Dharani's Plan
Okay... i have decided to go with my second idea! I want to find out what solvents preserve a fruit or vegetable better and why.
To do this, i am going to put a sample of a fruit or veg. in each solvent. I am planning to have a celery stick in water, a celery stick in vinegar, a celery stick in a sugar-water solvent, a celery stick in a oil and a celery stick at room temperature. After two weeks i shall see which fruits have been preseved the most. I will also do the same with a tomato as well and see whether the results vary.
My independent variable is the type of solvent there is in each sample.
My dependent variable is how much of the fruit or vegetable is preserved.
My controlled variables are how much solvent is kept in each sample, the time each fruit is kept in a solvent and how large or heavy each fruit is.
okay dharani is now officially excited about science! ( i know, this is a REALLY weird feeling)
well then...until my next blog... bye!
I'll miss you bloggy :(
Ideas
okay people... dharani has ideas! (some original and some from science experiment websites)
idea 1. have a vegetable in different temperatures (independent variable) e.g. freezer, fridge and room temperature and see whether the fruit becomes heavier(dependent variable).
idea 2. put a fruit in different solvents(independent variable) and see if this preserves the fruit(dependent variable).
idea 3. Put different fruit (independent) that you are not allowed to put in aeroplane jelly, in aeroplane jelly and see what happens and why(dependent variable).
okay then that's all for now!
