For 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.

Show young chemists what a chemical reaction looks like with two parts of a hands-on experiment. First, learners conduct a wet lab where they observe the reactants (baking soda and calcium chloride, with phenolsulfonphthalein)...

Graphic organizers, photos, diagrams, and text bring the world of chemical reactions to life. By viewing this presentation, young chemists learn how to recognize when a chemical reaction has occurred, and how to balance chemical...

Fourth graders identify the characteristics of a simple physical change. They describe objects by the properties of the materials from which they are made. Students discuss the different states of matter and their distinct physical...

Students examine water. In this chemistry activity, student examine the physical properties of water and how it changes from a liquid to a solid or a gas. This activity contains links to a second and third complimentary activity on...

Le Chatelier's interest in thermodynamics and building materials such as cement and plaster led to the Le Chatelier Principle in 1884. Activity 13 in a series of 36 extensively explores chemical equilibrium. Learners read about...

In this conservation of mass worksheet, learners design an investigation to demonstrate the Law of Conservation of Mass. Students describe their investigation, collect data, graph the data and write a conclusion about what they discovered.

Pupils explore the definition of matter.  In exploring matter lesson students get into groups and navigate the Internet to answer questions. 

Students observe changes in water. In this lesson about water and its forms, students perform an experiment to determine how water changes. Students analyze what causes water to be solid, liquid, or gas. Students record their...

In this chemistry of ice cream worksheet, students investigate colligative properties and how they affect freezing points while making ice cream. Students answer short answer questions to determine if freezing is an endothermic or...

Students observe crystals and their shapes and formation. In this crystal formation instructional activity, the teacher prepares crystal gardens for the students to observe, then the class finds examples of crystals in nature and observe...

Ready to mix it up? Learners step up to the plate and show what they know in the 12th installment of a 14-part series covering the states of matter. The quiz contains four questions testing the basics of emulsion chemistry.

Want to use dry ice in your classroom this Halloween but you're not sure how? A thorough packet of 13 dry ice activities showcases engaging ways to bring chemistry to life this October.

Students use indicator paper to determine if substances are acidic, basic, or neutral. They test for Ph levels in them. They investigate the effect of oxygen on darkening fruit cut and exposed to the air. They observe vitamin C as an...

Students 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.

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.

Due to surface tension, dew — a liquid, is spherical in shape. Learners explore the properties of liquids in activity seven in this series of 36. Beginning with its basic properties such as boiling point and moving through to surface...

Crystal comes from a Greek word meaning ice. Activity eight in a series of 36 has class members analyzing amorphous and crystalline solids and further classifying them based on their forces. They then explore solids, learning about unit...

It's time to increase the heat! Young chemists demonstrate heat transfer and heat capacity in an activity-packed lab, showing the transitions between solid, liquid, and gaseous phases of materials. Individuals plot data as the...

In this matter and change worksheet, students answer 24 questions on topics such as elements, compounds, mixtures and chemical reactions. Students answer questions about the properties of matter such as their physical state and shape. In...

Middle schoolers engage in a lesson that is concerned with the concept of water chemistry. They conduct research using a variety of resources. Students also consider an experiment to observe how water has the abiility to exist as three...

Students differentiate the three states of matter. In this chemistry lesson, students analyze graphs of heating and cooling curve of water. They complete a lab report and discuss results.

Do you think chromatography paper suffers from separation anxiety? Young chemists make soap, slime, silly putty, and experiment with chromatography in this lesson plan. The material includes clear instructions for each experiment along...

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.
