Mixtures
Students experiment with solutions. In this mixtures and solutions science instructional activity, students work in groups of three to perform an experiment. Students place a sugar cube in three glasses, and observe and record the...
Curated OER
Straw Chromatography
Students 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.
Curated OER
Choices Make A Difference
Students are explained that wastewater treatment plants are regulated as to the quality of water they may discharge into our rivers and canals. They are explained that wastewater treatment plants clean many pollutants out of the...

Does the Introduction of Pesticides and Fertilizers Alter an Aquatic Ecosystem?
Students conduct an experiment using a small sample from a local water source. They introduce fertilizers and pesticides, separately, and carefully examine the results in their simulated aquatic ecosystem.
Curated OER
Straw Chromatography
Learners separate food coloring using liquid chromatography. In this chemistry lesson, students explain the effects of different solvents on the rate of separation.
Curated OER
Chlorophyll
Students use thin layer chromatography, TLC, to separate various pigments found in plants.
Curated OER
Distant Relatives
Students investigate observations between widely separated populations of anchialine cave fauna. In this biogeography instructional activity students discuss theories that could explain the given observations.
Curated OER
Rate of Solution
Eighth graders determine the amount of agitation necessary to dissolve various sized sugar particles. This task assess students' abilities to collect, organize, and interpret data, create appropriate graphs, predict future events based...
Curated OER
Experimenting with Physical Changes
Fourth graders explore physical changes. They discuss that physical change is a change in size, shape, or state of matter of a substance. Students explore what change takes place when two substances can dissolve each other. They observe...

Flower Pigments
Pupils experiment with Thin Layer Chromatography to separate pigments found in flower petals.
Curated OER
Food and Fiber: Helping the Environment and You
Fourth graders explore the many uses of corn-based products and the importance of water resources. They consider how biodegradable products help to keep water clean. They perform experiments to observe how corn pellets dissolve while...
Curated OER
Sedimentation
Students are introduced to the various types of sedimentation. In groups, they define the term and research what causes it to happen. They compare and contrast the different types of sedimentation and research how it occurs off of Cape...

Water, Solutions, pH, and Buffers
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...
Curated OER
Solutions, Suspensions, & Colloids Lab
In this solutions, suspension and colloid activity, students complete a lab experiment in order to determine if a given mixture is a solution, suspension or colloid. They are given six vials and they record their observations of each and...

Demonstration of Water Pollution
In this teacher-led demonstration, your young environmentalists will observe and record how different types of water pollutants look when they are combined. From here, individuals will develop a hypothesis on how the water can be...
Curated OER
Chalk Chromatography
Your chemistry class is sure to love this experiment on column chromatography, as demonstrated with chalk sticks and felt tip markers. Pupils use sidewalk chalk (another inexpensive form of chalk stick) to demonstrate adsorption and the...

States of Matter: Making Ice Cream
Who knew that learning about the states of matter could taste so sweet? This fun hands-on lesson captures the attention of learners as they use what they know about solids, liquids, and gases to create their very own batch of ice cream.
Curated OER
Conservation of Mass
High schoolers conduct an experiment to compare the total mass of products to the mass of reactants. In this conservation of mass lesson plan, students devise an experiment to show that matter is neither created or destroyed in a...
