Every topic is a case. Every answer needs a witness.
Fifty-six pieces of Marine Science broken down like evidence: a plain name first, the exam’s own term right behind it, and a worked number wherever a graph could turn into a wall of dots.
Three labs sit in the middle of the file: one for reading graphs and decoding what a question is really asking, one for building atoms into molecules, and one for drilling the formulas until NaCl and MgSO₄ stop looking alike.

Graph Lab
1 · Anatomy of a graph
Tap a numbered marker on the graph, or a line in the list. Every exam graph has these same parts — find them first, before reading a single value.
The parts
2 · Two points, one answer
Almost every calculation question is really “read two points, then do one sum.” Tap two points on the line and watch the whole working appear.

3 · Decode the question
A question is a set of instructions in disguise. Tap each highlighted word to see what job it does, then walk through the answer one step at a time.
Particle Lab
1 · Three states, one rule
Straight from your own page: the only thing that changes between solid, liquid and gas is how much the particles are allowed to move. Heat adds kinetic energy; particles vibrate faster.
The flat bits are the trick
While ice melts or water boils, the temperature stops rising even though heat is still going in. That energy is being spent separating the particles — latent heat. On a heating graph those plateaus are where the state is changing, not where “nothing is happening.”
2 · Inside an atom
Pick an element. Protons and neutrons sit in the nucleus; electrons fill the shells from the inside out — 2, then 8, then 8. The outer shell decides everything about bonding.
What the outer shell wants
3 · Build a molecule
Tap atoms into the beaker. When the counts match a real substance, the lab tells you what you made, which bond holds it together, and where it turns up in the sea. Metal + non-metal → ionic (give and take). Non-metal + non-metal → covalent (share).
