"Reaction Ready" was a Quicklab where students got to see the effects of calcium chloride, baking soda, and water. Basically, they investigated a chemical reaction.
 As the chemicals react, heat and a gas are produced.
|
 Courtney laughs and backs off as Macy feels the heat.
|
 Abi & Jackie try to close the bag as quickly as possible.
|
 Since their bags didn't pop, David, Justin, Rick, & Ryan pick them up & begin investigating them. Curious little scientists, aren't they??
|
|
This bag pops, but it's not what people expected.
|
 Abi & Jackie are proud of their little bag of gas.
|
This bag pops with a little more excitement!
|
 Erika and Carina wait anxiously for the big POP!! at the end.
|
 Jackie and Abi were so proud of their little bag, they just had to have another picture with it!
|
Ryan's bag didn't pop, so he
helped it along.
|
 Ryan & Tim were so excited for the bag to pop, they had to get a close-up view! |
 Jackie cheers on her bag to pop.

In "Speed Control", the students tested two factors that affect the rate of a chemical reaction: Surface Are and Concentration.
 Joe & Nick work together to measure the correct volume of HCl. |
 Grace keeps a close eye on the cylinder as Stephanie holds the funnel steady so Katie can pour the HCl accurately. |
 Rick's got this all under control himself! |

In "Cata-what? Catalyst!", the students discovered the effects of a catalyst. In this lab, they used an enzyme in beef liver to break down hydrogen peroxide. They also used this lab to investigate how surface area affects a reaction. They used one "whole" piece of liver, and ground up the other piece.
 Courtney & Haileigh gather 'round as Jessica displays the chunk of liver.
|
 Nick grinds up his liver while in the back, Roy plays with hot water.
|
 Al watches the reaction foam up.
|
 With two nice chunks of liver, Zach pauses, not knowing which one to grind to a pulp.
|
 Amber & Janine observe the reaction in awe before writing down their observations.
|
 Brad watches as Cole stuffs the liver into the test tube.
|
 Becca tries peeling more ground liver out of the mortar as Mary tries stuffing it down the tube.
|
 Cole gives this reaction a 'thumb - up'.
|
 Jackie watches & waits as Abi grinds up their liver.
|
 Jessica displays the used chunk of liver as she, Courtney, & Hailiegh observe the reaction of the ground-up liver.
|
 Ashley tries to get a good view as Taylor shoves the liver down the tube.
|
 Jackie & Abi watch in amazement as the catalyst goes to work.
|
 Michelle gets a good angle as Rick adds the liver.
|
 Stephanie watches as the reaction occurs while Zach is still shoving the liver in! |

The students investigate compounds that exhibit both ionic and covalent properties in "Fried Peanuts".
 Zack stuff peanuts into his beaker, but seems more interested in Al's part of the lab.
|
 Al stuffs even more in!
|
 Cheyenne & Becca are totally amazed by the polystyrene peanuts & acetone!
|
 Brittni mysteriously removes her glove as she & Jordan shove polystyrene peanuts into the acetone.
|
 Courtney & Amber keep adding polystyrene peanuts to the acetone, while Macy works diligently on the cornstarch peanuts.
|
 Aly & Stephanie watch as Grace drops the polystyrene peanuts into the acetone.
|
Here's a short video of Aly, Grace, & Stephanie.
|
 Keith keeps packing the cornstarch peanuts in water as he & James check out the other beaker.
|
 Rick watches intently as Ryan drops polystyrene peanuts in.
|
 Marina's having a great time adding the cornstarch peanuts, but Sasha doesn't seem to think that one's all that exciting.
|
 Troy gets a side view as Andy adds more peanuts.
|
 Haileigh's distracted by the static electricity as Jessica keeps adding peanuts.
|
 Tim & Joe alternate adding the polystyrene peanuts - and the acetone is keeping up!!
|
 Rick's pretty cautious, but even he can't keep his hands off this one!! |

In "Copper Plated Keys", the students used their knowledge of acids and ionic compounds to chemically combine copper ions onto metal keys.
 Tim records his observations.
|
 Zach & Justin do a little posing as their plating process begins. |
 Up close & personal with the copper plating process.
