4 Position and motion
The tutorial has many self-checking questions and interactive video clips. I did enjoy the hare and tortoise video clip because it’s a story many students have heard and know that the tortoise wins the race because he had a steady pace throughout the race. The hands-on activity about rolling a ball across a smooth surface is an activity I will conduct in my classroom. I learned that when you specify the velocity of an object you must specify not only the speed but on which direction it is traveling.

4 3rd law
The video clips for Newton’s 3rd law are very helpful in understanding exerted forces; especially video clip “Action and Reaction”. The self-checking questions are useful throughout the reading to make sure you have a clear understanding of the law. This resource also has a glossary page with vocabulary words that are used for the explanation of Newton’s third Law.

5 Newton's 1st law
The tutorial was very informative; it was surprising that Galileo had the idea of the first law before Newton. The law was broken up into small pieces which were easier to understand and to explain to our students. The interactive activities were easy enough to demonstrate in the classroom. The 1st hands-on activity was demonstrated in my classroom in the beginning of the school year as a warm up.
