What science skills did you use during the SMASH Day activity? How do these science skills help us be better scientists?
Well I am not sure whether I actually used my skills. Or maybe its just that i used my skills but i didn't realize it. But now that I thought about, i may have applied the law for density. Like i know to make the bottom stable which is heavier on the bottom. So that it would be more stable. I think that by applying the whole density idea it helped scientists better because this way scientist would know what would go first. Or what should be put on each other and for those things not destroyed or fall over. I also believed u used my skills in hypothesis, i used this when i was predicting whether the thing will fall or whether it will broke up. And this skill made us become better scientist because by using hypothesis we can try to make better judgment of what might happen next without keep trying things over and over.
