The document describes an experiment to determine the best way to store strawberries to keep them fresh. It outlines predictions that strawberries stored in foil or a paper towel-lined bowl will fare best. The experiment involves storing 4 groups of 3 strawberries in different conditions - an airtight container, bowl with paper towel, original packaging, or foil - and observing each day which strawberries become mushy, excrete moisture, or grow mold first.
Fair test method etc
- 1. What’s the best way to keep strawberries fresh? A fair test conducted by Amy Dellosta 2012
- 2. Question for investigation • What is the best way to store supermarket bought strawberries to keep them fresh (not mushy, mouldy or excreting moisture) longer?
- 3. Predictions… • I predict that the strawberries kept in the foil in the fridge be the first ones to go mushy and mouldy. • I predict that the strawberries in the fridge in the bowl with paper towel will stay fresh longest.
- 4. Things to be kept the same • Purchase date of strawberries
- 5. • Number of strawberries in each group 3 strawberries relatively same shape and size in each group
- 6. • Storage position -All strawberries kept in same fridge, on same shelf
- 7. What is to be measured? • The freshness of the strawberries is to be measured. I will be documenting how many days it takes for each group of strawberries to have one strawberry that becomes mushy, leaves moisture on a surface and/or becomes moudly.
- 8. What is to change? • The way the strawberries are stored. There will be 4 different storage solutions • 1. Airtight circular container with lid.
- 9. • 2. Ceramic bowl, lined with paper towel, no covering
- 10. • 3. Supermarket packaging. Square plastic container, with air holes top and bottom.
- 11. • 4. Wrapped tightly in foil
- 12. Equipment • 4 groups of 3 Strawberries bought on the same day and roughly the same sizes • Fridge • Airtight plastic container • Foil • Bowl • Paper towel • Supermarket container
- 13. Procedure 1. Sort strawberries into 4 groups of 3 strawberries, roughly same sizes 2. Place each group into designated container 3. Place all containers/storage into fridge on same shelf 4. Check and film strawberries daily for change
