Labelling
Label the different parts of the water cycle.
Transpiration
Ground water
Precipitation
Evaporation
3
Transpiration- plants release water vapor into the atmosphere
Temperature allows Stoma to release MORE or LESS water. Too much water lost is bad for the plant.
Cuticle keeps water in the leaf so it can only leave through Stoma
Water
Nutrient- a substance that helps an organism grow, develop, and survive.
Water, nitrogen, phosphorous
Nutrients
Used for Photosynthesis
Light

Reorder
From the soil- place the next place water flows through the plant and back into the air.
roots
stem
leaves

Technicians planted the same several types of lettuce in two identical aquaponic systems on the same day.
Both sets of lettuce received the same amount of water and grew for the same number of days.
Each setup received light from a different type of light fixture.
Group x= Fancy Light fixture
Group y= A Normal light fixture
Light Experiment!

Fancy light vs normal light
Fancy light tall plants
Normal light short plants
Fancy light average lettuce harvested 133g
Normal light average lettuce harvested 79g
