Lolly Snake Experiment

By Matt G, Cam G and Brayden D8 Jade2012

Hypothesis and AimThe aim of this experiment was to find out which liquid dissolves lolly snakes the fastest and how long the different liquids take to dissolve the lolly snakes.

Our hypothesis is that the Vinegar, Boiling Water and lemon Juice would dissolve the lolly fastest, Plain water and orange Juice the slowest.

Risk assessment • Don’t get the

liquids in your eye• Be careful with the

Bunsen burner• Learning kills

Apparatus and Method• 5 lolly snakes• Five 50ml beakers• Stopwatch• 60ml of water• 20ml of pure lemon juice• 20ml of pure orange

juice • 20ml of vinegar• Bunsen burner• Gauze mat• Tripod• Matches• Heat proof mat

• Step 1-Collect apparatus• Step 2-Set up equipment• Step 3-Fill 2 beakers with

30ml water then fill the remaining beakers with the other liquids

• Step 4- Heat one of the water filled beakers to boiling point

• Step 5- Start a timer and put a snake in each beaker

• Step 6- Record your results in a table like shown on next slide, stating what you see is happening

Results

ConclusionWe have concluded that the effects of acids on lolly snakes causes the exterior of the lolly to silicify and go slimy as the gel and sugar of the lolly dissolves into mush.
