Modeling Atoms with Food

Modeling Atoms with Food | Science Fair Projects | STEM Projects
Have you ever wondered what an atom looks like? Now you can find out by building models of them with food! You'll use dried pinto beans, dried kidney beans, and dried rice to represent protons, neutrons, and electrons.


The hypothesis is that by building models of atoms with food, students will gain a better understanding of how atoms work.

Method & Materials

You will draw 5 different element cards, get 5 paper plates, glue, and small cups of dried pinto beans, dried kidney beans, and dried rice. Then, you will use the pinto beans as neutrons, the kidney beans as protons, and the rice as electrons to build a model of each atom, ion, or isotope shown on the card.
You will need a bag of dried pinto beans, a bag of dried kidney beans, a bag of dried corn kernels or brown rice, Elmer's glue, paper plates, a periodic table, a list of elements, ions and isotopes, and element cards.


After building the models, students will identify the atom or variation of the atom constructed on the back of the paper plate. This experiment will help students gain a better understanding of how atoms work and the different variations of atoms.

Why do this project?

This science project is interesting and unique because it allows students to gain a better understanding of atoms by building models of them with food.

Also Consider

Experiment variations to consider include building models of different elements, ions, and isotopes.
