Labelling

Label the different parts of the water cycle.

Drag labels to their correct position on the image

Transpiration

Evaporation

Precipitation

Ground water

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.

1. How do animal / human nutritional needs differ from plant nutritional needs?

2. In what ways do we differ in getting nutrients?

• 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!

Word Cloud

Hypothesis: Write 1-2 words about which light you believe will grow the most lettuce.

(Word bank: Fancy light, normal light, more, less, same)

Conclusion: Which type of light gives better growth?
Claim-The (fancy/ normal) light gives better growth of the lettuce.

Evidence- The data shows...

Reasoning- Why does this matter? The lettuce needs light to grow because... The best light to give it is... because...
