GRAPHING PRACTICE PROBLEMS Directions: All three graphs must be drawn on graph paper. Please use a ruler and be as
neat as possible. Please complete all questions in the spaces provided on this page.
Practice Problem 1: The following table shows the quantity of oxygen gas that can be obtained from the
electrolysis of various quantities of water. Draw a graph of the data, observing all the practices of good
graph construction. This includes: labeling each axis, scaling each axis appropriately, plotting the points
correctly, connecting the points, and giving the graph a title.
Quantity of water
3.0 grams
10.0 grams
18.0 grams
23.0 grams
28.0 grams
Quantity of Oxygen
2.7 grams
8.9 grams
16.0 grams
20.4 grams
24.9 grams
1. What is the independent variable?
2. On which axis will the independent variable be placed?
3. What is the dependent variable?
4. On which axis will the dependent variable be placed?
5. Predict how much oxygen could be obtained from 15 grams of water. How reliable is this prediction?
6. Predict how much oxygen could be obtained from 32 grams of water? How reliable is this prediction?

You will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. before you conduct your experiment, you need to form a hypothesis. a hypothesis is a prediction of what you think will happen in the experiment. the hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur.record your hypothesis here: record the results from step one of the experiment (dropping the objects in the air): first trial: second trial: third trial: record the results from step two of the experiment (dropping the objects in a vacuum): first trial: second trial: third trial: did the experiment support your hypothesis? using the data from your experiment, describe why you believe your hypothesis was either proven or disproven.what forces were acting on the objects dropped in the air? what force was acting on the objects dropped in the vacuum? part two: comparing forceschoose two forces and compare and contrast these forces. you must provide two ways that they are alike and two ways that they are different. you may make a list, write in paragraph form, or make a chart.choose two forces and compare and contrast these forces. these must be different forces than used in the prior question. provide two ways that they are similar and two ways that they are different. you may make a list, write it out, or make a chart.

If you answer this i"ll give you brainiest and all these points me if you do i love you 7. a doctor is at work taking care of sick patients. she spends a few minutes trying to figure out why a particular patient is sick. she taps the patient's knee to test his reflexes. while she is examining him, the patient coughs on her. a) describe the function of the skeletomuscular system in this situation. (3 points) b) describe the function of the circulatory and respiratory systems in this situation. (3 points) c) describe the function of the immune system in this situation. (3 points) d) describe the function of the nervous system in this situation. (3 points) e) describe one way that any two of the doctor's body systems worked together in this situation. (3 points)

Astudent observes a star from two positions of earth in its orbit, in summer and winter, and measures the change in the position of the star. which of these can be best calculated by this method?
