Summary: Geology is the study of Earth, as well as Earth's structure and the forces that shape it. Abram's principal or James Hutton's principle is that geologic processes that operate today operated the same way in the past or in other places that have the same conditions.Hutton's principal, uniformitarianism, allows us to estimate what happened to rocks long before humans roamed the Earth and can help us predict what may happen to Earth in the future. There are three types of rocks, igneous rocks, sedimentary rocks and metamorphic rocks. Igneous rocks form when molten material from under the Earth's surface cools and hardens. Sedimentary Rock is made of sediments that have been deposited on top of each other and pressed together to form solid rock. Metamorphic rock is an existing rock that has been changed by heat, pressure or chemical reactions. Landforms are features on Earth's surface like mountains that are made when two plates meet. Fun fact, the dif...

Scenario: Students in Mrs. Garcia's class use a class chart of what different animals eat and group the animals in different ways based on their food sources. Students then discuss which animals would be affected if changes occurred to different food sources. Wrong Answer: Using Mathematics and Computational Thinking Correct Answer: Analyzing and Interpreting Data Why: The correct answer is Analyzing and Interpreting Data because the students are looking at a chart to and analyzing what each animal eats, as well as how things would change if certain food sources were different. This is the correct answer because they are studying the chart in different ways and trying to predict and analyze what will happen if changes were made. Scenario: A group of 7th graders creates and analyzes graphs of the data from an investigation about the relationship between a ball's mass and its speed down a ramp. Wrong Answer: Analyzing and Interpreting Data Correct Answ...

     My name is Sohini Pillay and I am an 8th grader at AdVenture, a STEM program. As any other student, I go to school and complete the work I am assigned. I walked into class posed with the question of, "Why I returned to AdVenture?" I had to think about this for a while before I realized that I had never stopped to think of it before. I have been a student at this school starting in 5th grade and it has been second nature to go to this school there ever since. Although there are many, many wonderful things about AdVenture there are some main aspects that keep most students from leaving, including me.      One of the reasons my parents and I decided for me to continue learning at AdVenture is because I am going into the 8th grade. I know you're probably thinking, "It's just the 8th grade," but most people don't understand that transferring to a new school for one year is pointless and more work than it has to be. If I moved schools I would have to g...

Science News for Students Summary: With the rates of young people using e-cigarettes climbing, people are beginning to discuss the downs of vaping. Some say that e-cigarettes may be the healthy alternative compared to a regular cigarette because they do not contain tobacco, but an e-cigarette can be just as harmful. E-cigarettes contains nicotine, found in regular cigarettes, which creates the habit of regular smoking. In addition to this, nicotine is harmful to developing brains which is why no young people should be using e-cigarettes. Along with nicotine, there are other harmful components that go into making an e-cigarette. The flavorings of e-cigarettes may sound kid friendly, but they release chemicals that can irritate your lungs. Citation: Rosen, Meghan, and Janet Raloff.

An acid that has a pH of 6 is weak while an acid that has a pH of 1 is strong. Bases have a pH ranging from 7.1 to 14. The lower the pH, the weaker the base.  A base that has a pH of 8 is weak while one that has a pH of 13 is strong. Neutral substances have a pH of 7. One example of a neutral substance is water. Acids have a sour taste, while bases have a slippery feel. Acids turn a litmus paper red and bases turn litmus paper blue. A litmus paper tests a pH of a substance. Fun fact, even though it is better to drink an acid rather than a base cough syrup is a base (it stabilizes the acids in your stomach). S&EP: Even though we didn't do anything big this week, like an experiment, my group and I carried out a mini investigation of our own. As we have been doing lately, we play the legends of le...

Image: Science & Biology Summary: A solution is a liquid that contains a solid that is so spread out that it is no longer visible to the naked eye. A base is high on the pH scale because creates a lot of hydroxide ions when mixed with water. Bases are extremely bitter and a common example of a base would be soap. On the other hand an acid creates a ton of hydrogen ions and is lower on the pH scale. The pH scale measures how acidic or basic a solution is, 14 being the most basic and 1 being the most acidic. Water is neutral meaning it is smack dab in the middle of the pH scale. If you have two beakers containing clear liquids, but one is an acidic and the other is a base how would you tell the difference. We would use a simple piece of litmus paper. Litmus dye is taken from lichen and put on paper. Adding acid to the mix would have red litmus that would be for testing bases and vise versa for testing acids. S&EP- Conducting Investigations: To start off the week we co...

Image: Twitter Summary: Atoms are the building blocks for everything in the world. Compounds are two or more atoms that combine to make something new. A chemical reaction is when atoms come together or break apart to form new things. The Law of Conservation and Mass states that atoms cannot be created or destroyed, only rearranged. Extra atoms after a chemical reaction become waste to be used in another reaction. Atom economy is the attempt to have as few atoms leftover from a reaction as possible. An experiment of burning sulfur proved that weight can transfer during a chemical reaction. During this experiment the burned sulfur weighed less than it did before, but the air around it weighed more.  S&EP-Conducting Investigations: You can tell that a chemical reaction occurred if gas was created, a change in temperature, and a change in color. There are times when a reaction occurs, but you cannot tell because the reaction is going at such a slow pace. This week i...
