2.) Mark waterline

3.) Add duckweed

4.) Observe

If the type of water is changed (Saltwater, community park water, filtered water, and tap water) it will not affect the growth of the duckweed.

Alternate Hypothesis

If the type of water is changed then it will affect the growth of the duckweed.

Prompt: Does the type of water affect the growth of duckweed??

The type of water does affect the growth of duckweed as there are different amounts of nutrients in the water. High levels of nutrients mean more duckweed and fewer amounts of nutrients mean less duckweed. For example, ranging between 15 to 20 leaves of duckweed, community park water has the highest amount of duckweed. In contrast, tap water comes last because of its low nutrient levels and healthy water conditions, which is again proven by the chart above, as it has almost 5 to no duckweed leaves. This shows that the type of water does affect the growth of duckweed.

If the traps are placed near the water area then the biodiversity will not increase.

Alternate Hypothesis

If the traps are placed near the water area then the biodiversity will increase.

• Tie the strings on the trap

• Take off the paper protecting the glue on the paper

• Hang traps on the plants or trees

• Identify plants or trees using the Seek app and note down the species of the plants or trees.

• Take traps down and identify the organisms cached on the traps using the Seek app and calculate biodiversity

Prompt: How does proximity to water affect biodiversity??

Proximity to water affects biodiversity. In other words, the closer an area is to the water, the more biodiversity it has. This can be proven by Simpson's Biodiversity graph, as we can see a consistent increase in the numbers the closer the locations get to the water. For example, the hill area has a score of 0.72, then the marsh area has a score of 0.76, and the bridge area, which is the closest to the water, has a score of 0.84. This shows a consistent increase in biodiversity because the hill was the farthest location from the water, and it has the lowest Simpson's Diversity Index score (0.72), whereas the closest location, the bridge, has the largest score (0.84) compared to the other two.

If the spinach leaves are placed in sunlight the CO₂ levels will not be affected.

Alternate Hypothesis

If the spinach leaves are placed in sunlight the CO₂ levels will be affected.

• Put 15 spinach leaves in a container

• Connect CO₂ sensor to Chromebook

• Stick the sensor into the container

• Put the container/sensor under sunlight

• Record the CO₂ levels

Dark Lab

• Put the 15 spinach leaves in a container

• Cover the container with foil paper

• Stick the sensor (Make sure it's connected to the Chromebook) in the container

• Put it under sunlight (for constant temp)

• Record the CO₂ levels

Prompt: Does light affect CO₂ levels in a closed container of spinach leaves?

Light does affect CO₂ levels in a closed container of spinach leaves. Light does this by being a crucial player in the photosynthesis process. This happens when photosynthesis occurs and the light energy is used by the plant to convert CO2 and water into glucose and oxygen. We can see this is proven by the graphs above as when the container with spinach leaves is placed in the dark, the average amount of CO2 levels is 343.5 which shows us that photosynthesis did not occur as there was no light for the leaves to do so, whereas when the leaves were placed under sunlight the graph shows us that the average amount of CO2 levels is -309.5, which again proves that photosynthesis did happens in that container and the CO2 levels went down because of the presence of light over the leaves.

Germination does not affect the respiration rate of the mung beans.
