Waves- Japanese Wave Pool

 
This is great! I saw this video on Outrageous Acts of Science on the Science Channel. A common misconception about waves is that the water moves with the wave, when in fact the wave is the energy moving through the water. This video is a great example of this principle.
Daily question: Why don't all of the people in this video get washed out of the pool in the first wave?

Makey Makey

This is a little off the normal posts, but I recently bought a Makey Makey. What a great product! We (the 8th grade science dept) are hoping to have a few in our class next year. These are amazing. What is a makey makey? Check out the video How to Hack a Banana. Go ahead I promise it is worth it!


http://popularscienceteacher.blogspot.com/2013/05/ted-hack-banana.html








Cool right? Here is a video of my own kids about five minutes after we got it out of the box!

It is so easy to use. They are a little intense. They really loved it. You can hook it up to almost anything, it just has to be a little conductive. The makey makey how to site was a big help.

I love how they decided the 4 year old should be a note.



Here is a link to MakeyMakey, I will update as soon as I have tried it out in my class! We ordered 8 which should be enough for 3-4 per group. I think I am going to give them a theme and see what happens. Can't wait!

What? A cockroach dissection? Sound Waves? Electric signals?



This is great!
He actually dissects a cockroach on stage, hooks it up to a speaker and makes it move based on the electric signal produced by the sound. Lots of good possible daily questions. Since I am focused on sound right now I am basing it on that. Daily Question: What type of speaker produces a low frequency sound? Draw a picture of what that wave might look like.

Electricity Vocabulary




This video is really interesting. It looks at the history of the vocabulary we use when we talk about electricity.

What a cool (pun intended) lesson plan on the difference between weather and climate! It even involves chocolate!

Hot Wheels Real life 2012 X Games




Inertia anyone? Friction? Gravity? There are several opportunities to work this one in.


Daily Question: Did you play with hotwheels when you were little? Or now? How does this work?

Seasons

Well, I don't teach the seasons in Physical Science but since I do have to review 6th grade science for our SOL, I couldn't resist this video. I found this on Pintrest. If you aren't pinning yet, you don't know what you are missing!





Daily question: What causes the seasons to occur here on Earth? What is your favorite season and why?

Dark Lightning (Electromagnetic Spectrum)




Dark Lightning! How cool is this. Be prepared for some serious conversations about radiation exposure.
I first thought this would go along with lightning and electricity, but I think it fits better in my Electromagnetic Spectrum unit. Nice clip of the Hulk doing his thing.

Newton's cradle Mythbusters



Newtons cradle
If you have the time to show this whole episode to your students. I think it is worth it, except for the chicken on the car myth. I like the way they size up the models.

Daily question- what are Newtons three laws?

Relative Motion Ballerina and Volvo truck comercial




This is the craziest video!! This was on the NSTA website. Here is their summary of it-

This is an advertisement for a brand of truck, but it is also an excellent way to introduce relative motion. The two trucks, the rope, and the high-liner are all moving relative to the ground, but not moving relative to each other. To fully describe motion, it is essential clearly state your "frame of reference" so that others will know what "zero velocity" actually means.

Daily Question- What is relative motion?  What is her velocity relative to the ground? Relative to the truck? Relative the the wire?

TED organization of the periodic table

If you are not familiar with TED you must check this out. TED is a collection of short lectures from some of the greatest minds of today. In their words, "Riveting talks by remarkable people, free to the world". The following link will take you to TED Ed which covers several subjects.

http://ed.ted.com/lessons


This video gives a nice history of the early theories of the elements and the periodic table.

 
Daily Questions: Who organized the periodic table in the format we use today?

Gotta love science.
Daily Question- Who are these guys? How does what they are saying help you figure it out?

Kinetic/ Potential Energy Wiley Coyote style

This video shows the usual encounter between Wiley Coyotoe and the Roadrunner but includes kinetic and potential energy  labels. I haven't tried it yet, but I would like to have students make their own videos and caption it with kinetic and potential energy. Let me know if you have tried something like this, I would love to know what software/app you used.


