Xtreme Science

 

Join us this term for The Science of Cold!

  • Xplore Chemistry - the Science of Cold with DashX’s Xtreme Science!
  • Xperiement with Dry-ice, Instant-ice, and even Hot-Ice!
  • Find out what Xtreme cold does to chemical reactions (and glow sticks)!
  • Make cold water boil and normal water freeze before your eyes in seconds!
  • Use chemistry and cold to create a tasty ice-cream treat!
  • Grow sodium acetate crystals!
  • Calculate what a “Red-Hot Knife vs Ice Block” will do, then try it!

Weekly Lesson Plans

1) No Class

Week #

Break Classes will start next week!
 

2) Cold Boil - States of Matter

Week #

 This week we will begin Xploring the Science of Cold!
To understand what cold is, we need to understand what heat is; and to understand heat we need to understand matter itself!

Demo

  • Water normally boils at 100 degrees Celsius, but can we force it to boil at room temperature?

Concepts

  • Laws of Thermodynamics
  • States of Matter (Solid, Liquid, Gas, Plasma)
  • Melting point
  • Boiling point
  • Sublimation & Deposition
  • Freezing & Melting
  • Vaporization (Boiling) & Condensation
  • Ionization & Deionization

What to Bring

  • Backpack by Deemak Daksina from the Noun Project Class Supplies ( Pencil, Eraser, Notebook, Ruler, Calculator)

 

Homework

  • Find a Homemade Ice cream Recipe you like


3) Salty Ice(cream)? - Melting Points

Week #

 Last week we learned about melting points; this week you will do an experiment to see what salt does to the melting point of ice.
You will then use your new-found knowledge to see if you can create ice-cream!

 

Concepts

  • Melting point
  • Freezing-point depression
  • Equilibrium
  • Heat transfer
  • Phase change
  • Foam
  • Dispersion
  • Solution
  • Emulsion
  • Micellar Phase

What to Bring

  • Device (tablet and/or laptop)
  • Backpack by Deemak Daksina from the Noun Project Class Supplies ( Pencil, Eraser, Notebook, Ruler, Calculator)
  • If you want to have a special ice cream flavor you will need to bring your own
    DashX's Basic Vanilla Recipe will be provided if you don't bring your own
  • Ingredients for your own Homemade Ice cream recipe (OPTIONAL)
    • We will be making the ice cream inside a bag using Salt & Ice
    • We won't be using a mixer or blender (look for recipes that use an ice cream maker)
    • Make as much of the recipe as you can ahead of time!
    • 75 Recipe Suggestions
    • DashX's Basic Vanilla Recipe will be provided if you don't bring your own

4) Feeling a Little Cold? - Temperature

Week #

 Humans do NOT make good thermometers and we are going to find out why! 
This week we will learn about what temperature, cold and heat really are, and how they move.
We will also have a look at the science behind the Salt & Ice we used last week to make ice cream.

 

Demos

  • Human Thermometer
  • Heat Pipe
  • Thermochromic pigment
  • Ice Melting Race

Concepts

  • Temperature
  • Thermal conductivity
  • Heat
  • Absolute zero
  • Joules & Watts

 

What to Bring

  • Backpack by Deemak Daksina from the Noun Project Class Supplies ( Pencil, Eraser, Notebook, Ruler, Calculator)

5) Hot Ice - Supersaturation

Week #

 Crystals are a very important part of chemistry; we are going to make some fast-growing crystals that look like ice, but are HOT!

Concepts

  • Supersaturation
  • Saturation point
  • Dissolving
  • Solutions
  • Crystallization
  • Exothermic reactions

What to Bring

  • GlassesEye protection
    (Safety Glasses will be provided, however some students may wish to bring their own that may be more comfortable)
  • Backpack by Deemak Daksina from the Noun Project Class Supplies ( Pencil, Eraser, Notebook, Ruler, Calculator)

 

This week's lab will be done as a tutorial.

Here are some videos if you want to try this experiement at home.

Here is a link if you want to buy some Sodium Acetate.

6) Hot vs Cold - Specific Heat

Week #

 We have learned that different objects have different amounts of heat, now its time to look closer and figure out exactly how much heat energy an object has.
We will do the math to figure out how big an "ice-cube" you would need to cool your pool down on a hot day.
We will prepare for next week's "Heat Battles" by calculating who will win, and by how many degrees!

 

Concepts

  • Specific heat
  • Latent heat of fusion
  • Latent heat of vaporization

Calculations

  • Red-Hot-Knife vs Ice-Block
  • Hot water vs Cold water
  • Ice Cube vs Water
  • Aluminum vs Water

 

What to Bring

  • Device (tablet and/or laptop)
  • Backpack by Deemak Daksina from the Noun Project Class Supplies ( Pencil, Eraser, Notebook, Ruler, !! Calculator!!)
  • Scientific Calculator - a must this lesson

7) Red-Hot-Knife vs Block-of-Ice - Latent Heat

Week #

hot vs coldLet the "Heat-Battles" begin!
You will find out if your predictions from last week are accurate, and see who really will "win" when we put a
Red-hot-knife up against a Block of ice!

 

Concepts

  • Specific heat

What to Bring

  • GlassesEye protection
  • Device (tablet and/or laptop) REQUIRED for this lab
    (Safety Glasses will be provided, however some students may wish to bring their own that may be more comfortable)

-) ONLINE ONLY - Instant Ice - Supercooling

Week #

 We've made fake instant-ice (when we used sodium acetate),
now it's time to find out if we can make real Instant-Ice (from real water)!
We are going to learn about supercooling, and maybe attempt to supercool some bottles of water!

We will also look at the results of last week's lab.
Why did ice always win?

 

Concepts

  • Supercooling
  • Deposition
  • Nucleation

Here is a playlist of five videos about making Instant Ice you can try at home!

-) ONLINE ONLY - Dry Ice - Sublimation

Week #

 https://www.flickr.com/photos/29233640@N07/Dry ice is amazing! It is solid carbon-dioxide,
has a temperature of -78°C,
and you are going to watch some amazing experiments with it!

 

Concepts

  • Sublimation
  • States of Matter
  • Vapor
