Which one is right for you?

HL vs. SLHL vs. SLYou should only take HL if you
have a strong interest in science.
![Page 3: Ib Biology Hl Pres 97](https://reader035.vdocument.in/reader035/viewer/2022062300/558471b0d8b42af90b8b4646/html5/thumbnails/3.jpg)
HL vs. SLHL vs. SLHL is strongly encouraged if you
are going to major in Biology or Chemistry in college.

HL vs. SLHL vs. SLIf you do not a have huge
interest in science you need to take a SL Environmental Systems.

So I am going HL, now So I am going HL, now what?what?You have two options
◦IB Biology◦IB Chemistry
Both courses are laid out in the same fashion.◦They are 2 year courses.◦You have to complete 60 hours of lab
work.◦You have to conduct a group 4 project◦IB testing consists of 3 final papers.

Biology and Chemistry Biology and Chemistry One and the same, almost.
If you take Chemistry you will have a good foundation for Biology in College.
If you take Biology you will learn quite a bit about chemistry.
In most cases biology majors get automatic minors in chemistry.

HL BiologyHL BiologyBiology is the study of life.
![Page 9: Ib Biology Hl Pres 97](https://reader035.vdocument.in/reader035/viewer/2022062300/558471b0d8b42af90b8b4646/html5/thumbnails/9.jpg)
HL BiologyHL BiologyHL Biology requires a huge
amount of memorization. You must be able to memorize
specific details as well as concepts.
In biology every concept is connected.

HL ChemistryHL Chemistry Chemistry is science of matter.

Those are your choicesThose are your choices

So you’re going with SL, So you’re going with SL, what next?what next?You really have three options.
◦Environmental Systems
This is a year long course40 hours of lab workGroup 4 project
![Page 14: Ib Biology Hl Pres 97](https://reader035.vdocument.in/reader035/viewer/2022062300/558471b0d8b42af90b8b4646/html5/thumbnails/14.jpg)
You can also SL in Chemistry or Biology◦Is still a 2 year course◦Only responsible for “core” material
on IB papers◦Will be in same class with HL
students
![Page 15: Ib Biology Hl Pres 97](https://reader035.vdocument.in/reader035/viewer/2022062300/558471b0d8b42af90b8b4646/html5/thumbnails/15.jpg)
IB CriteriaIB CriteriaAll IB science courses are scored
with same types of evaluations. ◦Internal Assessments◦External Assessments◦Group 4 project
![Page 16: Ib Biology Hl Pres 97](https://reader035.vdocument.in/reader035/viewer/2022062300/558471b0d8b42af90b8b4646/html5/thumbnails/16.jpg)
Internal AssessmentsInternal AssessmentsInternal Assessments are
basically formal lab write-ups.There are 5 parts to an IA.
◦Design◦Data Collection and Processing◦Conclusion and Evaluation◦Manipulative skills (graded during
Group 4 only)◦Personal Skills
2 marks are given for each category
![Page 17: Ib Biology Hl Pres 97](https://reader035.vdocument.in/reader035/viewer/2022062300/558471b0d8b42af90b8b4646/html5/thumbnails/17.jpg)
External AssessmentsExternal AssessmentsIB gives end of course exams. They
call them papers.There are 3 papers
◦Paper 1 is a multiple choice comprehensive final.
◦Paper 2 is a short answer essay comprehensive final.
◦Paper 3 is an essay final that concentrates on one or two topics in great depth. You get to pick the topic.
You will take these tests over 2 days.It is about 4 hours of testing.

Group 4 ProjectGroup 4 ProjectGroup 4 refers to science being
the 4th group in the IB curriculum.It is an IA that you do in groups
indepently.One student from each of the
science classes.◦Chemistry◦Biology◦Environmental systems
![Page 19: Ib Biology Hl Pres 97](https://reader035.vdocument.in/reader035/viewer/2022062300/558471b0d8b42af90b8b4646/html5/thumbnails/19.jpg)
Group 4 ProjectGroup 4 ProjectAll 3 classes come up with a
topic.Each group states a research
question.Each student creates an original
hypothesis.Each student then tests their
hypothesis.

Group 4 ProjectGroup 4 ProjectThe results of are displayed
“Science Fair” style and are accompanied by a complete IA lab write-up.
