Illinois Valley Toy Car Company is Illinois Valley Toy Car Company is looking for a new toy car design. The looking for a new toy car design. The company wants a car that will reach company wants a car that will reach the fastest velocity and that is made the fastest velocity and that is made out of recycled material. Your job is out of recycled material. Your job is to come up with a prototype for this to come up with a prototype for this company. company.

Work Sample ChecklistWork Sample ChecklistWork Sample Lab Write-Up Guidelines Title Page Forming the Question:

1. Give a specific scientific question. Use science words. a. What is the effect of ______________ on _____________? b. How/To what extent does the _____________ affect _____________? c. Which/What _______________ do/makes _____________________? d. You can use other words but make sure it sounds right and actually asks a scientific question. e. Make sure you cover what your variables are. What you are changing and what the

measurable outcome is. 2. Background information

a. Ask questions about your lab. Find answers. b. Write in paragraph form answer questions about lab. c. You should know the outcome of your lab from your background. d. All of this has to be scientific. No common language. But make sure it makes sense.

3. State the variables: independent, dependent and control. a. Independent: changed variable b. Dependent: observed outcome c. Control: other variables you control.

4. Hypothesis: Answer question fully. Should be a scientific answer. Don’t state facts from past. Don’t change it after experiment.

5. Prediction: What you think will happen? Designing the Investigation:

1. Materials (list) a. Just make a list b. Include how much of each you will need.

2. Procedures (step-by-step) a. Include how much stuff you use. b. The point is to be able to replicate your experiment. If I read it and don’t know how to do it,

than you need to fix it. c. Have someone else read your instructions. When they no longer have any questions you can

consider your procedures done. 3. Safety:

a. Chemical safety b. Fire safety c. Water on the floor safety d. Technology: If you used a machine or computer or anything let me know.

Collecting and Presenting Data: 1. Chart of observations or table. Needs to include everything you are measuring. Also include a title

and a little information at the bottom telling me what is in the table or chart. 2. Manipulated data: averages 3. Graph of data. Needs title, x axis title, y axis title, key or legend. Using color to distinguish lines or

bars is a good idea. 4. List of chemical reactions:

a. Needs to be accurate. If you are not sure check with someone. Needs to be balanced. Analyzing and Interpreting:

1. Restate question above. Exactly how you have it in the forming the question section. 2. Explain what happened scientifically. Has to be clear. Connect everything your question,

background, hypothesis, and data. Use your data to explain your outcomes. 3. Relate explanation to question and data collected. 4. Sources of error and bias. You have to list something. NO ONE is perfect. You had some error and

you need to explain it. It also has to be something that actually would affect your experiment. 5. Provide support for outcomes. Conclusion. Restate everything in three sentences. Tell me what

happened, what data supported your outcome and explain how the errors impacted outcomes.
