neither man would expect the effect these elements could have on modern science‚ namely rockets. But creating a rocket is just combining these two gases in a closed environment‚ and one spark. This lab exemplifies just that what happens when the gases H2 and O2 are chemically combined with a spark. In this lab‚ the objective was to see how far a pipette filled H2 and O2 could travel. One half a centimeter of H2O was added to keep the gases inside‚ and make sure that only these H2 and O2 where included

African Diaspora and the World After reading the short story “Diaspora” by Joanne Hyppolite‚ I got a vivid understanding of how diaspora can have an effect on one’s identity. Over the past month we have studied many theories and concepts concerning race‚ gender‚ and politics. There are three theories that capture the essence of Joanne Hyppolite’s worldview as a Haitian growing up in America: intersectionality‚ identity‚ and diaspora. Individuals oftentimes experience the theory of Intersectionality

known as S. typhimurium‚ is a Gram-negative‚ rod-shaped‚ flagellated‚ facultative anaerobe microorganism. S. typhimurium can be found in animal feces and raw contaminated foods such as poultry‚ beefs‚ sea foods‚ tainted fruits and vegetables (3‚ 5). Some of the vectors of S .typhimurium are birds‚ reptiles‚ and aquatic vertebrates (5). After the consumption of the bacterium‚ S. typhimurium is found living and growing in the mammalian GI tract.

Density (Linearized plot) TA: Blue Rex rex Group Members: Billy and Mandy Tuesday; 1200-1350 Abstract: In this lab the density of hand-made clay balls were calculated to understand how scientists model physical effects and to understand logarithmic plots. The hand-made balls ranged from diameters of 2cm to 6cm and were measured with vernier calipers by each member of the group. A total of 6 independent measures of each diameter were taken to establish uncertainty. The clay balls were then
