Collisions

We are exploring some collisions today.

Momentum Lab

Doing a quick momentum lab. Mass times velocity. We are using video physics from Vernier.

Newton's 2nd Law

We are using Modified Atwood to prove Newton's 2nd Law.

Weight vs. Mass

We are trying to discover the relationship between mass and weight.

It's close.

The only way to test

Today we are a having an evaluation of our knowledge in kinematics, or lack thereof. I like the use of the whiteboards .

Happy Halloween

Happy Halloween

PhET Vectoring

Today we are PhET vectoring trying to get the hang of vectors and how to draw them. We are previewing free body diagrams as well. 

Practicing Acceleration

We are practicing making velocity graphs and then calculating acceleration. We are also calculating displacement from the graph and by formula  

The Moving Man

The moving man? The moving man! The one in physics!
One of my favorites. After doing the graph matching lab, doing the moving man really solidifies the idea that motion graphs mean something. 

College Shirt Day

Still working Graph Matching. It's college shirt day, not sure what it has to do with a big top theme.

More Graph Matching and Class Shirt Day

America Day and Graph Matching

Today is the first day of homecoming week and we are doing a graph matching lab with the lab quests, ipads, and motion detectors. Today's theme was America Day 

Hitting the Brick Wall

Today, we are trying to use graphs to describe motion. They have to which graph is correct and which are wrong and why they are wrong. 

UGC in style

• 

65 inches of style. It's too bad the UGC isn't in HD. It beats doing it on a laptop.

Ultimate Graphing Challenge

I love this game. It's a great intro to interpreting d. vs t. graphs and v. vs t. graphs.   

The Last Few Days

The last few days we have been constructing cars and using algebra to predict when the cars will tie in a race. We use Video Physics and Graphical to figure out the speed of the cars. Then we use Ubersense to record the finish in slow motion. 

Vroom Vroom

It's car building day. It might be the first time some students have soldered .

Lights, Camera, Buggies

We are learning how to use Video Physics and Graphical as well as exploring constant velocity graphs. 

I need to stop slacking with our blog

I apologize about the lack of posts for this new school year. We are playing with Hot Wheels to figure out what effects the speed of the car. We are also getting used to using the iPads. Our favorite apps are: Schoology, Notability, Video Physics, and Graphical. 

Notice our use of the textbooks. They are best used to prop up ramps and stop cars. 

Hf and Hv

We are trying to calculate heat of fusion and heat of vaporiation of water today. As one student put it, that's why it takes forever to make my mac and cheese. 

Specific heat lab

We are doing a specific heat of metals lab. 

Speed of Sounds/wavelength of our voice

We are calculating the speed of sound here in Evergreen two different ways. We are also calculating the wavelength of our voice saying ahhhhhhh. 

Starting to talk about reflection

Reflection and reflection lab. 

Musical Instruments

Students have been creating and tuning their own instruments. We have a pretty good guitar player that made a dulcimer.

Life Can Get Back to Normal Now

For the past month, I have been all consumed by the Samsung Solve for Tomorrow Contest. In the past 2 weeks we have created an electric go-kart and video for this contest. Here is our product. Hopefully, we will win but I can now rest easier. Thanks to the students who helped me out and the support of the staff at EHS. 

Thermo Projects

The project is to answer one of the following questions: 

1. Which travel mugs should you get to keep your coffee or tea the warmest on your journey to school? You may not use my calorimeters!

2. What should you keep your soda in to keep it the coldest at lunch time?

3. What enclosure keeps the pizza the warmest? Aluminum foil, cardboard box, paper bag, saran wrap?

4. Is a down jacket really warmer? 

5. Does the shiny side of aluminum foil matter in keeping your burrito warm?

6. Are mittens really warmer than gloves?

This was my favorite. A tad light on the science but it's the creativity I have been craving. 

Our results were the following:

Most boring lab ever

We are make the temperature vs time curve for water in hopes discovering the idea of heat of fusion and heat of vaporization.  The interesting part is the hypotheses of what the graph should look like. Most pick linear or exponential. I like it when it's not either.
