9/20: F Day, ASSEMBLY SCHEDULE, PEP RALLY, HOMECOMING DANCE
6th Grade Science
We’ve been diving deeper into the topics of weathering, erosion, and deposition. Our focus has been to continue Unit 1 (‘Earth’s Surface’) but move on to Lesson 3 (‘Erosion and Deposition by Water’) and Lesson 4 (‘Erosion and Deposition by Wind, Ice, and Gravity’.) To model an example of water action, we created our own stalactites and stalagmites! See a picture below. We’ve also learned how the Grand Canyon was gradually formed through the combination of the aforementioned forces and how amazing that is. We discussed how dangerous landslides can be and how devastating the effects are for the communities affected. We modeled a landslide by placing rocks on a wooden board and tilting the board until the rocks overcame the force of friction and fell down (the simulated landslide). We measured the angles of the boards with protractors and found which types of rocks fell more easily. The other picture below was a spontaneous inquiry after lab into balancing different objects and how something as light as a piece of paper could tip the scales! (They’re already thinking about physics?!) Ask them about their landslide lab!
7th Grade Science
Whew! We are continuing on and learning more about Unit 1 (‘Cells’) and are focusing on Lessons 3 and 4 (‘Cell Structure and Function’ and ‘Levels of Cellular Organization’). We really are digging deep to understand how structure affects and determines function for the organelles within our cells. Just like a table being flat allows for writing, the fact that the endoplasmic reticulum is folded allows for more space for ribosomes and protein production. We made amazing posters of animal and plants cells and got to the bottom of the differences between the two! Additionally, we did an activity that highlighted how specialization is important for multicellular organisms! Ask them about the activity that stressed them out and that’s the one!
We are also continuing Unit 1 (‘Matter’) and diving into Lessons 3 and 4 (‘Physical and Chemical Changes,’ ‘Pure Substances and Mixtures’). We had the chance to play around with slime! Two liquid substances underwent a chemical change to become a new substance with new properties and that substance is slime! (We just want to make slime, right? 🙂 ). We familiarized ourselves with the famous French scientist Antoine Lavoisier who discovered the law of conservation of mass! Ask your student where the logs go when you burn a fire… does mass disappear? Today we started discovering the patterns within the periodic table and I did a demonstration coupled with an embellished 100% historically accurate 😉 storytelling of the Wedding at Cana and Jesus’s first miracle. Definitely remember to ask your students about this one!
