5 Newton's 3rd Law Tutorial
This tutorial was a little more difficult than the previous two. The questions were also more challenging. The balloon rocket activity is an easy and accessible hands-on way to demonstrate force in the classroom. For every action there is an equal and opposite reaction can be related to students using simple class objects; such as, desks and chairs. The PISA marble activity would be another way to demonstrate the Third Law in the classroom. Atoms and electromagnetic forces act like springs and push back on you. This tutorial was very helpful in understanding motion.

5 Newton's 2nd Law Tutorial
Fascinating! This tutorial was absorbing. The video demonstrations were so helpful in understanding Newton's 2nd Law of force, mass and acceleration. When a state of rest or motion changes, it must be due to the action of a net external force. The JetToy activity learned at PISA would be an excellent way to demonstrate this principle in the classroom.

5 Newton's 1st Law Tutorial
This tutorial on Newton's First Law was very informative and interesting. The activities shown made it easy to relate to real life using prior knowledge. These activities would be easy to facilitate in the classroom as well. The hands-on activities would help students to understand that an object at rest tends to remain at rest unless acted on by an unbalanced force. Very enjoyable and relevant to our lessons at PISA!
