The gardener wanted to find the best water to use for growing his plants. if plants need a more neutral ph water for optimal growth, then a ph that is too high or too low will result in less plant growth. the gardener had 4 groups of water treated plants:
1. ph 4 acid water;
2. tap water of ph 6.8;
3. near neutral deionized water;
4. ph 8 basic water.
he would water everyday and every 3 days the gardener would measure and record the height of the plants in centimeters. after 5 weeks the gardener concluded that the tap and deionized water were almost double the height as the ph 4 and ph 8 water.
identify the:
1. independent variable
2. dependent variable
3. control
what is the conclusion from the experiment?
• undetermined
• reject hypothesis
• accept hypothesis
