What is Microbiology?
What sort of small, living things do microbiologists
study? There are five different types of organisms (living things) bacteria, fungi, protists, archaea and algae. Each of these organisms does different things and is found in different places. Who am I? Identify each organism from these clues.
Create your own micro organism:
Story writing: You are a micro organism. Are you a good organism or a bad organism? Explain where you live and who you live with. EG You are a friendly bacteria who lives with its family in the kitchen and you help protect the environment from bad organisms by eating them and keeping the family safe. Mathematics Bacteria come in many shapes - round, rod, comma, spiral and even square! When joined together they can also take up a variety of shapes, such as clusters, chains, cubic packets, squares and bunches of grapes. Activity 1 younge students Choose one shape form the above list and one colour and using a drawing program on your computer draw some repeating patterns. Activity 2 older students Choose two shapes which will fit neatly together and using a drawing program on your computer, design some tesselations. Activity 3 older students If one bacteria landed on your sandwich how many bacteria would it take to cover the whole surface? Work out a computer model using a spreadsheet with variables which take into account the size of the slice of bread, the size of the bacteria and the rate of growth. Eg size of bread 10 x 10 cm (for a hungry giant!). Size of bacteria 0.003 mm, rate of growth doubles every time interval. If your model works try it out on a bigger area such as how many bacteria would it take to colonise your bed, the school playground, the earth and the moon. Activity 4 older students Now create a model which shows what would happen if all five micro organisms were let loose on the earth to colonise freely. What would survive and what would die. Write up your results and use graphs to illustrate your findings. All microbes are bad for us, aren't they? Click on the link RAINFOREST DISEASES. Activity 1 The mosquito transmits a disease called malaria. Find out what this disease is and how it affects humans. Are there any other diseases which are transmitted by animals or insects to humans? Draw an 8 box storyboard showing how microbes from a mosquito get into humans. Call your work Marvin Mosquito Conquers the Human Body.
Activity 2 In the old days people died as a result of some of the diseases spread by microbes and bacteria. As we have advanced in medicine and technology we have stopped some of these diseases altogether and some we have made less life threatening. Look at one of these periods in history and see what were the most common diseases of the time and what were their effects. What was done to improve health, has it changed over the years? Work in groups of four and produce a piece of display work. Use text and pictures. Look back: 20 years in the 1980s 50 years in the 1950s 100 years in the 1900s 200 years in the 1800s 400 years in the 1600s
Activity 3 Reading for Understanding: Influenza Read the passage about Influenza and answer the following questions:
Click on:- Some Famous Microbiologists and their Discoveries.
Now research the list of Microbiologists and write about 5 more important discoveries. Produce a fact sheet about each discovery and put these into a class book - illustrate with drawings. Research how penicillin grows and start an experiment to plot the growth of these cells. Take pictures with a digital camera and write an account of the experiment using a word processor. Publish this on the Guardians Website.
