PURPOSE: (Use 3rd person ONLY; use academic language- no "yuck")
Do you want you're (you mean "your"; this is 2nd person) strawberries to stop spoiling? We might have the solution! The project we're (this is 1st person) doing might have the solution by using thermotherapy on the strawberries to keep them from spoiling. The reason why we chose this project because it looked interesting and we wanted our hypothesis to be proven right.I mean who likes spoiled strawberries,YUCK!! The purpose were doing this project is to possibly solve your strawberry rotting worries even though it might not work that good who said we couldn't give it a try.
HISTORY:(Who first studied thermotherapy? Where? How does it work?)
(This paragraph works better in the PURPOSE section-->)Strawberries are naturally grown fruit,that are sweet and sour but the problem is that the strawberries rott way to fast and you want to enjoy them.Maya and I may have the solution to allow them to last longer.
PROCESS: Thermotherapy is usually the use of heat to treat a disease or disorder but in this case the thermotherapy is used on strawberries.The strawberries you could say have a disorder and thats to mold way to fast.The reason they mold so fast is the excess moisture they contain or receive.The reason there is mold because in every patch of strawberries a fungus called Botrytis cinerea grows.
APPLICATION:(USE 3RD person; What other methods are people using to preserve food? Can thermotherapy be applied to other foods?)
Thermotherapy can be used on other foods/fruits for example raspberries and blueberries.
REFLECTION: (see SF notebook for specific directions)
Maybe next time Maya and I can be more organized and not procrastinate because that was something that caught us off guard when something was due and we didn't have the assignment ready or done.This (specify) is something that can work in the real world when you want to save money but it goes down the trash in a couple of days when you do not eat the strawberries right away.You want to save your money as much as possible and every single penny counts when it comes to food.

PROCEDURE (Number each step, begin with commanding verb (see #1), include what data to record and how to conduct 5 trials
Fill the large pot with water and place it on a stovetop burner on medium heat. The pot should have enough water in order to cover a basket of strawberries, but not so much that the water spills over the side of the pot when you immerse the strawberries.
Take a pint of strawberries and separate them into two groups of about equal numbers of strawberries. Put each group into a new plastic basket. Assign a number to each basket and remember which is which. Record the basket number, the number of berries in each basket, and the date in your lab notebook in a data table like the one shown below. You will expose one of these baskets to thermotherapy and leave the other basket alone for comparison
3.Before placing a basket inside the pot, bring the water to 125°F. Use the thermometer to monitor the water temperature. Record the water temperature in your lab notebook. Spread out a clean kitchen towel.
4.Once the water comes to 125°F, turn off the burner and immerse one basket of strawberries into the hot water. Immerse this basket for 45 seconds (sec.). Use the timer to keep track and use the slotted spoon to keep the strawberries submerged.
5.After 45 sec. have elapsed, quickly remove the strawberries and the basket from the water and spread them out on the clean kitchen towel to dry and cool off. Use caution when working with the hot water. Use both the tongs and the slotted spoon to remove the strawberries from the water, and the paper towels to gently blot the strawberries off. Do not expose the second basket to thermotherapy.
6.When the strawberries are completely cool and dry, put them back into their basket. Note the condition of the strawberries. Do they still look red, or did the hot water affect the color and condition of the berries? Record your observations and the time that you immersed the strawberries in the hot water in your lab notebook.
7.Now wrap each of the baskets, both the treated strawberries (those that were heated) and the untreated strawberries (those that were unheated), in two layers of plastic wrap. This will create a nice humid environment for the berries.
8.Write the basket number, the conditions of the treatment (treated or untreated), the time of immersion, the date, and the trial number on sticky notes and label the baskets with the notes. Use masking tape to secure the sticky note the plastic wrap. Make sure to record this data in your lab notebook, too. The untreated baskets are control baskets. The purpose of a control is to act as a constant and to highlight any effects the variables in an experiment (like heat or no heat) may have on the experimental group. To learn more about variables and controls, read the Science Buddies page tfor a more in-depth discussion.
9.Now place the wrapped baskets in a location that will not be disturbed on top of a few pages of newspaper. The newspaper will absorb any excess liquid from the strawberries. Keep the baskets at room temperature and not in the refrigerator.
10.Repeat steps 1–9, except this time, immerse the strawberries for 3 minutes in 125°F hot water.
11.Repeat steps 1–9, except this time, increase the temperature of the water to 140°F and immerse the strawberries for 45 sec.
12.Repeat steps 1–11 two more times. It is important to perform at least three trials of your experiment so that you can be sure that your data is reliable and repeatable. The temperature and time conditions are shown in the table below:
HYPOTHESIS:
If thermotherapy is used on strawberries then it will prevent from lasting longer,from rotting faster.
