||We had three different cups of water with celery. In the first cup we had 100% water solution, the second cup had 10% salt and the third cup had 20% salt. The first cup of celery curved the most and the second and third cups were pretty straight.
||We want to test the question, will 100% water solution affect the bend of the celery more than 15% salt water solution?
||We think with our experiment, the complete water solution will cause the celery sticks to have more of a bend. We also think the saltwater solution will cause the sticks to become more flimsy.
||We will test this by taking sticks of celery and make them all the same size at 4 inches long and 1cm in width. One cup will be filled with 100% water and have two celery sticks completely submerged. The secomd cup will have a 15% salt water solution with two celery sticks. Both cups will have 250ml of water. Once these are assembled we will label the cups and let the celery sit for three days. On the fourth day we will find how the celery has changed by measuring the inside curve of the bend in cm. By measuring this we will see which solution caused more of a bend in the celery.
