This is a lab for science can you help with punctuation errors? Also where it says figures I have pictures :) (I am in 7th grade btw so no hate)
Leaf lab
Purpose: Find out if the leaf area of a given tree is bigger on the North or the Southside. Learn more advanced statistical analysis.
Research: To find the area of an irregular shape it’s whole + part ½ which is whole plus part divided by 2. The shape of the leaf will be traced. They are affected by the Earth's tilt and the sun because we are in the North Hemisphere.

Figure 1 is an example of the Earth’s tilt and how the sun gives a certain amount of heat to different parts of the Earth.
The south gets more sun it’s because the leaves burn while the north leaves get less sun. The north leaves are thinner but bigger in area than the leaves that get a lot of suns. This makes them smaller or bigger because one side might get more sun which makes north leaves bigger.
Hypothesis: The leaves on the Northside are bigger.
Procedure:
1. Collect 35 leaves from the Northside and 25 leaves from the Southside.
2. A tree that is not in shade.
3. Press the leaves flat.
4. Trace the leaves onto graph paper using both sides of the page keeping North and South separate.
5.Count whole (w) and partial squares (p) and calculate the area of each leaf in squares 6. with the equation A= W+ ½ P.

Figure 2 is an example of the equation A= W+ ½ P. There are 4 whole´s and 8 parts so the area is 8 inches squared because 4+ ½ 8= 8.
7. Create a north and South leaf data table.
8. Discard leaves afterward.
9. Put the leaf area in order from smallest to greatest in each table.
10. Find the mean, median, mode of the 2 data sets as well as the entire range of 50 leaf data sets.
11.Create a histogram
Use the range to find the size of 7 bins. USe the nearest whole number
Sort leaves
Count leaves and creates a chart
12.Create histograms of individual data using Microsoft Excel or google docs
5. Results: The north's side leaves are bigger than the south side by a few a lot,
6. Conclusion: It was a warm sunny day and windy. The experimenter gathered 25 leaves from the North and South sides with all different sizes and colors. The hypothesis was supported based on the data collected. One reason why it was supported was that the North overall average was greater than the South. The Northside leaves are greater is that it is proven by facts. If someone compared a random south leave to a random north leaf, most times the North would be bigger because the probability of getting a big leaf is higher for North rather than South. The second piece of evidence from my data is that the South bin had more leaves in smaller bins while the North bin had an equal amount of leaves in the high and low bins. The third piece of evidence is that the Northside leaves had a bigger average than the South leaves. Also, the Southside had the smallest leaf while the Northside had the biggest leaf. The entire group also supported this.
7. Errors and ways to improve: Try to get different trees and instead of picking a few leaves in a certain area in the north and south, pick random ones. Also, gather more and different leaves. Different weather conditions could affect the leaves.
Figure 3, is the north bin where most of the leaves are bigger.
Figure 4, the south bin where most of the leaves are smaller.
Figure 5, the class north bin where some most leaves are small but some are big.
Figure 6, the class south bin where mostly all of the leaves are small.
Figure 7 is the tree used to pick leaves off.

Answer:

First of all you should give more then 5 points for this.And the errors are you should add a space between all of the steps and info of the lab. And read everything over again and where you take a breath at or if you stop add a coma or a period.

Water boils at 100°C and turns into steam. Which similarities or differences are there between water in these two states? (1 point)

The particles will have more space between them and will be moving at higher speeds as steam.

The particles will have more space between them as steam, but they will be moving at the same speed in both states.

The particles will have more space between them as a liquid, but they will be moving at the same speed in both states.

The particles will have more space between them as a liquid, but they will be moving faster as steam.

There are several ways to model a compound. One type of model is shown.

4 C's are connected in a line by 3 black lines. The C on the left has 3 H's attached to it each by a black line. The next C has 1 H attached by a black line and 1 O attached by 2 black lines. The next C has 2 H's attached to it by 1 black line each. The last C has 2 H's attached to it by 1 black line each and 1 O attached by a single black line. That O has an H attached to it by 1 black line.
What is the chemical formula for the molecule represented by the model?
