Learners explore matter by conducting an in class demonstration. In this liquid mixture lesson, students identify the difference between a solution in which a solid dissolves into liquid, and a suspension where the solid doesn't dissolve...

In this solutions, suspension and colloid learning exercise, students complete a lab experiment in order to determine if a given mixture is a solution, suspension or colloid. They are given six vials and they record their observations of...

Eighth graders examine different solutions.  In this solution material lesson plan students complete a lab activity and several worksheets. 

In this aqueous solutions worksheet, students will explore the characteristics of solutions, including the ability of different compounds to dissolve in the solutions. This worksheet has 10 true or false statements and 8 short answer...

In this solutions worksheet, students determine how the amount of solute in a given amount of solvent effects the concentration of the solution. Students calculate the molarity of solutions. This worksheet has 7 fill in the blank, 3...

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

How well can your class concentrate on solutions? Scholars use colorimeter absorption to explore a starch concentration calibration curve. They add iodine to different starch solutions to see how the concentration of the solution changes.

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

In this solutions worksheet, students compare situations that increase or decrease the solubility of a solute. Students describe how surface area, stirring, and temperature can increase the rate of dissolving a solute. This worksheet has...

In this solutions worksheet, students determine concentrations of reactants at equilibrium. Students describe the effects of adding reactants have on the solubility of a compound. This worksheet has 5 problems to solve.

Students evaluate the relationship between biodegradable waste and dissolved oxygen in water.  In this biodegradable wastes lesson students complete a lab activity in groups then analyze their results.

In this solutions worksheet, students review types of solutions, concentration and saturation of solutions, and suspensions and colloids. This worksheet has 10 fill in the blank, 7 multiple choice, and 6 short answer questions.

In this solutions worksheet, students calculate molality and mole fraction. Students define colligative property and determine what affects the solubility of gas in solvents. This worksheet has 2 short answer questions and 9 problems to...

Learners observe that movement of a solute in the solvent increases the rate of dissolution. They demonstrate that when the solute is broken into smaller pieces it dissolves faster.

Students investigate reaction rates.  In this seventh or eighth grade mathematics lesson, students collect, record, and analyze data regarding how the temperature of water affects the dissolving time of a sugar cube. Studetns...

Students identify diffusion and its processes through experimentation and calculations. They also use a CBL and conductivity probe to measure the conductivity of various solutions and study the effect of concentration gradients on the...

Can your scholars solve the mystery of why salts dissolve? A virtual workbench allows them to experiment with temperature and solubility with no solution prep and no post-lab clean up! Users determine the solubility of a variety of...

In this water and solvent worksheet, students answer 20 questions about solutes, solvents, polarity in molecules, and the characteristics of water as a solvent. Students answer 3 questions about the lab they completed using temperature...

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...

Learning ... how sweet it is! A hands-on lesson uses colored candies to demonstrate how positive and negative charges interact. Pupils use different types of liquids and watch as the color from the candies spreads—or doesn't. 

In this determining concentration instructional activity, students are given the equations to find the concentration of a solution in grams per milliliter, to determine the concentration in parts per million, to determine percent mass...

In this freezing point worksheet, students determine the freezing point of solutions at different concentrations. This worksheet has 9 problems to solve.

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