For my science fair project, I want to discover what types of liquids promote growth of
plants, and also which liquids are pollutants and stunt the growth of plants.
The pH scale is a scale from 1~14 that measures the concentration
Which brand of popcorn will pop the fastest?
The brand with the most butter (PC), will pop the fastest, because oil helps cook food.

Landfills, the large pits in the ground used for storing waste, are being overflowed everywhere.
This is a huge problem as we are running out of places to put our waste. However, there are many
ways the situation can be improved.

For our science fair, Jacqueline and I will do a study on how different liquids will affect
the growth of bean plants. Our plan is as follows :
- 12 paper or Styrofoam cups
- 12 small plates (big enough to hold one cup ea
Out of all the plants that grew, the control, water, grew the fastest. Lemon juice grew

water, the plants watered with lemon juice grew the tallest,
We chose to do this experiment because as we are steadily decreasing the amount of fresh
water on earth, we need to know some alternatives that we can use for in its stead. This is
important to know, for we should not unnecessarily waste our

We watered our plants with acids and bases for our project. In order to do this, we did
some research about the pH scale. The pH scale is a scale from 1~14 that measures the
concentration of hydrogen ions, or the acidity or baseness of
For our science fair experiment, How Does Your Garden Grow? we did a study on the
effects of acids and bases on bean plants. We used a quick growing bean, the Phaseolus vulgaris
Speedy or the Dwarf/Bush Bean, to enable us to obtain results quickl
Our experiment was to water different bean plants with acids and bases to see how they
effected the growth of plants. We used a fast growing bean plant, the Speedy Dwarf Bean, or
the Phaseolus vulgaris Speedy, because our time for this expe
