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!

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!

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!

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.
