Will Honey Flow At A Quicker Pace When Temperature Is Increased? Hypothesis: Honey will flow quicker when heated.
Aim: To discover whether honey will flow at a quicker pace when temperature is increased. Equipment:
500g Homebrand Woolworths Australian Honey
Chopping Board
Something to rest chopping board on (to create a ramp)
Newspaper
Tea Towel
Stopwatch
2 plates
3 teaspoons
Microwaveable Mug
Risk Analysis:
Hazard
Risk
How to Minimise Risk
Hot Honey
Burns
Handle any hot equipment by holding with a folded tea towel. Working with glass
Cuts
Handle glassware with care to ensure no smashing.

Method:
One teaspoon of honey was placed in the freezer on a plate and left to chill for 45 minutes. A ramp was constructed out of a chopping board placed on a jar of peanut butter to create a slope for testing flow of honey. Newspaper was placed underneath the ramp to reduce any mess made. One teaspoon of room temperature honey was placed at starting board on ramp. A stopwatch was used to measure the length of time taken for the honey to flow from the starting point till the first drop reached the newspaper at the bottom. Ramp was washed, wiped clean and placed on a fresh piece of newspaper. Honey was squirted into a microwaveable mug until the entire bottom of the mug was covered. Mug was placed in microwave for 5 seconds on medium high, heated honey was (insert degrees). Once heated, one teaspoon of honey was collected from mug and placed at Ramp starting point to record flow time. Ramp was washed, wiped clean and placed on a fresh piece of newspaper. Chilled honey was removed from freezer and quickly scraped with a teaspoon onto Ramp starting point to record flow time.

Significance of Results
Variables
My independent variable in this experiment is the temperature of the honey. My dependant variable in this experiment is the flow time of the honey. The additional variables controlled in my experiment were;

Amount of honey
Slope of ramp (240)
Same environmental conditions
Clean board throughout testing

Control
No control was required as three varying temperatures were to be compared. Reliability
Used the same brand/size teaspoon. Measured the angle of my slope to ensure it stayed the same throughout the experiment. The board was washed and dried after each trial to prevent interference. Experiment was performed three times to ensure
