Day 21

Today we started the treatment on our plants. We watered each sprouted plant with 10mL of water, we watered the acid group with a solution of half lemon juice to half water. The basic group was watered with a solution of 20% soap and 80% water. The neutral was watered with plain tap water. We measured our plants to compare the heights now and at the end. The measurements before the experiment were as follows:
Acid- 2.0cm (shortest) & 5.0cm (tallest)
Basic- 3.0cm (shortest) & 6.0cm (tallest)
Neutral- 1.0cm (shortest) & 5.5cm (tallest)

The average height was 3.75cm.

In a week we will measure our plants again to see if anything has changed since the treatment began.
