IDEAS AND DRAFTS- 2nd Draft :)

This is my second draft! :) 


Topic of investigation: To find out which type of fruit or vegetable juice contains the most amount of electrolytes
Research question: Which type of fruit/vegetable juice contains the most amount of electrolytes?
Hypothesis: Lemon juice contains the most electrolytes
Purpose: Find out the juice with the most electrolytes so that athletes will be able to drink the fruit/vegetable juice with most electrolytes and benefit from consuming the natural components of fruits/vegetable juice instead of consuming chemicals and artificial components present in sports drinks. Fruit/vegetable juice can be a good alternative for them (to substitute sports drinks as excessive consumption of sports drinks may be bad for health in the long term)

Methodology for Second Draft (This is a brief procedure plan-out to aid me in conducting the experiment and is not exactly the same as the one in my report):

Materials:
- Blender to blend ingredients with water
- 1 guava, 1 mango, 1 orange, 1 lemon, 1 apple and 1 carrot-> these are the ingredients
- Knife to peel and slice the ingredients
- Masking tape and pen for labeling
- 100ml measuring cylinder
- Blender to blend the ingredients
- Plastic wrap and rubber bands to seal the mouth of beakers to prevent evaporation
- Datalogger 2.5V voltmeter and copper plates- measure voltage in juices.
- 6 250ml beakers
- Timer to time blending time: 2 minutes

Procedure:
1. Turn on the blender
2. Label each beaker a different juice. For example: "Guava juice, "Apple juice", etc. (Using the pen and the masking tape.
3. Cube the guava with a knife and chopping board and place them in the blender.
4. Measure 100ml of water in 100ml measuring cylinder and pour into blender. Repeat this to ensure 200ml of water will be in the blender.
5. Switch on the blender and blend for 2 minutes. Use a timer to time 2 minutes.
6. After 2 minutes, switch off the blender and pour guava juice into beaker labelled guava juice.
7. Rinse the blender thoroughly
8. Repeat steps 3-7 with the other ingredients but remember to remove the skins for all of them.
9. After pouring the juices into the beakers, seal the mouths with plastic wrap and rubber bands to prevent evaporation.
10. Set up the data logger and voltmeter. Connect the voltmeter to the datalogger.
11. Connect the copper plates to the alligator clips of the voltmeter.
12. Mark areas on the copper plates to indicate the areas of copper plates exposed to the juices when measuring.
13. Remove rubber band and plastic wrap from "Guava Juice" beaker and expose marked areas of copper plates to the guava juice to measure voltage.
14. After data is recorded, remove copper plates and wipe them carefully with clean tissue.
15. Repeat steps 13-14 for each beaker.
16. Record data in table form.
