Science 10: Motion in our World

Unit Key Questions: What are the characteristics of the motion of objects that exhibit uniform motion or uniformly accelerated motion? How can we describe motion and the changes in motion of everyday objects? What are different methods of representing the motion of everyday objects and what are the advantages and disadvantages of these methods? What are some methods of determining the position, speed, and acceleration of everyday objects? Unit Key Concepts: The motion of any object can be described by its position, direction of motion, and speed. That motion can be measured and represented on a graph or by the use of mathematical equations. All motion is relative to whatever reference point the observer chooses. Since everything in the universe is moving, there is no fixed reference point in space from which to measure all movement.

Introduction to Motion “Almost everyone moves from place to place on a daily basis. We go to work, school, stores, or places for entertainment, and we do this in a variety of ways – walking, bicycling, or riding in cars, trucks, buses, trains, or planes. Motion, the subject of this unit, is part of our daily lives.” (Nelson, p.335)

Explore motion-related technologies (MW1) Key Questions (MW1): How and why do scientists and engineers conduct cost-benefit analyses of new technologies or inventions? (Activity – found online) How do scientists use testing to improve a technology? (paper-plane test) What are the major contributions of Canadians related to the science and technology of motion? (Q & A)

Science and technology  different but overlap and depend on one another Motto: Science is knowing Technology is doing Mission: The search for and theorizing about cause. The search for and theorizing about new processes. Focus: Focuses on understanding natural phenomena focuses on understanding the made environment Result Relevance: Making virtually value-free statements Activities always value-laden Evaluation Methods: Analysis, generalization and creation of theories Analysis and synthesis of design Goals achieved through: Corresponding Scientific Processes Key Technological Processes Development Methods: Discovery (controlled by experimentation) Design, invention, production Most observed quality: Drawing correct conclusions based on good theories and accurate data Taking good decisions based on incomplete data and approximate models Skills needed to excel: Experimental and logical skills needed Design, construction, testing, planning, quality assurance, problem solving, decision making, interpersonal and communication skills http://www.diffen.com/difference/Science_vs_Technology

Recognize the contribution of science and technology to progress civilizations Class discussion: What types of technology do we take for granted today that weren’t around when we were born? When our parents were kids? Grandparents? How has science and technology improved the healthcare we take for granted today? Any other ideas?

Canadians in Motion Jigsaw Key Question: What are the major contributions of Canadians related to the science and technology of motion? (Q & A) Canadians have contributed many innovations to the science of motion and technology of transport. Q & A sheet  Start research today, finish tomorrow in class and then share your information with other classmates. Word Document  chart of who has been assigned which topic.

Variables that stay the SAME in each trial Experimental Variables Paper Airplane Contest Key Question: How do scientists use testing to improve a technology? Group Size: 2 (3 if necessary) Throw Area: RecPlex Competition Set Up: Control Variables Variables that stay the SAME in each trial Experimental Variables What we are testing for Experimental – wing span, same materials, length, tape placement,

Contest Rules (Fill This In) Sources of Error  stimulus that accidently gets incorporated into an experiment affecting the results. This could be beneficial or limiting. As a group we need to decide on what happens if a plane hits the wall or ceiling Disqualification? Retry x2? Unlimited retry? Distance stops where plan hits wall/ceiling?

Research & Test Trials Each pair gets three pieces of paper Do internet research on different styles of planes Build your planes Test out your 3 designs  we will go to the RecPlex and you will be able to select your best plane for the competition After testing your designs measure the wingspan and length of your best plane that you will fly in the contest tomorrow!

Paper Air Plane Competition Each pair throws one at a time One partner is in the throwing area to mark where their plane landed Record your distance

Cost-Benefit Analysis Key Question: How and why do scientists and engineers conduct cost-benefit analyses of new technologies or inventions? As new technology emerges, people debate the benefits and the costs of each new innovation. What is the impact of the new technology on the environment? Who is responsible if something goes wrong? Who should pay for it? Many other questions arise. A cost-benefit analysis is a process used to determine the answers to these questions before the technology is released for public use.

There are 7 main perspectives to consider when researching the impact of a new technology Focus 1. Ethical Is the new technology right or wrong (based on beliefs and values)? 2. Legal Who is responsible for the effects of the product? How will affected people be compensated? 3. Ecological How will the product impact the environment? 4. Technological How will the product be manufactured? Can the performance be improved?

Perspective Focus 5. Political What is the role of the government? 6. Economic How much will it cost? Who pays for it? 7. Scientific What could be the outcome of the change? What problems may arise from it?

Current Innovations To Research High speed transportation Creating a new high way Uranium processing plants Open pit mining Fish Finders Radar Detectors

Cross-Benefit Analysis Assignment Choose a partner Together, choose a topic Choose 4 perspectives to base your debate around One partner researches the benefits and the other researches the costs (according to the perspectives discussed) Prepare a debate

Debates Groups will prepare a 2 minute debate to carry out in front of the class After each debate, the class will take a vote on if the product benefits or is detrimental to the environment/society.
