Disney Purple Cohort

Alicia: I'm good at solving problems when they come up. I can help out my group when they are having trouble or confused with something.

Ben: I'm good at keeping the group focused and staying on the task at hand. I am also good with computers and am able to check spelling mistakes easily. I also try to pay attention to details.

Jocelyn:I am supre organized and need to get my work done A.S.A.P. I'm a pretty good artist. I am a great technical writer. I can build. I am pretty good with wiki's. I am social but pays attention so closely to details.

I'm, first and foremost, a great artist. I am also very organized (unlike some people) with my binders, and almost always know where something is. I am good at spelling and grammar, and have been known to think out of the box. I have also, occasionally, managed to make people laugh with jokes that aren't from a good joke book I own.

I feel i can bring joy to our group. I get very stressed about due dates and alwasy make sure things are turrned in on time. i wouldnt call myself clownish becuase i feel that would be innapropriate, but more so a very "giggly" student. Il make sure that these clownish kids i hear about are kept under control becuase i know peggy doesn't like that.

Alec Discussion:
I know my height is the best because i have proof mathematicly with the calulations i drew out (which are on a seperate piece of paper). I felt that we did our experimetn very accurately, precise and carefully but there definately could of been some sources of error that we didn't notice. We put 2 drops of soap into each measured beaker of vinegar. A "drop" isn't very precise because it could be a big drop or little drop, you couldn't really tell. There could have also not been the most perfect cleaning jobs each time around for the tubes, leading to some material clinging to the sides, equally not a very effective and accurate result every time. If we were to do this experiment again i would probably stick to the same steps i had for the first time, because i felt we performed it to the best of our ability and made it as accurate as possible. I did learn many things about chemical reactions such as how you can take an old experiment with different amounts of material such as the 50 g total reactants for the experiment in class, and use those results to mathematicly show what would be the best reaction for a new experiement like this one, with the 70 g total reactants.

Baking Soda/Vinegar Hypothesis(Alex, Ben, Alicia):

We think that, for the best result with only 30 grams of ingredients, we need only 2 grams of baking soda and 28 grams of vinegar.

Baking Soda/Vinegar Hypothesis (Alec, TG, Jocelyn):

We think the best chemical reaction with 30g of ingredients we will get 1 gram of bkinsda and 29g of V.

Besides being a interesting 4th of July tradition there are many chemical components of fireworks. fireworks have many colors. Also thgere are chemical components that make fireworks loud and bright. Finally there are many dangers about using fireworks.
There are different chemicals in fireworks that make them turn colors. All fireworks have salts of Copper, Strontium, and Barium. To make the rocket turn blue you add Copper plus a Chlorine producer. To make it turn purple, you add Strontium plus Copper. To make it turn red you add Strontium and Lithium. To make it turn orange, you add Calcium. To make gold you have to add incandescence of Iron or charcoal. To make yellow you add Sodium. To make green, you add Barium plus a Chlorine producer.
There are two things that make the fireworks really loud and make them colorful and shiny. First, that makes the big flash is the Aluminum or the Magnesium burning. And the loud noise is produced by the rapidly expanding gasses.
An estimated 23,200 fires in 2002 cause approximately $35 million in property loss and almost 60% of those fires occurred during the month of July, around Independence Day (http://firechief.com/awareness/dangers_of_fireworks062205/).
