How do scientists determine when a solution is fully saturated? Scholars address the topic as they observe patterns of precipitation in various concentrations of ions. Using a well plate, pipette, and common chemicals, they collect data...

We know about the light spectrum, the age spectrum, and sound spectrum, but do chemical reactions also occur on a spectrum? Young scientists experiment with partial reactions on a spectrum and observe the color changes. Then, they...

Challenge young scientists to design their own experimental procedures. They write the procedure for properly preparing two grams of a water-insoluble ionic salt. To finish, they perform the experiment and collect data to prove their...

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...

Acid-base indicators are an essential part of any chemistry classroom. Individuals explore the color-changing feature of the important indicators in a vibrant hands-on activity. Using serial dilution, learners create solutions ranging...

The calculator has an interesting way of displaying numbers in scientific notation, but don't let that confuse your pupils! A lesson designed to give learners practice with scientific notation and calculators provides several practice...

Anyone that lives around snow knows that adding salts to water increases its melting point. Are there solutes that affect the boiling point as well? A scientific experiment has learners add different solutes to water and then...

In this statistics and probability worksheet, young statisticians solve and complete 13 different problems related to probability, percentages, and normal distributions. They consider data models, assumptions about the models, and find...

Seventh and eighth graders solve and complete 20 various types of short answer problems. First, they write a brief description of themselves including those as stated. Then, learners categorize the type of sampling used in various...

Many periodic tables mention specific heat, but how do scientists determine those numbers? Scholars attempt to find the specific heat of a metallic element by using a calorimeter. Three experimental trials ensure accuracy, and analysis...

Melting and burning might seem like opposites, but both exist as common examples of exothermic reactions. Scholars work with three different exothermic chemical reactions to determine the enthalpy changes. They measure and mix chemicals,...

Humans tend to huddle together when cold and move around more when warm, but do gas particles follow the same pattern? Scholars use a temperature probe, a pressure sensor, and air to study the relationship between temperature and gas...

Do your high school scientists know the four methods scientists use to communicate information? A simple experiment discovering the relationship between gas pressure and volume allows pupils to practice all four. After completing the...

As the most abundant element on the earth, hydrogen requires no replacement. Yet scholars learn to replace hydrogen with a metal to liberate the hydrogen gas. A simple procedure and data table include the necessary information and...

While this resource does not provide problems for chemistry learners to solve, it outlines skills that they should have and concepts that they should grasp. Topics include thermodynamics, periodicity, redox equilibria, transition metals,...

Estimating Errors in Chemistry is a detailed handout that illustrates the importance of calculating the percent error when working in the chemistry lab. There are no actual problems to solve, just notes and examples of calculations. Hand...

A table of the physical properties of metals and non-metals opens this high-school chemistry handout. Also covered are the chemical properties of metals and non-metals, reactivity, and fossil fuels. There are no specific questions to...

Neatly organized and easy-to-read, this chart summarizes five different molecular shapes: linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral. It associates shape with electron pairs and atom arrangement, and...

No practice problems are given on this handout; it is a detailed list of concepts to know and tips for working related problems in chemistry. Give this to learners as a study guide, or use it early in your career as a chemistry...

As the title suggests, this is a simply summary of fossil fuels. There are no questions to answer or problems to solve, just notes about fossil fuels. The notes cover how fossil fuels are formed, how we extract it, what humans use it...

If you use this as an outline for your chemistry lecture on metals, your young chemists will absorb a well-rounded overview. This is not a worksheet per se, but a useful summary of the behavior of metals. Save yourself some planning and...

Two versions of this handout are provided, the second with more detailed information on the same topics. Chemistry aces survey chemical reactions, heat energy transferred, and the action of enzymes by reading this resource. You can...

Students complete a simulated book order form for their class. In this book club activity, students budget and plan an order form for their fellow students, discussing why they chose specific books.

Learners will have fun creating a parachute to collect data with. They will construct the parachute in small groups, measure the materials, and create an observation sheet. Then they drop the parachute and make predictions about how long...
