I didn't do this project because i wasn't at school i had to go to work on Tuesday and Thursday.
The days i was there i wasn't in a group so i just watched. and the only project that i watched present was Eric and Al they made the light turn on by rolling a ball and burning rope.

1. The protein that you eat get digested by your body. So the food if broken down. then its sent into the blood stream. Then it build your muscles.
2. The bowl of pasta gives you energy because its a carbohydrate. Carbohydrate are made up of sugars. when sugars break up they give you energy.
3.Our bodies need to eat fat so we have more protection, stores energy, insulates, cushions

The five types of reactions are Synthesis, Decomposition, Single Displacement, Double, and Combustion.
Synthesis- Two or more substances combine to form another more complete substance
Decomposition-opposite of synthesis
Single-Displacement- occurs when one element replaces another element in a compound
Double- Displacement- Two different atoms in two different compounds exchange places.
Combustion- A hydrocarbon reacts with oxygen.
Synthesis- fe + o2 ---> Fe2O3
Decomposition- NaHco3 ----> H2O + CO2 + NNaoH
Single Displacement- Fe + Cuso4 ---> Cu + Fe(So4)3

Some metal ions can be identified by the color of their flame test. Different elements placed into a flame will turn the flame a different color. What metals do colors indicate. For that lab we used a piece of wire and some elements and we used a flame we saw what color the element would turn in the flame.
Chemical Formula Name of Metal Color Produced
Kno3 Potassium Lavender
Cocl3 Cobalt Sparking Orange
Mgcl Magnesium Blueish Green
Ba(no3) Barium Yellow Green
Mncl Manganese Orange Yellow
Cucl2 Copper Teal Green
SR Strontium Bright Red

- you have to wash the wire that the chemicals go on or the colors wont come out like they are suppose to.
- It wasn't that hard but it was a little bit difficult going around to each element putting them into the flames.
- You Would have to have more then one.
- The flames were produced by putting the elements into the flame.
- Strontium, Cobalt, Manganese, Copper, Magnesium, Potassium
- the chemicals have to be heated because they aren't at their hot point which is what makes their colors.
