Chemical Composition of Everyday Objects

Through a station rotation activity, scientists complete 9 chemistry activities to complete this interactive worksheet. Concepts include molar masses, percent composition, accuracy vs. precision, mass of an object, scientific notation,...

In this flame test worksheet, students observe 13 chemicals while lit with a flame through a spectroscope. They indicate their observations, the actual color of the flame and the diffraction gradient of the flame. They complete the...

Eleventh graders research the elemental composition of a list of everyday substances. They find the types of bonds that hold the materials together and describe and compare the chemical structure of each. They complete a series of...

In this chemistry of art worksheet, students read about the chemical reactions that turn art made of different metals colors. They answer three questions about the chemical reactions related to metals and art.

Tenth graders observe various chemical reactions in the lab. For this chemistry instructional activity, 10th graders list the indications that a chemical reaction took place. They give real life examples of reactions they see everyday.

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

Two men want drinks and the first orders H2O. The second man orders H2O too, but he dies. Scholars apply their knowledge of H2O2 and other everyday chemicals during the activity. They match chemical formulas to common chemical names in a...

When asked to list everyday objects that require energy, most people list technology that use batteries or electricity. Through hands-on exploration, young scientists discover energy is much more than just circuitry. They play with...

Students investigate how to determine the percent composition of a mineral in an ore. In this mining an ore lesson plan, students use chocolate chips cookies to represent an ore and they remove precious minerals (the chocolate chips)...

Learners explore the reaction rates of an enzyme-mediated reaction through experimentation. In small groups, they use everyday objects to demonstrate the effects of environmental variables on enzyme function. Students graph and...
