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...

Mix it up at a party as Sam and Zoe discuss heterogeneous and homogenous mixtures and solutions. Follow this film by allowing your class to put together individual snack foods to make their own mixture!

Now it becomes crystal clear why the unit is called Mixtures and Solutions. The fifth installment of a six-part unit explores mixtures and solutions. After viewing a demonstration on mixing pebbles with water, salt with water, and...

Do you separate your trail mix before eating it? Then you've been separating mixtures your whole life! Scholars model a contaminated soil sample using trail mix and estimate the percentage of each component. They consider how to clean up...

Here is a different approach to solutions: a learning exercise that has chemistry learners use words to describe them! This is an outstanding exercise that will stretch learners to show what they know. They answer questions comparing...

In this solutions, suspensions and colloids learning exercise, 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...

General chemistry classes practice spectroscopy. They grasp the relationships between wavelength, absorbance, and solution concentration. Additionally, they gain valuable practice using laboratory equipment such as burets and pipettes....

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...

Aqua regia, or royal water in Latin, is a solvent that can dissolve solid gold and platinum into a solution. Activity nine in a series of 36 allows classes to learn, through readings and answering questions, what a solution is and the...

Solve alcohol systems to find the right solution. The interactive allows pupils to manipulate the amount of a solution and displays the total amount in a mixture. Individuals determine the amount of each solution needed to make 15 liters...

In this chemistry worksheet, learners use the clues given at the bottom of the sheet to complete the crossword puzzle on mixtures. There are 18 clues to solve on the sheet.

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...

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.

What does size have to do with it? Learners analyze different mixtures, both homogeneous and heterogeneous, to discover the properties related to the size of their particles. The activity connects these properties to those of...

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 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...

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...

Sixth graders experiment with mixtures. In this chemistry lesson, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.

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...

In this mixtures, solutions and matter worksheet, students 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.

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

In 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.

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...

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...
