Why will insulators affect how long a test tube of hot water stays hot? Background Information I know that there are many different ways of insulating this test tube‚ shiny foil can be used because it’s a poor emitter of radiation and it will reflect escaping heat by reflecting‚ because this method is used in flasks to keep hot drinks warm. Though it is a good conductor so will lose heat through to surfaces its touching but it shouldn’t matter because it will be touching air and glass which both

comprehension or as I like to call it creativity. Funny Enough‚ I use the ocean‚ something so serene and effervescent to describe my annual quarter life crisis. Unconciously however‚ that must be no mistake‚ seeing that Water will be the theme of the experiment I will be working with. I’m still a little skeptical as to how I chose Water . There was no real inspiration‚ or interest on such force but rather an intuition that drove me to further explore this element. Perhaps an unconscious inclination

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

Social psychologist‚ Stanley Milgram of Yale University conducted a controversial and influential experiments on study of the effect of punishment on learning. Nearly 1000 people participated in Milgram’s 20 experiments. The participants assigned to be a learner and a teacher. Milgram created an electric ’shock generator’; it ranged from 15-450 volts. The teachers were given a task to teach and then test the learner on a list of word pairs. For the first wrong answer‚ the teacher will flip the switch

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
