Water vs Saltwater vs Ice tea
Grade 6
Presentation
No video provided
Hypothesis
Hypothesis: we think that The Saltwater plant will die, and the iced tea one will Grow🌱. Why do we think this because Saltwater tastes gross and if plants taste like us it'll probably die because if I had a drink salt water all day every single day I would probably die!!!!!!
Research
Some plants do need some different nutrients
How do people nourish and grow ferns:
Ferns need indirect light
Temperate temperature (room temp)
Consistent water
Feed on schedule
10-10-10 fertilizer ratio (nitrogen, phosphorus, potassium)
How to water ferns
- Not being drenched
- It likes water ever 4 - 5 days

What nutrients are in Iced Tea, Saltwater and tap water (ions for water)
Iced Tea
Total fat 0g 0%
Saturated 0g 0%
Trans fat 0g
Polyunsaturated fat 0g
Monounsaturated fat 0g
Cholesterol 0mg 0%
Sodium 7.1mg 0%
Total carbohydrates 0.7g 0%
Salt water
Sodium chloride (salt)]
And small ion traces such as:
Calcium
magnesium (Mg)
sodium (Na)
potassium (K)
and water
Variables
what liquid do we water the plants
Procedure
Procedure:
- Gather materials
- Pot plants and label with tape and paper
- Figured out measurements of each liquid (100mL)
- Water plants with ‘Water’, make observations
- Make Ice Tea solution, mix ¼ cup of ice tea powder with water (100mL)
- NOTE - Make sure that you use a cup that won’t leak
- Water plants with ‘Ice Tea’, make observations
- Make Saltwater solution, mix ¼ cup of salt with water (100mL)
- NOTE - Make sure that you use a cup that won’t leak, heat water up to 70 degrees celsius and then mix in salt or else it will not dissolve fully.
- Water plants with ‘Saltwater’, make observations
- Take a picture the next day so that results have set in.

Water (Control) |
Growing like a normal fern plant |
No changes |

No changes |

Ice Tea |
It looked like a normal healthy fern plant |
The leaves are getting longer and healthier than the water plants |
It was starting to wilt and get dry and crispy.The soil had a layer of white mold on it |
There's this white layer forming on top of the dirt and its sponge,I think its mold and it smells.The tips of the leaves were brown and the whole leaf was smushy |
|
Saltwater |
It looked normal and healthy |
It started to wilt and turn brown |
It was getting crispy and the leaves were falling off |
It died!!!,the leaves were falling and it was almost fully brown |
Analysis
Analysis:
There was no change in the water (control), the iced tea turned mushy, but the saltwater turned crispy.
Why did the saltwater turn crispy?
Why did the iced tea turn mushy?
Conclusion
Conclusion:
Fern plants do not like a whole lot of salt water, and they need the hole in the Bottom of the pot Otherwise the water will Clump on top and make it that it has a hard time doing photosynthesis with the sugar from the ice tea and the salt water and not being able to drain it out makes it really hard. Ice tea isn’t good for long term plants but for one-three days the plant thrives pretty good.
Ice tea
Ice tea has too much sugar for the fern. The sugar in the ice tea made a layer of mold on the top of the of the pot, so that the plant.The sugar makes the water the water that is in the iced tea go away because on the bottom all the sugar sinks so sugar is heavier than water and the sugar all sinks on top of the dirt and then that means that there's a layer of sugar and then the water.
Salt water
So some things with salt water are kind of the same with iced tea but they don't have sugar the opposite is I'm salt water because salt is heavier than water so the salt floats down to the bottom and makes a nice layer of salt on top of the dirt and then as the water does it just stays on top of it so technically you're getting salt the plant is taking salt in more than the water is that's why it died
Application
If you get a pregrown plant and its showing no progress than you can water it with ice tea for two to three days(to give it a boost) then switch imediatly to water.
NEVER WATER WITH SALT WATER!
Sources Of Error
Source of Error:
- We would add holes to the bottom of the pot
- Water in to big portions
- Water to close together
- Better tracked days
- Water every 4 - 5 days
- If watered 4 - 5 days have a longer time frame
- To much salt
