Students investigate the concept of a thermodynamic system. The difference between a state and phase is defined as part of the experimental explanations given in writing. Students conduct experiments to demonstrate laws of science like...

In this heat activity, students determine the heat gained or lost when matter changes phases. Students review the energy flow through ecosystems by comparing trophic levels and food webs. This activity has 10 fill in the blank, 5 short...

In this chemistry worksheet, students calculate the freezing point of a given solution. Students calculate the final temperature and state of the water in a given problem. Students solve several problems provided.

Pupils draw a diagram to show the fluid mosaic model of a membrane. They explain how hydrophobic and hydrophilic properties help membranes hold their shape. They identify the functions of different cell membrane proteins as well.

Young scholars identify fossils. They identify evidence of change over time when given pictures of fossils to determine the proper sequencing. In addition, they determine evolutionary relationships by comparing embryonic structures.

Students analyze and evaluate evidence that matter is made of tiny particles. They observe a series of phenomena involving solids, liquids, and gases to make inferences about the spacing, interactions and relative kinetic energies of the...

Eighth graders are introduced to the Earth's hydrologic system including the cycling of water in the atmosphere and the movement of water on the surface of the planet using the Great Lakes watershed as an example.

Each of the slides here gives a definition, equation, or calculation example for a component of force and motion. This large collection covers topics from momentum and Newton's laws to centripetal forces and simple machines. Animations...

In this matter worksheet, students review the states of matter and the gas law formulas and equations. Students then complete 7 multiple choice questions and 6 problems.

Demonstrate the lunar cycle to youngsters using flashlights and lollipops. The procedure is somewhat vague, so it will need to be modeled for them before turning them loose to try it. The questions that follow the activity are not...

In this kinetics worksheet, learners solve twenty one problems related to reaction rates, half life, reaction orders, catalysts, and activation energy.

Students examine a frog's life cycle. In this amphibians lesson, students read a book about frogs and discuss how frogs are born and how they grow.  Students complete worksheets on the life cycle of the frog, and hold a discussion...

Students explore human growth and development as they participate in class activities, reading and discussion. Worksheet and handouts are included in the lesson.

Students describe the properties of solids and liquids, and explain how a semiconductor works.  For this atom lesson students demonstrate the bonding properties of carbon and silicon.

In this chemistry practice worksheet, students select the correct response to the given questions. Students apply knowledge about the states of matter, finding vapor pressure and atmospheric pressure.

Middle schoolers 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...

This lesson will introduce a phase change diagram for water, relating energy to progress of a phase change, with labeling including specific heat values, heat of fusion value and heat of vaporization value.

This lesson will introduce a phase change diagram, and show how a substance changes from one phase to another. It is 1 of 3 in the series titled "Phase Changes."

By the end of this section, you will be able to interpret a phase diagram; state Dalton's law; identify and describe the triple point of a gas from its phase diagram; and describe the state of equilibrium between a liquid and a gas, a...

Learn about the phases of matter in this section of a college textbook. Section defines the phases of matter and discusses how to interpret a phase diagram. Also explored is partial pressures and Dalton's Law. Section also includes...

Learn how to interpret a phase diagram, explain Dalton's Law, and describe the state of equilibrium between a liquid and a gas, a liquid and a solid, and a gas and a solid. This resource contains in-depth explanations and multiple...

This lesson will introduce a phase change diagram, and show how a substance changes from one phase to another. It is 3 of 3 in the series titled "Phase Changes."

This lesson will introduce a phase change diagram, and show how a substance changes from one phase to another. It is 2 of 3 in the series titled "Phase Changes."
