In your experiment, which marble went the fastest after collision? Which marble went the slowest?
What about your data supports your claim?

Look at your progress report. Write down the sections you will revise to improve your grade.
I can synthesize the findings of all the lab groups in the first lab experiment.
I can write my lab conclusion.
I can ask questions of other groups in order to better understand their findings.
I can participate in a class discussion about the relationship between mass and movement.
I can evaluate the structure of my lab report to improve it for next time.
I can review my grades for the first lab report.
I can revise my first lab report.
I can create a title and TOC entry for the first lab.
I can describe the structure that will be used for lab reports moving forward.
How do we finish the "data" step?
- Make sure your data table is complete. Cut it out and glue it into your lab notebook.
- Create a graph (IV on x-axis, DV on y-axis). Cut out and glue into lab notebook.
- If you are not on step 7 yet, make sure you leave plenty of space to finish the parts in between before gluing in step 7.
How do we write a conclusion?
- Restate your hypothesis
- Make a claim (was your hypothesis true, false, or inconclusive?)
- Use data from your experiment to support your claim (how fast did each marble go? which was fastest? slowest?)
- If something odd happened in your experiment, this is also the place to give possible explanations for what happened (human error, problems with experiment set-up, equipment malfunction, etc.)
- End with a statement of your findings (We can conclude that ... )
This should be written in paragraph form
What did we discover in our lab?
Were the patterns in the data the same in all groups? If not, why might this have happened?
What was the original purpose of this experiment? What phenomenon were we exploring?
Why did we use the ramp instead of rolling the marbles by hand?
When in the experiment did we see balanced forces? Unbalanced forces?
How did energy flow through the marble-ramp system?
How did the experiment provide evidence for why all baseballs must be the same mass in Major League Baseball?
DAY 2
Let's create a TOC entry for Lab 1!
Checkpoint 1: Question, Research, Hypothesis
- Make sure question has question mark
- Make sure research has bullets or numbers
- Make sure section headers follow guidelines
- Make sure I can read your handwriting
- Do NOT write on the back of pages or doodle in your notebook
Hey Finn, how do we create section headers in lab write-ups?
Checkpoint 2: Experiment Summary
- Written as a paragraph
- First sentence summarizes the experiment very briefly (For our experiment, a marble rolled down a ramp that will collide with a marble of varying mass to see the resulting speed of the marble that is hit.)
- Next section states independent variable, dependent variable, and constants. Make sure these are labelled!
Checkpoint 3: Materials and Procedures
- List of materials must be vertical
- Procedures must be numbered steps
- Materials and procedure must be comprehensive (every material is included and every step is explained)
Checkpoint 4: Scientific Diagram
- Must be at least half a page in size
- Should clearly show experiment set-up (multiple angles may be required)
- All materials should be labelled with arrows
- Should be neat and carefully drawn (might consider drawing on another sheet and gluing into notebook)
Checkpoint 5: Data
- Data table should be glued in and complete (neatly)
- Graph should be glued in and complete
Hey Finn, how do we make a graph? (IV on x-axis, DV on y-axis)
How do we turn in our notebooks for regrading?
- You can only turn it back in once (by Friday)
- You must mark each thing to be regraded with a post-it note that sticks out of the notebook
Homework
If you need to complete parts of your Lab 1, you can finish those at home on a separate piece of paper and glue them into your lab notebook for regrading. Take a picture of your work so far if needed.