 
Daily Question: What is kinetic energy? Potential energy?

Pressure/Friction/Melting point Ice Skating Mystery

Great for a lesson on density and buoyancy.
Daily Question:
How come the manatee which weighs 440-1200lbs manage to look so graceful underwater

Physics and the NHL

This is a great resource from NBC. All of these videos are extremely high quality and well done. The subjects vary and include kinematics, velocity, density and friction. I am going to included a couple of my favorite videos with daily questions, but I highly recommend this whole site. It is worth taking a closer look at.

https://www.nbclearn.com/portal/site/learn/science-of-nhl-hockey

Acid versus Base

This one demonstrate how destructive strong bases and strong acids can be.
Daily question: What is the ph of an acid? A base? What is the ph of a weak acid and a weak base?

Periodic table video coke cans ( There is a mistake on this video- or at least a confusing camera angle where the Base and Acid are mixed)

Parkour and friction

The students love these videos. Parkour is a popular form of urban sport where a person must get from one point to another in a creative and fast manner. Whenever I show the Parkour video I also show the fails video. The professionals make it look so easy, the fails bring kids back to reality and I think it is less likely for students to Parkour down the hallways and stairs. The music is very hip hop and may not be appropriate for everyone, you may want to mute it. As always with You Tube, you need to check the area around the video for inappropriate ads.

Daily question: What are the four types of friction? What type of friction do the runners use to stay on the walls or bars? During the fails video what the of friction is causing the injuries?


http://www.youtube.com/watch?v=NX7QNWEGcNI&feature=youtube_gdata_player

Fails video

Decomposition Chemical Changes

Time release video of a hamburger decomposing. If the hamburger is too gross, another option is the fruit. The different types of hamburgers does stir up a lively conversation.

Daily question-

What type of change is occurring? Physical or chemical? How do you know?


http://www.youtube.com/watch?v=8uHxRwQqWFo&feature=youtube_gdata_player

Air pressure and change of state

I like a lot of the Steve Spangler videos, but this has to be my all time favorite. It takes the can crushing demo to a whole new level. He crushes 55 gallon drums! It has the can demo at the beginning so show this after any in class demo. You don't want him stealing your thunder.  This video is 14 minutes long. I think it is worth the class time, but if you want a shorted clip the link to a 2 minute video is below.

Daily Question:

Draw a picture of the forces acting on this can. Draw a picture of the molecules in the can before the warm water and after.

 
 
Two minute clip

This one is the clip from the movie Twister where the cow is circling the truck in the tornado. The faster the fluid flows-the lower the pressure goes.

Daily question: What is happening to the cow and why?

Air Resistance- Transformers 3

This is one of my favorite clips. It is a behind the scean look at the Squirel Suit or Wing Suit jumpers, jumping off the Sears Tower in Chicago. This is a great clip for gravity, air resistance or fluid friction.


Daily Question: Draw one of the jumpers  and label the forces. Include the words, gravity, air resistance, fluid friction and awesome.

Buoyancy the Dead Sea

This clip is 6 minutes long and demonstrates a 14 lb bowling ball floating in the Dead Sea.
Daily Question: Draw a picture of the bowling ball in the Dead sea. Label the forces acting on the ball.


Buoyancy Killer Quicksand

This is a nice clip for buoyancy. It is only a few minutes long and summarizes the whole experiment.
Jamie and Adam test the movie image of killer quicksand. The kind that sucks you under.

Daily Question:
Why didn't Jamie sink in the quicksand? Why is his buoyancy different in quicksand vs. water?

Bernoulli's Principle

This is a clip from Finding Nemo. It is the scene where Marlin (Nemo's father) wakes up on the shell of Crush the sea turtle cruisn' the EAC. (East Australian Current)

This is a great video for Bernoulli's Principle. The faster the fluid flows, the lower the pressure goes.
http://www.movieweb.com/movie/finding-nemo/the-eac

Daily Question:
What is the EAC? How does it relate to Bernoulli's Principle?
