Students experiment to create a plastic solution. In this science instructional activity, students use sodium borax and polyvinyl alcohol to create their solution, then identify, discuss, and chart observations on the end product.

Students participate in a laboratory investigation in which they observe the effect of temperature and pH on enzyme activity. Students also examine exposure to heavy metal ions and the effect that may have on enzyme activity.

What a web we weave. Pupils use yarn as the primary resource to create a web depicting the intricacies of a salt marsh ecosystem. They participate in a question and answer session, which leads to an in-depth facilitated discussion...

In this science worksheet, learners explore the learning outcomes for a unit on chemical reactions. Students define 60 vocabulary words and answer a list of questions for each topic.

Seventh graders observe that heat is produced when two substances are combined. They brainstorm how, and then experiment to find out which of two chemicals created the heat.

In this recognizing different types of changes worksheet, students answer questions about such things as reversible change, irreversible process, climatic change, filtration process, physical change, and change in the state of a...

In this atomic fingerprint learning exercise, students read about the Bohr model and electrons changing energy levels and emitting energy. They answer questions about the atomic spectrum and the fingerprints for specific atoms.

High schoolers examine hydrothermal vents. In this ocean lesson, students identify changes in physical and chemical properties of sea water caused by hydrothermal vents.

Students describe the history of materials. They use the kinetic (particle) theory to explain changes of state in matter and trace the flow of heat during changes of state and chemical changes.

In this chemistry science worksheet, students identify the parts of a chemical reactions. Students name the major particles of the atom. Students apply knowledge about the atom, theories, and models.

Young scholars investigate how water changes state. In this water instructional activity, students observe, measure, and describe water as it changes state. This instructional activity includes extensions which can be accessed via the...

Third graders explore forms of matter through reading, hands-on science activities, and research using the Internet. Students create a booklet, directions given, that they title and decorate, to later serve as a review visualization...

In this chemical reactions worksheet, students fill in 12 blanks with the appropriate terms related to chemical reactions. They also indicate if 4 statements are true or false and match 7 words with their descriptions. Students complete...

Eighth graders conduct an experiment that analyzes the physical and chemical characteristics of various water samples. They discuss the procedures and safety concerns for the water test, and test their water samples to determine if they...
