Accomplished chemistry learners set up a calorimeter and measured the energy released by various alcohols: methanol, ethanol, and either propanol or butanol. Lab masters will first need to design their tables for recording data. Consider...

A cold seep is an area on the ocean floor where hydrocarbons leak from the earth, creating entire unique biomes. Learners explore cold seeps, photosynthesis in the ocean, and its limitations due to loss of sunlight. They further explore...

Turn aluminum cans into pickles! An engaging experiment has learners chemically change aluminum into a substance with many purposes including the manufacture of pickles. After performing the chemical conversion, the experimenters verify...

If your pupils think a catalyst is a list of their cats, then this might be the lesson for you! Young chemists study the effect of temperature, catalysts, concentration, and particle size on reaction rates during four different...

Each of the slides here gives a definition, equation, or calculation example for a component of force and motion. This large collection covers topics from momentum and Newton's laws to centripetal forces and simple machines. Animations...

Students are able to draw a diagram of the light reactions and briefly describe what is occurring throughout the process. They are able to explain where each reactant/product in the photosynthesis equation comes from/goes during the...

This review sheet will be very useful to test your pupils' understanding of battery structure and redox reactions.  The questions ask for equations to be balanced and for the traditional equipment setups to be drawn and labeled....

Students investigate the chemistry of coal. This lesson serves as a review of conservation of mass, simple reactions and equation balancing. During the lesson, students research chemical components of coal, as well as environmental...

In this energy worksheet, students review the processes that create energy for a cell: photosynthesis and cellular respiration. This worksheet has 11 fill in the blank and 14 short answer questions.

Scientists can't observe bonds breaking or forming, so how do they distinguish between exothermic and endothermic reactions? Young scholars complete two experiments to do just that. They monitor temperature change and calculate the...

Laughter may be the best medicine, but aspirin is also important. Young chemists analyze aspirin tablets using titration in this lab experiment. They then repeat the entire experiment using a different aspirin brand. 

The purpose of this lesson involves reviewing nomenclature and molecular formulas as well as introducing naming molecular compounds and identifying acids. The students investigate and understand how conservation of energy and matter is...

Students calculate stoichiometrically the amount of carbon dioxide that would be emitted from burning a mole of varios alkanes that comprise fossile fuels. If the energy released from burning a mole of these alkanes is known, then the...

In this reactions worksheet, learners state the differences between a coefficient and subscript and an exothermic and endothermic reaction. Students review the different types of reactions. This worksheet has 13 short answer questions.

In this chemical reactions worksheet, students learn about the 5 types of chemical reactions as well as endothermic and exothermic reactions. Students are given 5 equations to balance and they identify the type of reaction for each...

In this chemical reactions worksheet, students follow a flow chart to determine what type of reaction is occurring. Students then classify reactions and balance the equations. This worksheet has 2 short answer and 10 fill in the blank.

Several factors affect the rate of a chemical reaction including temperature, surface area, and concentration. Using an experimental approach, learners explore the effect concentration has on this rate while maintaining consistency with...

Students write a balanced chemical reaction. They articulate how burning fossil fuels increase the carbon dioxide levels in the atmosphere. Students incorporate all the environmental risks involved as well.

Students will discuss the de Brogile Hypothesis and state the circumstances under which the wave nature of matter is observed. They will also calculate the wavelengths of matter waves.

Students explain how the food chain works. They contrast predators with prey and describe their function in nature. Students discuss how the food chain aids in keeping nature balanced. In small groups, they play a game that simulates the...

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

Learners investigate Newton's Second Law of Motion as they predict the effect of a payload on the amount of energy needed to lift a rocket vertically. The constraints of the weight of the equipment carried to Mars is compared to the...
