In this enthalpy equation worksheet, students 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.

Students explore how chemical reactions occur. After a brief discussion of household chemicals and how they work, students prepare a solution of invisible ink. Students create a message with their ink and watch the reaction as their...

Learners are taught that combustion of carbon in charcoal briquetts produces heat and light. They are shown how to find single displacement and double displacement. Students solve problem set of single and double displacement.

Students participate in a hands-on activity in which they observe conditions that are most conducive to the rusting of iron. They set up an experiment with 8 different nails in different situations with one of them acting as a control....

Middle schoolers observe chemical reactions using post-1982 pennies. They observe the reaction of an acid with zinc but not copper under the same conditions over a two week period.

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

Students 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.

In this physical and chemical changes worksheet, students will read 4 different examples of a physical or chemical change and will write in the effect of each of these changes.

Students are taught how enzymes enable chemical reactions to occur a body temperature and how the lack of enzymes in the body can cause problems in the break-down and absorpion of nutrients. They match up different enzymes with the...

Students investigate coal samples and analyze its drying loss under controlled conditions. They establish the loss in mass of a sample when heated under controlled conditions of temperature.

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 work in groups and observe chemical reactions inside zip-lock bags. They use all of their senses, except taste, to observe the reactions.

[Free Registration/Login Required] Create a science test that checks for student understanding in science, for common misconceptions, as well as for correct ideas. This is a list of key ideas related to Substances, Chemical Reactions,...

In this experiment, students will design and carry out a sequence of chemical reactions for the separation and identification of three metal cations from six unknown samples.

Students investigate how to build and launch a simple rocket that uses hydrogen and oxygen gases that will be mixed to propel the rocket. Students learn the principles of combustion reactions, kinetics, stoichiometry of reactions,...

In this lesson, Mentos candy and different types of soda are used to show examples of nucleation, surface tension, surface area, polar attractions, and supersaturated materials. A video will be used to show the examples and the students...

Expand your knowledge of Chemistry. Observe how ionic compounds are networks of electrically charged atoms.
