float. Any object with density more than that will sink. Carbon dioxide‚ or CO2‚ also played a big role in this experiment. Many soft drinks contain CO2. Studies show that Sierra Mist had the most carbonation out of most soft drinks. There was a lot of carbon dioxide in the soda. That was the reason the raisins would float up and down. There were many purposes to this experiment. One purpose was to teach us about density when we saw how the raisins floated to

Liza Handler Experiment Background: Squid is a keystone species‚ negative effects on them can have major consequences down the line. Nearly all of the animals in the oceans ecosystems either eat squid‚ or are eaten by squid. Squids not only have a vital role in our Oceans ecological community‚ but they also are important economically. Squid is a main source of food for the tuna and hake‚ two major commercially important fish. In 2011‚ fisherman harvested a total of $100 million worth of squid

The details of this case may offer further insight into the admissibility of experimenting on children as long as there is parental consent and the consenting parents are fully aware of all details of the experiment.

| Analysis: The number of heart beats increase‚ as the caffeine concentration increases‚ as shown in the results. Conclusion: The hypothesis was correct as the heart beat did increase as the caffeine concentration increased. However‚ this experiment could have been more fair due to the following: * All the daphnia used

Experiment 1: TLC Analysis of Analgesic Drugs 1/23/2011 Purpose: The goal of this experiment is to test our knowledge and understanding of TLC analysis by having us do a TLC analysis of analgesics to figure out their main chemical components. Calculations: 1.) Rf = Distance spot traveled/ distance solvent traveled Results: Table 1: TLC Analysis Analgesic Drugs | Rf Value | Acetaminophen | 0.323 | Aspirin | 0.597 | Caffeine | 0.081 | Unknown 154 (Plate 1) | 0.081‚ 0.306‚ 0.597

As stated above‚ humans have a need to be accepted by others and for this to happen‚ each individual within the group must share the same belief as the group.An experiment by Donna Webster and Arie Kruglanski showed that dissenters who voiced their opinion were rejected by the entire group and this explains that we tend to conform to behaviors around us for the sake of not being rejected(Kruglanski & Webster‚ 1991)

The purpose of this lab was to determine if a there is a change in mass when a gas is produced and determine if gas has mass. To conduct this experiment‚ the group must be careful not to let the Alka-Seltzer tablet get wet before the bottle is closed by wiping the lip of the bottle and the cap so it remains dry‚ or risk gas escaping into the air and not being captured by the bottle. Also‚ the group must be sure to close the bottle tightly with the cap‚ because gas may escape this way as well. During
