BIO5 Continuity of Life and Homeostasis
BIO5 Continuity of Life and Homeostasis 2020
Major Practical – Investigating Germination
Your task will be to design an experiment, ca
y it out and complete a written lab report. You may ca
y out the
experiment on your own or in groups of 2-4, but each student must write up the experimental report independently. You
will have some class time to set up your experiment but will also need to monitor your experiment and record your data
for several days. This may be in and out of class time.
Your task is to investigate a factor which affects germination.
Some important information:
You will have class time to plan and to set up your experiment and some time at the start of following lessons to record
your results. You may have to check your experiment and record results on days which you do not have a class or at other
times during the day so you will need to organise with your group how to do this. You will not be able to check your
experiments at school over the weekend.
Refer to the marking scheme and your class notes when planning your experiment.
Available equipment:
• Seeds (wheat, barley, peas, alfalfa)
• Petri dishes
• Plastic cups, plates, bowls
• Ice cube trays
• Paper towel, cotton wool, abso
ent dishcloths
• Light banks, lamps, cupboards and boxes
• Water baths, fridge, freezer
• Electronic balances
• Materials for solutions (salt, sugar etc….)
• Other equipment may be available upon request –
please see your teacher.
Final report:
You will need to complete a written lab report on your investigation. A detailed guide that you were given in Year 11 on
how to write a biology lab report is available on the Google Classrooms Page. You should also consult the mark scheme to
ensure you are meeting the expected requirements. If you have any other questions about your experiment or your
eport, please come and see your teacher prior to the due date.
