I thought I knew about matter and energy, But there's a lot more to it when you convert matter a lot energy. I didn't particularly find this video engaging but It did teach me thing that I didn't know. I don't think this video was really supposed to be fun or anything it just made me not want to pay attention or learn anything. But working past my boredness I did learn what I thought was interesting stuff. Such as The greenhouse effect I thought was interesting and I didn't know that at 2:34 in the video I learned that most of the energy from the sun Is being bounced back out when it reaches the atmosphere or the greenhouse gasses. The energy that's left hits the earth in which the earth absorbs it and sends it back out again but the green house gasses bounces some of it back at earth again. Also at 9:40 in the video he addresses the difference between mass and wight, he explains the on earth your mass and weight are the same on earth because of the gavrity. But If you go to the moon or any different plante really than your weight will be different but your mass will stay the same, your mass always stays the same. These two things are the things that really stuck with me because I thought these two concepts were interesting.
(^^not my picture^^) In this lab my group and I tried to make liquid magnets, and sadly it didn't work.
We used these material in which we found online:
(http://chemistry.about.com/od/demonstrationsexperiments/ss/liquidmagnet_2.htm) When Researching this lab we thought It would be really cool, Beside the fact that there are many safety protocols like wearing safety glasses, gloves, lab coats, and using a fume hood. The reason Why we had to suit up was because There was a risk that it could stain our skin and clothes. When we started this lab we didn't take into account of how long it would take so we ended up running out of time and had to do over the time span of two days. I think this is probably why it didn't work. We think that because we didn't have enough time to heat up the ferrofluid and waited till the next day to do it it dried out too much and lost its chemical reaction. We really wanted it to work because we thought it would be really cool and interesting to experiment/play with but without touching it because its toxic. We could however, put it in a glass container to separate it so we could put a magnet up to the glass which the ferrofluid would be attracted to and that's how we could play with it. I would want to do this again and to have more time to work on it in class. I would do this by staying it at lunch or asking my next period teacher if i could stay and work on it. |
