Introduction
Good morning students, my name is Miss Mtiya I am a student teacher from CPUT, today I will e your teacher. We will cover vectors and scalars, we will look on the what is a vector and what is a scalar and the difference between the two. Please have a look on this short video for more understanding on the concept on Vector and Scala
Task
this task is design to enhance the learner's understanding of the content.
1. Classify the following as vectors or scalars
a. length
b. force
c. direction
d. height
e. time
f. speed
g. temperature
2. Which of the following contains two vectors and a scalar?
a. distance, acceleration and speed
b. displacement, velocity and acceleration
c. displacement, speed and velocity
3. Two vectors act on the same point. What should the angle between them be so that a maximum resultant is obtained?
a. 0◦
b. 90⸰
c. 180
4. Two forces, 4N and 11N, act on a point. Which one of the following cannot be the magnitude of a resultant?
a. 4 N
b. 7 N
c. 11 N
d. 15 N
5. Which one of the following is not a vector quantity
a. velocity
b. force
c. energy
d. momentum

Process
in order for learner's to complete this task they need an understanding of the content, they need to consult the slides that I used during my lesson.
students will also have to use their textbook from page 100-110 for more information because I could not cover everything on one lesson.
learners must also make use of You tube for broader understanding.
learners can also collaborate their knowledge by discussing on how they do it.
students can also have a look on the video below for more understanding
Students must use google classroom to complete this activity.
Evaluation
the aim of this lesson is to give learners an understanding about what are vectors and what are scalars.
how to distinguish between a vector and a scalar.
how to calculate a resultant force using a vector diagram.
this lesson is a basic introduction to be broader topic of mechanics, it prepares learners to be able to deal with more deeper mechanics in grade 11.
the lesson that I have presented to the learners it meets the objectives of the lesson, because learners were able to do the activity with out having any difficulties that shows that learners were concentrating in class and they were participating and they showed interest on the lesson.
Conclusion
the teaching and learning of this lesson was easy because learners were interested and they were engaging on the lesson, they were asking questions and they were answering questions as well.
from this lesson I learnt that it is very important to engage learners when teaching and to make sure that all learners they understand what is being taught, no learner is left behind.
I also learnt that it is very important to keep on asking questions when teaching and rewards the learners that get the questions right, that will make all the learner concentrate in class because they would also like to get the reward.
Credits
for this lesson I give credit to grade 10 study and master textbook
and You Tube and google
for helping me to make this lesson more meaningful and rich of knowledge.
