders explain the definition of hail and sleet. In this precipitation lesson, 2nd graders discuss when hail and sleet fall and the results of hail falling.

Learners experiment with various foods to determine fat and starch content. They rub jam, peanut butter, bananas, and other foods in a small circle on a piece of paper, and observe the results. If there is a high fat content in the...

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.

Learners categorize items into one of the three states of matter. They participate in a demonstration in which they represent particles of matter. Finally, they complete an experiment in which they "race" top see who can make acetone...

Eighth graders measure temperature changes and make drawings of the interactions between matter and energy. By measuring the temperature students can conclude if there are changes in levels of energy. .

Students differentiate physical and chemical change. In this chemistry lesson, students list examples of those changes. They apply what they learned in a Jeopardy style team game.

Fourth graders identify the characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and separate or sort items using these properties. Students explain...

Third graders rotate between three property stations, the solid station, the gas station, and the liquid station. They experiment with each activity until the teacher gives the signal to change.

Students describe the history of materials. They use the kinetic (particle) theory to explain changes of state in matter and trace the flow of heat during changes of state and chemical changes.

High schoolers are able to give specific examples of what to do and what not to do during given safety situations, and classify materials as metals, polymers, ceramics/glass, or composites. They are able to distinguish between chemical...

For this properties worksheet, students write the correct term in the spaces beside each definition. Then, students unscramble the letters in the boxes to answer a riddle.
