Encourage your classes to be laundry helpers! Learners explore the chemistry of stain removal with a lab investigation. By identifying the components of the stain, they identify the most effective solute for its removal.

Middle school scientists bathe in Bikini Bottom with SpongeBob and friends. They define steps in the scientific method. They identify independent variables, dependent variables, and the control for science experiments being carried out...

Students use the net they make to dip macroinvertebrates at or below the surface. The flat side of the net allows pressure on the substrate so that organisms do not escape under the net. Two students hold onto the handles and submerge...

In this polymer worksheet, students make two types of cross linked polymers and they test their physical properties. These include their response to agitation, stretchability, viscosity, and resilience.

Students use short-chain polymers and borate ions to produce cross-linked polymers in the lab. In this cross-linked polymer lesson plan, students produce polyvinyl acetate slime and polyvinyl alcohol slime and test their physical...
