![]() Using all the results and the data collected, we can form a conclusion. So, we noticed something, asked why it happens, brainstormed reasons, tested our ideas, and got some results. (Yes – if the wind blows the plane behind you in the opposite direction, you may have a negative distance reading.)Īgain, record your results. To further test our hypothesis, try throwing the plane against the wind several times as well as throwing it in the direction the wind is blowing. Again, throw the plane several times and take an average of your time in the air and distance measurements. Since we’re testing the wind’s effect on our flight, it’d be best if there is at least a breeze when we’re testing. You could do this simply by writing each flight distance and time on a scrap of paper, or you could use a scientific journal or log book. You may want to do this several times and take an average distance and time. How can you test your hypothesis to prove or disprove what you think will happen? Think of different variables that may affect your results and try to include these in your testing.įor the paper airplane, this could be a simple experiment:įly the plane in the house, and measure distance and flight time. So far this has all been a lot of thinking. Theory = Tested & True Test the Hypothesis It’ll never make it to theory.)įor an easy to remember mnemonic think “ H” and “ T“ Some are hypotheses are proven wrong (Like that one about kids gaining super powers by stepping outside. So, in that sense, with enough testing and evidence, a good hypothesis can “grow up” to become a theory. It’s our best guess what we think will happen, given what we know.Ī theory has already been tested as true and has some solid data behind it. How can you make sure you’re using the correct term?Ī hypothesis is, by definition, untested. Hypothesis and theory are sometimes used interchangeably, though they do not mean the same thing. What’s the difference between a hypothesis and a theory? Now we’re approaching a hypothesis: The wind helps keep the plane in the air longer and enables it to fly farther. What about the wind?Ĭould the wind carry the plane further than it would go in the house with no wind? Maybe we’re on to something with the last one. Maybe my son gained super plane throwing powers when exposed to fresh air? Not bloody likely. Perhaps the sun makes it go further? Nope, no solar power here. There’s more room for it to fly outside? True, but Nah. So, why did our airplane fly further outside? Debate, reason, argue, and come up with a consensus on the best plausible solution. If you’re doing an experiment in a group or classroom setting, discuss different possibilities and outcomes. Note it’s not necessarily THE answer, but a possible answer. ![]() The hypothesis will be a possible answer. Give it time and don’t be afraid of silly ideas. It’s our brainstorming, our thought process. The hypothesis may take a bit longer than the rest of the steps. Kids (and adults) must use what they already know to create a logical explanation. Now that we have our question, what’s the answer? Why does that happen or why does it work that way? Critical thinking skills play heavily in this part. Let’s think about that: Present a Hypothesis Yes, so, back to our paper airplane: Why did our paper airplane fly farther outside than it did inside? How is another good question, and often follows “why:” How does a phone work? How does the fridge keep food cold? How can a bird fly? Birds? Planes are heavier – how can an airplane fly? In their natural curiosity, they are always asking, “Why?” Why is the sky blue? Why does the sun come up every morning? Why is it dark at night? Why is it colder at night? Why is… well, you get the idea. My son was contemplating paper airplanes and was wondering why, on this specific day, when he threw one outside it went much further than in the house. Follow those thoughts there’s usually a question there. Once we notice something, we can begin to wonder about it. For this article, we will be using paper airplanes as an example of a simple science experiment and discussing some other projects as well. Let’s look at different ways we can use the scientific method for STEAM and STEM activities. If you’re asking questions and trying to solve problems, you’re well on your way. The Scientific Method includes the following steps: Using the scientific method to relay facts and information is a great way to analyze and solve problems, especially for kids just learning about science. With a little scientific thinking, we can tap into a whole new way of understanding the world around us. Presented with the right angle, science can be a fascinating subject accessible to all. Science is sometimes viewed as a difficult subject reserved for the smartest or nerdiest students. ![]() Whether we notice or not, science is all around and part of nearly everything we experience.
