This week we're back using microscopes to check out plant and animal cells. To begin, we'll look at thin slices of cork - similar to what Robert Hooke saw almost 400 years ago when he discovered cells. While looking at plant cells, you will prepare your own slides of onion and aloe, observing many cell parts, such as the nucleus and chloroplast. We will also check out prepared slides of frog blood, and you will prepare a slide of YOUR cheek cells. It will be a great week with lots of practice using the microscope. By the end of the week, make sure you are confident with how to use a microscope - changing objectives, focusing, and proper use of the microscope. Stay curious and keep looking for answers!

After investigating single celled prokaryotes and eukaryotes last week, we are finally going to check out multicellular eukaryotes - otherwise known as plant and animal cells. To start off, we'll label all of the organelles (or cell parts) found in both of these cells, then move on to find out how those parts function. On Friday, you will have a quiz on the parts (NOT THE FUNCTIONS!) of the animal and plant cells - so make sure to be good with the locations and spelling. The more you practice, the better you'll do. Stay curious and keep looking for answers!
This week we'll be finishing up the organization of the body and look more closely at prokaryotic and eukaryotic cells. On Tuesday, you will finish up and present your Explain Everything Mini-Challenge. Wednesday, we'll review/discuss the last test and about forming questions from your notes and worksheets. Thursday and Friday, you will begin taking a closer look at prokaryotes and eukaryotes by conducting your own investigation of two single celled organisms - discovering more about the microscopic world around you and how much we really owe them for own existence.

Welcome back from Nature's Classroom (for the second time!). This week we'll be starting a new unit - Cells! This week we will look at look at the history of the microscope, and we'll talk about the scientists who discovered cells and created the CELL THEORY. We will also look at the levels of organization of the body - starting with the least complex level, the cell. Then our last day this week (Thursday), we'll investigate the two major types of cells found on Earth - Eukaryotic and Prokaryotic cells. Stay curious and keep looking for answers!
