Thanks Harrison you have completed a good Science Fair. You have followed the Science process and produced an easy to follow board that clearly shows your findings. It is pleasing that you have included some research about onions to back up your findings. Presentation is not something that everyone enjoys, but with a little care and attention e.g. backing/boarders your display could have been presented to the quality of your findings & research.

 * Student Comment:**
 * I enjoyed science fair this year more than last year. I found it easier because last year I left it to the last minute and I had a hard topic.This year my experiments didn't take hours. **

Science Fair

Introduction:

I am interested in this because it is annoying when my eyes water when cutting onions.

Aim:

To find out a method to prevent eyes watering when cutting onions.

hypothesis:

I think the onion cut in the water will be the least likely to make your eyes water because the gasses in the them won’t be in the air.

I think the normal onion will be the most likely to make your eyes water because there is no protection from gasses and the gasses will be in the air

Equipment:

8 onions

my results show that the onion cut under water is the best way to cut a onion as my eyes did not water when i cut onions under water. the second best way was putting a onion in the fridge then cutting it

I found out that cutting a onion under water was best way to cut a onion and that cutting a onion normally was the worst. My hypothesis was correct.The reason why cutting the onion under water was the best way was because the gasses in the onion could not get in the air.

Introduction : I am interested in this because it is annoying when my eyes water when cutting onions.

Aim: To find out a method to prevent eyes watering when cutting onions.

Equipment: 8 Onions 4 refrigerated Onions 1 Knife 1 Stop Watch 4 People

Method:

1. Get onion 4. Once eyes start watering stop the stopwatch <span style="font: normal normal normal 13px/normal Helvetica; letter-spacing: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;">5. do the same for under water except make sure the onion is under water
 * 1) <span style="font: normal normal normal 13px/normal Helvetica; letter-spacing: 0px;">get stop watch
 * 2) <span style="font: normal normal normal 13px/normal Helvetica; letter-spacing: 0px;">start stop watch and start cutting

Update your Wiki if you have done this. Start your experiment as soon as possible. I will be interested in your results as I hate cutting onions they make my eyes water too!**
