Include this rubric in your folder.
Front:



Choose any element square in the Periodic Table
Reproduce the square on construction paper - Label atomic number, atomic mass, and atomic symbol.
Name the element and list number of protons, electrons, & neutrons
Left Top:

Atom – Define. Make a Bohr Model of a neutral atom from either period (row) 2 or 3. Name the element. Cut a nucleus out of construction
paper. Represent the protons with P = __ (+) to show positive charge and the neutrons with N = ___. Use colored markers on appropriate shells
using e (e–) signs to show the electrons with negative charge.
Left Bottom
1. Ion – Define. Make and label Bohr models of a positive and negative ion of the same element you made for your neutral atom. Use the same
process with a construction paper nucleus. Label protons (+), neutrons (n) and electrons (-).
Right Top:

Isotope – Define. Make Bohr Model of your neutral atom, but change the number of neutrons so it will be an isotope that is heavier or lighter.
Label which it is - heavier/lighter. Use the same process with a construction paper nucleus.
Right Bottom

Compound - Define and use shapes cut from construction paper to represent different atoms to create a model of a compound. Make sure the atoms
show they are chemically bonded
Back Top:

Mixture – Define and use shapes from construction paper to create a mixture

Pure Substance – Define and use shapes from construction paper to create a pure substance element and a pure substance compound.
Back Bottom

Define Physical & Chemical Change: Use construction paper to create a picture of a physical and a chemical change that you would experience
in your life.

Have Ms. Priest initial your choice of pictures before you begin

Do a before and after picture for each. You may not use ice and water as your example.
