In this thermochemical equations worksheet, students read about and practice writing equations for thermochemical reactions. They also sketch enthalpy diagrams of the equations if applicable.

In this moles worksheet, students read about mass, formula mass and moles. They calculate the masses of given numbers of moles of compounds and they calculate the number of moles of given masses of compounds.

In this lipid worksheet, high schoolers answer questions about the structure and functions of lipids. They read about the three main lipids in the body including triglycerides, phospholipids and cholesterol and answer questions about each.

In this isomer instructional activity, students use molecular model kits to build isomers. Students work in groups and draw and name the isomers they build. They answer 9 questions about both geometric and structural isomers.

In this aliphatic worksheet, students are given eight hydrocarbon molecules. They determine if they are alkanes, alkenes or alkynes. They draw a diagram of each and indicate if they are saturated or unsaturated.

Third graders investigate the three states of matter and the properties of materials as they undergo physical changes. They identify examples of each type of matter, role-play atoms in solids, liquids, and gases, and conduct an...

Learners determine that the rate of reaction is affected by temperature, surface area, concentration of reagent, and addition of a catalyst or inhibitor. They observe that on December 3rd, 1984, 8000 people died when the chemical plant...

In this bonding worksheet, students write the chemical formula, the name of the alkane, the structural formula and the condensed formula given the number of carbon atoms in each alkane.

Students investigate moles and Avogadro's hypothesis. In this moles lesson plan, students complete a worksheet by finding the volume of 1 mole of each substance given its density and they find the number of molecules, the formula, the...

For this triboluminescence worksheet, students use wint-o-green Lifesavers to observe a chemical reaction that gives off light. They break a lifesaver up with a hammer and make observations and they chew a lifesaver and make...

In this stoichiometry instructional activity, students review definitions and equations associated with molarity, density, atomic mass, molarity, and dilutions. This instructional activity has 18 word problems.

In this chemistry review activity, learners solve a variety of problems including balancing equations, solving for unknowns using dimensional analysis, finding percent yields, limiting reactants and empirical formulas.

Students articulate the difference between the terms heat and temperature. They calculate the amount of energy associated with a given temperature rise and design an experiment to measure the energy of a fuel.

In this Newton's Second Law worksheet, students answer 13 questions about force, mass and acceleration. They calculate weight, force, masses and acceleration of objects.

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

Students create a garden.  In this ozone lesson, students discuss ozone injury, identify plants sensitive to ozone, and then plant their own ozone garden.

Students investigate the carbon dioxide content of different sodas. In this chemistry lesson, students explain why PET containers are preferable than HDPE for soda bottles. They collect data and graph them.

Learners explore how and why heat is produced from things that give off light, from machines, or when one thing is rubbed against another. They participate in several hands-on activities designed to help them realize that heat is related...

Students divide substances into categories: made of chemicals/not made of chemicals, synthetic/naturally occurring, and toxic/nontoxic. They observe a mystery chemical and determine what precautions they need to take when handling an...

Students distinguish between three phases of matter: solid, liquid and gas, on the molecular level. They compare and predict the relative compressibility of the three phases of matter through journal writings and drawings.

Learners investigate how the motion of the Foucault pendulum proves that the Earth is rotating. They research the Internet about pendulums and conduct an experiment online. They view a multimedia presentation about pendulums and read...

In this chemical reactions instructional activity, 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....
