Tuberculosis

This afternoon we will be doing an assessment in class on tuberculosis, a disease caused by a microbe.  Don't worry as you'll be able to use your books with all the information you're about to collect, as well as asking questions!
To prepare yourselves this lesson, find out using the internet and write in your books -

A short description (1 or 2 sentences) about where in the body tuberculosis can occur:

What the symptoms of tuberculosis are:

How it is caused:

How it can be spread:

The name of the pathogen:

The number of people per year that die from this disease:

Any ways of either treating or preventing the disease:

For this lesson, try and answer the following questions in your books.  Use the internet to help you, there are several links below that may help.

1. What are three problems/diseases that bacteria can cause for humans?
2. Where might you find the bacteria vibrio cholerae?
3. Define the word pathogens:
4. How can people stop the spread of pathogens?
5. Why do you think that microbes like bacteria and protozoa have only been discovered since the microscope was invented?
6. How do protozoa move?

nviz revision

Here are the answers to the revision sheet if you want to check yours:

Q1. television - d
       Speakers - b
       Spark - e
       Digger - c
       Kettle - a

Q2. a-If the television were more efficient, less heat would be produced as this is wasted energy.
       b-Energy going in, coming out as sound and heat.
Q3. The atmosphere is a layer of gases which surrounds the earth.  By produing more carbon dioxide and releasing it into the atmosphere, we allow the Earth to warm up.  This is called the greenhouse effect and leads to global warming and climate change.
Q4. Renewable energy sources, such as solar, wind and hydroelectric power produce no carbon dioxide while producing electricity.  This will decrease the rate of climate change and prepare us for wen fossil fuels run out.
Q5. Wind and solar power only provide electricity when it is sunny or windy.  This means that they can not be available at times when they are needed.  To fix this this problem, either a battery to store power is needed, or another renewable energy source that provides constant energy, like geothermal or hydroelectric power.
Q6.  Climate change may cause Sea levels to rise, Ocean acidification, increased frequency and severity of extreme weather (storms, hurricanes), droughts, diseases and food shortages.  These problems could lead to many social and other problems.
