GREEN GLOBS LAB

In the computer lab, double click the green globs icon that is located on the Desk Top.

Hit Shift-F3 or go to the Programs menu at the top to open the green globs program

Read the rules for a novice game under the Green Globs menu then

Start a novice game after reading the rules on the same menu

Play green globs

Write down all the equations you used to produce your score but not the ones you remove and adjust.

You may use one horizontal line (y=_), one vertical line ( x=_), and the rest have to be diagonal (y=mx+b)

Also
at least one of your diagonal lines you should tweak until it hits 3 points,
---if this is impossible consider using decimals to make adjustments to your slope or y-intercept to change the steepness or the starting point
---or if its really impossible because no three globs are close to lining up, start a new game.

at least two of your diagonal lines must be found using the process of finding the slope and solving for the y-intercept as demonstrated in class multiple times and the work for those two must be shown and attached to the print out of your lab

There is a little problem with the new version of green globs in that it does not have a print screen command under file options and so you will have to perform the following actions to show me your results.

To print the results:

1) minimize GREEN GLOBS, do not close it, and open a word document
2)change the page orientation to portrait
3) type in your name and the date along with the title geometry lab
4) go back to the green globs screen that you are trying to print and once its on your screen and ready
5) hit the Print Screen/SysRq key that is in the top row of the keyboard. This key takes a screen shot of your work which you can then paste [CTRL-V] into your open word document.
6)Go back to your word document and paste the scrren shot with your graph in sizing it appropriately to fill the space.

After you're done printing it, attach it to your worked problems and the list of equations you used to turn into me.

Half your grade will be your score, out of 40 points, the other half will be the work you turn in with it and how well you foll0wed the directions. A score of 16 is on the weaker side of average, 19 is better, 23 is superb.

Again:
to print your results you must hit the print screen/SysRq button up at the top of the keyboard, which will take a screen shot of your work. You will have to paste [CTRL-V] the screenshot into an open word document with your name on it. Don't close your green globs assignment without printing me off a copy or you will have to do it all over again.

Cricket Lab

The Snowy Tree cricket is called the thermometer cricket because you can actually estimate the temperature outside from the number of chirps you hear it make in a minutes time.

Here is some data from an experiment:

The cricket was chirping about twice a second when the temperature was 70 degrees Fahrenheit.
When it was 46 degrees out the cricket chirped an average of twenty times per minute.
When it was 50 degrees the cricket chirped an average of 40 times per minute.
When the cricket chirped once a second the temperature was recorded to be 54 degrees

Using this information, perform the following tasks and answer in complete sentences the following questions (staple on another sheet if necessary.):

1. Construct a table deciding which is the independent and which is the dependant variable in this experiment. Ask yourself, "Does the tempertaure depend on the chirping of the cricket or does the chirping of the cricket depend on the temperature?" Fill it in.
2. Graph the data labeling your x and y axis with either number of chirps degree or the degrees of temperature.
3. Find an equation that does a good job representing the relationship between the Number of Cricket Chirps per minute (C) and the Temperature (T) in degrees Fahrenheit (it is a linear relationship so you can use slope intercept form to set it up).
4. If the cricket chirps 200 times per minute use your equation to estimate the temperature.
5. Find the x and y intercepts and describe what each means in terms of the experiment.
6. Lastly, it does not make sense to graph this relationship in all four quadrants of the coordinate plane. Why is that?

General outline of Final Exam

you may print this post and not the whole blog by linking here http://rosieworkinteralgebra.blogspot.com/2007/04/general-outline-of-final-exam-1-writing.html first and then printing

1) writing algebraic equations
2) operations with rational numbers
3) catergories of real numbers
4) writing variable expressions
5) graphing real numbers on the number line
6) writing algebraic expressions
7) solving percent problems (IS over OF = % over 100)
8) Simplifying algebraic expressions
9) "
10) "
11) "
12) evaluating using order of operations

(keep in mind that -5^2 does not have the same meaning as (-5)^2. The former means the opposite of the square of 5, the latter means the square of the opposite of five. For all even powers this distinction is significant.

13) more evaluating using order of operations
14) "
15) Solving equations containing combining like terms, distributive property, fractions, ect.
16) "
17)
18)
19)
20) solving an inequality. graphing its solution and writing its solution in interval notation.
21) solving a formula for a specified variable
22) Solving a mixture problem as in chapter 2.6 ex. 7 or 8
23) graphing linear equations including possibly vertical or horizontal lines

remember vertical lines have a undefined slope ( the change in x is zero), and have no y-intercept (because they are vertical). Vertical lines have equations that have only x's in them. No y variable.

horizontal lines have a zero slope ( no change in y as they travel from left to right), no x intercept (they don't cross the x-axis, they are parallel to it) and like the x axis have an equation that when simplified simply says y=__.

24) more graphing
25) finding slopes, watch out for your negatives, that you put the change in y over the change in x and distinguish between when a result is undefined and therefore vertical or zero and horizontal.
26) finding slope
27) putting an equation in slope- intercept form (equation must be written in y = mx + b form so basically solve the equation by moving stuff around until it basically says Y = something times x plus or minus something else. The something by x will be the slope and the somethingelse will be the y intercept. Solving the equation for y is not the same as saying find the value of y or find the y intercept. In the first case, solving the equation for y the result will still be an equation but with the y on one side and the x and someother stuff on the other. In the second and third case in order to find a particalar value of y. Whether it be a y-intercept of something else a specific value of x must be entered in the equation to complete the ordered pair.

28) Finding x and y intercepts

29) writing equations of lines given either the slope and the y-intercept, the slope and a random point that the line goes through, or two points that sit on the line. In the third case you will need to find the slope and then, having found it, just like the second case pick one of the points to use in conjuction with the slope to substitute into the formula for x,y and m after which you will be able to solve for b to figure out the equation.

30. more writing equations
31. "
32. "
33. determining if the graphs or two given equations are parallel perpendicular or neither
34. solving systems of linear equations by either graphing or substitution
35. "
36. "

I will probably add a few more problems but so far this is what I have. I definetely want to add one or two about completing a table of solutions for a given equation and graphing resulting ordered pairs. I also have in mind add one relating to geometry. something with perimeter or angles like 2.6 ex. 3

I might include a bonus either about related to Interest type problem or Distance = rate times time like 2.6 ex 5 and 6

Good luck with your studies for all your finals.
