In this natural resources worksheet, students compare examples of chemical and physical properties, balance equations, and calculate molar mass and moles. This worksheet has 12 problems to solve and 12 short answer questions.

In this classification of changes worksheet, students identify each example as either chemical or physical changes. Students also classify other examples as either element, compound, solution, colloid, or suspensions. In the other...

Young scholars learn how science affects foods. In this chemical reactions lesson, students make two kinds of ice cream. They evaluate the different changes based on the ingredients.

Eighth graders study the conservation of matter.  In this chemical reaction lesson plan students examine what happens during a chemical reaction and complete a lab activity. 

Students describe and define chemical reactions. They design a laboratory experiment, collect data and analyze data.

Students conduct an experiment to determine what happens to heat energy during a chemical reaction. They examine an endothermic reaction by observing a chemical reactions.

Students assume the role of police detectives and investigate chemical agents used to make explosives and suspected terrorists based on information provided. Students have a list of questions to lead their investigation and must produce...

Pupils participate in an experiment to demonstrate how mixing certain chemicals together can change the consistency of both chemicals. Glue, water, and borax are used to create a slime-like substance which is examined to determine how...

In this enthalpy equation worksheet, learners are given 3 examples of chemical reactions. Students then respond to 4 practice problems and 1 challenge problem in regard to heat and energy change and release.

In this compounds learning exercise, students name the given compounds from its chemical formulas and write the chemical formula from the compound name. This learning exercise has

Students observe and describe a chemical reaction. In this chemistry lesson, students record observations of the materials they will be using, then follow a written procedure to perform the experiment in a baggie and record their...

Pupils create a simple animation illustrating a chemical element in the periodic table. In this chemistry lesson plan, students create a new way to describe elements by using them in an artistic form.

Students investigate the differences between a physical and chemical change. They observe various demonstrations involving physical or chemical changes, make predictions, and record what they see, hear, and smell.

Eleventh graders study the use of the periodic table to develop a better understanding of the chemical elements.

Students design and conduct an experiment to test their ideas about how to speed up or slow down the rate of an enzyme-catalyzed reaction. They have access to an array of physical and chemical factors that might influence enzyme...

Students investigate the concepts of conservation of mass and simple chemical reactions. Students complete lab experiments and record all observations as well as conduct experiments on their own to determine which reactions created...

Young scholars measure the temperature change involved in the production of carbon dioxide by yeast. They also identify products and reactants in a chemical and balance the equation.

Students explore the effects of chemical reactions when cooking. Using the Internet, they research enzymes and then mix jello. They examine their results and test enzyme activity by adding pineapple to the jello. Finally, they test...

Students apply their comprehension of colligative properties to real-world situations. They review the concepts of physical and chemical changes. Students are reminded that science is used extensively in food-production. They are...

In this molarity worksheet, students are given balanced equations and they are to calculate the mass or volume of reactants and products. Students calculate the theoretical, percentage, and actual yield for chemical equations. This...

For this compounds worksheet, students identify molecules as compounds and provide a reason why they believe it is or is not a compound. Students write out chemical formulas. This worksheet has three problems to solve.

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...

In this proteins worksheet, students read about the chemical compound, protein. Students determine where proteins are found in the body and how enzymes help the body react. Then students complete 3 short answer questions.

In this chemical equations worksheet, high schoolers review the rules in balancing equations and then balance 11 chemical reactions.
