Hey everyone!
Science
This week in science we watched two Bill Nye movies covering Friction (the force of rubbing, often transferred into heat) and Simple Machines (covered in earlier posts). Both of these topics will applied in our in our summative. Our summative will be mostly on our fluids unit that is what we have been studying for the last few weeks. Like Katie said in her last blog it must be something dealing with hydraulics.
Math
Currently in math the class was taught how to add and subtract fractions. For adding and subtracting you need to find a common denominator and then proceed to adding/subtracting the fractions. To find a common denominator, you sometimes need to multiply both the numerator and denominator of the fraction you wish to change to make it the correct number. For example, 2/10 + 2/5. You need to multiply the top and the bottom of the second fraction to get the denominator of 2/5 to be 10. Once you've multiplied by the correct number to get the same denominator, you can go ahead and add the fractions. Ex. 2/10 + 2/5 -> 2/10 + (2/5)x2 -> 2/10 + 4/10 = 6/10
Until next time,
