How Can We Find Out What Is in Water?
Using paper chromatography, water watchers discover that several substances might be dissolved even though they aren't visible. In this case, you will prepare a mixture of three different food colorings for them to experiment with. A...

Colors Collide or Combine?
As part of a unit investigating the dissolving of M&Ms® candy coating, this lesson plan examines whether or not the different colors combine. There are no new concepts revealed in this particular lesson plan, but learners will see...

Chromatography - Chemical Separation of Colors
Third graders use the scientific method as they separate the colors used in ink. In this chromatography instructional activity, the teacher introduces students to how chromatography is used in several careers, then students perform an...

Temperature Changes in Dissolving
Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

The Formation of Solutions
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...
Curated OER
Mixtures
In this chemistry worksheet, students 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.

Mixtures and Solutions: Paper Chromatography Experiment
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...
Perkins School for the Blind
Mixtures and Solutions
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...

Investigating the Line
Note that this lesson is best paired with the preceding lesson in the unit. In that lesson, elementary physical scientists observed that the color coating of M&Ms® candies do not mix when dissolved off of the chocolate surface. Now...
Curated OER
Reversible/Irreversible changes
Students observe an online activity where they see some solids dissolving and some not dissolving. For this dissolving lesson plan, students learn which solids will dissolve, melt, and which won't. They will also see which effects are...
Curated OER
Mixtures
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.
Curated OER
Seashore Explorers
There are three separate lessons within this resource that can be used together, or that can each stand alone. In the first, five simple activities allow junior scientists to examine the amazing properties of water. In the second, they...
Curated OER
Solids and Water
Students investigate mixtures made of water and familiar solid materials. They observe and discuss the changes that occur immediately and set the mixtures aside for a day. Finally, students observe the mixtures, note changes, and graph...
Curated OER
Marvelous Mixtures
Fifth graders design an experiment in which they separate mixtures. In this mixtures lesson, 5th graders define mixtures, solutions, solutes, and solvents. They watch a video, complete worksheets, and perform an experiment to separate...
Curated OER
Color Burst
Students gain experience in asking questions and conducting inquiry by exploring the separation of colors in water and other solvents; to communicate and share findings of student investigations.
Curated OER
Solutions and Suspensions
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...
Curated OER
What is a Solution?
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.
