Students observe chemical reactions that produce obvious effects. They begin by exploring a different substance every day for one week. They compare the substances and examine how substances can be solids, liquids, or gases.

First graders discover that a chemical reaction is responsible for the effects seen with Crayola Color Wonder markers. They observe that the color changes are the result of a chemical reaction between chemicals in the Color Wonder paper...

Learners explore physical and chemical changes. In this chemistry lesson plan, students will go outside to observe changes seen in nature. Learners will then work in the lab to identify changes at different stations prior to doing a...

Learners investigate matter. In this physical science lesson plan, students will learn about matter, physical states, and reactions. There are a series of four lab activities that will be conducted.

Learners conduct labs to gain an overview of chemical reactions. They observe examples of synthesis, decomposition, single displacement and double displacement reactions. They identify certain products by the use of litmus and splint tests.

Students compare types of chemical change. In this chemical reaction lesson, students use a variety of household items to investigate different types of chemical change. Students will engage in a discussion about the dangers of chemicals...

In this chemical reactions worksheet, students write chemical equations, draw and label isomers, and predict products of chemical reactions. This worksheet has 5 drawings, 1 short answer, and 7 fill in the blank questions.

In this chapters 2 and 3 science guided reading worksheet, learners read corresponding material pertaining chemical reactions and the periodic chart answering 40 fill in the blank questions.

Learners explore the properties of enzymes. In this chemical reaction lesson, students explore enzymes through a Web-quest and investigative study. Learners will collect and summarize data and create a class presentation. This lesson is...

Fifth graders investigate evidence for changes in matter that occur during a chemical reaction.

Students recognize both a physical and chemical change in different substances. They determine which particles actually changed into different substances, and explain if it represented a physical or a chemical change.

Students use the characteristic of a chemical reaction to write a secret letter. In this chemical reaction lesson plan, students will use common house hold products including iodine, lemon, and notebook paper to produce a chemical...

In this chemical compounds worksheet, students write in the IUPAC name for chemical compounds, draw structural formulas, and classify reactions as either oxidation or reduction conversions. This worksheet has 2 drawings and 5 fill in the...

Written for an introductory organic and biochemistry course, this exam will challenge your class. They label functional groups and stereocenters on drawings of molecules, draw structures given the name, complete drawings of chemical...

Students determine the meanings of concentration, surface area, and catalysis through an experiment. For this lesson about chemical reactions, students participate in an experiment. Students complete three different parts of the...

Students study volcanoes using a chemical engineering project. In this volcanoes lesson, students create a model town and discuss the properties of a volcano. Students then make a volcano using a chemical engineering format for their...

In this Lewis structures worksheet, students identify and describe what Lewis structures or dot diagrams are and how they illustrate the valence electrons in an outer shell. Then they use a periodic table to determine the numbers of...

This biochemistry practice exam queries takers on the organic molecules. Pupils write IUPAC names, identify boiling and melting points of different compounds, and more. This is definitely designed for a college-level biochemistry course,...

Students study about electrochemistry by increasing their understanding of electron transfer and its role in chemical changes. They explain that energy appears in different forms. Heat energy is in the disorderly motion of molecules.

For this chemical compounds worksheet, students write the name of compounds from their chemical formula, balance equations, write electronic configurations for elements, and draw Lewis dot structures. This worksheet has 8 fill in the...

Learners explore physics by participating in a flight experiment. In this rocket design lesson, students discuss the scientific process and how chemical reaction can create the energy needed to boost a rocket. Learners utilize...

Students engage in three short, hands-on, in-class demos which expand students' understand of energy. First, using peanuts and heat, students see how the human body burns food to make energy. Then, they create paper snake mobiles to...

In this chemistry worksheet, students complete 15 short answer questions and problems on empirical and molecular formula, naming and writing chemical formula of compounds.

In this metabolism test review, students define several terms. Students write balanced chemical equations for aerobic cellular respiration. Students complete several multiple choice questions.
