Students examine stoichiometry. For this chemical reaction and mole lesson, students complete an experiment based on readiness levels to explore that changes are quantified in chemical reactions.

This compact collection of slides explains the history and use of the mole unit. Relative atomic mass, as John Dalton understood it, is explained. Avogadro's number is also introduced. The mole, or the unit for the amount of a substance,...

Students pretend they are water droplets traveling through the water cycle. Using their text, they discover the steps in the cycle and the different paths water can take. They write a report about their journey through the water cycle...

Students are introduced to the mole concept using a discovery-based method. Lesson includes activities with candy that allow students to discover the rules for mole-item, item-mole, mole-mass, and mass-mole conversions.

Young scholars explain concepts related to static electricity, based on a single example: lightning.

In this molecules worksheet, students read about the discovery of new carbon molecule which has been nicknamed buckyball. Students answer 2 short answer questions.

Learners experiment to gain understanding of how a greenhouse retains heat.  In this greenhouse lesson plan, students work with soda bottles and simulate a greenhouse. Learners compare data from a vented and intact bottle. Students...

In this chemical and physical change worksheet, students are given details about chemical and physical changes. They are given 2 examples using water and salt and they identify 15 statements as chemical or physical changes. Students...

Students recognize that some changes to matter are reversible and some are not.  For this matter lesson, students experiment a physical and chemical change. Students record experiment results in their science journals. Students act...

In this states of matter instructional activity, students learn about the 3 different states of matter and how matter shifts states. They then answer the 20 questions in the packet. The answers are on the last page.

Students interpret basic chemical formulas. When class begins, students interpret a "chemical formula" for fruit salad. After they interpret the recipe, students use the same strategies to identify chemical formulas. They evaluate the...

In this weird water worksheet, students read for information and assess comprehension. In this true and false, fill in the blank, and multiple choice worksheet, students answer ten questions.

Students examine the concept that static electricity is a phenomenon that involves positive and negative charges. They explore the Static Electricity section of the Science, Technology and Engineering website to learn more about the...

In this covalent compounds learning exercise, learners answer 8 questions about bonding in covalent compounds, covalent bonds, and diatomic molecules. Students draw 2 dot diagrams showing covalent bonding. They answer 4 questions about...

Students experiment with solids and liquids. In this mixtures of matter instructional activity, students combine matter to form solutions. Students hypothesize, test, and analyze the data to draw conclusions. The instructional activity...

In this chemical reactions worksheet, students compare endothermic and exothermic reactions, closed and open systems, and reactants and products. Students review physical and chemical changes and how to balance equations. This worksheet...

Don't be fooled by the title - this biology quiz could serve as an AP biology or college-level biology quiz. Some of the molecules represented may be difficult to identify without seeing the textbook from which this is based. It could...

Learners differentiate physical and chemical change. In this chemistry lesson plan, students list examples of those changes. They apply what they learned in a Jeopardy style team game.

In this matter learning exercise, high schoolers compare and contrast chemical and physical properties and explain the relationship between a pure substance and a mixture. Students review the properties of metals and nonmetals. This...

Students examine mixtures and solution properties by making a borax polymer. In this chemical reactions lesson, students make a putty out of borax solution mixed to create a polymer.

Eighth graders experiment to determine the number of drops of water a heads up penny hold. They create a stem and leaf graph of the class results and use the data for further experimentation on a tails up penny.

Students decompose glucose and write an equation for the reaction. In this decomposition reaction lesson plan, students burn a sample of glucose and test the products for water using cobalt chloride paper. They write a balanced equation...

In this organic chemistry reactions instructional activity, students are given a table with 8 different types of reactions that occur with organic molecules. Students answer 3 questions about the reactions given in the table and indicate...

Learners investigate temperature and chemical reactions. They explore the effect of temperature and particle size has on the rate of a simple chemical reaction. In addition, they graph their results and answer assessment questions.
