Lego Atoms and Molecules: Chemical Reactions
Show young chemists what a chemical reaction looks like with two parts of a hands-on experiment. First, learners conduct a wet lab where they observe the reactants (baking soda and calcium chloride, with phenolsulfonphthalein) before,...
Tech Museum of Innovation
Analogous Models
What goes into a museum display? A secondary-level STEM project prompts groups to design a museum display for the Tech Museum of Innovation. They create an analogous, interactive model illustrating a science concept to complete the lesson.

What Determines and Limits an Atom's Mass?
Provide learners with the tools to further understand nuclear energy and isotopes. Young chemists investigate the components of an atom's nucleus, use symbols to represent various isotope forms, and use the percent abundance of an atom's...
American Museum of Natural History
Atomic Mobile
Structure an activity around atoms. Learners use their knowledge of the parts of atoms—the protons, neutrons, and electrons—to build a model of a carbon atom. Scholars create a nucleus by using clay balls to represent the protons and...

What do Atoms Look Like?
In this atom worksheet, students answer 31 multiple choice questions about the structure of atoms, the periodic table, the reactivity of elements, orbital diagrams and the families of elements.
Shelby County Schools
Atomic Structure Worksheet
Teaching young scientists about atoms is no small task, but this series of worksheets will make it a little easier. From creating and labeling Bohr models, to identifying information provided in the periodic table of elements, this...

Atomic Structure and Ionic Bonding (A Visual Approach)
Using toothpicks, marshmallows, and round colored sticky dots, physical science enthusiasts build models of an atomic nucleus. In this eighth grade chemistry lesson plan, they play an atom-naming game with the models that they have...
Curated OER
Hydrocarbons
Making models is always memorable. In this activity, physical science starters examine the structure of hydrocarbons using marshmallows, raisins, and toothpicks. They even act as atoms themselves and link arms to represent covalent...
