Chia Seed Lab

By: Caitlin McCann and Maggie Miller

How does the type of dirt, fertilized or unfertilized, affect the growth of chia seeds?

Research: https://sproutpeople.org/growing-chia/ Chia seeds can take 5-14 days to grow and require about ¼ cup of water each day.


Hypothesis: If you put chia seeds in different kinds of soil, then they will grow at different rates because one is growing in fertilized soil and the other is growing in unfertilized soil.

Variables:

Independent Variable: The types of soil (fertilized or unfertilized)


Dependent Variable: Growth (cm.)


Extraneous Variables: Weather (cloudy or sunny, i.e., amount of sun received)


Control Variables: Same person planting seeds, seeds from same package

Our chia seeds grew well

Results:




Day # ....Fertilized Soil Growth (Cm.).....Unfertilized Soil Growth (Cm.)


1..................................0 cm........................................... 0 cm.

2 .................................nd................................................. nd

3................................. nd .................................................nd

4 .................................nd .................................................nd

5................................. 2 cm.......................................... 1 ½ cm.

6................................. 3 cm.......................................... 2 ½ cm.

7................................. 3 ½ cm...................................... 2 ½ cm.

8................................. nd................................................. nd

9................................. 4 ½ cm...................................... 3 ½ cm,

10............................... 6 cm.......................................... 4 ½ cm.

11............................... 8 cm........................................... 5 cm.

12............................... 9 cm.......................................... 7 ½ cm.

Conclusion:

Our hypothesis was was accepted because the fertilized soil seeds grew at a faster rate than the unfertlized seeds.

What would we do differently

Next time do more research on the effects of fertilizer on seeds
