Lab Report

Before we started the experiment, we decided on a hypothesis. That was: Seeds germinated and grown in soda and "salt water" will not grow as well as those grown in plain water.

Control: The amount of soil and liquid  in the pots

As well as time

Variable:

Independent variable:  the liquid

Dependant variable: the growth of the plant

Justification of hypothesis:  

Why did you choose this as your hypothesis?

We chose this because water is the original factor in growing a plant, and it’s the most
reliable ingredient to test. So, we thought that because salt water was similar to water, it would
grow almost as fast.

Procedure:Pour the soil into three pots. Plant 20 cabbage seeds in each of the potsLabel each pot A, B, and C .Water pot A with water. Water pot B with the solution made up of salt and water pot C with Dr. Pepper. Measure growth over time.

Materials:

• Three pots labeled A, B and C
• Soil
• Cabbage seeds
• Morton salt
• Water
• 2 liters of Dr. Pepper
• 
  

Data and Results:

We watered each of the three pots wit 75 mL every other day. That’s everyday we came into this class.
We did this for about two weeks. Our controlled experiment grew the most.

Conclusions:

Our final analysis is that our control group grew the most. In fact, our other variables that got tested,
did not grow at all. We had a hunch that the salt wouldn’t grow..but we got a little disappointed
when the plant watered with Dr. Pepper hadn’t grown. Our plant watered with water, grew thirteen
sprouts all around the same height.

What do you know about seed germination?

It is a skill that involves growing seeds into a sprout.

What do you want to know about seed germination?

I want to know more about different types of seed germination and techniques.

What did you learn about seed germination?

I learned that it takes time and calculation for the plant to grow.
I also learned that one tiny thing can act as a variable and affect the growth of the seed.
