We have a few days left to build these bridges. Just a few more bridges have yet to be completed. Lunch time building seasons are your if you want them. The choice is yours. Make your time count.

Applied Technology 7

We are going to continue to do building in class for the rockets.

Here are the specs for the Cheetah Mk II rocket launch on Monday – that crumpled from the sheer speed and pressure differentials. Top speed 1292.4 km/h. It was extremely brief brush with the speed of sound, but we did officially break this barrier, technically still transonic. In order to achieve supersonic speed, this rocket would have to have a peak flight speed at 1468.8 km/h or Mach 1.2

The Jolly Logic altimeter confirms this speed. Our peak altitude was pinned at 1.15 km.

Here is a picture of the new AeroTech blue thunder propellent on the Lil’Nuke putting an impressive display on the rail. This was a subsonic launch and the rocket travelled 1.25 km in altitude and drifted quite a distance from the launch pad.

Science 7

We are continuing to look at growing crystals. Some solutions need a bit more work. We also need to get a good look at Chrome Alum, Copper Sulphate and Cobalt Sulphate under the microscope. Borax will look really interesting as well!

Draw the crystal structure out as you see it. Discuss the time it took to grow the seed crystals in the bags. How long it might take to grow a crystal that is X centimetres (cm) larger? This is all part of the lab process.

Here is document used in class today that is in-class work. Follow the link here: crystal-structures

For those students wanting to remake the crystal growing solution, here is your solubility specs:

  • Cobalt Sulphate – 84 g/100mL (water @ 100C)
  • Copper Sulphate – 80 g/100mL (water @ 100C)
  • Chromium Potassium Sulphate – 24g/100mL (water @ 100C)

We are continuing with online evaluations in the shop. I so far have a handful of students who have finished these evaluations so far. Many students have yet to fill this form out!

Applied Technology 6-2

Second to last full day for the bridge construction. Let’s make it count! We’ll be moving on to the cutting boards by next week.


Update: Science 7

Seed crystals are currently growing. Here are a few images of the Copper Sulphate, Chrome Alum and Cobalt Sulphate crystals growing.

Applied Technology 7

Hopefully, the weather will hold off for our rocket launch today. I really hope we get a chance to make some history and achieve supersonic flight. Using our GPS enabled Jolly Logic III altimeter, we’ll see how fast the rocket will go with the right motor!

Remember – we are launching 4 large rockets!

If the weather isn’t good for a launch, then we’ll continue with building our rockets.
