"If One is Good, Twenty Four Is Way Better!!"
leyrerwa
As a teacher of Electronics and Aerospace Technologies at a Technology Center I am always looking for exciting ways to get my students involved in activities that will challenge them but, at the same time provide them with a rewarding sense of accomplishment, increased self esteem and most importantly an opportunity to have some fun while learning. I have found few project oriented methods that perfectly fit that description better than model rocketry!! They say that it is always better to buy in bulk! Well speaking from experience, especially through Hobbylinc, that truly is the way to go! With a class load of 25 to 30 students, it doesn't take long at all to go through many, many rocket engines in a very short time frame. I'm not talking about any waisted engines either. The students simply get so excited about building and flying their rockets, they can't fly them enough. As an instructor, there is nothing worse, in my opinion, than having a group of students get really excited about a project like model rockets and then be forced to stifle that enthusiasm by having to tell them, sorry, we're out of rocket motors!! The bottom line is , Bulk Up!! With limited educational funds, buying in bulk is the most cost efficient way to insure you'll have all the materials you'll need for your students, scouts or youth group when their needed and to keep the fun rolling!! Bulk Educator Engine Packs are available in a wide variety of Impules and delay charges as well as including recovery wadding, igniters and plugs. Don't be caught short on the flight line! Clear Skies!

This works well on semi windy days. This makes it so it doesn't go to high and get caught in a cross wind.

 
"Great Class Ending Project"

I teach Physical Science to 8th graders and we always end the year building, decorating and launching these rockets and engines as a celebration of all physical science has helped us achieve. The students love it, other grades come and watch launch day on the football field. Even the elementary students and teachers come over to watch the countdowns and get excited about science. It's a great way to end 8th grade and send them on to the high school.
