TFAD

OPENING QUESTION: The very most important part of your TFAD project is 'the hook' that we discussed yesterday.

What is YOUR hook and how will you use it to 'grab' your students attention and engage them in that one single thing you need them to learn?

Please discuss with your team!

LEARNING OBJECTIVES: I will begin work on my Orbital/Circular Motion Teacher For A Day (TFAD!) project.

WORDS O' THE DAY:

  • Centripetal ("towards the center")
  • Centrifugal ("away from center")
  • Gravitational Constant: G = 6.674 × 10-11 Nm2/kg2
  • Period ("Time to complete one orbit")

FORMULAE OBJECTUS:

  • T2 ∝ A3: The square of the period (in years) of an object orbiting the sun is proportional to the cube of the average distance to the sun (in years). This is kind of archaic in that we rarely see the proportional symbol anymore.

  • T2 = a3: The square of the period (in years) of an object orbiting the sun is approximately equal to the cube of the average distance to the sun (in years). We MUST keep in mind this is an observational relationship. Although it gets us close (in most instances) it is not an exact value so the "=" sign isn't really appropriate although it is widely used.

  • MsT2 = a3: This version is still approximate but it allows us to substitute in the mass of *other* stars as long as we measure the mass of the other star in terms of the mass of the sun being 1.00

  • T2 = (4π2/GM)(a)3 = This version is much more accurate is often referred to as Newton's version of Kepler's Law. Notice ALL values must be in SIU

    • v2/r: centripetal acceleration
    • mv2/r: centripetal force
    • Fg = Gm1m2/r2: This is Newton's famous equation for gravitational attraction. The gravitational force between objects is found by multiplying the mass of each object by the "G" the gravitational constant divided by the square of the distance between those two masses in meters (square). Oddly enough, gravity is a very, very weak force. A simple bit of friction here on Earth causes objects to NOT be drawn together....we'll discuss at length

WORK O' THE DAY:

Let's discuss.

I know you aren't seasoned vets, but sometimes that's a very good thing. You get to bring your own 'take' to teaching.

Here's your chance to be the teacher that best engages you in new learning.

Keep in mind that standing and delivering is only effective to a point--- and your lesson plan should engage only in the barest minimum of that.

Similarly, worksheets and other 'daily work' are probably a no-no.

You will be graded on how well you address each of the lesson plan aspects:

Opening Question: (You'll use that to get your students thinking about that one topic you need them to learn. This works best when you can tie it to your student's day-to-day lives in some way)

Learning Target: (That one topic you want your students to learn during your lesson. It should be written in student friendly language... "I will be able to..."

Words O' The Day: (No more than 3 key vocab terms essential for understanding your topic)

Work O' The Day: (This is where you deploy your Hook! It is the main part of your teaching program and should take between 75% - 85% of your lesson)

Concluding Task: (How will you know that your students have learned what you need the to learn? Or how much of what you want your students to learn has actually stuck?)

Key aspects to that will be how well you:

  • Employ Originality
  • Demonstrate Creativity
  • Demonstrate Effectiveness in getting your learning target across to your students
  • Avoid paragraphs of text.
