G’day, Jacob from Make Science Fun! Thanks for tuning in today. Now, you’ve got a science fair project, or you’ve got a science research project or you’ve got some science experiment that you’ve got to do, and you don’t know what project to choose? I am here to help you. I am a science teacher, I have been teaching for about 15 years or so. I have marked hundreds of these projects, now I can tell you what a teacher is looking for. A teacher is looking for an interesting project with some form of real-life application, so in this article, I am going to show you three really good ideas, and how to do them.
All the best! So the first possible project to choose from is, sound insulation of a garage, investigating the best way to insulate your garage for sound. When we put this studio together, we wanted to be able to film at any time of the day. Without noise! (rooster crows) affecting us. And so, I went to a special effort, to make sure that the windows had special foam insulation. And, I put curtains up around the room to absorb the sound.
And, that also means that I can make noise without bothering anyone else. (knock knock) keep it down darling! Bothering anyone else. So your project is to pretend that you are starting up a garage band, and this is a model of the garage. Lets say you want to make a lot of noise in your garage. Maybe, play your favourite song. Its time to see what I can do, to test the science and break through.
No right no wrong, heroes for me! I can do my SRP !!! Now, lets say your making some awesome music like that, but, your family doesn’t want to hear you. So, in this project you have to investigate different ways to sound insulate your garage. So you might try things like, you have your speaker making the noise, and on the outside, to measure the sound, you can have a sound app on, and you probably want to measure the sound without any insulation, to be your control for the experiment. And then you want to insulate your room, and so you might try carpet and find the sound. You might try aluminium foil, you might try special foam, you might try curtain material, you might try cardboard.
So you can try a whole lot of different sound insulations, and determine which one is the most effective. You can look at the cost you can look at the ease of use, you can look at the environmental effectiveness so it’s a useful, interesting project. That is project number 1. G’day Jacob from Make Science Fun here. Checking out this snowboard ramp and the ice. I am pretty interested in it because of the ice and the sulfate of ammonia that they put on the ice.
I am interested to see, why they put sulfate of Ammonia on it. I mean, what does it do? Does it make the ice more slippery? or what? Does it make it last longer? I don’t know why there are putting it on?
Here we go! YEW! That’s not a bad grind. Alright! Oh! G’day Sam!
How are you? Hi-5! On that footage of the snowboarding. Oh no! It broke.
Ahhhh what have you done? Lets fix it. On that footage of the snowboarding, did you notice that what they did was they got ice, Would you like to help me out Sam? Lets put the ice onto the ramp. And what they did was they added salt, and they added sulfate of ammonia to the ice. And, my question is, why? Why did they add salt, and sulfate of ammonia?
It is freezing alright! And so, the experiment would be, or the research project would be, to find the answer to, why they actually add the salt and sulfate of ammonia So you’d start with just plain ice, and you’d have some form of mock-up wakeboard, and you would slide it down the ramp. You would probably do a longer one. And you would time how long it takes to slide down. You would do it quite a few times, so that you can get an average and you would also time how long it took for the ice to melt.
Ahhh! My hands are starting to get cold. So once you did it without salt and without sulphate of ammonia, then you would actually put some new ice on and you’d put some salt and you’d see how long it lasts, and what it does to the slipperiness. And you would put some sulfate of ammonia on, and see what it does to the slipperiness. So basically, the science research project, would be to investigate how effective it is to use salt and sulfate of ammonia, on an ice ramp. Now that is a pretty interesting project, isn’t it Sam?!
Lets give it another go, ready! ZOOM! That was a good one! In your third choice, for your science research project. The question that we want you to answer is what’s the best kind of light for plants to grow under? Is it yellow? green, red,blue purple, pink?
Who knows? That is what you need to find out! So you will need to set up a series of hot houses, you would have to have a control that is one where the cellophane has got no colour. And in each hot house, you would have a number of plants, all the same, all identical, across the entire experiment. And you would water each one the same amount, you would have them in the same location, so that the only variable, the independent variable, is the colour of the cellophane Now the dependent variable, is the one which you’ll be measuring every afternoon, and that is the height of the plant, and so you will actually record the heights of the plants as they grow, and at the end of the couple of weeks of growing, you will be able to graph, and be able to see quite clearly what is the optimum colour for plants to grown under. That sounds like a pretty interesting project! Doesn’t it Sam?
Would you like to do that? What colour do you think the plants would grow best under? Blue. You think blue? How come?! Because I like blue.
And blue is a bug. You just wrecked my hot house! Hopefully you can make a stronger one than I have! That’s all from me from Make Science Fun! look forward to your comments, and I look forward to finding out your results from your experiment. Bye for now!
