Does the amount of water affect the number of seeds germinated in 72 hours?

# data[].attributes.body
The amount of water will not affect the seeds germinated in 72 hours.

The amount of water will affect the number of seeds germinated in 72 hours.

# data[].attributes.body
1- Place the filter paper in 4 Petri dishes

2-Mesure and add 5, 10, 15, and 20 mls of water

3-Place 10 mung beans in each dish

4-Put on window sill for 72 hours

5-Record results

# data[].attributes.body
The amount of water does have an effect on the germination of beans. One piece of evidence that supports this claim is that the class average for 10ml germinated 8 seeds. Another piece of evidence is that the class average for the 5ml was 1.3 seeds. The last peice of evidence was that there was no overlap betweeen the 5mo and 10ml error bars, thier diffrences are statisticlly significant. This evidence supports the claim because the water is absorbed by the seed and it expands the seed. The water also provides oxygen to the seed and activates the enzymes for respiration, which provides energy for growth, and it is a catalyst to speed up the reaction.

Does the moisture affect the number of isopods in the choice chamber?

# data[].attributes.body
The moisture does not affect the number of isopods in the choice chamber.

Th moisture does affect the number of isopods in the chamber

# data[].attributes.body
1- Place paper on either side of the chamber

2- Leave one side dry and add 2 ml of water on the other side

3-Place 5 pillbugs on each side

4-Record data for 0-10 minutes

5-Pile all the data together to find the average.

# data[].attributes.body
The moisture does not affect the number of isopods in the choice chamber. One piece of evidence that supports this claim is in the experiment, the isopods were attracted to both the wet and dry sides, but all in all, the class averages were very similar for both sides. The average for wet was 4.95, and for dry, it was 5.05. The difference is only 1.0, so there is no statistical distance.

# data[].attributes.body
The temperature of the water does not affect the number of isopods in the choice chamber. In the experiment, the isopods had an average of 4.8 in the hot and 5.2 in the cold. The error bars show much overlap. There is no statistical difference in the hot and cold side.

Does the type of water affect the amount of duckweed grown?

# data[].attributes.body
The type of water water WILL NOT affect the amount of duckweed grown.

The type of water WILL affect the amount of duckweed grown.

# data[].attributes.body
1- Take 4 cups and put lake water in one, filter water in one, salt water in one, and tap water in one.

2- Place 10 live duckweed in each cup

3- Observe the changes in the duckweed over 9 days and take notes

4- Collect all the data

5- Take the data and put it in tables and graphs to find the conclusion.

# data[].attributes.body
The different types of water affect the amount of duckweed grown because of the nutrients in the water. One piece of evidence that supports this claim is the amount of duckweed grown in the pond water versus all the other types of water. At the end of the experiment, the duckweed in the pond water had grown from 10-22, whereas the other did not produce that significantly. This evidence supports my claim because the pond water had the most nutrients out of all the different types of water, and the duckweed did the best in the pond water. Duckweed thrive and multiply on the nutrients in the water; with them, they grow more. The nitrates and phosphates contain the protein that the duckweed needs to grow leaves. The pond water duckweed had a statistical difference in growth compared to the other types of water.

How does the proximity to water affect biodiversity?

The proximity to water will NOT affect the biodiversity.

The proximity to water WILL affect biodiversity.

1- Place glue traps in 3 different places: the hill, the marsh, and the bridge.

2- Collect all the traps

3- Count and identify the different amounts of species that were caught on each trap

4- Record all the data

5-Count the richness, abundance, and SDI.

# data[].attributes.body
The proximity to water affects biodiversity because the two locations closest to water sources have the highest biodiversity. One piece of evidence that supports this claim is the biodiverse index of the marsh and the bridge, which were closest to water. The marsh SDI is 0.88 and the bridge is 0.76. Another piece of evidence is the SDI of the hill, which was not located as close to the water. The SDI was 0.45 for the hill. These pieces of evidence support my claim because of the contrast between the SDIs of the locations close to water versus the hill. The biodevery was shown to be closer to water, and the locations closest to water had a higher richness than the hill, which shows the statistical difference in the biodiversity in both places.

Does light affect the Carbon levels in a container with spinach leaves?

# data[].attributes.body
The light does affect the Carbon levels.

The light does not affect the Carbon levels.

# data[].attributes.body
1- Put 20 spinach in 2 containers and leave the other 2 empty

2-Cover two containers with tin foil (with and without spinach)

3- Test the initial Carbon levels of each container

4-Leave the containers for 5 minutes then record the final Carbon levels

5-Find the difference to get the Carbon change.

# data[].attributes.body
Claim-The light does affect the Carbon levels because of the cycle of photosynthesis and resperation.

Evidence- One piece of evidence in this experiment is the change in carbon with a container of spinach left in light versus the dark. We found that the average change in the light container was -422. We also found that the average change in the dark container is +723.

Reasoning- This evidence supports the claim because the changes in Carbon reflect the cycle of respiration and photosynthesis. Light is an essential aspect for photosynthesis to occur, so when in light, there is a higher amount of photosynthesis. As a result, there is less carbon because photosynthesis takes carbon out of the atmosphere, thus lowering the level. On the other hand, respiration creates carbon, making carbon levels rise. So when there is no light (the dark container), photosynthesis does not occur, so the preparation takes over and creates a lot more carbon.

Does germination affect the amount of carbon produces?

# data[].attributes.body
Germination DOES affect the amount of carbon produced.

Germination DOES NOT affect the amount of carbon produced.

# data[].attributes.body
1- Put 25 dormant, germinated, and glass beans into separate containers.

2- Take the initial carbon level for each

3-Leave beans to sit for 8 minutes with a carbon detector in the container.

4-Take the final carbon level of all the containers

5-Find the change in carbon.

# data[].attributes.body
The germination does affect the amount of the CO2 because of the cellular respiration. One piece of evidence that supports this is the slope of the germinating and dormant beans. The slope of the germinating beans is 2.4, so the carbon increases, and the slope of the dormant beans is 0, so the carbon has no change. This evidence supports the claim because germinating seeds undergo cellular respiration, which causes oxygen to increase, hence the 2.4 slopes versus 0. During the process of cellular respiration, carbon dioxide is released into the atmosphere, therefore increasing the carbon levels.

2-Weigh each cup of potatoes and record the data

3-Put all 5 different sugar solutions in the cups (25 ml)

4-Leave to sit for 24 hr.

5-Weigh the potatoes again and record the percent in mass change.

# data[].attributes.body
The concentration of sucrose does affect the percent mass change in potatoes because of osmosis. One piece of evidence that supports this claim is that the water solution with a lower sucrose concentration increases mass and the water solution with a higher sucrose concentration decreases mass. The 0.2 concentration has an increase of 17.4, and in contrast to that, the 0.8 concentration has a decrease of 38.2. This evidence supports the claim because it shows the different types of osmosis which is the process of where the water is moving. One type is Hypotonic which is where there is more sugar on the inside and less on the outside. The water goes wherever there is the greater solute, so the water goes to the potato, causing the mass to increase. On the other hand, when the mass decreases, it is showing Hypertonic. This is where there is a greater solute on the outside. So when there is a greater concentration, the water goes away from the potato, causing its mass to decrease.
