Hypothesis: Our hypothesis was that it would take around 4 to 5 turns in the vice before the lollie-pop would crack..
How many turns in a vice do you think a lollipop could handle? Aim: To test how many turns in a vice a lollipop could handle.
Apparatus: You will need: 3 different brands of lollipop 1 similar sized lolly(as your control) A vice Scissors Chupa chup (control) Different types of lollipop
Method: Set up your vice by attaching it to a bench or table. Cut the stick off your lollipop and unwrap it. Place your control (something of a similar size) into the vice and close it enough so it is stable but doesn’t have pressure put on it. Now gently start to turn the handle and make sure to count how many full turns it can take. It will eventually crack and make a mess. Record your data in a table and repeat the steps with your other chosen lollies. Look at the change in your records and test your hypothesis. Write a conclusion on what happens. Time allowance: 45 minutes max.
Risk Assessment: There aren’t many things that can go wrong in this experiment but make sure you were glasses so you don’t get lollipop in your eyes. Also be careful with the vice, they are heavy and will hurt your feet if it falls on them. Also you may want to wear your lab coat because it gets sticky and it is messy. Sticky business! BE CAREFUL!
Our results! Object:Estimate:No. of turns: control4 turns1 ¾ #121 ½ #21 ½ #311 ½ This is a table of our results, as you can tell our estimates weren’t too good, but we got the data and put it in a table. Our hypothesis was UNPROVEN!

Conclusion: This experiment was very fun and sticky! Our hypothesis was 100 % wrong but we enjoyed finding this out.. None of the lollipops took more than 2 turns in the vice. Improvement: We could have used a different vice that was attached to the bench as the one we used we had to hold down with our hands. We could have changed one of the lollipops to a gobstopper or used another brand of lollipop.
