In this solutions worksheet, high schoolers 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...

If you are not part of the solution, then you are part of the precipitate. The presentation covers solutions, suspensions, solubility, dissociation, and acid/base reactions. This is the 19th lesson in a series of 26.

What happens when solids are added to liquids? After reading an informative paragraph about solutions, learners answer six true/false questions regarding solutions, and what substances will dissolve into liquids they are mixed with. A...

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. 

From types of rocks to types of weathering, learners gain knowledge on minerals, composition of soil, and the effects of weathering on Earth.

In this solutions worksheet, students will review 9 vocabulary words associated with solutions including mixtures, elements, compounds, and dissolving. Students will complete a word puzzle in this worksheet.

In this solutions activity, students compare different types of solutions and distinguish between the solvent and solute in a solution. This activity has 7 matching and 10 short answer questions.

Heat up your lessons on boiling points. The resource provides a three-part activity: first, groups find the boiling point of solutions; second, they create boiling point curves for salt and sugar solutions; and third, they mix a solution...

For this word problem worksheet, students read mixture problems and write equations to solve the problems. This two-page worksheet contains six problems, with answers.

Students 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.

Fifth graders, in groups, distinguish between mixtures, solutions and suspensions.

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...

Avoiding lab safety rules will not give you super powers. The instructional activity opens with a demonstration of not following safety rules. Then, young chemists practice their lab safety while finding the mass of each item in a...

In this mixture worksheet, students fill two test tubes with water and add starch to one and salt to the other. They stir the solutions and observe their appearance. They answer four questions about their mixtures and determine if they...

In this solutions worksheet, students answer 18 questions about solutions, saturation of solutions, solvents and solubility.

In this mixture word problem worksheet, students read problems and determine the correct amount of mixture needed for the given situation.  This two-page worksheet contains 10 multi-step problems.  Answers are provided on the...

Elementary schoolers who are learning about filtration and mixtures could use this learning exercise to gain practice in filtering techniques. In it, they are asked how to manipulate a container in a way that would lead to properly...

High schoolers classify different mixtures. In this mixtures lesson plan, students determine samples to be suspensions, colloids, or solutions and compare homogeneous and heterogeneous mixtures.

In this solutions learning exercise, learners 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...

Learners investigate different fruits and vegetables for the presence of sugars. In this sugars and Fehling's solution lesson, students test the juice from an onion and a lemon for the presence of sugar by adding Fehling's solution and...

Create a little scientific magic within your classroom! Learners mix powders and liquids and identify chemical reactions. Based on the reactions, individuals determine the identity of various powders.

Precipitation reactions are always interesting. How about one that forms a precipitate using a gas? Chemists of any age will enjoy this twist on a standard solubility lab. Partners observe the lack of interaction between sodium...

Investigate the amazing ability of plants to filter contaminants from water with this series of in-class demonstrations. After placing six small, potted plants in plastic cups, different solutions and mixtures are poured into them that...

Elements, to the rescue! Scholars first review the periodic table, and then learn about the first 20 elements and their properties and uses in the fourth of six lessons in the Mixtures and Solutions unit. Applying their newfound...
