English: Spent most lessons writing vocabulary words down, I had one test before the reset, and I will likely have another. As for the reading/writing, they usually have me read a story and analyze it, sometimes answering questions. Biology: Hydrogen Bonding in Water Intro to properties of water capillary action and meniscus surface tension cohesion of water Water as a solvent Specific Heat, Heat of Vaporization, and Density of Water Unique Properties of Water Water is polar Water is an excellent solvent Water has high heat capacity Water has high heat of vaporization Water has cohesive and adhesive properties Water is less dense as a solid than as a liquid Carbon as building block of life Functional group Ionic and Covalent Bonds World History It’s difficult to decipher most of our world’s pre-history due to embellishment, life before written records, bias, language barriers, etc. Without written records we learned to learn about history with fossils, artifacts, etc. Homo sapiens are a group of hominids who survived past most of the hominid species. Different theories explain that the homo sapiens began walking upright as their homes in trees began disappearing and the savannahs began expanding. As they began migrating, a land bridge during the Pleistocene Ice Age opened up that connected Asia and North America, which is what is believed to have gotten homo sapiens to North America. They likely left their homes in Africa due to lack of food and resources. About 50,000 years ago, when humans could start communicating, they could voice these concerns to each other. After they migrated, they had to adapt to a colder climate. They began hunting more animals for food, clothes, and shelter, which likely led to the extinction of many animals. Humans had to rely on the earth’s natural resources for their semi-permanent homes. The migration led humans to the Paleolithic era, which was heavy on hunting and foraging. Small bands of hunter-gatherers worked together before agriculture. Humans had yet to learn about domestication and farming, so they thought hunting-foraging was the best system. As they began migrating environments, they began making tools and weapons. Geometry Reviewing transformations of shapes (translation, reflection, rotation, dilation, etc.) up until now so far.
