Torque was discussed extensively. The experiment is divided into two parts. In the first experiment‚ the meter stick was weighed and the group was tasked to find the center of gravity of the uneven meter stick and supporting the meter stick other than its center of gravity‚ bring it into equilibrium using the weight of a single mass. In the second part of the experiment‚ the meter stick was supported on the 30 cm mark and weights were applied (200g at 10 cm mark‚ 100g at 20cm mark‚ 20g at 90 cm

Glow Stick Lab – Informal Hypothesis: I believe the glow sticks will become ultimately brighter in the warmer temperature beaker as heat cause molecules and particles to move faster and rapidly thus producing energy where as when the glow stick is the cold temperature beaker I believe it will dim in light as energy id being taken away as particles are moving much slower and are closer to each other. Materials: * Hot plate * Two beakers (200mL) * Two glow sticks * Water * Thermometer

The Incident of the Goalie Stick I had just finished my hockey game‚ one which we lost by far. I slowly skated my way off the ice‚ as everyone looked at the “losing team” in disappointment. I stepped my way over to the locker and to my surprise‚ a couple of kids had found a broken goalie stick‚ and the floor was a mess with splinters. It looked as if a volcano had erupted in the left side of the tiny locker room. These kids swung it back and forth‚ trying to break it‚ but had no luck in doing so

more than likely‚ the dog did indeed descend from the gray wolf. Although the oldest fossils of a domesticated dog are from a 14‚000-year-old dog grave‚ DNA evidence suggests dogs diverged from wolves much earlier than that (with estimates ranging from 15‚000 to more than 100‚000 years ago) [source: Wade]. Regardless‚ historians agree that humans domesticated dogs before any other animal -- making dog man’s oldest friend‚ if not his best. Scientists can only guess how dogs and humans first became
