Gumdrop Atoms
Students use gumdrops and toothpicks to make lithium atom models. Using these models, they investigate the makeup of atoms, including their relative size. Students are then asked to form molecules out of atoms, much in the same way they constructed atoms out of the particles that atoms are made of. Students also practice adding and subtracting electrons from an atom and determining the overall charges on atoms.
Students investigate the makeup of atoms
Engineers and scientists have the ability to not only change one element into another, but also to make elements that do not already exist in nature. The last few elements on the periodic table are all human-made. Engineers can use these elements to serve a specific design purpose, such as making a stronger metal alloy for a bridge or building, or designing a new medicine. All types of advanced technologies are possible because engineers study the physical and chemical properties of the atom to alter their natural properties.
After this activity, students should be able to:
- List the basic components and structure of the atom.
- Identify the electrical charge of an atom and its subatomic particles.
- Explain how engineers use their knowledge of atoms to create new technologies.
