# Chia Seed Lab

## Does the amount of chia seeds in a pot affect how tall they grow?

Research: We found a website saying to plant chia seeds 12 inches apart, so we decided to see if putting them closer together would affect their growth.

## Hypothesis

If there are more seeds, then they will struggle to grow because it is too crowded.

## Variables

Independent variable: The number of chia seeds

Dependent variable: Height (cm)

Control: One chia seed

Standardized/controlled variables: size of chia seed, spacing between seeds when planted, and amount of soil and water they are given

Extraneous variables: uneven amount of sunlight

## Procedure

1. Fill 3 dixie cups with same amount of soil.

2. Put 1 seed in the middle of the soil about an ½ inch deep in the first dixie cup and label this cup 1 (control).

3. Take second cup and place 4 seeds within 1 square inch of soil and press them in 1/2 inch deep. Label this cup with a 4.

4. Put the remaining 8 chia seeds within 1 square inch evenly spaced out. Place the seeds 1/2 inch deep. Label this cup with an 8.

5. Water the seeds every day for 9 days (not including weekends)

6. Measure and water each weekday. Do not water on weekends.

7. After 9 weekdays compare the heights of the sprouts with how close they were to each other.

## Results

The cup with 4 chia seeds had the most growth. The cup with 8 chia seeds took slightly longer to start growing and the cup with 1 chia seed didn't grow at all.

## Conclusion

Some, but not too much, competition helps the chia seeds grow; therefore, our hypothesis was wrong.

## If We Could Do the Lab Again

We would do more research before beginning. We also have more cups with different amount of chia seeds.
