Essential Question
Essential Questions and Unit Understandings
Essential Question:
How does force influence motion
Enduring Understandings:
•
•
•
•
Motion may be described and analysed by the use of graphs and equations.
Classical physics requires a force to change a state of motion, as suggested by Newton in his laws of motion.
The fundamental concept of energy lays the basis upon which much of science is built.
Conservation of momentum is an example of a law that is never violated.

ask students to formulate a reasoned argument to support their opinion or conclusion
set students a task which required higher-order thinking skills (such as analysis or evaluation)
make a link to TOK
Research

require students to formulate/construct a focused research question (either in class or in a homework assignment)
give students advice on (or provide an opportunity for students to practise) narrowing the scope of a task to make
it more manageable
discuss or model the importance of academic honesty and clear acknowledgment of sources

Knowledgeable
Description
We nurture our curiosity, developing skills for inquiry and research on newtons laws of motion. Students will be given
opportunities to learn independently and with others through presentations on Newtons laws of motion.
We develop and use conceptual understanding of forces, exploring knowledge across a range of types of forces. We engage
with issues and ideas that have local and global significance on momentum change
We use critical and creative thinking skills to analyse and take responsible action on complex problems involving free body
diagrams and rate of chnage of momentum investigation. We exercise initiative in making reasoned, ethical decisions into
making decisions when doing space research using rockets

What worked well?
The ATL skills of research and thinking was well exemplified by the students during the learning experiences .Students were
able to research using different resources and present information in a meaningful way.Thinking skills was exemplified to an
extent with transfer of information still a challenge.
Application of knowledge was well exemplified by most students showing that the learner profile knowledgable was
achieved by most students.
The GRSP model provided students a chance to be able to demonstrate authentic real life applications of their inquiry and
thinking skills
Prior knowledge on scalars and vectors was well understood.
experiments on newtons laws of motion and forces worked well
Calculations involving Suvat was well understood
The prescribed experiment on determination worked well with students able to collect sufficient data
What didn't work so well?
The integration of CAS to play basketablll at home in order to understand projectile motion was not completed by some
students because of the pandemic.If we were in a school station,the students could have been taken to the basketball pitch
in school to complete the task.
Some students could not demonstrate thinking skills when transferring application questions in tests

John Drury, Gumba Otieno Charles
IB DP Grade 11 Physics HL (Grade 11)
Use of trigonometric ratios in resolving forces was challenging
Use of geogenra in modeling forces needs more explanation
Analysis of experimental data and propagation of uncertainty should be reviewed
NOS should be reinforced
What changes might be made for the future teaching of the unit?
Students should be given more experimental opportunities dealing with hands on experiments to model forces
Tasks should be differentiated to allow slow learners more opportunities to acquire the necessary skills over time by giving
them work outside class sessions
The students must be taken through basic maths skills with the help of maths department to support them in trigonometry,
quadratic equations and use of calculators.
