Young scholars examine how nuclear reactions differ from other chemical reactions they have studied. They add up atomic masses of both the product and reactant side of an example of uranium decomposition, demonstrating mass loss involved.

Students examine the following concepts: If water supplies contain materials which rot or decompose, oxygen is used. Decay and decomposition require vast supplies of oxygen. The use of oxygen for decay of wastes may be a life or death...

Students observe what happens when sugar is dissolved in water and when it is heated. They weigh the products after each of the two experiments on a balance scale. Pupils distinguish between physical and chemical changes. Students are...

You may want to change the title of this chemistry PowerPoint to "Identifying Compounds in the Laboratory." Individual slides explain tests that can be performed to confirm what element you have: carbon dioxide, carbonates, and metal...

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...

Students participate in a laboratory investigation in which they observe the effect of temperature and pH on enzyme activity. Students also examine exposure to heavy metal ions and the effect that may have on enzyme activity.

Students demonstrate effects of waste on environment and ways of reducing it, observe how much packaging goes into bag lunches each day, and survey their families to assess awareness levels and household recycling practices. Lessons all...

In this thermodynamics instructional activity, students apply Hess's Law and review internal energy theory and heat capacity theory. Students use Boltzmann formula to calculate entropy and calculate the change in free energy. This...

In this atoms worksheet, students explore the different types of bonds, name compounds, and determine charges of molecules. This worksheet has 8 true or false, 9 fill in the blank, and 5 short answer questions.

Young scholars develop an understanding and appreciation of water purification techniques and their implications for health maintenance.

Students explore enzyme catalysis through a series of experiments. In this chemistry lesson, students determine the factors affecting catalysis. They explain the different uses of this process.

Students conduct a series of experiments on mulching. In this earth science lesson, students discuss the benefits of mulching on soil. They explore how different types of mulch affect plant growth.

In this chemistry worksheet, students practice creating chemical equations given the names of the compounds. The answers are included in the set of sheets.

Students explore Le Chatelier's Principle. In this lesson about chemical equilibrium, students do an experiment with several different activities . Students observe as they do the experiments and understand the outcome. Students become...

Students are assigned to groups, and determine each member's role in the group. They will design an experiment to determine a way to produce the three primary and five secondary colors. Students discuss color and mood. They listen to a...

In this equilibrium worksheet, students solve eight problems including determining the effects of changes to a system as it related to Le Chatelier Principle, calculating equilibrium constants and finding boiling points of solutions.

Students write the electron configuration of elements using the Aufbau principle. In this chemistry lesson, students build their own key that demonstrates the principle.

Learners go on an outing and note garbage near picnic tables. They brainstorm ways to be involved with anti-litter campaigns and write letters to local officials.

[Free Registration/Login may be required to access all resource tools.] Definition and example of a decomposition reaction.

This chemistry tutorial describes decomposition reactions with two examples.

This site provides an overview of the role of energy in chemical reactions.

A very simple reaction of acid (HCl) and metal (magnesium) to produce Hydrogen gas and metal salt will provide the volume of gas to evaluate. Learners will determine the amount of gas produced at room conditions and then using the...

Explains what a decomposition is and gives examples of different types and their chemical equations.

A good resource on chemical reactions, organized by topic: "Examples of chemical changes," "Chemical equations of chemical reactions," "Balancing equations," "Synthesis reactions," "Decomposition reactions," "Single replacement...
