Situation: While you were flying on the plane on your way to your beautiful resort vacation, the plane announces it will crash soon.
Everyone is told to take a parachute and jump out, and so you jump. You end up all alone on an island. You make a huge fire and you wait for help all day.
You become extremely thirsty. All there is to drink is the ocean seawater. Also, there is a huge iceberg floating near your reach. Should youa) Drink the seawaterb) Drink the iceberg’s waterc) Doesn’t matter, both are the samed) Don’t drink anything? (you’ll die of thirst)
Hint:
Seawater has a pH of ~7.5. It has a salinity of 3.5%.
Iceberg has a pH of ~7.5. It has a salinity of 0.5%
Concentration date
Concentration date
Concentration:When we measure the amount of a substance dissolved in the solution.
A solution is made up of a solvent and a solute.Solvent: the main chemical, can dissolve other substances.Solute: the small chemical parts in the solution.
Concentration
Concentration date
We can measure concentration!!
Concentration = _ solute__ solution

You become extremely thirsty. All there is to drink is the ocean seawater. Also, there is a huge iceberg floating near your reach. Should youa) Drink the seawater too concentrated in salt!!
b) Drink the iceberg’s waterc) Doesn’t matter, both are the samed) Don’t drink anything? (you’ll die of thirst)

Hint 2:
Humans shouldn’t drink a solution with too much salt.
This can cause excess peeing and dehydration, high blood pressure, sometimes severe enough to cause damage to kidneys and heart and kill you if you don’t get help!
TODAY, let’s find out…WHAT happens in our body to our cells when we eat too much salt??
Diffusion and osmosis date
Diffusion date
Diffusion: when a solution spreads out everywhere.This happens by itself because particles can naturally move around (vibration, rotation, translation of atoms)
