  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. (For example, a resistance distance of 40 cm DOES NOT mean the weight needs to be hung @ the 40 cm mark)
  4. Also, make sure your force sensor is at zero before beginning every portion of the lab

Energy, Work and Power Quiz Tomorrow. Work and Power Discussion (due Thursday)
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 22, Friday
Collected GPE Gizmo
Checked and covered homework from Wednesday
Covered CH 5&7 Notes through "Power." (Demo of lifting a known mass)
Introduced and completed the work and power lab (as a class?)
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)

Group Periodic Table (Group) project work and presentation (Groups of 2 or 3 maximum) *due date Wednesday 1/2/13, however most of the project work should be able to be completed in class by Friday 12/21
Grading Criteria Checklist:
  • The presentation is creative (Overall layout, images, text are visually appealing)
  • The presentation includes several effective supporting images.
  • The presentation effectively summarizes the group characteristics (for your particular group of elements)
    • 1 image must show or highlight where your group lies on the periodic table
    • 1 image must be an atomic model/diagram of an atom of one of your elements
    • 1 image must be a complete chemical symbol of an atom of one of your elements
      Complete_Chemical_Symbol.png
  • The presentation includes info on specific elements within your group (Similarities and differences)
  • The presentation is focused (remains on the subject)
  • The presentation flows smoothly from one idea to the next
  • The information (text, images, video etc.) is(are) accurate, clearly visible, concise, yet effective (Include a sufficient amount of quality material in en effective manner without drowning the viewer in paragraph after paragraph of text on the screen)
How do I begin?
  1. Decide who you will work with and which group of elements you want to focus on. If there are conflicts, we'll draw to determine who gets a particular group to work with. (Possible choices include: Alkali Metals, Alkaline Earth Metals, Transition Metals, Basic Metals, Metalloids (a.k.a. semi-metals), Nonmetals, Halogens, Noble gases, Lanthanides, and Actinides) We will work in groups small enough to cover each group of elements and obviously each group of elements can only be used once.
  2. Once topics are assigned, login onto a laptop and sign into your school Gmail account.
  3. Create a new Presentation, Share it with each group member using his or her school emails and myself mchughc@nasdschools.org
  4. Begin working on the project. *Note: there will be some class time to work on the project between now and the due date, but you may need to spend some time outside of class completing the project if your group needs additional time.

Key items and safety for the lab today:
  1. Follow all verbal and written directions!
  2. If your computer is uncooperative, immediately inform me and continue lab with a plain, old thermometer
  3. Hot plates are potentially dangerous! The only thing on a hot plate should be a beaker. (Keep chords and everything else out of the way!)
  4. Computers do not like water and water and electricity do not mix! This lab is setup specifically to prevent accidents. Keep your computer away from the hot plates and beakers of water!
  5. Not following directions and/or horseplay will result in a zero grade for this lab and possible disciplinary action.
Take some boiling water from the first group done with the lab, place into a test tube, begin to graph it's temperature, lower the tube into a salty ice water mixture and stir until the test tube water freezes.

Returned and covered Density and Metric Quiz (overhead key)
Brain Pop Cartoon "Temperature" (2:37)
Eureka video on temperature -----> Covered a couple of temperature conversions on overhead. *Please note: a formula itself does not limit the precision of a calculated answer. For example: You use a Celsius thermometer to measure the temperature of boiling water as 100.0 degrees Celsius (4 sig. figs.). You then convert to Fahrenheit using the formula F = 1.8(C) + 32 and your calculated answer is 212 F. You are tempted to write 210 F as your final answer because you are aware of significant figures and the rules for rounding. However, the 1.8 from the formula to convert Celsius to Fahrenheit DOES NOT limit your answer to 2 sig. figs.! "Why the heck not you ask!?" Because in this case 1.8 is not a measurement, it is simply part of a formula that is used for conversion. The rules for sig. figs. and rounding your calculated answer only apply to measurements themselves. This is because there is always some estimation involved in measurement and as we already know, the precision of our measurements is determined by the device we are measuring with.

September 4, Tuesday (Periods 1 - 4 are 30 min.)
Quote of the Day: "A short saying often contains much wisdom." I begin class each day with a quote or a question on the board; just some food for thought.... maybe something to talk about. Anyway, it's a good idea to write some of them down in your notebook or somewhere, since you can earn extra credit by remembering them on quizzes and tests!
Attendance (during meet & greet activity), Welcome, and Fire Exit Procedure
  • How many of you love to get stuff for free?
  • What would you say if I offered you a bunch of cash for free!?
  • How much $ do you think NASD spends per student each year?
  • Our district website. (Please pay particular attention to the final figure at the bottom)
  • I'm going to continue to try my best to give you your money's worth!
  • With that said, Learning is an active process. People learn in different ways, and at different speeds, etc. but I think we can all agree that we generally learn more effectively when we are actively engaged in the process. What is the best way to acquire KNOWLEDGE? Information is everywhere, I'm asking about knowledge (Censor/Bleep 2nd vid. @ 2:45)
