School Science Projects based on Experiments

  1. 1. School Science Projectsbased on Experiments wdpd¾h ysrdka wurfialr jk yd mdßißl úoHd wOHhkdxYh" wOHhkdxYh wOHhkd Yh" YS% chj¾Okmqr úYaj úoHd,h
  2. 2. Everyone has a question. What’s yours? yours?Science Projects
  3. 3. I live in Mainland China.. “The exam-based education system has crushed nearly all of my spare time. And how can I do the experiment without any equipment? All schools love the examination so no one will let a simple student to use the equipment and research. And I must use a proxy to visit websites like YouTube, Twitter.So I think the people who have submitted Google Science Fair is lucky.”Science Projects
  4. 4. Types of Projects from Teachers’ Teachers’ Guide of NIE  Survey  Community Development y p  Solving a problem  Modernization of a product  Construction of product models  New discoveriesScience Projects
  5. 5. Aim of this Presentation Guide you to do Hypothesis based researchScience Projects
  6. 6. Two forms of scientific method Experimental projects employs numerical E i t l j t l i l data and graphs, (change one parameter and collect data) Descriptive projects gathers information through visual observation and interviewing interviewing. (assessing biodiversity etc.) Experimental Projects are discussed here.Science Projects
  7. 7. Steps in Science Fair Projects  Select a Topic  Gather Information  Make a Hypothesis.  Design, Conduct, collect data from an Experiment.  Reach a Conclusion (based on ) data)Science Projects
  8. 8. 1 Th R The Research Topic hT i  Your research question i what you h Y h ti is h t hope t to figure out.  Select a topic familiar to you or get advice from a scientist.  Eg- How growth rate differ in open grown trees and in plantation grown trees?  Comparison of growth rates in open grown tress and in plantation grown trees.Science Projects
  9. 9. 1 Th R The Research Topic hT i  Environmental Science E i t lS i  Zoology  Botany  Agriculture  Computer Science Research fields  Chemistry For Sri Lanka Science  Earth Science/Space Science and Engineering Fair  Mathematics  PhysicsScience Projects
  10. 10. 2. Gather I f 2 G th Information ti  Learn everything about th t i (R i L thi b t the topic. (Review Literature)  From book, magazines, the internet, talk to p p people and experts p  Initial ObservationsScience Projects
  11. 11. 3. Make a Hypothesis yp  The h Th hypothesis i what you expect t th i is h t t to happen in your experiment. (possible answer to the problem)  For th F the research question about t h ti b t tree growth (above), the hypothesis might be, "Open grown trees grow faster compared Open with forest grown trees"Science Projects
  12. 12. 4. Experiment – Design p g  You can start with an experiment with one variable.  Consider your "sample size.".  Location  Experimental Material (What species?)Science Projects
  13. 13. 4. Experiment – Design p g 3. The P 3 Th Procedured  Experiment – Measure tree diameter at 1.3m above ground (diameter breast height - DBH) in plantation trees and in open grown trees  One variable = DBH with 2 levels (OG and PG) ( )  Sample size = 50 trees from each level  Should find a location that contains both types of y trees  Species = teak  Trees should be similar agedScience Projects
  14. 14. 4.4 Experiment – Design We can add another Open Plantation variable = tree grown grown (PG) height g (OG) We can have 2 way OG PG experimental design Spp 1 spp2
  15. 15. 4. Experiment – Record data (Results)  Results are the data, or information, that you collected. Your data should be in numbers. Dont just write that the plants "look bigger"; write down exactly how much they grew.  You can enter data in a table.Science Projects
  16. 16. 4. Experiment – dataPresent your results and give explanations explanations. DBH Mean DBH (cm) Open grown X x x x x x x O 15.6 15 6 trees xxxxxxx x Plantation Yyyyyyy 10.2 grown trees y y y y y y ..
  17. 17. 5. Reach a Conclusion  The Th conclusion i what you l l i is h t learned f d from d i doing the experiment.  In just a few sentences your conclusion explains sentences, what happened in your experiment and whether it supported your hypothesis. Above example = Open grown tress grow faster compared with plantation grown treesScience Projects
  18. 18. 5. Reach a Conclusion – Discuss the results  Discuss your results, whether you accept the hypothesis or not. What are the reasons for doing so.  What if your results do not support your hypothesis? That is perfectly fine. Youre not out to "prove" your hypothesis but to test it. Think along the lines of "heres what I here s thought was going to happen, and heres what actually happened." Then go on to explain why you think things happened the way they did.  Compare results with similar experiments carried out by others.Science Projects
  19. 19. What makes a good science p j g project?  Look for original ideas.  Have a well-defined objective j  Understanding of the basic science b hi d th U d t di f th b i i behind the project topic.Science Projects
  20. 20. What makes a good science p j g project?  Support your conclusion with with data and S t l i ith ith d t d results  Put enough time and energy into your project.  Clearly present your work. Judges look for well- written abstracts with easy-to-follow visual aids y and clear and concise answers.Science Projects
  21. 21. Present your findings  Report to School  Young Environment Symposium  Sri Lanka Science and Engineering Fair  Intel International Science and Engineering Fair (Intel ISEF), USA  Google Science Fair ProjectsScience Projects
