1. Does worm juice effect how
plants grow , taste and smell?

2. HYPOTHESIS
We think that the worm juice will make
plants grow better and taste better. We think
this because we are worm farm monitors
and we put the food scraps into the worm
farm for the worms to eat.
We know that plants need water and food in
the soil to make them grow better.

3. Materials
• Worm juice
• cold water
• 6 pots
• soil- from the veggie garden
• Measuring cup

4. Test Method
• Get 3 cauliflower pants and 3 mint plants
• Get 2 liters of Worm Juice from a worm farm.
• Get 6 clean plastic planting pots.
• Put soil in the pots 3/4 full.
• Put cauliflower and mint plants in the pots.
• Mix 1/2 cup of water with 1/2 cup of worm juice.
• Add this to each pot.Water twice a week Tuesdays
and Saturdays
• In one pot of cauliflower and a pot of mint water with
plain cold water-no juice.
• Leave3 in the garage and 3 inside. * Record the growth

5. RESULTS of1st test
• After 3 weeks all 6 plants died. They went
moldy and soggy!
We concluded that they were getting too much
worm juice and water. The three we put in the
garage died quicker than the ones in the house.
So we started all over again.

6. TEST 2
We decided to make the TEST fairer by
putting them ALL in the House on the
window sill of our family room.
This room has lots of light and it is warmer
than the garage
We added more soil into the pots too

8. RESULTS
After week 1 we noticed that the worm wee ones were
growing better than the water ones. They had grown from
6.1 to 7.2.
After week 2 we noticed that the worm wee ones were
growing and over taking the ones with water in them from
7.2 to 7.6
After week 3 the worm wee ones were still growing faster
then the water ones from 7.6 to 10.6
After week 4 we noticed that the ones with wee were still
over taking the ones with water from 10.6 to 12.5

9. Taste and Smell test
Compare your worm juice mint leaf with
control mint leaf. WW NO WW
SAME
PLANT PLANT
rub leaf onto paper - SMELL PAPER!
Does the worm juice one taste and
smell stronger? 2 2 6
More people thought that they were the
same but some people still thought there
was a difference.

10. More people thought that they were the same but some people
still thought there was a difference.

11. Taste Result
Make two mint drinks one with ww plant leaf in and
another with water plant leaf in.
The minted water drink made from the ww plant
was about the same as the water only plant ones.
3 tasted it, Mum, sister and me
Me and my sister thought the ww was stronger,
mum thought they were about the same
So I can’t really say it is really stronger I needed
to test it on more people

12. Conclusion
• Cauliflower and mint Plants grow bigger
and quicker if you use worm juice mixed
with water Half water and half worm juice.
• We needed to ask more people to taste to
get a more accurate result
• There was not much difference between
the ww leaf and the no ww leaf in the smell
of it
