    • Miss: Hadeer Ibrahem Ali
    • What is Science ?
    • Characters of good teacher Knowledge "Being expert in your field". Interest. Respect. "Good Teachers have a deep seated concern & respect for students in class room. Creative.
    • If a single word had to be chosen to describe the goals of science education during the past 30 years it would have to be Inquiry. "Deboer 1991" Inquiry based learning A student centered active learning focusing on questioning, critical thinking & problem solving, it is associated with idea "Involve Me & I will understand".
    • Scientific problems. Focus on (How we know what we know) Evidence based. Indirect transfer of knowledge. Teacher`s role (facilitating).
    • What is a scientist? Are naturally curious and make a life out of asking lots of questions What does a scientist look like? What does a scientist do? What kinds of tools does a scientist use? what kind of scientist you would like to be?
    • What is Scientist ? "A scientist is a person who asks questions and tries different ways to answer them”.  How do students perceptions of science & scientists influence their attitude toward learning science? Every Young child is a small Scientist Aristo: "talk to see you"
    •  Scientists need to keep the observations and research they do organized.  The method they use to do this is called the scientific method.  The scientific method is a process of steps that helps scientists find answers to problems or questions.  The first step in the scientific method is called  the hypotheses.  The hypotheses is the scientists best guess at what will occur or happen in the experiment or thing being observed.  In order to test the hypotheses a scientist will repeat the experiment several times to see if the results are the same or different..
    • If the experiment is successful the hypotheses will be predictable and repeat over and over. The scientist will attempt to explain why this happens by gathering data, observing, and looking for evidence to support the hypotheses. If they find evidence to support the hypotheses, it may lead to the discovery of a new theory or law of science.
    • The scientific method is a process for experimentation that is used to explore observations and answer questions. Scientists use the scientific method to search for cause and effect relationships in nature.
    • Do Background Research Rather than starting from scratch in putting together a plan for answering your question, you want to be a savvy scientist using library and Internet research to help you find the best way to do things and insure that you don't repeat mistakes from the past.
    • Construct a Hypothesis A hypothesis is an educated guess about how things work: You must state your hypothesis in a way that you can easily measure, and of course, your hypothesis should be constructed in a way to help you answer your original question.
    • Test Your Hypothesis by Doing an Experiment Your experiment tests whether your hypothesis is true or false. It is important for your experiment to be a fair test. You conduct a fair test by making sure that you change only one factor at a time while keeping all other conditions the same You should also repeat your experiments several times to make sure that the first results weren't just an accident.
    • Communicate Your Results To complete your science fair project you will communicate your results to others in a final report and/or a display board. Professional scientists do almost exactly the same thing by publishing their final report in a scientific journal or by presenting their results on a poster at a scientific meeting.
    • Analyze Your Data and Draw a Conclusion Once your experiment is complete, you collect your measurements and analyze them to see if your hypothesis is true or false. Scientists often find that their hypothesis was false, and in such cases they will construct a new hypothesis starting the entire process of the scientific method over again. Even if they find that their hypothesis was true, they may want to test it again in a new way.
    • Steps 1. Be organized! Once you want to carry out an experiment, there are plenty of things to set up before you start. First Step A place to work If you want to carry out experiments successfully, you’d better set your own laboratory. You’ll need a large space to work, the most important thing you’ll need, is a large table or a working surface. And try to set a cupboard where you’ll keep materials and equipment required for your experiments, to keep them tidy and safe. To set up your work area remember not to get in the way of making a mess. You must protect your work surface with a large newspaper.
    • And here’s how to organize your work area: Work area storage area Writing area
    • 2. keeping a record of your work Science is like a puzzle. Every experiment and every thing you read is like a small piece of knowledge. You’ll need to keep a record of your work after any experiment, so that you remember what you have learned and you create your own puzzle. You can keep your own file, where you make notes about your experiments and any other scientific data you have learned. And you may need these records later, so make sure they are clear.
    • 3. Choosing your materials. At the beginning of each activity you want to do, you must decide the materials you need. It’s better to collect everything together on your work surface before you begin. If you have somewhere to store all your materials, you could start a collection of materials. That way you won’t have to spend much time searching around for them when you need them.
    • 4. Working safely Always remember that if you work carelessly, you could hurt yourself and other people. Safety for yourself If you’re using a sharp or heavy equipment, or using anything hot, remember to be careful with your fingers and you hands, and be careful not to spill any hot substances on your body. Never use the main electricity supplies. Always use a battery with the correct voltage you need. Be extra careful not to get any powders or liquids in your eyes. If something does accidentally squirt or blow into your eyes, rinse them immediately with lots of cold water and tell a doctor what has happened.
    • Teachers, could you use a little help? From finding high-quality, standards-based lessons and classroom activities, to staying on top of the issues, to finding professional development opportunities, educators are always on the lookout for useful opportunities to improve teaching and learning. It's important for teachers to stay current on research and continuing education and to be aware of new and valuable resources for the classroom. Educational resources abound both on and off the Internet, from government agencies to nonprofit organizations. So how can you stay on top of important news without having to search everywhere? Look to sites that speak to you directly as teachers and that are sponsored by credible and authoritative organizations. Interested in more? Check out these additional resources!
