Science at Bangor & in the News
This week we spent the week balancing reactions. We practiced balancing the reactions using a few different methods: using cubes to represent the atoms in each compound & making the products from the cubes or trying to get equal numbers of each cube on both sides of the reactions, drawing out particle representations of the atoms and balancing the numbers of particles, and counting up the number of each atom without drawing or using cubes. Each student picked their favorite method & worked from there. At the end of the week we added an additional challenge: starting with a written out reaction, having to write the chemical formulas, and finally balancing the reaction. This puts together skills from our last unit (naming chemical compounds) with balancing reactions. Science 9 is just about finished with our unit on forces. This week we discussed Newton's 2nd law (Force = mass * acceleration), reviewed the rest of the unit, and took the end of unit assessment. On Friday, we watched videos on the physics and biology of car crashes in order to prepare for our project for the unit: An egg drop. We will be building egg protection containers that will hopefully protect raw eggs from being cracked after being dropped off of the band tower.
