Pupils investigate condensation in the lab. In this chemistry lesson, students explain molecular motion during phase changes. They relate this observation to Earth's weather conditions.

Students examine the observed world, molecular world, and the symbolic world of chemistry. They observe a demonstration of the conductivity of solutions, describe the properties of acids and bases, and predict the outcome of solution...

In this solids worksheet, students review terms associated with solid matter including, freezing and melting point, viscosity, and Brownian motion. This worksheet has 1 short answer and 14 matching questions.

Get ready to kick things up a notch! Young scientists explore the effects of catalysts using a fun interactive. Learners start the reaction without using a catalyst, then add one over time to examine its effects on reaction rate.

Young scholars examine molecules and the changes in energy of a system.  In this energy systems lesson students complete a lab activity and describe changes of state.

Students describe how molecules of the different phases of matter move according to the Kinetic Theory. In this chemistry lesson, students observe and participate in teacher demos. They give real world applications of the kinetic theory.

Different substances can have different densities, but can the same substance have different densities? Lesson explores the effect of temperature on the density of water. Extension idea connects the concept of how melting ice in lakes...

When making sweet tea, why do people dissolve the sugar in hot tea instead of cold tea? The class discusses the previous lab and builds upon it. Working in groups, they design an experiment to determine how temperature affects the...

Love is in the air? Wrong — nitrogen, oxygen, and carbon dioxide are in the air. The final lesson in the series of five covers the impact of temperature on gases. Scholars view a demonstration of gas as a type of matter before performing...

Once your physical science stars have a grasp of the different forms of energy, use this resource to get them putting the energy to work. Small groups choose from seven different project options and work together to build an energy...

Lead your class to construct a solar still on campus to demonstrate how water can be extracted from the soil. The power of solar energy is emphasized, as is the concept of how capillary water can be recovered and purified by using a...

Students observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water

This worksheet would make a nifty quiz on the laws of thermodynamics. Nine multiple choice questions assess high schoolers' understanding of energy transfer, specific heat capacity, phase change, fusion, and vaporization. It is short but...

Calories are not tiny creatures that sew your clothes tighter every night, but what are they? A science instructional activity, presented at multiple levels, has learners experiment with heat, heat transfer, and graph the...

All soil is not created equal! A lab activity asks learners to collect and analyze soil. Specific calculations determine the amount of sand, silt, and clay in a sample and allow individuals to identify the soil texture. 

Is your class ready to size up the topic of diffusion? Help them get cell shape savvy with a well-written handout. The resource covers how substances such as oxygen passively move through the cell membrane and how cell size and shape...

Young scholars develop a scientific model of gas behavior. In this gas lesson plan, students observe different balloons filled with different densities of gases. They complete an activity where they model the behavior of gases using...

Students answer the question, "Why do Eskimos build houses out of ice to keep warm. Since heat goes from hot to cold, don¿¿¿t the ice walls take away the warmth inside the house?" They explain how snow or ice can actually be insulators.

Students investigate the concept of diffusion through a membrane. They do this through the conduction of a simple experiment. Students make observations while determining if the smell of different chemicals seeps through the balloon...

Eighth graders read and interpret the Periodic Table. They also make decisions on how to group and arrange different kinds of matter and draw the structure of atoms of pure elements. Finally, 8th graders contrast and compare basic...

How does heat move from one item to another, even when the items are in different states of matter? Pupils experiment with adding washers to hot water and adding hot washers to room temperature water to observe the heat transfer. 

Who likes magic shows? In the fourth of five lessons, pupils view a scientific magic trick. The ball fits through the ring easily, but then moments later, it won't pass through anymore. What changed? Can we reverse the change? Scholars...

Did you know that jumping spiders sometimes wear water droplets as hats? A seventh grade science lesson introduces the concept of what makes up water: tiny molecules that are attracted to each other. Starting with a...

in this working with tenses worksheet, students identify time expressions in sentences. Students then determine the tense of each of the verb phrases and create new sentences.
