Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...

Although there are only six questions on this chemistry handout, it makes a thorough review of solutions. Novices explain why a compound is not an electrolyte, identify types of compounds, and calculate moles, grams, and molalilties in...

For this solutions, suspensions and colloids worksheet, students use diagrams to show how particles are different in each of these mixtures. They also distinguish between characteristics of each of these types of mixtures and categorize...

In this solutions worksheet, students answer questions about the solubility of various substances in solvents such as oil in water and nitrogen gas in helium. They draw water molecules to show bonding between them and they diagram a...

In this solutions worksheet, students identify solutes and solvents from a list of solutions and they draw water molecules bonding to each other. They fill in the blanks with terms related to bonding in solutions, density of solutions...

Future chemists practice laboratory techniques by creating a monochloramine solution. The objectives are to use of dilution, 9concentration, and measurement skills and to prepare a solution that will be used in a water treatment...

What a great way to explore the scientific process! Learners conduct an experiment in which they use sugar and water to illustrate the concept of solutes and solvents. With this hands on approach, they are bound to remember what they...

Little chemists address whether or not you can get sugar back out of tea after it has dissolved. The PowerPoint itself simply walks them through the questioning process, considering different possibilities. The final slide settles on...

Chemistry apprentices unscramble seventeen general chemistry terms. At the bottom of the list, you will find online access to the solution. Print this resource out and have learners also write definitions for the different vocabulary...

Salts, solvents and hydroxides are listed and pupils will need to add information about a selection of electrolytes.  For a list of compounds, they indicate whether the solute particles will be ions or molecules and then the symbols...

In this transition metal worksheet, high schoolers are given equations of transition metals and their ions. Each equation shows the changes in colors of the ions when heat, salt or other substances are added to the metals.

Fifth graders design an experiment in which they separate mixtures. For this mixtures lesson, 5th graders define mixtures, solutions, solutes, and solvents. They watch a video, complete worksheets, and perform an experiment to separate...

Young scholars participate in a hands on activity simulating an oil spill. In this oil spill lesson plan, students conduct an experiment about an oil spill, discuss how it would affect the environment and provide solutions to prevent oil...

Students investigate common household items and classify them into types of matter. In this matter instructional activity, students group given items into categories based on their characteristics. They also complete a concept map about...

In this classifying matter worksheet, students create a concept map to show the relationships between given terms such as elements, matter, substances and solutions.

In this pH activity, students describe the pH scale and explain the initials "pH." Students classify solutions as acidic, neutral, or basic. Students name compounds as acids or bases. This activity has 3 short answer questions and 5 fill...

In this solutions worksheet, students solve twelve problems including calculating products made in reactions, determining limiting reagents, calculating molarity of solutions, determining percent composition, and finding volumes and...

In this graphing solutions worksheet, 9th graders solve 13 various types of problems. First, they find the solution of each systems by graphing on the coordinate plane provided. Then, students solve each systems of equations...

Students decide where to locate ice cream stands in a town so that no one has to travel too far to buy a treat. The problem-solving strategies for this problem give students a chance to decide what makes a solution satisfactory.

Young scholars measure salt content in water. They determine salt content of four samples using a hydrometer.

In this chemical reactions worksheet, students determine the reaction rate for various reactions, write balanced equations, create graphs showing the reaction over time, and calculate the activation energy and potential energy. This...

Students conduct a pH probe of various household products including both bases and acids. In groups, they use litmus paper to test such liquids as amonia, vinegar, and detergent to discover which are acids and which are bases. Finally,...

In this mixtures worksheet, students brainstorm the problems and possible solutions of how to separate mixtures. This worksheet is a graphic organizer.

Students explore conductivity and productivity in aquatic systems.
