February Inquiry Day

By now, each group is fully in the data collection phase. Your procedures were finalized last semester so please stick with the steps you wrote. When you go into the field, you should have the following:

• Procedure - don't leave anything out!
• Data Tables - record your data as you collect it. Record your data directly into your data table. Each time numbers are transferred, there is a chance of making a mistake so please write directly into the table. This also allows you to have all of your "original" data in one place.
• Photo-taking device - How are you capturing the story? Collecting data in the field is more than just the numbers you measure. 
• An idea of the story you will tell - How will you present your data? What will be the story?
• Question/wonderings - Where are you recording this information?

Today's Goals

1. Collect data - by now your group should be able to get this done within 45 min - 1 hour
2. 1:15 - all groups back in the class
3. Update wall space
4. Update electronic data tables
5. Write-up today's story
6. Discuss data trends. What are you noticing about your data so far? Is your data supporting your hypothesis or not? What are you not so sure about? What else do you need to do?

Groups:

	Dr. Leaf
	Dust How does the quality of air change through out the year?
	JArs of light science
	Soiltologists
	The Owl Observers How Does The Water In The Pond Changes Throughout The Year
	The Pond
	The Raindrops How does the pH in rainwater change through out the year?

What is a force?

Since last class, you have read about forces (unbalanced and balanced) and different types of forces. Today, we will continue with our historical journey. What does Newton have to say about forces?

How can forces be measured? Using a spring scale...


What ideas is the creator of this music video trying to get across? Did it work?

Next Class: Inquiry Day!

Historical views of force and motion

Thanks to the students who are coming in to reassess! I appreciate your efforts. Please remember to schedule an appointment by filling out the form in the side-bar.

Today, we will begin with the question set we did not get to yesterday:

The remainder of the class will be dedicated to "meeting" three historical figures: Aristotle, Galileo, and Newton. What were there thoughts on force and motion?

For next class, please read pages 41-47 in your Motion and Forces text. Answer questions 1-6 on page 47.

Speed & Position Wrap-Up

Welcome back to AST! I hope everyone had an enjoyable break. Before you left, we took an assessment on concepts related to position and speed. Today, you will do the following tasks to get your mind thinking about these topics again:

Tasks:

1. Review the assessment with your group members. Discuss the strategies that each of you used to solve the problem. If you did not correctly answer a question, rework it on another sheet of paper. For each incorrect question:
1. Identify what was incorrect.
2. Describe why this was incorrect.
3. Correctly rework the problem.
2. On a whiteboard, create a diagram and a phrase that distinguishes between each set of ideas: (Note - please organize your whiteboard in a way that gives enough space for each of the 5 ideas.)
1. Interval of Time vs Instant of Time
2. Position vs Change in Position vs Distance
3. Position vs Speed
4. Average Speed vs Instantaneous Speed
5. Acceleration vs Speed
3.

Making sense of graphs

Today, you and your partner will analyze a series of graphs. What story does each graph tell?


You will receive 5 graphs similar to the one above. On an A3 paper, arrange the graphs. Describe the motion in each one:

• Is it constant? 
• Does it change? 
• Between each meter interval, where is the speed?
• What is the speed?

Dimensions

Not quite what we are discussing right now but check it out.
