Students must pick an atom to represent with a model. I tell them that it must be 3D, colorful, unique, creative, neat, and accurate. I have had some great ones: cakes, fish bowls, hamster cages, fruit, etc... atoms, periodic table, elements

In this activity student draw the atomic structure of the first fourteenelements as balanced atoms (same number of protons, newtrons, electrons). Students complete a data table for each element and fill electrons in energy levels according to Borh's model... Atom structure drawing activity alfonso

History of Atomic Theory.
The purpose of this powerpoint lesson in science along with grocery food items will help and illustrate to students how the atomic theories have evolved and changed over time. Grocery food items you should purchase is a bunch of grapes (Greek model), a jawbreaker (Dalton model), chocolate chip cookie dough (JJ. Thomson model), avacado (Rutherford), onion (Bohr model) and Hostess cream filled cupcake (Electron Cloud model).

As you use this powerpoint presentation with each 1-2 minute video clip then follow up with the food item to illustrate each key feature.

Greeks stated that an atom is indivisible and that each is the same. If you model with a bunch of grapes -that when you pluck each grape off, when you get to the last grape (atomos) that last one is indivisible so if you cut it it is no longer the same atom.

Dalton stated that is an atom is a solid sphere so model that with a jaw breaker.

JJ Thomson used static electricity and discovered that an atom is a solid sphere and the sphere is positivily charged which is the cookie dough and the negitively charged particles, the electrons (chocolate chips) are embedded throughout. If you put your finger into the atom the odds are that you will hit an electron, an chocolate chip.

Rutherford agreed with the previous models yet there is a solid center called the nucleus which is the avacado pit. He also discovered that the atom is mostly empty space, the fleshy part of the avacado so that things, radiation from the gold foil experiment, can pass through it.

Bohr model uses the onion and he discovered that electrons move around the nucleus in fixed pathways, the onion layer when the onion is cut in half it looks like the planets move in pathways. This was an improvement on JJ's model of electrons randomly spread out in the atom.

Electron Cloud model is illustrated by the cream filled cup cake. The electrons are found specifically in the cream layer, when cut in half, and the other electrons are found in the outer cake of the cupcake. Instead of moving in a fixed orbit like the Bohr-onion example the electrons are moving around anywhere but within their cream layer and the other electrons moving around in their cake layer. atom, atomic history, atomic theory, atomic model, models of the atom

In this activity student complete the atomic structure of four elements chosen by the teacher as balanced atoms (same number of protons, newtrons, electrons) using pieces of paper of three colors (one color for each sub atomic particle). Students complete a data table for each element and fill electrons in energy levels according to Borh's model... Atomic Structure Activity -modeling atoms using hole punch alfonso

This PowerPoint covers the structure of the atom and uses videos as a starting point. The presentation is designed to illicit feedback from the students after watching the video. Following the presentation is a 10 question quiz. The presentation covers the following: Subatomic Particles Protons, Neutrons, Electrons Nucleus and it's composition Charge of Subatomic Particles Atomic Mass What makes atoms different from each other. Electron Cloud This is a good beginner or refresher before studying the Periodic table. Proton, neutron, electron, atom,
