Slide1

Rock candy !

What kind of rock grows? Slide2

This delicious candy is actually crystalized sugar and you can grow it from your own sugar-water solution. As a kid I thought rock candy was amazing, and I still think it looks pretty neat! You will learn that making your own rock candy is a fun and tasty way to grow crystals and see the structure of crystals on a big

scale as they form into rocks.

To get you to better understand the three different types of rocks,

Igneous

,

Sedimentary

and

Metamorphic

, we will explain each type of rock by providing you with your own flavor.

Sounds

fun right? Now lets dig in! Slide3

Task

After studying rocks in our third grade science class, its your turn to show me how much you know

Each group will be handed a note card with facts about a certain type of rock

It’s now your job to determine what rock you have by using the different food coloring

Now it’s time to make your rock!Slide4

Step 1

Get into your assigned groups

Read the note card passed out to your team and determine if you guys are Igneous, Metamorphic, or a Sedimentary rock.Slide5

Step 2

Gather the ingredient's. You will need:

2 cups of H2O

3 cups of sugar

-1/4 cup corn syrup

-food coloring for your specific rock

-igneous:

RED

-sedimentary:

BLUE

-metamorphic:

GREEN

-cotton string/skewer

-paper clip

-jarSlide6

Step 3

Tie a piece of string around the middle of the pencil. It should be long enough that it is 1” above the bottom of the jar when placed on top the jar.

If you have a skewer, use a clothes pin and attach it to the center. Slide7

Step 4

Wet the string. Roll it in sugar. Slide8

Step 5

Remove the boiling water and stir in the sugar and corn syrup. Add 1tbsp at a time until it has dissolved.

Add in your designated food coloring

Must be assisted by your teacher Slide9

Step 6

Pour the sugar water into your glass jar.

Be careful it will be very hot.Slide10

Step 7

Tie a string (or skewer) to the center of a pencil.

Put the string (or skewer) in the water and have the pencil lay across the top of the jar.

Be sure to not have the string (or skewer) touch any part of

the jar.Slide11

Step 8

Place the jar some where that it will not be bothered

Be sure to not put it in a refrigerator Slide12

Step 9

Leave your string or skewer in the jar until you think the crystals are big enough.

These crystals will start forming in a day or so.Slide13

Step 10

Now you can remove the string or skewer from the glass jar and let it dry.Slide14

Step 11

After it dries…it’s time to eat your rock candy!Slide15
