Breakthrough New York: Physics Final Project "Science walks forward on two feet, namely theory and experiment. Continuous progress is only made by the use of both - by theorizing and then testing, and then bringing the theoretical foot up and pushing it beyond.” -Robert Millikan, Winner of the Nobel Prize in Physics, 1946 Over the next four days, you will be responsible for re-testing one of the labs that we have already done to push your experiment and conclusion further. You will be following through with re-running the experiment, just like you have described in your conclusions throughout the summer. You will be responsible for following all steps of the scientific method. By celebration, you will have written a full lab report and created a tri-fold board presentation of the lab. Day 1: Background research, scientific question, and hypothesis Day 2: Create procedure, list of materials, and data tables Day 3: Execute procedure, discuss and analyze results, begin working on conclusion Day 4/5: Put together the lab report and poster We have completed a total of 4 lab exercises this summer. You will be assigned to retest one and will be required to complete all work in groups. Groups will be assigned on Day 1 of the project. Write your personal assignment below.

Day 1: Background Research, Scientific Question, and Hypothesis

Today you have 3 main objectives: 1. Perform background research on your lab exercise. 2. Propose a scientific question based on this research. 3. Propose a hypothesis using if…then…because format.

Objective 1: Background Research As scientists, we need to look at existing research on our topic of interest prior to generating a question about that topic. After all, our curiosity stems from somewhere – that somewhere is preexisting research. Step 1: Revisit the lab you are re-testing.

• Review the lab’s scientific question, hypothesis, procedure, data, and conclusion. Does anything strike you as interesting? Frustrating?

Could you have pushed your thinking further? If so, how?

• What were the main sources of experimental error in this lab?

How it affected the lab What can you do to limit this error (must be feasible!)

Source 1:

Source 2:

• What were the “next steps” you listed in your conclusion?

• What would you like to change in this experiment? Reasons for change: Scientists have many reasons why they might change things in an experiment. Some are listed below.

1. Include a new variable or condition (a question that may have arose during the course of the experiment)

2. Change the way the procedure is executed in order to limit experimental error

3. Increase the number of trials to obtain more accurate data 4. Change the way data is presented (ex: use a graph) to make it more clear 5. Other reason (write this in the table if you select this option)

Change Reason for Change (number from

above or write in your reason) Feasible/Infeasible

Objective 2: Scientific Question The scientific question should be based off of the background research you just performed. After filling out the table, your question might change. If there is a number 1 in the “reason for change” section, you might want to revise your question. Otherwise, keep the question the same. Write it below: __________________________________________________________________________________________________

Objective 3: Hypothesis Propose a hypothesis to your question, based off prior research, your previous experience with the lab, and your understanding of physics concepts.

• If the reason you are changing the experiment is number 1 (see table above), then you will need to write a new hypothesis.

• If your hypothesis was not supported the first time you conducted the experiment, be sure to revise it using your knowledge of physics concepts.

• Remember to use If…then…because… format. Write your hypothesis below:

Day 2: Create Procedure, List of Materials, and Data Tables There are 2 main objectives for today:

1. Create the lab procedure. 2. Form a list of materials. 3. Decide how you are going to present your data.

Objective 1: Create the lab procedure

• Look at the procedure of the lab you are re-testing. Decide which steps you would like to change. Write in the new procedure below and mark an changed steps with an asterisk (*).

• Indicate how you will collect data in your procedure by outlining exactly what the experimenter should do to record data (i.e. fill in data table, create graph).

Write your revised procedure below. If you need more room, feel free to write on the back of this page. Be sure to mark changed steps with an asterisk (*). 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.

Objective 2: Form a list of materials

• Examine your procedure and write down the materials that you will need for your lab. Include quantities. We will have these materials available to you tomorrow, but if there is something that you need that you do not put on this list, we will not be able to get it to you.

7. ________________________________________________________________________________________________

8. ________________________________________________________________________________________________

Objective 3: Present data

• Consider your hypothesis, and try to determine the easiest way to present the data, so that it is easy to support or reject the hypothesis.

• Draw any data tables and/or graphs necessary. The data tables should be empty, and the graphs should have a title and labeled axes.
