Demos of leverage: 1. How to lift a person with 1 finger 2. When doing standard push ups, your body is effectively a __ class lever.
Lever lab (as a class?)
TIPS:
  1. Make sure you're using the metric side of your meter stick and that the locking screw is ON THE BOTTOM.
  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
    • Part 1. Zero it with the hook facing up (because you'll be pulling down with it)
    • Parts 2 & 3. Zero it with the hook facing down (because you'll be lifting up with it)

Energy, Work and Power Quiz Tomorrow. (*Remember: Work is done when a force is applied to an object through a distance)
This week is a Spring Break from Online Discussion (*Just make sure you're caught up for 3rd marking period)
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)
  • I need 1 volunteer to help me time people from the landing
  • While climbing the stairs, stay to the inside! While going back down, please stay toward the wall so we don't have any head-on collisions!
  • Finally, I usually only get a small number of students who achieve at least 1 horsepower. Why do you think this is?
After you gather data:
  • Work (Joules) = Force (Newtons) X distance (meters)
  • Power (Watts) = Work (Joules) / time (seconds)
  • What is your power in Watts? In English system units of horsepower?

March 27, Thursday
Collected GPE Gizmo
Checked and covered homework
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 Dec. 4th, however most of the project work should be able to be completed in class
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, Poor 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.

A question was raised recently: Does melting ice raise water level (volume)? What about the mass of the contents before and after melting?
Form a hypothesis as a testable prediction. "As ice melts into water, the volume will _ and the mass will _."
How it can be tested with enough precision on a small scale. (Demo)
Record the data somewhere in your notebook so we can compare the measurements later this period.

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.
