Discover the properties and purpose of chemical solvents. Continuing with the theme of shampoo ingredients, the 10th lesson of this 24-part series investigates the choice of solvents in shampoos. Through their exploration, they learn how...

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...

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...

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...

Smoking, alcohol, drugs, and solvents are the topic of this informational presentation. The causes, effects, and health issues that arise from illicit drug use are all covered. While this appears to be a learner-driven presentation, it...

This lab activity is geared toward experienced chemistry learners, in particular, those who are familiar with organic chemistry. They will create a synthetic elastomer  and then make observations and measurements of its different...

For this mixtures worksheet, students 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 chromatography worksheet, students are given markers, filter paper and a solvent to separate the pigments found in each marker. Students create a chromatogram for each marker.

Students investigate factors affecting the rate of solubility. In this rate of solubility lesson plan, students experiment by crushing, heating and cooling solutes and solvents to see how the solubility is affected. For each situation,...

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

For 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 learning exercise, 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...

In this rate of solution worksheet, high schoolers determine how quickly a solute dissolves in a solvent by testing one independent variable such as temperature, particle size or the amount of stirring. Students design their experiments...

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

Students investigate the pigments in Magic Markers using chromatography. In this paper chromatography lesson plan, students use absorbent paper and mark the strip with a Magic Marker. They place the strip in a solvent and observe the...

For this mixtures worksheet, students experiment with different amounts of solutes and solvents to make solutions. They observe color changes and look for chemical and physical changes in the test tubes. Students answer 5 questions and...

Students identify various kinds of paints by using the scientific method.  In this solvents instructional activity students collect data and identify paint samples while working in teams.

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...

Explore the mathematical relationship between a solvent and solute. Learners use technology to measure the cooling patterns of a solvent with varying concentrations of solute. Through an analysis of the data, pupils realize that the...

High school chemistry class members become "detectives for a day" and use the concept of paper chromatography to analyze a note left at the scene of a crime. Pupils test the ink on the note with a solvent, such as isopropyl alcohol, to...

Without water there would be no life on this planet. Biology learners find out why by reading this handout. Create a worksheet of questions to answer after the reading. Follow it up with quick demonstrations or laboratory activities that...
