Task 1
collaborative work
using TI-Nspire to
build your foundation on the key concept using examples presented in a collaborative environment.
========================================================
Task 2
Pair work
based on the activity in task 1, reflect on the processes involved and write it down on your worksheet 5.
Identify at least 2 points for consideration for 'Change of Subject'.
You may discuss with a partner in class.
Submit this at the end of the lesson.

Worksheet 5, ACE learning.
========================================================
Task 3
individual work
Extension of understanding on Change of Subject
Identify a formula in other subject areas (other than Mathematics)
- define which subject area the formula is applied and what the formula is about
- define all the variables used
- identify a variable (other than the one presented) to make a subject.
(ensure that this is possible)

V is the fluid flow speed at a point on a streamline,
G is the acceleration due to gravity,
Z is the elevation of the point above a reference plane, with the positive z-direction pointing upward – so in the direction opposite to the gravitational acceleration,
P is the pressure at the chosen point, and
D is the density of the fluid at all points in the fluid.
