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 instructional activity investigates whether or not the concentration of sugar in the solvent affects the dissolving rate. Consider having older science learners...

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...

Learners model solutions with beakers of colored glass or plastic spheres. In this solutions instructional activity, students use beakers of colored spheres to represent pure substances. They mix the spheres to demosntrate solutions....

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...

Students evaluate pH levels through a solubility experiment. In this pH levels lesson, students list characteristics of acids and bases. Students complete their own pH level experiment. Students go to the GEMS Alien Juice Bar website to...

Explore the importance of a concentration gradient in the rates of dissolution. Using the ocean ecosystem, learners study rates of dissolution around coral reefs. A hands-on experiment helps individuals discover the effects of changing a...

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

This in-depth organic chemistry lab walks learners through an investigation of the effect of initiator concentration on the resulting molecular weight of polystyrene. It is important that you use this lesson with experienced chemistry...

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.

Students examine why diffusion and osmosis happen in an egg cell.  In this diffusion lesson students demonstrate a semi permeable membrane.

Learners 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 populations...

Don't be shocked when your class has a blast making their own batteries! Science scholars examine a dry cell battery, then design and construct a wet cell battery. The activity guides them through the parts of a battery, the variables...

Learners become acquainted with the principles of liquid chromatography and construct a liquid chromatography column. Students also investigate the effects of different solvents and solvent concentrations in the separation process.

Students make dilutions using dulution trays. They keep track of their dilutions and the concentrations of solute, to parts per million (ppm) and parts per billion (ppb), in order to have an comprehension of the terms. Students make...

Learners predict the product of chemical reaction using the solubility rules. In this chemistry lesson, students balance ionic equation. They perform a lab to check if their predicted products are correct.

Students examine solubility and the significance of water.  In this aqueous solution lesson students complete a lab activity on soil profiles.

Learners use chromatography to separate substances in Kool-Aid, Crayola markers and leaves. For this chromatography lesson plan, students make chromatograms to separate substances in a mixture through absorption. Learners find the Rf...

Young scholars explore chemical cahnges and the effect of temperature on chemical mixturees, They make observations of the behavior and appearance of certain chemical mixtures and reactions.

High schoolers separate food coloring using liquid chromatography. In this chemistry instructional activity, students explain the effects of different solvents on the rate of separation.

Learners explain the process of polymerization. In this chemistry lesson plan, students produce carboxylesterase in the lab. They test its effectiveness in removing the by-product odor.

High schoolers explain the basic concepts of polymerization. Students participate in a lab to create a crude preparation of carboxyl esterase and test its effectiveness in reducing the residual monomer in an emulsion such as paint.

Students initially engage in online research and consult print materials to identify a compound to produce. Once a selection has been made, individually, students conduct lab experiments to isolate substances. The end product is a...
