High schoolers explore the concept of molecular modeling and differentiate between saturated and unsaturated compounds. In small groups, they identify molecular formulas, complete a chart comparing alkanes, alkenes, and alkynes, and...

Students are able to identify, create, and evaluate three kinds of sentences: simple, compound, and complex. They are able identify the purpose of various sentence types: declarative, interrogative, imperative, exclamatory, and...

Fifth graders investigate the nitrogen cycle and examine the concepts of decomposition and nitrification. Students participate in a class discussion about the creation of waste and ammonia compounds, then using nitrogen cycle cut-outs...

In this chemistry worksheet, students identify the name and abbreviation of the SI unit for mass, length, time, electric current, and temperature. Then they give the abbreviation for each of the units listed and describe what they are...

In this earth and beyond worksheet, students answer short answer questions about the atmosphere, the chemical compounds in Earth's atmosphere. Students visit different websites to conduct research of the discoveries of the scientist who...

Students interview the chemical elements. They research information about their element, such as: stable isotopes, valence electrons, number of subatomic particles. They create a yearbook page for their element, and a format to present it.

For this molecules worksheet, students research a substance that is made up of molecules with two or more elements. Students name the substance, write a short description of the substance, and draw a picture that illustrates the substance.

Fifth graders investigate the nature of matter and of the scientific processes associated with them in this series of lessons.
