On the 3rd day of the Barbie Bungie Jump activity, we were to review a partner's DP and its contents. We are to critique it, and fulfill Mr. Fozi's checklist:http://wp.nc.hightechhigh.org/vfozi/2008/10/22/barbie-bungee-jump-day-3/
I decided to review Gabby's DP: http://wp.nc.hightechhigh.org/golivas/2008/10/21/barbie-bungee-jumpday2/
I was able to clearly understand the information provided on Gabby's digital portfolio.
Checklist:
-All the points are on the same graph
-The rubber bands are correctly represented on the x-axis
-The distance traveled is on the y-axis
-I was able to clearly understand the purpose of the x ad y axes.
-The slope IS between 10-40cm. [21.17 to be exact]
-And finally, you were able to solve the linear equation using the 400cm rubber bands problem.
What I learned
In this project, I was able to learn how to use equations to figure out situations on a bigger scale. Let me reiterate; we were to find the equation for our data. It was at a small scale - the barbie was dropped only a few feet up. But using the equation, we were able to find out how many rubber bands are needed to safely launch Barbie from 400 cm. It is a very handy skill to learn, and this project really helped in the learning process.
Overall, this was a very good project that helped me learn things I've never known before. Woo! Enlightenment!
Barbie Bungie Jump REVIEW
The Barbie Bungee Jump
Explanation of the experimental procedure
1. The first step of this activity is to attach different amounts of rubber bands to the Barbie (or Ken doll) in bungee-jump fashion. First, attach 2 rubber bands, then 4, 6, 8, and 10.
2. The doll was dropped from a certain marked point.
3. Once the doll is dropped, the group was to find the lowest point the doll reaches when dropped.
This scatter plot shows the results of the experiment.
In this diagram, the y-axis represents the distance the doll traveled from its initial point (in centimeters).
The r-value shown (.99) is a representation of how close the line-of-best-fit is to the actual points. The line of best fit is a straight line that is as close to all the plots on a graph as possible. The closer the r-value is to 1, the closer the line of best fit is to the plotted points.
The slope of this equation is as follows: y=21.17x + 33.27
Predict the number of rubber bands needed for Barbie to jump from a height of 400 cm.
To answer this question, simply input 400 cm into the y of the equation, because the y value represents how high the drop is.
Once completed, the answer I've come with is about 17 rubber bands.
This means that Barbie can safely bungie jump with 17 rubber bands from a height of 400 cm.

Spirit Week Update
Haven't been posting much lately, in lieu of 3 different projects due on the same day. But that's aside the point. This week was spirit week, and everyone was encourage to show their school spirit by dressing up accordingly.
Mix-match Day
Diamante and her mix-matching.
70's Day
Mrs. Howard/ Miss Fisk and their grooovy loook maannn
Mrs. Rojas/Mr. Acker as Sonny and Cher
There was also a Favorite Actor's day where everyone dressed up as their favorite actor, but unfortunately, I didn't have my camera on me. But I was lucky enough to get some of the Community Meeting.
Crowd gathered
Quick Announcements from Harrison, Katherine, Kendalyn, and Izzy
A few from Mrs. Howard
And then our host, Mrs Clark
Miss Fisk, Mrs. M, and Mrs. P bein...cool?
Devil Sticks w/ Rein
Here Comes the Sun, performed by Hannah/Kayla
The Main Event, the Fame SIG
Disturbia dancers
Mark/Katie
Then Everyone!
College Night with Chris White (and JUMP!)
Chris White introducing the event
Chris explaining the importance of extra-curriculars.
Even with a high GPA, you still have lesser chance than someone with more extra curriculars, and lower GPA than you.
There were much more people than expected, so Nikki moved everyone out to the deck.
The gist of it: start clubs, have extra-curricular activities, and make sure the colleges know about these. Mention them in applications, interviews, etc.
After the whole presentation, some of us wanted to have some fun. So of course, we jumped.
It was a fun day.
One of My Best Shots In a Long Time
Today during SIG, yearbook photog. needed to take pics of High Tech High's habits of heart and mind. Once we finished with that, we decided to have a little fun with it.

Forrest really helped out with this one, getting everyone in the right places. Once everyone was down, I went up to the roof and shot away. This is actually 3 pics stitched together to make a mini panorama. Probably my new favorite shot.
Other than that, Jordan/I took a panorama of the construction of the new school.
The a bit of fun during lunch
