Hypothesis :
Putting less sugar on the stick when making rock candy will make larger candy
so..
If we put no sugar on one stick, a little suger on one stick, and a lot of suger on one stick, the stick with the least sugar should grow the biggest.
Materials
- 3 sticks
- Sugar
- Water
- Pan/Pot
- Jar
- wire or string to hand sticks
Redo materials
- 3 Pieces of String
- 2 sizes of Sugar
- Water
- Pan/Pot
- Jar
1. Procedure:
Make the rock candy Solution
- Boil 2 parts sugar to 1 part water
- stir constantly
- as soon as liquid is clear, remove from heat
- Let cool
- pour into jar.
- suspend rock candy sticks/string into jar
- 1- no
- 2 - little
- 3 - Most sugar
3. Put Sugar on Sticks
4. Hang sticks in Sugar water
Observations:
Day 3:
1. stick 3: bumpy looking like a crystal : Above water
2. stick 3: nothing below water
3. stick 1: nothing
Note: we are going to retry it again, because rock candy is not growing.
Re-Do of experiment. (TODO: Type in Tylers Notes)
Day 5:
The rock candy wasn't growing so we are going to redo the experiment again
Changes
1. We are going to redo it with string
2. Two sizes of sugar .
- One String no sugar,
- One string with small sugar
- One string with Chunky sugar
3. Same Hypothesis: Putting less sugar on the string
when making rock candy will make larger candy
when making rock candy will make larger candy
Day 8:
Observations:
1. The ones that have sugar on it are growing at the same time.
2. The one with no sugar is not growing
3. The blue one is a little bigger
Day 10:
The one that has no sugar was growing an iceburg on top of the water
Day 12:
Observations:
1. The white and blue is growing straight crystals
2. The blue is chunkier
3. The white one is clear
4. The one with no sugar has a little bit of sugar on the
string
string
Conclusions
1. Our Hypothesis was wrong
2. The Blue one was the biggest
3. The blue one had the most sugar to begin with
So, If you want to grow the biggest Rock Candy, you use
string and start with a lot sugar on the string.
