Visit the Human Origin Hall of the Natural History Museum and the Q?rius room to learn about the human origin and determine the following: Where in the globe the oldest lineages of hominids were found? How recent findings of fossil hominids changed the idea of origin of human lineages? What characters scientists used to find out whether a giving fossil hominid represents an older or more recent lineage? Provide two hypotheses of selection pressures that could drive shape changes in t...

Abstract: This lab will test the effect of Red Bull on heart rate. Red Bull is an energy drink containing caffeine, which has been used/marketed to give the US consumer more energy. With this energy, it is hypothesized that there will be an increase in heart rate. An increase in heart rate that could caused by many factors, which one happens to be caffeine, is an ingredient in Red Bull. Therefore, it can be assumed that there will be an increase in heart rate. As a result, to test the hypothes...

Abstract: This experiment tests the competition plants face when they grow in high concentrations of plants. It has been hypotheses that the more competition the more the plants will struggle to grow. According to research it has been found that there with more competition plants will struggle to grow, specifically with the concentration of seeds. To test the hypothesis this lab will use pots with various amounts of seeds and analyse their growth to reach a conclusion. This lab was inconclusi...
