Place filter in 4 Petri dishes.
Measure and add 5, 10, 15, and 20 milliliters of water to each dish.
Place 10 mung beans evenly spaced in each dish.
Put them on a window sill for 72 hours.
Record results.

The amount of water does affect the number of seeds that germinate in a 72 hour time period. To start, the 10 mL of water had an average of 8 seeds germinated, while the 5 mL only had an average of 1.3 seeds that germinated. Additionally, the fact that their error bars don't overlap is statistical proof that the water matters. This evidence illustrates the fact that the amount of water does matter because the water expands the seeds. Furthermore, more water delivers more oxygen to the seeds, and activates enzymes for respiration. This provides energy for growth.

Does the amount of water in the chamber affect the amount of isopods?

Procedure

js28062 — 2024-08-29 18:33:40 UTC

Place filter in each side of the test area.
Put water on one side, and leave the other side be.
Place 5 isopods on each side of the test area.
Record how many go to either side in 1 minute intervals for 10 minutes.
Record results.

Hypothesis

js28062 — 2024-08-29 18:35:10 UTC

The more wet chamber will attract more isopods.

CER

js28062 — 2024-08-30 18:06:20 UTC

The isopods show little to no preference to the wet and dry climate. To start, the data table shows that the isopods were very evenly distributed between the wet and dry climates. Additionally, the error bars are very even and overlap. Therefore, there was no statistical difference between the wet and the dry.

Does the tempature of the chamber affect the number of isopods?

Hypothesis

js28062 — 2024-08-30 18:22:36 UTC

The warmer chamber will attract more isopods.

CER

js28062 — 2024-08-30 18:27:19 UTC

The tempature of the chamber does affect the number of isopods. At the end of the experiment, the data tabe shows that the number of isopods in the hot chamber was 9, while in the cold was 1. Isopods cannot survive in the colderr cliamte, so they are morea tytarcted to the warmer tempature.

Does the type of water affect how much the duckweed will grow?

Hypothesis

js28062 — 2024-09-18 18:48:26 UTC

The type of water will affect how much the duckweed grows.

Procedure

js28062 — 2024-09-18 18:52:08 UTC

Fill 4 cups with 125 mL with saltwater, tap water, pond water, and filtered water.

Plant 10 duckweed in each dish.
Wait 9 days
Record results

CER

2024-09-27 17:50:26 UTC

The type of water does affect the growth of the duckweed because of the amount of nutrients in the water. To start, the saltwater and filtered water did not reproduce, and the tap water went up by only one. However, the pond water went up by 6. This evidence shows that the type of water affects the growth of duckweed because it shows how the different types of waters have different amounts or types of nutrients that cause the duckweed to either reproduce and thrive or not reproduce at all and die.

How location relative to the water in Community Park affect biodiversity of the bugs?

Hypothesis

js28062 — 2024-10-02 17:58:00 UTC

The location of the bug traps will affect the biodiversity of the bugs.

Procedure

js28062 — 2024-10-02 18:01:31 UTC

Find 2 locations to place the glue traps.
Place the glue traps.
Wait 24 hours and then check the glue traps for bugs.
Record biodiversity.

CER

js28062 — 2024-10-02 18:01:50 UTC

The location of the bug traps relative to the water in Community Park does affect biodiversity of the bugs. To start, the richness and abudance of each trap vary. For example, the hill's richness is around 5, and the marsh's and bridge's are both around ten. Furthermore, the Simpsons Diversity Index of the bridge is 0.75, the hill is around 0.5, and the marsh's is around 0.85. This evidence illustrates the fact that the location of the bug traps does matter because closeness to the water enhances biodiversity because these areas usally provide resources such as moisture and food. The marsh likely creates a more hospitable environment for various bug species compared to the drier hill.

Does germination affect the amount of carbdon dioxide produced?

Hypothesis

2024-10-31 18:14:58 UTC

Germination will increase/decrease the amount of cardon dioxide produced.

Procedure

2024-10-31 18:34:29 UTC

Set up bottle with germinated seeds, dormant seeds, and glass beads.
Measure the carbon dioxide levels of each
Record data

CER

2024-10-31 18:41:49 UTC

Germination increases the amount of carbon dioxide because of cellular respiration. To start, the germinating seeds had an increase of 132 PPM, while the dormant seeds had a decrease of 37 PPM. Furthermore, the glass beads had a decrease of 20. This evidence illustrates the fact that germinating seeds increase the amount of CO2 because the dormant seeds don't have respiration. However, the germinated seeds area actively growing and making new cells, which outputs carbon dioxide.

Does the concentration of sugar water affect the percent mass change in potatoes?

Hypothesis

2024-11-26 19:18:21 UTC

The concentration of sugar water will increase/decrease the mass change in potatoes.

Procedure

2024-11-26 19:21:38 UTC

Measure the weight of 3 fry-shaped potatoes.
Put each in 5 dixie cups.
Put 0, 0.2, 0.4, 0.6, and 0.8 concetrations of sugar water in each, respectively.
Wait 24 hours.
Record data.

CER

The concentration of sugar water affects the percent mass change in potatoes because of osmosis. To start, the graph shows that the potatos increase until the 0.4, and after that it exponentially goes down. This is because of osmosis. Osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water.

The amount of light does affect the carbon dioxide levels in an air-tight container with spinach because of respiration. In the graph, it is shown that the CO2 goes up by almost 750 when there are leaves in the dark, compared to when there are no leaves in the dark. This is because of cellular respiration. The leaves are creating new cells, and by doing that they let out CO2.
