8Th Grade Integrated Science Review Name Hour

8th Grade Integrated Science Multi Media Project Name Answer Key Mrs. Orgill Hour ______One of the struggles with science are understanding the vocabulary. You will therefore present a presentation defining each concept, give an example from class, and then come up with a unique and interesting example from real life. You will receive additional points if your classmates find that your example more interesting. The week before the end of the trimester you will present project to your classmates. It can be a power point, a video, or on social media. In addition to teaching your classmates you will teach at least five other 8th grade students who are not in our class and get their signatures. If you share your information over social media you will not need signatures. If you have other ideas about how to present your vocabulary please talk with Mrs. Orgill for approval.

Word Definition Example from class Example from Real Life The ability for a substance to Chemical Paper is flammable and could burn to become a new substance Properties become ash & CO (through burning or reacting) 2 Paper could get wet, but it would still The ability for a substance to Physical be paper. It could also dry and still change in some way but it’s still Properties have paper properties like absorb ink the same substance. or be flammable. Cooking an egg: Chemical When a substance changes into Raw egg  cooked egg Change a new substance. Changes the egg into a different molecule. When a substance changes in Physical Ice Cube Metling some way but it’s still the same Change (It’s still H O) substance. 2 Phase Change Changing from a solid to liquid Ice (solid) & it melts into water (liquid) is a Physical to gas is physical because it’s which can turn into water vapor (gas) Change still the same molecule. but it would still be H2O. 1.

Egg Cooking The amount of mass in a given Density is a Metals are more dense than wood volume (g/mL) Physical (more atoms in the same space) More dense means it feels more Property heavy. Maleability is a The ability to flatten a solid Physical without it shattering. Pennies flatten on a railroad.
