Go to the phet Build an Atom simulation by clicking here. Choose the “Atom” activity (it will look like what we saw in class).
You should be able to run this simulation on your phone or a computer.
Make a copy of this google doc to write in and print your answers (you may also just write your answers/notes on notebook paper).
Feel free to explore the simulation outside of the questions. There are also games with this simulation if you are a fan of competition.
