Motion: Introduction

Motion: Introduction
Motion is one of the key topics in physics. Everything in the universe moves. It might only be a small amount of movement and very very slow, but movement does happen. Don't forget that even if you appear to be standing still, the Earth is moving around the Sun, and the Sun is moving around our galaxy. The movement never stops. Motion is one part of what physicists call mechanics. Acceleration is a twist on the idea of velocity. There are two main ideas when you study mechanics. There are also more complex movements when an object's direction is changing. In order to really understand motion, you have to think about forces, acceleration, energy, work, and mass. Or search the sites for a specific topic.

Let's Build A Simple Machine! Whether you do it for a school project or just for amusement on a rainy afternoon, building a simple machine is a great activity to work on with your child. Not only is building something an excellent way to spend time together, but doing so is also a wonderful opportunity for a straightforward engineering lesson. You can use the time to teach your child to recognize and understand the six types of simple machines: levers, wheels and axles, pulleys, inclined planes, wedges, and screws. A lever is a simple object, like a board or a beam, that rotates around a fulcrum. Intriguingly, the ancient Greek scientist Archimedes may have been the first to describe a lever in writing. Archimedes also wrote about the concepts behind the pulley and the screw.

Galileo Drops the Ball - Virtual Experiment In around 1590 Galileo Galilei (1564-1642) climbed up the Leaning Tower of Pisa and dropped some balls to the ground. Two balls of different masses, but of similar shape and density that were released together hit the ground at the same time. Until then it was commonly believed that heavy things fall faster than light things. Many people still believe this, and casual observation of everyday phenomena often does tend to confirm this view. Average vs. Instantaneous Speed During a typical trip to school, your car will undergo a series of changes in its speed. If you were to inspect the speedometer readings at regular intervals, you would notice that it changes often. The speedometer of a car reveals information about the instantaneous speed of your car. It shows your speed at a particular instant in time. The instantaneous speed of an object is not to be confused with the average speed. Average speed is a measure of the distance traveled in a given period of time; it is sometimes referred to as the distance per time ratio.

fun facts for kids about force and motion Force and Motion Motion makes all the things go ‘round’. When we think of motion, we often think of cars, bicycles, kids running, basketball bouncing and airplanes flying. But motion is so much more. It is important to our lives and impacts so many things that we do. Motion can be defined as the changing of location or position but it requires a force to cause that change. Simple Machine Activities Simple Machines Ideas and Resources Rather than a traditional lesson plan, this page is a collection of ideas and resources to bring the topic of simple machines alive for our students. If you have additional ideas or suggestions, please send them along.

Acceleration - Physics for Kids! Acceleration is a way to measure how fast something is speeding up. Suppose you are riding your bike. You start out going very slowly, hardly pedaling at all. Matter: Chemical vs. Physical Changes It is important to understand the difference between chemical and physical changes. Some changes are obvious, but there are some basic ideas you should know. Physical changes are usually about states and physical states of states.

Investigating Light and Color, lesson plan for grades 3,4,5 Grades: 3, 4, 5 Related Subjects: Science, Visual & Performing Arts Medium: Sculpture Class time required: 1 X 50 minute session Author: Museum of Photographic Arts Summary Students investigate the properties of light. They begin with an exploration of the visible light spectrum and follow up with an investigation into the primary colors of light. Materials Elementary Physical Science - Light Energy By completing computer and hands-on activities, students experiment with the concepts of transparent and opaque objects, shadow and reflection. As they record what they’ve learned, students build math and science skills by measuring length and making a graph to log results. Take the online material further by making use of the professional development available in the form of printable teacher guides.

Animal Life Cycles (FREE Learning Material) We are still continuing our vertebrate study and at this point we explored the life cycle of each group. The aim of this study is to compare the life cycle of each group, to differentiate their development and identify their similarities as well. Prior to this, I introduced the Animal Kingdom and the Vertebrate group. To start off, we have The Life Cycle of a Frog for amphibians.

When Things Start Heating Up © 2012 Purpose To understand how and why heat is produced from things that give off light, from machines, or when one thing is rubbed against another. Context This lesson is intended to give students a general idea of how heat is produced from human-based activities and mechanical and electrical machines. Top 10 Most Dangerous Plants in the World 1. Most likely to eat a rat Giant Pitcher Plant: Nepenthes attenboroughii Discovered more than 5000 feet above sea level on Mount Victoria in the Philippines, the giant, carnivorous pitcher plant secretes a nectar-like substance to lure unsuspecting prey into a pool of enzymes and acid.
