Using toothpicks, straws, or tubes of rolled up newspaper, learners create 3-dimensional models to illustrate the basic structure and function of the cell membrane, and place an object inside to repre

Learners test their "light-smarts" by playing a game called "Light Quest!" The game board represents an atom and each player represents an electron that has been bumped into the atom's outer unstable

In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!

In this activity, learners make a black box device that serves as an excellent analogy to Rutherford's famous experiment in which he deduced the existence of the atomic nucleus.

In this activity, learners construct a cereal chain as a model of how proteins are made in the cell.

This simple and engaging astronomy activity explains nuclear fusion and how radiation is generated by stars, using marshmallows as a model.

This paper describes a working-model demonstration of Ernest Rutherford's 1911 experiment about the nature of atoms.

Working in small groups, learners receive a written scenario regarding a bacterium with a certain goal it must carry out.

In this activity, learners use colored candy to represent subatomic particles and make a model of an atom (Bohr model).

Learners make a mobile model of a carbon atom using clay, wire, and pipe cleaners.
