Bell work… I want you think of some things you’ve always wondered

about…things in the universe or on Earth, anything at all, that you don’t understand or would like answered.

Then write it on the post-it notes provided (if you want more than the 2 provided I will give them to you)

Be creative! When I say anything, I mean anything!

Examples…

Why is the sky blue?

How do we see colours?

Why is light the universal speed limit?

What is a virus?

What is a cloud?

What is a black hole?

When will the Earth cease to exist?

What happens when 2 galaxies collide

Tell me what you know about the periodic table. Any trends, names, anything…

Diagnostic from grade 10

I want you to answer the following review sheet to the best of your ability.

It is meant to be an assessment for yourself and for me to see how much you remember from grade 10 science

IT IS NOT A TEST --- NOT WORTH MARKS

I’ll give you 20 min to finish this then we will take it up

Take up the diagnosis

Sodium

# protons: The same as the atomic Number (11)

# electrons: The same as the protons (11)

# neutrons: Mass Number minus atomic number (12)

Sodium

# Electron Shells: look at the period number, that’s your answer. (3)

# Valence Electrons: Look at its family number and that’s your answer. (1)

Element: a basic substance that can't be simplified (Hydrogen, Oxygen …)

Atom: the smallest amount of an element Molecule: formed when two or more atoms

are joined together Compound: a molecule that contains at least

two different elements

Ionic vs. Covalent

Ionic Bond: electrons are given by one atom to another. Ionic bonding happens between a metal and a non-metal (NaCl)

Covalent Bond: electrons are shared between two atoms. Covalent bonding happens between two non-metals

Types of Reactions Synthesis: When two or more simple compounds combine to form a

more complicated one. (2 elements get married)

Decomposition: The opposite of a synthesis reaction - a complex molecule breaks down to make simpler ones. (2 elements break up)

Single-Displacement: This is when one element trades places with another element in a compound (one element steals another elements girlfriend)

Double-Displacement: This is when the two different molecules switch one of their elements, forming two different compounds. (wife swap)

Combustion: When oxygen combines with another compound to form water and carbon dioxide (that’s the simplest way to think of it already…)
