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...

From solid to liquid and then back again. Young scientists  dissolve salt in water and then evaporate the water while observing what happens to the solute. They use their observations to make predictions about other solutions.

Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....

One of water's claims to fame is as the universal solvent. Young physical scientists experiment to discover which materials dissolve in this special compound. You could never be more prepared for teaching this lesson than by using this...

To conclude a mini unit on the dissolving of M&Ms® candy coating, this lesson investigates whether or not the concentration of sugar in the solvent affects the dissolving rate. Consider having older science learners write their own...

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...

Ninth graders investigate the factors affecting solubility. In this chemistry lesson, 9th graders differentiate solvent and solute. They give examples of real world application of solutions.

Students experiment with solutions.  In this mixtures and solutions science lesson, students work in groups of three to perform an experiment. Students place a sugar cube in three glasses, and observe and record the different rates...

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...

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

Examine the chemistry of the laundry room! A thorough video explains the polarity and non-polarity properties of soap. The tutorial continues to explain the advantage of these properties in stain removal by showing the...

Exactly how environmentally friendly is your school? From the air fresheners in the bathrooms to the cleaning solvents used in the classrooms, young conservationists search the school grounds for sources of air pollution in...

Eighth graders examine different solutions.  In this solution material lesson students complete a lab activity and several worksheets. 

High schoolers model solutions with beakers of colored glass or plastic spheres. In this solutions lesson, students use beakers of colored spheres to represent pure substances. They mix the spheres to demosntrate solutions. They discuss...

Young scholars discover how temperature effects the solubility of solutes by experimenting with a range of temperatures. They develop skills for observing, inferring, measuring, comparing and contrasting.

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.

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...

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...

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,...

Learners experiment to determine which bottle of soda has more dissolved carbon dioxide. In this solutions lesson, students use the scientific method to test the amount of carbon dioxide in bottles of soda. They identify and explain the...

Students identify the different types of mixtures. They identify examples of solutions, suspensions, colloidal dispersions, and emulsions through a game and basic experiments.

Students design experiments examining the effects of various solutes on water. They record results on graphs explaining any unexpected consequences of their experiments and determine if their hypotheses were correct.

Students study flavinoids and how they exist in the plant kingdom.  In this pigment lesson students complete a lab activity to see how flavinoids move in substances then record their observations.

High schoolers obseve and compare molecular movement within water at various temperatures and of varying salinity. They discuss the movement of water on a larger scale which can affect the movement and concentrations of microbial...
