Week of Oct 25

A few things...

1. Tests will be back on Wednesday. Practice is the key to consistently solving word problems in science, so this is not the end, but the beginning :).
2. I will be out tomorrow to attend a science conference in Birmingham. A sub will be here and your assignment will be out of the book (vocab. and 19.1 review). Please check out a book if you don't finish. Assignment is due Wednesday.
3. We will be covering friction and Newton's first and second laws this week.
4. I apologize for the lack of updates on the blog during the middle of the quarter. I will be updating far more frequently moving forward.

Hope you have a great week.

Red Ribbon Week

Remember, Monday is "Be a Part of the Team" Day. Wear the attire of your favorite team...$1 for each item you wear.

More Problems

1. A rifle fires a bullet at a velocity of 645 m/s. If the bullet travels for .6 seconds, how far will it have traveled?
2. A conveyor belt that is 60 meters long is moving at a rate of 1.5 meters per second. How much time will it take the belt to complete one cycle? (click the link to see what a conveyor belt looks like)
3. A maglev train travels a total distance of 35 km from the train station to the airport. It completes this journey in 5 minutes and 25 seconds. What is its average speed during each trip?
4. A small rat runs 6 meters to escape a diving hawk. He makes it to his burrow in 2.4 seconds and just escapes. What was his velocity?
5. A Chevrolet Volt accelerates from 15 m/s to 25 m/s in 4 seconds. What was the car's rate of acceleration?
6. Cam Newton was running at 5 m/s when he had to slow down to avoid a tackler. (This is really painful, fellow 'Bama fans. BEAR with me.) He slowed down at a rate of -3 m/s/s for .7 seconds. What was his final speed?
7. A small deer was walking at 2 m/s when he was shot by a hunter. He accelerated to 8 m/s in .5 seconds. What was his initial rate of his acceleration?

HW Problems 10/18

1. A cross country runner covered a 2000 meter course at an average speed of 3 m/s. What is the total amount of time the runner spent on the course? Convert from seconds to minutes and seconds if you dare.
   
2. A volleyball player served a ball that landed 8 meters away in 1.5 seconds. What was the velocity of the ball.
   
3. At the entrance to a curve, Corvette ZR1 slowed down at a rate of -4m/s/s for 3 seconds to a final speed of 22m/s. What was his initial speed?

Think you want to do a science experiment?

One word, folks: SAFETY!

Read here for an interesting story about an experiment gone awry.

No, I haven't fallen off the face of Earth.

Hey folks. I apologize deeply for the lack of posting. I've been working double time trying to unpack in our new house as well as manage a classroom. A lot of give and take lately.

Now for some business.

1. Quarter 1 is complete. All grades are in the system. Some assignments were not visible previously despite numerous attempts to make them so. This made averages appear wonky (is that a word?). All should now be visible in INOW. I NOW would like to say something to the makers of THAT program, and no, it isn't nice. By the way, our admin has done a stellar job in keeping things up and running and none of the INow issues can be faulted to them.
2. If a blank appears next to a grade in your grade report, that means the you are exempt from that assignment, and the assignment does NOT count against you.
3. Homework assignments will now be ascribed 5 and 10 point values depending on the length of the assignment.

I am loving this school and this job more by the day. Thanks to all of YOU who make it fun and exciting. Keep up the good work.

Notes and a Balancing Equations Worksheet

Alright, the notes are posted here. A good page for balancing equations is here.

Good luck on your test.
