Procedure
[Types of Variables] [Activity #1] [Activity #2] [Activity #3] [Steps to Success] [Move Beyond] You're doing great! You've chosen a topic and asked a question. You've done a little bit of research and made a best guess as to what the answer might be. Now it's time to design your experiment. The first step is to write the procedure. The procedure is a set of very specific instruction about how you are going to conduct your experiment. Sadly, no one could eat the sandwich on the left. Variables Details also help to control variables in your experiment. Independent Variable The independent variable is the one that YOU choose to help you answer your question. If there's more than one independent variable, the experiment becomes flawed because you can't be sure what caused the changes you observed. Activity #1: Start Thinking! Look at the image to the right. Take some time to think about how this student might write the procedure for this experiment: What are the controlled variables?
Understanding Science: An overview
To understand what science is, just look around you. What do you see? Perhaps your hand on the mouse, a computer screen, papers, ballpoint pens, the family cat, the sun shining through the window …. Science is, in one sense, our knowledge of all that — all the stuff that is in the universe, including the tiniest subatomic particles in a single atom of the metal in your computer’s circuits, the nuclear reactions that formed the immense ball of gas that is our sun, and the complex chemical interactions and electrical fluctuations within your own body that allow you to read and understand these words. Science helps to satisfy the natural curiosity with which we are all born: Why is the sky blue? Science is complex and multi-faceted, but the most important characteristics of science are straightforward: Science is a way of learning about what is in the natural world, how the natural world works, and how the natural world got to be the way it is. Where to begin?
How we edit science part 1: the scientific method
We take science seriously at The Conversation and we work hard to report it accurately. This series of five posts is adapted from an internal presentation on how to understand and edit science by our Australian Science & Technology Editor, Tim Dean. We thought you might also find it useful. Introduction If I told you that science was a truth-seeking endeavour that uses a single robust method to prove scientific facts about the world, steadily and inexorably driving towards objective truth, would you believe me? Many would. The public perception of science is often at odds with how science actually works. But science is actually far messier than this - and far more interesting. In order to report or edit science effectively - or to consume it as a reader - it’s important to understand what science is, how the scientific method (or methods) work, and also some of the common pitfalls in practising science and interpreting its results. What is science? Science is not a body of knowledge.

The scientific method is a process for experimentation that is used to explore observations and answer questions. Even though we show the scientific method as a series of steps, keep in mind that new information or thinking might cause a scientist to back up and repeat steps at any point during the process. Whether you are doing a science fair project, a classroom science activity, independent research, or any other hands-on science inquiry understanding the steps of the scientific method will help you focus your scientific question and work through your observations and data to answer the question as well as possible.

How to quickly spot dodgy science
I haven’t got time for science, or at least not all of it. I cannot read 9,000 astrophysics papers every year. No way. And I have little patience for bad science, which gets more media attention than it deserves. I, like most scientists, filter what I read using a few tricks for quickly rejecting bad science. Okay, this looks bad Good science is often meticulous and somewhat anxious. If you’re taking the time to do meticulous science, why not take the time to prepare a good manuscript? Recently, Ermanno Borra and Eric Trottier claimed to have detected “signals probably from extraterrestrial intelligence”. Was my caution justified? Furthermore, the surprising conclusions relied on a tiny subset of data, and there was no attempt to confirm the conclusions with additional observations. Of course, there are exceptions to good-looking good science. To be honest, I’m with Connare on the slides. Obviously “That’s obvious, why didn’t someone think of that before?” Well, perhaps someone did.
How to (seriously) read a scientific paper | Science | AAAS
Adam Ruben's tongue-in-cheek column about the common difficulties and frustrations of reading a scientific paper broadly resonated among Science Careers readers. Many of you have come to us asking for more (and more serious) advice on how to make sense of the scientific literature, so we've asked a dozen scientists at different career stages and in a broad range of fields to tell us how they do it. Although it is clear that reading scientific papers becomes easier with experience, the stumbling blocks are real, and it is up to each scientist to identify and apply the techniques that work best for them. The responses have been edited for clarity and brevity. How do you approach reading a paper? I start by reading the abstract. I first get a general idea by reading the abstract and conclusions. If you want to make it a productive exercise, you need to have a clear idea of which kind of information you need to get in the first place, and then focus on that aspect. All the time. Be patient.
Is this study legit? 5 questions to ask when reading news stories of medical research
Who doesn’t want to know if drinking that second or third cup of coffee a day will improve your memory, or if sleeping too much increases your risk of a heart attack? We’re invested in staying healthy and many of us are interested in reading about new research findings to help us make sense of our lifestyle choices. But not all research is equal, and not every research finding should be interpreted in the same way. So how can you tell? 1. Peer review is a process by which a study is checked by experts in the discipline to assess the study’s scientific validity. This process involves the researcher writing up their study methods and results, and sending this to a journal. If there are major flaws in a study, it’s either rejected for publication, or the researchers are made to address these flaws. Although the peer-review process isn’t perfect, it shows a study has been subjected to scrutiny. À lire aussi : Peer review has some problems – but the science community is working on it 2. 3. 4. 5.
