Matter & Subatomic Particles

Scholars use sorting cards to try to define a pure substance versus a mixture. Risk becomes reward as they observe the differences and create a flowchart sorting matter into mixtures and pure substances (elements and compounds).

Seventh graders examine the different types of pollutants. In this environmental science lesson, 7th graders observe particulate matter under a microscope. They explain how these can affect once health when breathed in large quantities...

Atomic bombs harness the power in the nucleus of an atom, creating devastating power and damage. Classes review parts of an atom by charging a piece of plastic and holding it near their fingers, discussing what is happening and why....

In this atom worksheet, chemists learn how to determine the number of protons, neutrons and electrons in an atom using the atomic mass and atomic number. They complete a chart of the subatomic particles and use marbles to represent...

For this chemistry worksheet, students learn about matter, including atoms, electrons, protons, neutrons, compounds and chemical properties. They use this information to answer the 10 questions on the worksheet. The answers are on the...

Take an energetic ride through the phase changes of a water molecule in a compact activity. Young scientists learn about the phases of matter and discover the role of thermal energy in governing phase changes while watching a short...

Middle schoolers define vocabulary related to the parts of the atom.  In this matter activity, students navigate the web to find the structure and the forces that affect atoms.  Middle schoolers complete an experiment with...

Did you know that jumping spiders sometimes wear water droplets as hats? A seventh grade science lesson introduces the concept of what makes up water: tiny molecules that are attracted to each other. Starting with a...

Students research the affects that particulate matter has on the quality of our air and our health. Students analyze a streaming video on air pollution and complete an internet research assignment to find ways to reduce particulate...

Students create a definition of matter. For this physical science lesson, students work in pairs to sort items printed on cards into several categories (matter, non-matter, and unsure) and agree on a definition of matter.
