April 6, Wednesday
From yesterday and important in the future:
  1. Ideal Mechanical Advantage (IMA) = effort distance / resistance distance
    • Has no units
    • Tells us how many times a machine should multiply our effort force assuming NO FRICTION
  2. Actual Mechanical Advantage (same as MA) = resistance force / effort force
    • Also has no units
    • Is an actual measure of how many times a machine has multiplied your effort force (Takes all forces into account)
Introduced & Began Lever lab (1 sheet per group)
NOTES:
  1. Make sure you're using the metric side of your meter stick and that the locking screw is on the bottom NOT THE TOP.
  2. READ DIRECTIONS and HANDLE EQUIPMENT WITH CARE.
  3. For example, make sure your fulcrum, resistance force and effort force are at the correct locations according to the directions. Also, make sure your force sensor is at zero before beginning every portion of the lab
    • Part 1. Zero it with the hook facing up (cuz you'll be pulling down with it)
    • Parts 2 & 3. Zero it with the hook facing down (cuz you'll be lifting up with it)

March 31, Thursday
Have a calculator handy today.
Energy, Work and Power Quiz Tomorrow.
Introduced and completed the Work & Power Lab: Running up a Flight of Stairs.
Procedure & Tips for Lab today:
Before you gather data:
Weight
Mass
Gravity
Is a measure of the Force of gravity between 2 objects.
Is the amount of matter in an object.
Is an invisible force of attraction between all objects.
Expressed in Newtons. (English system uses Pounds)
Expressed in kg
Causes objects to accelerate toward earth at a rate of 10 m/s/s
Weight = mass x gravitational acc.
On earth a mass of 1 kg x 10 m/s/s has a weight of 10 Newtons. (this is equal to 2.25 pounds)


So.....
  • If you know your weight in pounds, divide by 2.25 pounds/kg to find your mass (this never changes wherever you go in the universe). Then multiply by 10 m/s/s to determine your weight in Newtons here in earth. (this would change on the moon)
  • If not, measure your mass in kg on the scale and multiply by 10 m/s/s to convert to a weight in (N)
  • The vertical distance you will move up our flight of stairs = _ meters (big open stair well; lets double check though)
  • I need 1 volunteer to help me time people from the landing
  • While climbing the stairs, stay to the inside! While going back down, stay against the wall!
After you gather data:
  • Work (Joules) = Force (Newtons) X distance (meters)
  • Power (Watts) = Work (Joules) / time (seconds)

March 30, Wednesday
Collected remaining lab sheets from yesterday (discuss)
Displayed 2nd round of work and power practice (Questions?)

Intro lab for tomorrow (time permitting)
Energy, Work and Power Quiz Friday

March 29, Tuesday
Have a calculator handy today.
Checked and covered the homework
Introduced and completed the work and power lab
Procedure & Tips for Lab today:
  • Weight is a force expressed in Newtons. Weight = mass (kg) X gravity (10 m/s/s)
  • Most of our spring scales display mass in grams and force in Newtons. Digital force sensors express force in Newtons, BUT BOTH MUST BE PROPERLY ZEROED BEFORE USING!
  • Your goal during this lab is to compare the work needed to lift, then slide a small book vs. the work needed to lift, then slide a large book.
  • Work (Joules) = Force (Newtons) X distance (meters)
  • Power (Watts) = Work (Joules) / time (seconds)

  5. Now sketch what the graphs actually do look like.
  6. Does anyone think they can achieve a greater acceleration? (walking, not running b/c of a short runway followed by a concrete wall). Try.
  7. Predict: Sketch how you think the graphs will look when someone walks TOWARD the motion sensor.
  8. Sketch what the graphs look like when someone does walk toward the sensor
    • Explain why the graphs look like this now.

What is an honors course?
"Honors course is a distinction applied in the United States to certain classes to distinguish them from standard course offerings. The difference between a regular class (such as English 1) and the honors class (English 1 Honors) is not necessarily the amount of work, but the type of work required and the pace of studying. Honors courses are enriched; they offer the same material in greater depth and with a faster pace. Honors courses emphasize critical and independent thinking to produce creative application of ideas. Motivation is the main quality that characterizes an honors student." -Wikipedia

A concise explanation of the water taste test lab:
The Chi-Square Test Result

Water Source
Expected

Difference

Essential Question: What is the probability that the differences above were due to random chance alone?
*Key Point: If the differences were due to random chance (and nothing else), we would conclude that water taste is not influenced by water source.

Our Chi-Square p-value
of 0.002 means that the
difference was probably
not due to chance. Therefore,
REJECT THE NULL HYPOTHESIS!
It seems taste is influenced by source
<
5%
(0.05)
<
If the probability is 5% or greater,
assume the difference WAS DUE TO CHANCE.
DO NOT REJECT THE NULL. It seems taste IS NOT
influenced by source.

September 14, Tuesday
Students took the Scientific Method Quiz.
Return Reaction Time Labs, and discuss briefly.
  • Present the data from Friday's lab
  • REMEMBER that the null hypothesis being tested EXPECTS that if 112 people took the water taste test and the water came from 5 sources, then about 22.4 people should favor each sample of water. REMEMBER ALSO that as our OBSERVED results get farther and farther away from that....that there is more evidence for rejecting the null hypothesis. TRANSLATION ANYONE?
  • Chi-squared calculator online. Chi-squared distribution table. Translate what the output from the online calculator means:
    • The calculator will give us a p value, which when translated literally means, "the percentage of time that a difference as large as the one we see between the Observed and Expected will happen by chance alone." And most professional scientists agree that if a difference between the OBSERVED and EXPECTED happens by chance alone only 5% of the time or less.....bingo!...reject the null hypothesis. YAY! Complicated Math can really be used to answer an everyday question like: Is water taste preference influenced by where the water comes from. Celebrate good times come on!
  • Write Experiment section (detailed, step-by-step procedure someone could follow to repeat this experiment)
    • How many people were tested? How many sources did the water come from? How was it labeled? The temperature was kept at room temperature for over 24 hours. How exactly was the test conducted in class? What data were collected? What was the purpose of using the Chi-Square test on the data?
  • Write Conclusions section
    • According to the null hypothesis, what was the expected outcome? What was our observed outcome? Does the result (p-value) of the Chi-Square test suggest that we should support or reject the null hypothesis?
  • Answer questions and submit this lab

September 13, Monday
Collect data count from Friday's lab
Discuss Scientific Method Quiz tomorrow!
  • Vocab from chapter 1
  • Written response on "Experimental Design from Start to Finish"
Students began work on the Design Your Own Measuring Device activity:
  • Introduce procedure (All measures must have 1 number after the decimal and a unit included)
  • Partners
  • Discuss
Review for Scientific Method Quiz tomorrow!

September 10, Friday
Scientific Method Quiz Tuesday, September 14
Collected experimental data sheets from the reaction time lab. I introduced the Water Taste Test Experiment
  • Question: Is water taste preference influenced by the source of the water?
  • We discussed the variables, possible hypotheses, and the experiment itself.
  • We conducted the experiment, recorded observations and collected data.
  • Students recorded the question on a piece of lined paper, wrote a detailed, step-by-step description of the experiment.
  • Monday we'll compile all data, sketch a simple graph on the lined paper, write conclusions and submit this lab.
Complete the "Nature of Science" concept map in class (time permitting)
Message from the teacher: So far I'm impressed with the efforts of all groups. If you maintain this level of work for the duration of the course, I anticipate great student success in terms of learning and high grades.
