Using the physical science book – they need to be able to complete the following objectives in essay format.

Chapter 12:

The higher the temperature, the more the atoms "bounce around."
This bouncing around is the atoms in constant motion.
The constant movement is in the same area and they only bounce back and fourth.

Chapter 13:

(1)Atoms are made of three smaller particles known as protons, neutrons, and electrons. Electrons have an electric charge, usually found outside the nucleus.

(2)The Bohr Model was devised by Niels Bohr, a danish scientist. The model depicts an atom as a small, positively charged nucleus sorrounded by electrons
that orbit the nucleus similar to that of the solar system.

Chapter 14:

Properties that you can measure or see through direct observation are called physical properties. For example, water is odorless, colorless, and liquid at room temperature.
Physical changes are reversible. You can undo melting, boiling, or bending, usually. Chemical properties can only be observed when one substance changes into a different substance. For example, if you leave an iron nail outside, it will rust. A chemical property of iron is that it reacts with oxygen in the air to form iron oxide (rust).

The periodic table is organized by the type of elements. Non metals are green, metals are yellow, metalloids are blue, and than there are outlines. Blue outlines are transition elements, red outlines are main group elements.

Identify metals, semi-metals, and nonmetals on the periodic table

Differentiate the electrical and thermal conductivity of metals and nonmetals

Define periodicity and discuss examples

Predict properties of an element based on its position on the periodic table
