Kinetic Sand - Putting It All Together

Subscript, is a number that comes after an element. It tells you how many atoms of that element there are.
Ex. N₂ = 2 atoms of Nitrogen
F₂ = 2 atoms of Flourine
C₆ = 6 atoms of Carbon

Coefficients, tell you how many molecules (groups) there are of an elemental molecule or compound molecule. You distribute the coefficient to each of the elements and their subscripts (if available).

Ex:
3H₂O --> means there are 3 molecules/groups of H₂O
3xH₂= 6 Hydrogen (H)
3xO= 3 Oxygen (O)

Parenthesis works just like PEMDAS, parenthesis always comes first, so you must work the parenthesis part first, and then you can work the remainder of the problem.

Ex:
2H₂(O₂)₂ = Parenthesis first, so Oxygen (O) has 4 atoms.
Then work the coefficient and multiply everything by 2, so Hydrogen (H) = 4 and then multiply O₄ x 2 = total of 8 Oxygen (O) atoms.

Sand: SiO_{2
Corn starch:} C₆H₁₀O<sub>5

Vegetable oil:</sub>CnH₂

Made from 3 things: Play sand, corn starch, and oil.

Directions:

1. Mix two cups of corn flour with three cups of sand together in a bowl.

2. Pour half a cup of vegetable oil into the sand and flour mixture. You can also add some drops of food colouring at this point if you want to make coloured sand. Mix together with a spoon and then with your hands to squish it all firmly together.

3. Your sand is now ready to play with!
