11:25-12:05  PM Block 5
12:05-12:35 PM LUNCH 
All Students to the Cafeteria & Dismissal from the building beginning PM.

2. Biology Do Now
Directions: Take out a sheet of notebook (Do Now sheet) and, then answer the question.
Explain how your digestive system can be called a “system” based on yesterday’s lesson.

3. Biology Do Now KEY
Explain how your digestive system can be called a “system” based on yesterday’s lesson. Our digestive system can be called a system because it is made of several organs (esophagus, stomach, sm/lg intestines, liver, gall bladder) that work together to help us break down foods so that we can absorb the nutrients and eliminate the solid waste.

4. Last night’s Homework – Turn in
How do the cells in a multicellular organism help the organism act like a system? How do the two relate? How do they work together?

5. Homework - Copy
Students will research to define and describe an example for each term: atom, molecule, covalent bond, ionic bond, polar molecule, nonpolar molecule, electronegativity, and hydrogen bond.

6. Engage – Answer on a sheet of notebook paper
Ask students,
“What are living things made of? And
“Why do you think we have to study chemistry in Biology?”

7. Explore - “Humans Really Are Made of Stardust…”
Students will read the article and answer the guide questions.
1) What fraction of the elements found in stars do humans share?
2) What elements are living things made of?
3) What does CHNOPS stand for?
4) What does APOGEE stand for?
5) Why do we have to study chemistry in biology?

8. What is the Periodic Table?
It represents our understanding of the structure and usefulness of the atoms that have been identified in our environment
Elements are organized on the Periodic Table based on similar properties
Picture from

9. What do the numbers and Letters mean?
Element Name
Atomic Number:
The number of protons in its atom.
Atomic Number
Element’s Chemical Symbol
Atomic Mass
Atomic Mass:
The mass of one atom of the element

10. The Periodic Table can also be divided into three main types of Elements: Metals, Metalloids, and Nonmetals

11. Metals Metals are shiny Metals are solid at room temperature
Metals have high conductivity
Metals can be flattened and not shatter (malleable)

12. Nonmetals Nonmetals are not shiny
Nonmetals are mostly gaseous at room temperature
Nonmetals are poor conductors
Nonmetals are brittle and will shatter easily (not malleable or ductile)

13. Metalloids
Metalloids have characteristics between metals and nonmetals
Metalloids are solid at room temperature
Metals are semi-conductors

14. Periods
Each horizontal row of the table is called a period

15. Groups (Families)
The Columns are called Groups
There are 18 groups

16. Extend
Students will complete the “systems investigation worksheet parts 1 & 2”

17. Evaluate – Exit Ticket
How is the periodic table of elements organized and what information can it provide us?
