Students find the percent of oxygen in potassium chlorate. In this percent composition lesson plan, students heat a solution of potassium chlorate using a catalyst, manganese dioxide, to decompose the potassium chlorate and release...

Here is a laboratory exercise in which chemistry masters conduct an oxidation reaction to change ethanol into ethanal. They compare the original alcohol to the resulting aldehyde by forming a precipitate. This activity is aimed at...

In this chemistry worksheet, students describe an atom, its parts, the charges of these parts, and atoms life functions. Then they explain what the octet rule states for the placements of electrons around the nucleus of an atom. Students...

In this word search worksheet, students locate 20 words related to science. The word list includes volume, mixture, and solute.

How can you turn an ice cream activity into a scientific investigation? It's easy if you know ionic compounds, heat transfer, and the exothermic and endothermic process. Learners will explore the science behind freezing, insulation, and...

In this percentage worksheet, students calculate percentages given various types of problems. They calculate percent of compounds in a solution, they calculate mass of compounds given percentages of solutions, and they percentages of...

Don't you wish you had the time to type up a study guide for your chemistry class? With this resource, there is no need! A chart comparing the properties of metals and non-metals tops the handout, followed by notes on the reactivity...

Anytime you make concepts clear with role playing or hands-on experience, it's a win for the whole class. Ping-Pong balls are used to represent carbon in a carbon cycle role-play activity. In small groups, children first discuss what...

In this matter worksheet, high schoolers compare and contrast chemical and physical properties and explain the relationship between a pure substance and a mixture. Students review the properties of metals and nonmetals. This worksheet...

Sixth graders complete several experiments about chemical and physical changes. In this physical and chemical science activity, 6th graders complete 6 experiments about chemical and physical changes. Students examine the processes of...

Young scholars design and create a compost pile in order to study the Nitrogen Cycle. They then use the scientific method to determine if plants grow better when they add organic matter from their compost pile to the plant's soil.

In this science worksheet, students apply science basic knowledge of chemistry to the puzzles that are listed for the four parts of the sheet while focusing upon the identification of a metalloid.

Students observe different substances under the microscope. In this space science lesson, students identify the different features of SEM images. They formulate a conclusion about the images of Mars meteorites.

Fifth graders study the properties of metals and use them to identify different properties.  In this metal properties lesson students complete a demonstration .

Three experiments involving pennies help young chemists see the chemical reactions between copper and other elements. The first experiment is rhetorical (it prompts students to leave a bright penny out for a year) but the second two...

In this science worksheet, learners explore the learning outcomes for a unit on chemical reactions. Students define 60 vocabulary words and answer a list of questions for each topic.

Young scholars explore energy by researching fuel usage on Earth. In this fossil fuel lesson, students define fossil fuels, the energy created by burning them, and the impact on the environment when using them. Young scholars conduct...

Young scholars explore the technique of chromatography to separate compounds in a mixture. In small groups, they separate by paper chromatography and identify the major and accessory photosynthetic...

In this chemistry review worksheet, students answer a variety of questions about matter, elements, the kinetic theory, chemical and physical properties and the distillation process. They complete a concept map about matter.

In this chemistry worksheet, high schoolers select answers to 24 multiple choice questions using the drop down box. They identify the different atoms involved in the chemical reaction.

Students complete a unit of activities to learn about states of matter and how to measure matter. In this matter lesson, students complete 8 lessons to learn about matter, its states, and how to measure matter.

In this atoms worksheet, learners review protons, neutrons, electrons, molecules, compounds, and ions. This worksheet has 10 fill in the blank and 3 problems to solve.

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

In this radiochemistry instructional activity, students read about how scientists learn more about elements using radioactive isotopes. Students answer three critical thinking questions about the reading and radiochemistry.
