Fifth graders, in groups, distinguish between mixtures, solutions and suspensions.

An educational lesson allows young chemists to test the solubility of different types of salt at various temperatures. Groups create a graph using data from unsaturated, saturated, and supersaturated solutions.

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...

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...

Tiny particles can provide big learning opportunities! Middle school scientists explore the world of nanoparticles through reading, discussion, and experiment. Collaborative groups first apply nanotechnology to determine water...

Students develop a method to separate different types of mixtures. In this chemistry lesson, students model the steps in the scientific method. They perform the experiment and analyze data.

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...

In this solutions instructional activity, students calculate molality and mole fraction. Students define colligative property and determine what affects the solubility of gas in solvents. This instructional activity has 2 short answer...

There is not much information in this presentation. It serves more as a guide to direct the flow of your introductory chemistry lecture. Each slide displays a large title and a smaller phrase meant to explain it. For example, one title...

Experienced chemistry technicians use then layer chromatography to discover how much of a free compound is left after each rinse cycle. Where this could obviously be used as a practice with chromatography technique, it can also be used...

Some of kids' favorite toys are the products of science experiments. Scholars follow precise measurements to mix and create their own slime and Play-Doh. They observe the changing textures and the chemical reactions throughout the...

Finally, a chance for the class to play with their food! Allow pupils to simulate stomach acid with common foods, and introduce specific macromolecules into the mixture to explore characteristics of carbohydrates, lipids,...

Some chemical reactions produce heat, but what is really going on? Lesson focuses on the concept of energy changes, both exothermic and endothermic. Scholars perform multiple experiments, hands-on activities, and view videos of the...

Young scholars explore density, mixture and solutions in a reaction. In this chemistry lesson, students create their own chap-stick using ingredients they analyze for their chemical contents. They discuss measuring skills, melting points...
