Question: How to do the results for this science experiment?

I have to write up an experiment for the effects of phototropism on plants and I was wondering what I should put in the results section other than my observations? My teacher said to include tables and graphs but I’m not sure what to put in a table or a graph that would relate to phototropism. For my experiment I used 4 cress plants and they successfully grew towards the light.

Answer: Here are a couple of ideas:
1. Angle of the leaves vs. time.
2. Angle of the stem vs time.
3. Distance from vertical to the top vs. time.

Make sure that you put the light on the opposite side and see what happens.

Question: what is water? science help?

Science experiment: you will be given two substances, water and something very similar but not exactly the same as water. aside from boiling, density, freezing, suds, touch,ph, evaporation, tests etc. come up with your own EXTREMELY CREATIVE test as to which one is water. ingesting is not an option, you will be graded on creativity.

Answer: H20

Question: I need to know everything about a hypothesis?

I need to know everything about a hypothesis and how to conduct one for the Science Fair coming up. I pretty much know that it’s an educated guess, but I’m going to need more than that. How do I find variables, I don’t quite get variables and what they are…again, I know the definition but I’m a bit fuzzy. The fields are: Biology; Chemistry; General Science & Engineering; Physics (which I’ am a little interested in); and lastly, Social and Behavioral Science

Answer: uhmm, first you need a quiestion. (i.e how do weather conditions affect polution) since your interested in computers you could do something like how does the brand of the motherboard affect the overal performance of the computer. you could also do like how does the tempurature of the room affect the overall performance of the computer.

as for the hypothesis. to write one in my class (9th grade honors science) we have to use this formula.

When…(the manipulated varible / deliberatly changed) is (increased or deacreased) then the (responding variable/measured outcome) (increases/ decreases/stays the same) This happens because (REASON WHY YOU THINK THAT WILL HAPPEN) and can be expained by … (EXPLAIN THROUGH SCIENCE/ USE DETAILS/ ANY BACKGROUND INFORMATION)
