 * April 7, Thursday**

Introduced & Began Lever lab **(****1 sheet per group**) NOTES:
 * 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**
 * 1) **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)**
 * 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)**

**Have a calculator handy today.** Introduced and completed the Work & Power Lab: Running up a Flight of Stairs. Before you gather data: After you gather data:
 * March 31, Thursday**
 * Energy, Work and Power Quiz** **Tomorrow.**
 * Procedure & Tips for Lab today:**
 * **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!**
 * **Work (**Joules**) = Force (**Newtons**) X distance (**meters**)**
 * **Power (**Watts**) = Work (**Joules**) / time (**seconds**)**

**Have a calculator handy today.** Checked and covered the homework Introduced and completed the [|work and power lab] Students began Practice Work and Power [|Problems sheet 2]**(this is homework for Thursday)**
 * March 29, Tuesday**
 * 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**)**

 * 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 || Observed || Difference ||
 * 1 || 22.4 || 17 || 5.4 ||
 * 2 || 22.4 || 25 || 2.6 ||
 * 3 || 22.4 || 24 || 1.6 ||
 * 4 || 22.4 || 36 || 13.6 ||
 * 5 || 22.4 || 10 || 12.4 ||
 * 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.** ||

Students took the **Scientific Method Quiz.**
 * September 14, Tuesday**
 * 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
