The Periodic Table Of Elements: Drawing Atoms
All elements have an atom. An atom is the basic unit of a chemical element. Here is how to draw an atom.
1. Look at your element that you are drawing (helium)

2. Now, you need to find out the protons, neutrons and electrons. To do that, look at the element. The electrons and the protons are both the same number as the atomic number. The neutrons is the atomic mass - atomic number. (subtract).
3. Now you need to make a circle big enough to fit the number of protons and neutrons. Then you will make circles around that one circle. You need to put electon signs on each of those circles. Each level can hold: 2, 8, 18, 32.











The Periodic Table Of Elements
The Periodic Table of Elements is arranged in periods (side to side) and groups/families (up and down). There are metals, non-metals, metaloids and gases on the periodic table.

The 3 States Of Matter
  1. Solid- Has a definite shape and a definite volume. Molecules are close together
  2. Liquid- Has no definite shape but a definite volume. Molecules can spread apart.
  3. Gas- Has no definite shape or a definite volume. Molecules are spread apart.

Cell Parts And Functions
If the color is red, then the organelle is in both of the cells. If it is green, it is only in the plant cell, if the color is purple, then it is only in the animal cell.
  • Nucleus- Control Center
  • Nuclear Membrane- protects and supports the nuleus
  • Lysosomes- Digest Waste
  • Ribosomes- Produce Protein
  • Cell Membrane- protects and supports the cell
  • Cytoplasm- gel-like substance that makes up the body of the cell
  • Vacuole- Storage Area for food, water, and waste
  • Chloroplast- Found inside the plant cell; gives the cell its green color
  • Fat- found inside the animal cell; insulation
  • Cell wall- Found inside the plant cell; gives the plant cell its shape-Cellulose
  • Golgi (OR GOLGY) Body- stores energy and transports it
  • Mitochondria- Gives engery to the cell
  • Chromatin- Small materials found on the nucleus. Contain DNA
  • Endoplasmic Reticulum(ER)- Transports materials around inside the cell
