Study Jams! Atoms: Protons, Neutrons, Electrons
What's smaller than a kiwi seed? Atoms! Basic atomic structure is detailed for beginning chemists in a light-hearted animation. Protons and neutrons are explained as part of the nucleus, and so are electrons that encircle the nucleus....
Curated OER
Mixtures, Solutions and Matter
In this mixtures, solutions and matter learning exercise, students are given 12 terms and they cut out 12 definitions to match with the terms. Topics include types of mixtures, types of matter such as atoms, molecules and compounds and...
Curated OER
Matter: Atoms and Molecules
Students investigate how information about the atom has been determined. In this atomic structure lesson, students draw what they think an atom looks like. They conduct Internet research about the types of atomic models and how...

Lego Molecules
Young scientists construct an understanding of molecular compounds in this hands-on science lesson plan. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common compounds.
Curated OER
The Atom
In this atom worksheet, high schoolers read about the structure of the atom including its subatomic particles and John Dalton's theory of the atom. Students also read about the differences between atoms, molecules and compounds. They...

Properties of Matter
A collection of ten slides reveals bright graphics and photos. Though the title is "Properties of Matter," the content is incoherent. You will find a couple of slides on chemical reactions, a few on the example of the S.S. Hindenburg...

What on Earth is Matter?
A somewhat strangely formatted slide show that contains multiple examples of matter types. The classification and state explanations given would be useful as practice of substance identification and the heating curve may prove to be...
