What are the 3 levels in science?
the three levels are as known to me:DRAGONSS, ARE: PHYISCAL,CHEMITCAL,AND SPACE, REASON, ON EARTH PHYICAL SCIENCE IS ABOUT THE BEHEAVIOR OF PHYISICS. CHEMITCAL DEALS WITH THE BEHEAVIOR OF CHEMITCAL ELEMENTS AND COMPOUNDS. SPACE SCIENCE DEALS MUCH WITH THE BEHEAVIOR UNIVERSE AS MUCH AS WE CAN UNDSTAND IT. THE LAWS OF LIFE ON EARTH ENTENDS INDEFINITLY IN THE THE UNIVERSE. HOWEVER THE LAWS OF PHYISCS DO NOT. DROPING A BALL ON EARTH WILL HAVE DIFFER EFFECTS IF DROPED IN SPACE OR ON ANOTHER PLANET. HOWVER THE LAWS OF LIFE ON EARTH ARE THE SAME UNIVERSALLY. TO STAVE OFF DEATH ON EARTH LIFE MUST IN TAKE WATER,FOOD,OXYIGEN AND SLEEP. THIS ALSO MUST OCCURE WHERE EVER WE GO IN THE UNIVERSE
What is the difference between core science and additional science?
The specific difference depends upon the exam board. Before the last set of educational reforms double balanced science was a 2 year course comprising of coursework, 6 multiple choice exams (usually sat in year 10) and 3 long answer exams (usually sat in year 11). The end results were 2 identical grades representing the whole course. Significant education reform changed this system and created core science. Core is primarily made up of a back bone of the old year 10 course but with significant deletions and some diluted content from the old year 11 course. Core science is the basic legal requirement for all students to study. The content within core is also found in Applied science and the BTEC course. How the exams and coursework elements are assessed for Core science radically differ for each exam board and even within exam boards (as different versions of the Core course are offered). Additional science was formed from the backbone of the old year 11 course but lost some elements to core and gained some both from the old year 10 course and the old A-Level courses although in significantly diluted forms again. Both courses are discrete qualifications with their own grades. Core is still primarily studied in year 10 and Additional in year 11 but this is changing and many schools have now opted to start Core in year 9 and Additional in year 10. This allows for more resit opportunities but also makes it possible to have significantly more pupils ditching the Core and Additional structure and, instead, studying Triple science where discrete qualifications are gained in Biology, Chemistry and Physics. This may sound like a significant change but in reality it is just the same courses but together with a few more modules added on the end. The advantages of doing Triple science over three years are: resit opportunities, it doesn't take an option block away and pupils have more time to develop.

Physical Science Applications Assignment Brief 4Rokeby SchoolScience DepartmentCourse Title: BTEC First Certificate in Applied ScienceAssignment Title: Generating and using electricity.Tutor Name:Learner Name:Start date:Deadline:Unit : Physical Science ApplicationsScenarioYou are a production engineer working for British Energy which is an electricity provider. The company is looking into ways to produce, use and transmit electricity more efficiently. You have been asked to research how the company currently generates electricity, including an analysis of the efficiency of transmitting and converting electricity for consumers on the National Grid. You have to write up your research in a report.Assessment EvidenceThe grading criteria that this activity relates to:P4 describe two ways in which electricity may be producedM4 explain two applications of electricityD4 analyse the problem of energy losses when transmitting electricity and when converting it into other forms for consumer applicationsCompletedSummary assessor's feedback Areas for improvement:Criteria AchievedP4M4D4.Internal Verifier's CommentsLearner's SignatureI, ______________________, confirm that the work submitted is entirely my ownSignedGenerating and Using ElectricityPhysics Applications Assignment 4Task 1-Describe how electricity is generated in a fossil-fuel power station. Include a labelled diagram and a written description of the process. Include a diagram of what happens inside the generator and flow charts.-Describe the main similarities and differences between a fossil-fuel power station and generation of electricity using renewable energy resource such as a wind mill farm.- Describe how a battery produces electricity. Include an equation for a chemical reaction which occurs inside a battery and explain the difference between rechargeable and non-rechargeable batteries.P4Task 3Explain how electricity is used in motors and loudspeakers. For each one, include:an energy transfer diagrama labelled diagram of the componenta written explanation of how the component worksM4Task 4When electricity is produced at a power station, it then has to be transmitted through overhead power cables or underground cables to the local substation and then to the consumer.Discuss how energy is lost in this process and how this energy loss can be minimised.Many consumer applications of electricity require a transducer or a transformer eg, mobile phones, laptop computers, loud speakers etc.Explain why a transformer is needed.Discuss how energy is lost in this process and how this energy loss can be minimised.D4
