Synopsis: This video give a nice and short explanation of Newton's third law, followed by multiple examples of this law.

Duration: 23:16

Synopsis: This video, through a number of various examples, looks at Newton's three laws of motion, while revisiting some of the key ideas behind the various laws of motion to really help student to understand these three laws.

Synopsis: As an example of students placing the idea of stretching into something that each of them can do, this video not only looks at the types of stretches that specifically benefit the focal athlete of this video, but also discusses different athletes in different sports seek flexibility in different parts of the body.

Duration: 9:47

Synopsis: This video does go through a lot of content in just under ten minutes, but what is great about the contents of this video is that they cover almost all of the knowledge outcomes that support the first understanding in this unit; this video would be great to introduce the unit, or to review many of the ideas at the end. The other notable side to this video is that it really does give a good background on not only Newton, but shows the profiles of a few other key scientists when it comes to motion and forces.

Duration: 3:07

Synopsis: This video does give a really good example of Newton's third law, but it also give somewhat of a bad example. In the first part of the video, the astronaut throws a ball, and questions if he is moving backwards. What is key here, is to mention to your students that it did cause him to begin moving, arguably as a slow rotation. What is great to see is that when he pushes something of roughly the same mass (another astronaut), that he moves backwards in the opposite direction.

Synopsis: Not only is this video nice and short, it does a great job really giving examples of Newton's three laws of motion in the context of riding a bicycle. Even though students in grade three really don't need to understand a formula like F=ma, this video does a good job of just briefly mentioning it as Newton's second law, and then giving context of it when riding a bicycle.

Duration: 3:17

Synopsis: While there are multitudes of examples of forces that are pushing and pulling in these videos, there are not as many videos that really look at what squeezing (compression) and stretching (tension) scientifically are. This is a great video for you to integrate with the Scientific Methods within Science 3, as you can ask your students--what do you think will happen when a wet washcloth is wrung out in space?

Duration: 6:48

Synopsis: This video looks specifically at Newton's first law, and places emphasis on the viewer learning the word "inertia." The video introduces students to Newton's First Law of Motion, and then gives repeated examples of why this law always holds true.

Duration: 22:46

Synopsis: The curriculum requires that we look at levers, wheels, and inclined planes; while this video certainly covers those three, it also looks at some of the other simple machines.

Duration: 2:01

Synopsis: While thousands of Rube Goldberg devices created and recorded can be found around the internet, almost all of them are made of an eclectic collection of materials. What makes this video really unique is that all of this Rube Goldberg device is built entirely of the parts of a specific model of a car. (Be sure to note to students the importance that this car has a windshiled that can detect rain.)

Duration: 3:18

Synopsis: This video starts out by reviewing a few of the other simple machines, and then delves into an explanation as two what a wheel and axle are, and why they are classified as a simple machine. 

Duration: 3:38

Synopsis: This music video certainly celebrates all of the many ways that simple machines can be combined to create fascinating systems. All of this is doen while their song is sung.

Note: There is one use of "hell" in this song near the beginning; that aside, the lyrics are clean.

Duration: 4:08

Synopsis: What better example for kids to need a ramp, than to have boxes full of books that need a ramp? This allows for the promotion of literacy while looking at a simple machine! One of the key pieces in this video is that the hostess places emphasis on the idea that a simple machine is anything that "helps us do work." Though the video is titled "Ramps," she does not use the term "inclined plane" in the video; it would help if your students understand that they are the same simple machine.

Duration: 1:30

Synopsis: Though a relatively short video, what is really great about this video is the fact that the narrator continues to reiterate that ramps and inclined planes are synonyms. This video might be worth playing just to ensure that students understand that these are the same thing.

Duration: 3:19

Synopsis: This video takes a look specifically at the simple machine of levers, making sure to place some emphasis on the key word "fulcrum." Though it is my own personal critique, this video does use the enunciation of "lever" that some regions prefer--the one that rhymes with clever (I prefer the enunciation that rhymes with "fever.")

Duration: 5:41

Synopsis: This video runs through all of the simple machines, and one of the nice additions in this video is that it includes some of the history behind the use of simple machines, and mentions key scientists in history such as Archimedes (even though the video claims he was more recognized as a philosopher than as a scientist--I would beg to differ.)
