Section 11.5

Class of: 04-Apr-2016.

Today we covered Section 11.5: Nuclear Reactions: Fusion (p. 327).

Learning Objectives:

  • Students will be able to demonstrate knowledge of nuclear fusion by completing nuclear equations, listing sources of fusion energy, and explaining the process of fusion in stars.

Please work through the following review problems:

p. 331 #1-20

Bio 11: Kingdom Monera Part 4

Class of: 01-Apr-2016.

Today we covered Section CB.4: The Importance and Control of Bacteria.

Learning Objectives:

  • Students will be able to discuss the various ways that bacteria are important to the planet.
  • Students will be able to explain how bacteria can be harmful and controlled.
  • Students will be able to describe antibiotic resistance and how it can be avoided.

Did you know that the rampant use of antibiotics in humans and livestock has caused strains of bacterial “superbugs” to evolve? They are immune to conventional forms of antibiotics and therefore are difficult to treat. More often than not they are at hospitals where there are plenty of opportunities for evolution to take place in the patients being treated. Ironically, the last place you want to be sick is the hospital!

Please make sure that you review the learning objectives above!

Section 11.2 & 11.3

Class of: 01-Apr-2016.

Today we started Chapter 11: we covered Section 11.2: Nuclear Reactions: Fission (p. 307) and Section 11.3: Nuclear Power Generation (p. 318).

Learning Objectives:

  • Students will be able to demonstrate knowledge of nuclear fission by completing nuclear equations.
  • Students will be able to explain how a chain reaction can generate energy through atomic mass changes.
  • Students will be able to supply an example of a nuclear fission reactor (i.e. CANDU).

Did you know? The Chernobyl disaster was a nuclear meltdown that occurred in the town of Pripyat in the Ukraine (then was a part of the USSR). The background radiation levels are still so high after all of the radioactive materials exploded outwards that there is a 30 km zone extending in all directions from the plant where humans are not allowed, and is not expected to be safe for humans for another 20,000 years.

Please work through the following review problems:

p. 317 # 1-15

p. 323 # 1- 15

Have a great weekend!

Bio 11: Kingdom Monera Part 3

Class of: 31-Mar-2016.

Today we covered Section CB.3: Bacterial Reproduction and Conjugation.

Learning Objectives:

  • Students will be able to explain how bacteria divide asexually by binary fission and understand what factors limit their growth.
  • Students will be able to explain how bacteria increase their genetic diversity through the process of conjugation.

Did you know that bacterial replicate so quickly that if a single bacterium were able to replicate every 15 minutes unchecked, the colony would weigh more than the Earth after 2 days!

Please make sure that you review the learning objectives above!

Section 11.1

Class of: 31-Mar-2016.

Today we started Chapter 11: we covered Section 11.1: Nuclear Reactions (p. 307).

Learning Objectives:

  • Students will be able to explain the concept of artificial radioactivity and combine atoms to form unstable isotopes.
  • Students will be able to describe ways of reducing radiation exposure.
  • Students will be able to relate energy to mass using Einstein’s equation.

Did you know? One joule of energy is the amount of energy it takes to lift a 1 pound object 9 inches upwards against gravity. That’s about the energy it takes to lift an apple one foot into the air. Cool!

Please work through the following review problems:

p. 311 # 1-15

Bio 11: Kingdom Monera Part 2

Class of: 30-Mar-2016.

Today we covered Section CB.2: Identifying Types of Monerans.

Learning Objectives:

  • Students will be able to identify the shapes and movement types of bacteria.
  • Students will be able to identify bacteria as gram-positive or gram-negative.
  • Students will be able to classify bacteria based on their energy source and oxygen use.

Did you know that bacteria are used to ferment yogurt! It’s true! And the yogurt companies keep these bacteria in the yogurt to help provide your gut with a healthy normal flora.

Please make sure that you know how to classify bacteria based on their shape, movement, staining, and energy sources!

Chapter 10 Lab

Check out the instructions and marking check-list here:

Sci 10 10.L

The lab report will be due on Tuesday, 5-Apr-2016.

We will have a small quiz next class: Thursday, 31-Mar-2016!

You will need to know about to calculate the number of protons, neutrons, and mass number. You will need to know about the three different types of decay: alpha, beta, and gamma, and how to write equations for each of them. You will also need to know how to solve problems about half-life (like the sample problems we went over in section 10.4).

Bio 11: Kingdom Monera Part 1

Class of: 29-Mar-2016.

Today we covered Section CB.1: Introduction to Monerans.

Learning Objectives:

  • Students will be able to identify the unifying characteristics of the Kingdom Monera and state the importance and uses of belonging species.
  • Students will be able to differentiate between a prokaryotic and eukaryotic cell.

Did you know that cell for cell there are more prokaryotic bacteria in your body than there are eukaryotic human cells? It’s astounding! Bacteria are really important, and even though some will hurt you if they get in the wrong place, they generally do a lot of good for you and the world.

Please make sure that you know how to identify a prokaryotic cell by its structure! You should be able to identify parts of a prokaryotic cell on a diagram, or label the diagram yourself.

 

Section 10.4

Class of: 29-Mar-2016.

Today we covered Section 10.4: Half-Life (p. 290).

Learning Objectives:

  • Students will be able to use the concept of half-life to calculate the amount of time passed, material remaining, or activity of a sample undergoing radioactive decay.

Did you know? Radioactive dating has been essential in helping scientists discover evolutionary relationships! Did organism A exist before organism B? Did that mean that organism B evolved legs, or did organism A lose them?

Please work through the following review problems:
