Embedded Files
In this assessment you are going to investigate biological ideas relating to interactions between humans and micro-organisms. In particular we are going to look at mould growing on food - and hopefully come up with an answer about the best place to keep food to prevent/slow down mould growth. We'll be focusing on bread.
We all know what happens to bread when it gets old. It goes mouldy!!! (Learn)
Tip : All of the information that you learn about this topic should go into your Discussion at the end of the investigation. It would be a good idea to make notes on what you are learning
Mission :
Your job is to determine what are the best conditions to store bread so it doesn't go mouldy.
In this investigation you are to develop and carry out an investigation. You will plan, collect, process and interpret information, and present a report on,
"I want to investigate how mould grows in different conditions. "
You will have a set number of periods to do the work, revising prior knowledge, completing practical work, and researching relevant theory information. (Learn) (Create) (Share)
Ways of doing the Assessment
Get the digital version by making a copy of the slide show below. You will need to add in extra slides to fit all the data/photos that you'll need to be collecting.
You can ask for a paper version if you prefer writing by hand.
It is worth 4 credits to you.
You will have a deadline to have it completed and handed in by. This is the last day of Term 2.
If you are doing a digital version, share it NOW with ka@hornby.school.nz and change the editing rights to Comment. (Any problems with doing that let me know asap) (Learn)
Step 1 : Setting the scene .... So why are we looking at mould? (Learn)
What is the relevance to me?
"Germs" can spread and get onto food.
Washing hands is important for hygiene.
Watch and see .....
Step 2 : Background information ..... Here are some questions and videos that might help guide your thinking. (Learn)
These are just your starting points ...... we expect to see more than what you learn form these few clips.
What happens if you eat mould?
What is mould?
What is the structure of mould?
How does mould reproduce?
How does mould get its food?
Here is most of the information you will need summarised into a slide show .... use this and the videos above as the starting place for your background research.
The Investigation
The Investigation
Now its time to do the experiment .... (Create)
Carry out the experiment.
Follow your method (you may need to create this and write it down) to collect data and record the results in a table or another appropriate way.
Remember to record any changes to your method and reasons for the changes as you go.
Record any difficulties with equipment, gathering your data or your method.
Any changes = record it on the slide show.
Now you need to sort out all the information (data) from you experiment so its more easily understood - hopefully you'll see something ..... This is why you should be taking lots of photos!!
Interpret the data
Process your results so that you can show the trend (or lack of) or pattern in your data. This will usually involve some calculations (e.g. averages) and/or a graph.
Record the relevant trend or pattern; this is your interpretation.
Relate the trend or pattern to your purpose; this is your conclusion.
This could be a series of photo slides .....
This is where we bring it all together explaining what we have found, what worked well, what didn't, what we fixed .....
Report on your investigation. (Share)
This will include your:
recorded data
processed data
interpretation of results
But this is the really important stuff....
But this is the really important stuff....
Conclusion
A conclusion that links your interpretation to the purpose (the reason we did the investigation) of the investigation that explains the conclusion trend. (Create) (Share)
Discussion
A discussion that includes: ( = you need to have answers for all these bullet points)
an answer to the question "Where do I store my bread?"
a justification of your answer linking to evidence from your experiment
what are the structures and their functions of fungus
two life processes (growth and nutrition)
what was the environmental factor and how did it affect the life processes
(Create) (Share)
Evaluation
What things (if any) did I need to change? What mistakes did I make? What would I do differently "next" time? What worked well? ..... (Learn) (Create) (Share)
Here is a link to a similar experiment that might give you some ideas of what to do for this one.... (Learn)
Checklist .... here is the marking guide for the assessment = have you done all that needs to be done to pass? Get Merit or Excellence?
