This document describes two educational models. The transpiration model allows students to observe transpiration and environmental conditions simultaneously. It also avoids misconceptions between transpiration and evapotranspiration. The acid-base model allows students to visualize molecular interactions during acid-base reactions and accurately measure pH values without an experiment. Both models provide clear visualizations of processes that are difficult to observe directly.

2. UNIQUE FEATURES
Student can observe the
process of transpiration
towards root, xylem and
stomata at the same
time.
Can observe the effect
if more than one
environmental
condition occur at the
same time
Avoid the
misconception
between transpiration
and evapotranspiration
-In this model student can see the
movement of water molecule directly to
the atmosphere . At the same time they
can know how the condition in root and
xylem
Evapotranspiration= The transfer of
water vapor from vegetated land
surfaces to the atmosphere regardless of
the sources of the vapor
Transpiration= is the loss of water vapor
by plant
Compare common observation the
student can only analyze the process by
using not more than on environmental
condition at same time the taken for
obtain the data is too long.

3. ACID-BASE SOLUTION

4. UNIQUE FEATURES
Student can visualizes
how the molecule in
acids and base
solution
Student can
understand well about
the reaction occur
during the experiment
We can get accurate
data about the pH
value without
conducting the
experiment
But in common experiment they cannot
observe how the molecule structure
acids and base solution.
Easier for student to understand the
correct of Ph reading during learning this
topic and easier for teacher in explaining
the procedure to measure the Ph reading
The student can observe clearly and
determine directly which one conjugate
base and conjugate acids . Also the
ability of solution to generate electricity
