Ok folks, here we go!!!
Time to take our cellular biology knowledge and start to use it towards understanding how cells come together to form specialized tissues, organs, and then how this all works together in systems. Please get onto your G-Class and use the login information to join our Khan Academy Biology class. I've posted an assignment on there that we'll get started on tomorrow studying Anatomy and Physiology (A&P). Big new as well...we're going to do an extended Pig Dissection Lab!! That's right :) After we gain some knowledge on how we're put together and how things work together, we'll work with fetal pigs to get an even deeper understanding of our organs by participating in a dissection lab. Cheers...I'm so excited :) In this lab, you'll be working in small groups looking through microscopes examining slides of various things. Your job is to determine whether the cells in the slides are plant or animal cells based on your knowledge and experience.
Using the handout or online doc, you'll have to identify them as plant or animal and then write down your observations and supporting evidence. Think about what you've learned about cells. What makes a plant cell different then an animal cell? There are a 4 follow up questions after the lab that should be familiar. Use the internet if needed to help you answer them. Chur Hey there everyone,
Congrats on the first month of Bio and all that we've been learning. It's time to review the material and assess our content knowledge and learning. This week we'll be reviewing material Monday through Wednesday getting ready for a comprehensive assessment on Thursday and Friday. It will take a couple of days to get through the assessment so plan on 2 days for it. Time to brush up and review concepts that we've learned.
Cheers and let's do this :) Students are experimenting on an egg first stripping away the hard calcium carbonate shell to reveal the soft semi-permeable membrane beneath.
From here...students submerge the egg into a variety of solutions to see how it affects the egg's shape, mass, and size. Questions for students to consider : 1) When you placed the egg in the acetic acid, did a reaction occur? How do you know? What signs gave you clues to this? 2) How did the mass change after each solution and why? 3) Explain this change in mass in terms of Osmosis. Hey there everyone,
Welcome back from an amazing 3-day weekend. We've been digging deep into cell theory and organelles. I've been excited listening to the conversations of your groups sharing out information on the cells. Way to go with the team work. Teamwork = Dreamwork...yeah I know it's kinda corny yet very appropriate and accurate. The next step is to look at diagrams of cells and be able to identify those same organelles. With this skill, we move into actual lab work where we'll look at slides in a microscope with the hopes of identifying organelles as well. We also have to acquire the skill to differentiate between plant and animal cells as well as single-celled organisms and prokaryotes...remember the bacteria conversation from last week??? So buckle up and let the exploration and learning begin :) Always check the G Class for assignments and expectations on work. We're diving deep into the different organelles found in eukaryotic cells. On your G-Class, I posted an announcement with the guiding doc for this mini-unit. Please read through it and contact me with questions.
The goal is to familiarize ourselves with 9 different organelles of a eukaryotic cell and be able to describe their shape, size relative to the cell, function, and any other interesting facts about them. Once we dial this in, and become experts on them, we'll look at cancer cells and compare them. See their similarities and differences. Chur |
