Mental Math for Warm Up – be ready!
Warm Up:
I will say each MENTAL math problem two times…and only two times. Do NOT write anything but your answer – everything else is MENTAL!
I CAN: begin our study of the cell and the microscope.

2. Mental Math – NO TALKING!
Remember – you ONLY write the answer, not the problem or calculations. Each problem will be SAID two times…and only two. If you speak out of turn, you may not hear – and risk a zero.

3. Today’s checklist: Any order, but be careful – textbook is here and web sites can be reached from home.
FINISH yesterday’s work on cells…
Pg 286 – find the four vocabulary terms and define them using the chapter.
Fill in the worksheet “Lesson 2 – Cells” using the textbook pages
Go to my web page and link to the sites given (2/20/19). You are trying to see things photographed through a microscope!!
Egg hypothesis – what will happen if it’s in vinegar for a day or two?

5. Cells
Smallest thing…that can still be called living. The basic unit of living things is called the cell.
We categorize them into groups. You and I are ANIMAL, but there are plant, protist, and more.
Different cells have a LOT in common, but a few differences.

6. How are we able to see cells?
Richard Hooke and Anton van Leeuwenhoek – “played” with variations of a microscope.
Over time, a CELL THEORY was created:
All living things are made of cells.
Cells are the smallest unit of living things.
Cells must come from other (pre-existing) cells.
