Transcript of BTEC Science

Unit 10: The Living Body Introduction
On completion of this unit a learner should:
1 Know the role of enzymes as catalysts
2 Be able to investigate individual body systems, relating their structure and functions to their role in maintaining health
3 Know how the nervous and endocrine systems work to coordinate the body systems
4 Know the structure and functions of the human reproductive system. Outcomes 1. Enzymes 3. Nervous system 4. Endocrine system 2. Body systems 5. Reproductive system Unit 3: Biology & the environment Unit 2: Energy & our universe Unit 1: Chemistry & our Earth Unit 7: Practical scientific investigations Share with the rest of the group what you are going for
Why are you going for it?
What will you do to ensure you will achieve it? Time to Share! 3 compulsory units


2 optional units Units I have checked through all your data
and the minimum expected grades from anyone
in this group is .................. Newsflash! What about you? What motivates you? You must not copy and paste large sections of text
You may quote sources but if you do this you must include the reference underneath
If you don’t stick to these rules you work will be rejected and you’ll have to re-do it Plagiarism Continual assessment
Practical investigations
Written work
Posters
Presentations
You must pass all assessments to get a grade! Assessment Vocational course – linked to how science is used in the work place
No exams – some students better suited to coursework
Varied topics with choice of units
Allows progression to further qualifications Why BTEC? Equivalent to 2 GCSEs
3 grades – pass, merit and distinction
Pass = CC
Merit = BB
Distinction = AA
EVERYONE will get at least the equivalent of 2 Cs! BTEC Applied Science On your Tracking Sheet Targets give you something to aim for

They are always set in the future

They are what separate being the best from being mediocre What is the link? Don’t decorate or declare your
undying love to anyone in your book or folder Exercise books and folders are
the property of Mrs Morrill You must achieve all pass criteria in a unit to pass that unit, all merit for merit etc
You must get a merit in at least 4 units and a pass in the other 2 to get a merit Grading This course is ?% coursework - no exams!!!
This means that your attendance must be high as you have to pass every piece of coursework to get a grade
Most of your work will be based on investigations which you will carry out
All of these will be based on real jobs and experiences How is it different from GCSE? Now sign off your Student Agreement Pass – Grade C! Newsflash! and you wouldn’t want to see her angry! Inappropriate use of exercise books and folders
might make Mrs Morrill angry......... Exercise Books and Folders Name:

p206 D5 Research how IVF works and explain the importance of hormones in this process. Your assignment...... You work at a horticultural research centre. You have been asked to investigate the growing conditions for a newly introduced plant.
You will be given 50 seeds of the plant. The stages for a pass P1 Assess the risks
P2 Produce a project plan
P3 Assemble your equipment

P5 Analyse your data (graphs)
P6 Produce a scientific report M1 Summarise how your initial research contributed to your plan

M2 Discuss the importance of maintaining an accurate logbook Merit D1 Evaluate your project, identifying any modification to the practical procedures and data collection methods used. Distinction Describe how hormones control functions in the body. Give 2 examples. You will have to do some pre-tests with different amounts. of metal and acid to work out how to use the right amount Milestones This is what you think will happen but better than a guess because you say why it will happen.

I think this … because… Hypothesis. This is a step by step instruction list like telling someone how to cook a meal.
You could number or bullet point the instructions.
Every step should be included even the little detail like quantities you used Method a. The plan must clearly identify the aim of the investigation,
b. Conduct research about the science involved in the investigation and job related to investigation. All research should be referenced and included a part of the planning.
c. Complete a list of resources and equipment needed.
d. Write an outline of the methodology.
e. Use the researched information to write a hypothesis for their investigation. The relevant scientific theory must be clearly outlined.
