Today's Quote:


Recap:

We spent the better part of yesterday's class working through average velocity problems in the 8th-grade classes.  I reiterated the 5 step problem-solving method as an excellent way to keep track of variables in a formula and pointed out that the Greek letter Delta
, in science, can be used to replace the phrase "a change in". The 5 step method is:

  1. Identify and manipulate the formula you are going to use.
  2. Identify the known and unknown variables in the problem.
  3. Plug your known and unknown variables into your formula.
  4. Solve the problem.
  5. Circle the correct answer and don't forget your UNITS!

We saw that velocity is simply the speed equation with a direction from the point of origin. We showed
the equation: 

Where the "ï"values are your starting numbers and the "f"values are your ending numbers.

The remainder of the class was spent working on our mousetrap cars.

In 7th grade we watched a brief clip about amphibians and then began looking at the external anatomy of our frogs in preparation of the frog dissection. Unfortunately 3rd period did not get the chance to do this due to behavior issues, however we will try again today.

Brain Bender:

In Okmulgee, Oklahoma you cannot take a picture of a man with a wooden leg. Why not?

Agenda:

8th Grade:

Quiz! Using the 5 step method, solve this problem on a 3x5 card with your name date and period on the back side and turn it in. REMEMBER to convert Km to our standard unit of METERS PER SECOND. (M/s)

A man walks 7 km in 2 hours and 2 km in 1 hour in the same direction. 

a) What is the man's average speed for the whole journey? 

b) What is the man's average velocity for the whole journey?

Today we will be working on our cars for the remainder of the period.

HOMEWORK:

Work through these practice problems and be prepared to work them on the board in class. Show your work using the 5 step method.

7th Grade

External and mouth anatomy of the frog.
 You will need to wrap your frog in plastic and label it with your names and period so we can find it tomorrow.
From this point on, you will need your goggles on AT ALL TIMES. You will receive aprons before we cut open the frog.

Aquaculture:

With subfreezing temperatures, there's not much we can do but wait. We will go outside to put the chickens out and help organize the plant area and assess the damage from the hard freeze last night.
