Introduction

1. Which of the following questions would you consider appropriate scientific questions that can be tested using the scientific method?

a. Does the pH of the soil affect the color of hydrangea flowers? Write yes or no.

b. Do hydrangeas look more beautiful when grown in the right soil? Write yes or no.

2. Read this hypothesis and answer the questions below:

Plants kept closer to windows grow larger than plants kept several feet away from windows.

a. Indicate the dependent variable:

b. Indicate the independent variable:

c. List 3 other variables that must be kept constant in this experiment (the control variables).

d. Write a prediction based on the above hypothesis.

Exercise 1.1
Take a Deep Breath

Students will need to take a picture of themselves or their group walking up and down on the step or doing other exercise.

1. Identify the following in the experimental design. You will need to refer to the protocol to answer this question.

a. Independent variable:

b. Dependent variable:

c. Hypothesis:

2. Fill in the data for each individual in your group for the Breath experiment.

Length of time breath can be held (seconds)

Individual Tested

Resting

After 1 minutes of exercise

After 5 minutes of exercise

Average (take the average for each column)

3. Look at the averages for all individuals in your group. Was the hypothesis you stated in the previous question supported by the “average data”? Explain your answer!!!

4. How many replicates did your group have? Why is it good to have more than one replicate?

Exercise 1.2
Let’s Graph

In exercise 1.1, you identified the independent and dependent variables. Which one goes on the X axis of the graph and which goes on the Y axis?

Exercise 1.3

You will need to get the data under exercise 1.3 in the protocol sheet to complete these sections.

1. What is the dependent variable?
 

2. What is the independent variable?
 
 
3. Which, if any, of these individuals has diabetes? ___A or B ___?
 
4. What data do you have to support your hypothesis?

Since this is the first lab assignments for the semester, I will not have students make graphs but students should read the information about graphing in the lab protocol and practice on their own making graphs using a program such as Excel. We will be making graphs later in the semester.
