Science and Tangents

               Newton’s Amusement Land introduces the types of heat transfer including  conduction, convection, and radiation.       In this experiment I will be using conduction as the pot will be in direct contact with the flame and the water will be heated through touching the heated surface.       The heat will escape from my glass because the water it meets air around it and is attempting to reach equilibrium. By creating insulation, the heat can be contained longer due to the “small air spaces” (Tillery, Enger, & Ross, 2019, p.86).  The materials used in this experiment include four identical glasses, a tea kettle, four rubber bands, a thermometer, water, and the insulators tinfoil, parchment paper, snack bag, and a washcloth.       Animals in colder habitats are designed to retain heat by having a thick layer of blubber. I predict that the washcloth will minimize the heat transfer as it is a thicker material compared to the other items. I think the parchment paper will caus

   My daughters and I explored the question How do different surfaces affect the momentum of marbles?  During the experiment, we released the marble with a ramp we built from a marble coaster kit we already had. We tested how the marble would roll across chart paper, a blanket, a yoga mat, and a laminate floor.  Tillery, Enger, and Ross (2019) describe friction as an opposing force that works against the motion of an object. This exploration will directly investigate the impact friction has on the motion of an object. Our results included t he following averages.          laminate floor - 44 inches          chart paper - 32 inches          yoga mat - 5 inches               blanket - 5 ½ inches    I expected the chart paper to be the greatest distance as it was smooth and provided little in the way of obstacles. My laminate floor has cracks and water damage so I expected that would provide more resistance to the marble. The laminate likely had an impact on the paper due to the marble ch
