Mixtures and solutions are different; one can be separated fairly easily and the other cannot. This hands-on experiment was written specifically for learners with visual impairments or blindness. They will use lemonade and trail mix to...

Here's a sweet lesson to explore solutes and solvents. Using candies and water, learners observe properties of parts of the solution as the candies dissolve. They then modify the setup and note variations in the solution. 

It's time to test observation and dissolving skills! After investigating the process of dissolving in previous lessons, pupils see if they can use their dissolving skills to identify substances. They dissolve known and unknown substances...

Why does like dissolve like? While in many cases opposites attract, the same cannot be said for chemistry! Solution scholars take an up-close look at the dissolving process with a customizable interactive. The resource allows users to...

What common chemical includes safety warnings for being harmful if swallowed or inhaled, causes serious eye damage, and needs to be cleaned up immediately if spilled on the floor? Surprisingly, the dangerous chemical turns out to be...

Why does some ink bleed through paper, and other ink doesn't? Practice some paper chromatography to separate the colors from a pen with an interactive experiment for middle and high schoolers. Learners use a variety of solutions to track...

In this dissolving solids and gases worksheet, students learn that the process of dissolving gas is opposite of the process of dissolving solids. Students answer 3 critical thinking questions about dissolving gases and solids in solutions.

In this solutions instructional activity, learners solve twelve problems including calculating products made in reactions, determining limiting reagents, calculating molarity of solutions, determining percent composition, and finding...

In this solutions worksheet, students review the most commonly used solvent, give examples of an emulsifying agents and alloys, and use solubility curves to answer questions. This worksheet has 11 fill in the blank, 6 short answer, and...

In this solutions worksheet, students soak a pipe cleaner in hot water and a supersaturated solution of 20 Mule Team Borax. Students leave their pipe cleaner in the solution for 30 minutes and then observe. They put it back in over night...

In this solutions worksheet, students complete a three step procedure and record the dissolving time of candy. Using their data they create a graph and answer 4 analysis questions.

For this mixtures, solutions and matter worksheet, learners are given 12 terms and they cut out 12 definitions to match with the terms. Topics include types of mixtures, types of matter such as atoms, molecules and compounds and solutions.

When no more solute can be dissolved into a solvent, the solution has reached saturation. The interactive simulation allows learners to manipulate a solution in order to measure its concentration. The amount of solvent, the amount and...

In this mixtures worksheet, high schoolers read about mixture and what determines if a solute dissolves in a solvent. They answer three questions about solutions and determine from a list of compounds which are soluble in water.

In this solutions worksheet, students read about solutions, solutes, and solvents. Students compare solutions with mixtures that are not solutions. Then students complete 10 fill in the blank, 12 matching questions, and 10 terms into a...

In this solutions worksheet, students read about the characteristics that define a solution such as the solvent and the solute and the homogeneous mixture. They are given a chart with the differences between solution, colloids and...

In this aqueous solutions instructional activity, students will conduct an experiment to determine the solubility of different common kitchen items. Students then complete 3 short answer questions.

In this volumetric analysis worksheet, learners follow the given directions to prepare a standard solution of sodium carbonate. They later use the prepared solution in a laboratory practical.

In this activity for making standard solutions, learners read about making a standard solution and perform the three background calculations necessary to make one. Students then make a solution by weighing a given substance, adding it to...
