Topics
measure to obtain a reading from a suitable measuring instrument
Skills Engaging with an event, phenomenon or problem through:
Collecting and presenting evidence through:
Observing This is the skill of using our senses to gather information about objects or events. This also includes the use of instruments to extend the range of our senses.
Using apparatus and equipment This is the skill of knowing the functions and limitations of various apparatus, and developing the ability to select and handle them appropriately for various tasks.

Introduction
Play with the Mass Scale Model. Test what you've learned by trying the input field.
This Mass Scale Model allows the skills of reading from a circular scale of a typical weighing scale. The three options available allows for student's own testing of the different scales with different decimal places of precision appropriate in each scale's smallest division.

Common misconceptions
Students typically can tell masses of whole numbers such as 600 g, but to be able to type in 0.60 kg requires some understanding of decimal places.

New Feature Added
Now, grams option is added for ease of whole number learning


Sample Learning Goals
(g) describe how to measure a variety of masses with appropriate accuracy by means of weighing scales.

Interesting Fact
This simulation has touch-sensitive controls for the pointer and the actual reading (yes, I need to program for these features) which other apps may not have.

Acknowledgment
My sincere gratitude for the tireless contributions of Francisco Esquembre, Fu-Kwun Hwang, Wolfgang Christian, Félix Jesús Garcia Clemente, Anne Cox, Andrew Duffy, Todd Timberlake and many more in the Open Source Physics community.

Kinematics Non-linear motion
Description
Play with the 2 Cannon pointing at each model. This simulation can be used to illustrate the thought experiment "The Monkey and the Hunter" often used to illustrate the effect of gravity on projectile motion.
The Monkey and the Hunter Experiment
A hunter with an arrow goes out in the woods to hunt for monkeys and sees one hanging in a tree. The monkey, we suppose, releases its grip the instant the hunter fires his arrow. Where should the hunter aim and when should he fire in order to hit the monkey?

Answer :
It is conceptually in the green line being without the effects of gravity, the cannons ball will meet as predicted by Newton's 1st Law of motion without net external force. now, adding the same gravitational acceleration means both cannon balls will move down at the same rate ( pink lines). therefore, the 2 cannon balls has to collide .

Sample Learning Goals
(g) solve problems using equations which represent uniformly accelerated motion in a straight line, including the motion of bodies falling in a uniform gravitational field without air resistance


Interesting Fact
3 different scenario are added, involving the same idea of newton's first law in the absence of gravity, resulting on collision after being acted on by the same acceleration.
