In this percent composition worksheet, students find the percentages of atoms in compounds and they determine empirical formulas given the percent of each atom in a compound.

Students participate in an investigation in which they compare a polyethylene bag designed for recycling or disposal with a polyethylene food storage bag. Students use hexane to determine the differences between the low density...

Need to prep your science learners in math? Here is a resource that serves as a review guide to support your scientists with the math they need to be successful in chemistry. Comes with basic algebraic problems and a review of...

In this reactions worksheet, students complete the given reactions by writing the products. Students do examples of composition, decomposition, single replacement, double replacement, and combustion reactions. This worksheet has 54...

How do green plastics reduce waste and environmental pollution? Budding scientists create and test a variety of compounds used in green plastics during an insightful experiment. Beginning with startling statistics and ending with...

Balancing equations is a foundational skill for starting chemists. There are a few slides in this PowerPoint with colorful diagrams that help to explain how. Unfortunately, the presentation begins with an unrelated table of contents and...

Pretty purple slides present a plethora of jargon related to genetic engineering. Most of them have one term across the top and a brief explanation of that term below. They are arranged in alphabetical order, which may not be the most...

Students conduct a series of experiments to explore Graham's law. In this chemistry lesson, students differentiate effusion and diffusion. They perform calculations using Boyle's, Henry's, Charles' and Graham's Laws.

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

Students list the steps an epidemiologist takes to detect a pathogen. They role-play as scientists as they investigate the cause of the outbreak in Japan during 1996.

In this colligative properties activity, learners solve eight problems. They calculate molarity, molality and grams of substances in addition to using colligative properties to calculate solutions.

Students examine the importance of good quality safety gear. In this investigative lesson, students will tests various polymers, collect data, and analyze the data to determine which polymer is best for safety helmets. They will design a...

The details and definitions of Biotechnology and genetic engineering are very useful, but this is a very long PowerPoint with no images or ways of breaking up the information. The slides are nicely composed and relevant, so this could be...

Many types of cancer treatments now depend on nanotechnology—a big "little" discovery. Scholars begin by removing "malignant" tissue from simulated brains, one using fluorescent markers thanks to nanotechnology and one without. This...

In this chemistry worksheet, students examine the concepts of mole and molarity in order to apply in the laboratory setting. The sheet includes in depth background information.

Wow! This comprehensive collection of slides will walk your chemistry class through the foundation of chemical reactions, teach them to balance equations, differentiate types of reactions, and calculate stoichiometry problems. This...

This worksheet would make a nifty quiz on the laws of thermodynamics. Nine multiple choice questions assess high schoolers' understanding of energy transfer, specific heat capacity, phase change, fusion, and vaporization. It is short but...

Love is in the air? Wrong — nitrogen, oxygen, and carbon dioxide are in the air. The final lesson in the series of five covers the impact of temperature on gases. Scholars view a demonstration of gas as a type of matter before performing...

Young scholars explore the strength of intermolecular attractions. They make slime and compare the difference in the physical properties of sheet and powdered polyvinyl alcohol with polyvinyl acetate.

How many planets can you name? Did you get all 13 in our solar system, including the dwarf planets, or were you surprised when you read there are 13 planets? The lesson plan helps scholars understand the scale of the universe including...

Should Pluto be considered a planet or a dwarf planet? Scholars research planets in our solar system to understand their similarities and differences. It also includes memory activities related to the order of the planets. 

All soil is not created equal! A lab activity asks learners to collect and analyze soil. Specific calculations determine the amount of sand, silt, and clay in a sample and allow individuals to identify the soil texture. 

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

A valuable resource provides a list of concepts that young chemists should grasp. The topics include energetics, kinetics, equilibria, redox reactions, and the halogen group. Employ this as a guide for your own curriculum planning, or a...
