Great white sharks

             Great whites are the largest predatory fish on Earth. They grow up to an average of 15 feet in length, and they are20 feet or 6 meters long and weighing up to 5,000 pounds or 2,268 kilograms. They have slate-gray upper bodies to blend in with the rocky coastal sea floor, but get their name from their universally white bellies. They are fast for how big they are but they can up to 15 miles per hour. speeds of up to 15 miles per hour. They are so powerful they can even leave they water completly. They are Highly adapted animals their mouths are lined with up to 300 teeth, triangular teeth arranged in several rows, and they have an exceptional sense of smell to detect prey. They even have organs that can sense the tiny electromagnetic fields generated by animals. Their main prey items are sea lions, seals, small toothed whales, sea turtles, and carrion. They live in the cool coastal waters of Africa mostly. However scientists agree that their number are decreasing becuase they are being over fished and get caught in gill nets. The reason I choose to study the great white shark this blog so I can understand more about the Great whites and not just there man eaters.

Solids, liquids, gases



          Solids are a very tigh patterned particles. They are in a pattern and stay in a pattern. If a solid gets to hot it will melt and turn into a liquid. Liquids are always together but hit each other. They always are close and flows easily. If the liquid gets to hot it evaporates and turns into a gas. Gases form the shape volume of its container. They always bounce off each other. The can repeat the process from the gas and all you do is make it colder and colder.They have some similarities like they are both made up of protons and neutrons and classify as matter.

Yellow fever


            Today I studied the dease called yellow fever and was very bad in the 1700s and 1800s to the Europeans. Today our medicine level is so high that we can just got to the doctor and pick up the vaccination. Back then they couldn't do that and a lot of the population died. Today the middle of South America and africa are very high in yellow fever cases. The reason is the yellow fever is caused by maquestios and those places are full of swamps. Maquestios live in swamps.
