This is our charity fair poster About the Project Every year, adventure hosts a charity fair, in which the students select a charity and then sell products that relate to the cause and the charity. During this project, there are many assignments that are required for each class. For example, in history, we did research on our charity and in electives, we created our how-to. Each group presents and the top group from each class then continues to finals, where they present to Student Council, and the best presentation is chosen. Summary During this charity fair project, I learned a lot about our charity and what they are passionate about. The Children’s Defense Fund makes sure every child can reach their full potential. They guide, and support kids that need special treatment. Their goal is to create a loving atmosphere where children can learn and grow. One of the major issues they are trying to address is kids who have experienced school shootings. They also want to focus on...

Distance-time graphs  by  BBC Summary Speed and Velocity  may sound like very similar quantities, however, they have a very different meaning. Velocity has a direction. An example of velocity may be 40 m/hr north. This means that it is a vector quantity. However, speed only has a magnitude. an example of speed would be 40 m/hr. This means that it is a scalar quantity. The average speed is a measure of distance traveled in a given period of time. To measure the average speed, we can use a distance per time ratio. For example, if we traveled 80 miles in 2 hours, we can create the following ratio: 80 miles / 2 hours, or 40 m/hr. To represent the average speed, we can use a distance-time graph. On the horizontal, or x-axis, we write the time taken. In the example above, we would put 2 hours on the x-axis. On the vertical, or y-axis, we write the distance traveled. In the example, that would be 80 miles. Various lines on the graph mean different average spee...

File:Distancedisplacement  by  Stannered Summary: Distance and displacement are quantities that define two different lengths. Distance refers to how much ground an object has covered. This means that distance is a scalar quantity or a measure of magnitude. However, displacement refers to the shortest possible length between the start and end points, or the change in placement of an object. This means that the displacement is always measured in a straight line.  Distance and Displacement by BYJU'S For example, in the image above, we can see that the distance is the overall route the object took, however, the displacement is a straight line measuring the length between the start and end position. In the image at left, we see that the object traveled from the tree (point a) to the house (point b) to another tree (point c). To figure out the distance, we add the two lengths (3m + 4m = 7m). This means that the distance is 7m. However, to find the displacement, ...

Summary: Choices that we make in our everyday lives affect the world and contribute to greenhouse gas emissions. It is very simple to forget about the effect that we have on the environment. There are so many ways that we are polluting the environment. For example, the products that we use can have a lot of emissions from transportation. It is important to think about how products manufactured far away can have a big effect on the environment.  A Carbon Footprint is a way to calculate the greenhouse gas emissions that are created by a person, place or thing. Most greenhouse gas emissions come from transportation and are carbon dioxide emissions that can harm the environment. To reduce the transportation environmental impact, it is important to buy materials that are made and sold locally. This would ensure that the materials are not traveling a very far distance, which would mean it would be better for the environment, and there would be less carbon dioxid...
