Lesson 1 - Monday, Apr 22 (All periods)
Focus Question: How can we see what living things are made of?
What We Did…
After completing last week’s microscope work on plant cells, students were asked to begin investigating some animal cell slides. Here is the order of the prepared slides we followed in our ANIMAL CELL INVESTIGATION…
BLOOD INVESTIGATION (3 drawings)
1) Human Blood Smear – many red and a few white blood cells.
2) Phagocytosis in blood – some white blood cells surrounding and engulfing (consuming) other cells.
3) Aorta artery & vein – the tubes through which blood cells travel.
BONE INVESTIGATION (2 drawings)
4) Compact bone (impregnated) – the hard, dense outer layer of bones.
5) Compact bone (decalcified femur) – the hard, dense outer layer of bones.
MUSCLE INVESTIGATION (2 drawings)
6) Striated muscle – also known as skeletal and cardiac muscle.
7) Non-striated muscle – also known as smooth muscle.
CONNECTING TISSUE INVESTIGATION (3 drawings)
8) Fibrocartilage – acts as a cushion between bones in the joints.
9) Hyaline cartilage – helps the bones move smoothly past each other in the joints.
10) Tendon – attaches muscle to bone.
NERVE INVESTIGATION (2 drawings)
11) Medullated nerve fibers – a nerve fiber surrounded by a protective covering called ‘myelin.’
12) Motor nerve-ending in muscle – nerve fibers that end in muscle tissue.
Homework: There is no science homework tonight, but some students have mentioned they are going to work on their microscope drawings from some of the photos they took in class.
Lesson 2 - Tues, Apr 23 (B & E) & Wed, Apr 24 (G)

In today’s lesson we followed the same Animal Cell Investigation plan as laid out in Lesson 1 (above).

Lesson 4 - Thurs, Apr 25 (B) & Fri, Apr # (E & G)
Focus Question: How can we see what living things are made of?
What We Did…
After completing their Animal Cell Investigation, students were asked to double-check their investigations for 1) accurate page titles, 2) accurate drawing labels that match the glass slide labels, and 3) labelling of the magnification power used for all 12 Animal Cell investigation drawings.
Students were then asked to update their Table of Contents to reflect all of their new Animal Cell investigations. After completing these tasks, students were asked to make yet another science notebook entry with the title, “ANIMAL CELL DIAGRAM,” and to use the same resources to complete the same tasks as they did when making the PLANT CELL DRAWING.”
After completing the ANIMAL CELL DIAGRAM assignment, students were asked to answer the Orange Questions (A, B, C, D, E) and Summary Questions (1, 2, 3) on pp. 18-19 in the “1.3 – Plant and Animal Cells” section of the Activate Science 1 (blue) textbook. This assignment was also put into the science notebook with the title, “1.2 – Plant and Animal Cells.
