Biology

Dear Students, 

Since you will be home for Easter, I organized an experiment for you to get extra points. I want you to learn what is a scientific poster and how to design one to show the result of the experiment. 

You have to carry out the experiment: “The growth of bread mould”, and then design a poster with your results. 

THE GROWTH OF BREAD MOULD 

-Experiment + Poster-

   You have probably seen mould growing on food. In this experiment you will discover the ideal conditions for growing bread mould. After you are done, you will have to design a poster to show the results of your research.

  • Question: Use the scientific method to answer the following question: Does   the humidity, or exposure to air affects the growth of mould? 
  • Hypothesis: 
  • Experiment Materials: 

-Fresh bread

-4 plates or containers 

-Markers to label each container 

-Lid or cover for the containers

  • Experiment Procedure: 

1. Place the bread in four different plates or containers and number them using

a marker.

     -Place a piece of dampened bread on an uncovered container/ plate (bread1).

     -Place a piece of dampened bread on a covered container (bread 2).

     -Place a piece of undampened bread on an uncovered container (bread 3).

     -Place a piece of undampened bread on a covered container (bread 4).

2. Over the course of a week, note down in your data table what happens each day with each one of the breads.

3. Do some drawings or take some photos to show the development of the mould.

  • Results: 
    1. Data Table: 
Bread 1(       )Bread 2(     )Bread 3 (      ) Bread 4 (       )
Day 1
Day 2
Day 3
Day 4
Day 5
Day 6
Day 7
  • Pictures or drawings:
  • Conclusion:   Analysis of results and confirmation of the hypothesis: 

Answer the following questions, and you can add any other fact or conclusion you consider important 

  • Was your hypothesis supported or not?
  • Which sample was the quickest to develop mould?
  • How does humidity affect the way the mould grows? 
  • Do you think the mould only started to develop once it had become visible or was it developing before then? 
  • Do you think the mould started to develop on the bread because the bread was mouldy already?
  • Explain how the mould nourishes itself and describe the conditions in which it grows best.
  • If you could repeat your experiment, what would you change? How could you improve it?
Safety Concern: Some people can be allergic to mould. If that is the case, do not perform this experiment. Do not eat or drink when working with the mouldy bread. Don’t forget to wash your hands!
  • Presentation of Results: 

     When you are done with your experiment, you need to design a poster to show the results of your research. 

Posters are large displays that present the most important information about investigation in an attractive way.

Use this guide as a guide to know the elements that a poster should have: 

You don’t have to do it exactly the same. Change anything you want to make your poster nice and pretty.

Design of your poster: 

-You could use Canva to design it.  

– You could also use Power Point or any Apps you know.

-You could also design the poster without the computer, using a big paper or cardboard, colours, markers, drawings and pictures. ☺

Science

Here you have some online sources suggestions for you to explore during this time at home. 

ONLINE SCIENCE RESOURCES: 

  1. NASA AT HOME: Remember that we studied in the 1st Evaluation about the first man on the moon, and we talked about NASA, planets, space.   So, NASA has put together a collection you may find interesting for these days at home.

  1. WEBSITE MYSTERY DOUG: This is a website that encourages students to ask questions. Doug answers questions submitted by students. Throughout the video, Doug will help you find the answer. The videos range from 1-5 minutes. This is a great video series that encourages you to become scientists and ask questions!!
