STEM Pre-Academy

Welcome to the STEM Pre-Academy!

The STEM Pre-Academy fosters inspiration and relevance in Science, Technology, Engineering and Mathematics primarily through initiatives, such as teacher workshops, technical focus sessions, and collaborative interaction between middle school teachers and subject matter experts. This teacher-driven multidisciplinary program helps middle school public educators develop and implement research and technology based student curriculum including lessons, activities and projects.

The STEM Pre-Academy is a state-funded program, focused on public middle school teachers in Hawaii.

Feature Project: iPad Enabled Digital Publishing @ Moanalua Middle School

At Moanalua Middle School, Language Arts teacher Kathy Nagaji and her team piloted a project with students entitled, “iPad Enabled Digital Publishing”. They drew inspiration from the October 2013 iPad workshop co-presented by STEM Pre-Academy, Hawaii Creative Media, and students from Searider Productions, Wai`anae High School. Kathy and her team successfully sparked students to write in various genres by providing them an opportunity to create relevant, high level products and share them with a wider audience of their peers. The curriculum developed and implemented boosted student engagement and motivation to all-time heights.


Follow-up Mini Workshop: Water Quality Field Trip to Kualoa Ranch

On Saturday, July 26, 2014, teachers from Waipahu Intermediate, Aliamanu Intermediate, Moanalua Middle and Ewa Makai Middle schools met at Kualoa Ranch Educational Center to participate in the STEM Pre-Academy Water Quality Follow-Up Mini Workshop.

Edwin Colon gave an "Introduction to Water Quality" presentation to go over the technical aspects of the water quality parameters teachers tested that day. Dr. Marek Kirs, a researcher at the University of Hawaii Water Resources Research Center, shared his research data and insight on water quality in the streams and beaches in Hawaii.

After the presentations, teachers headed out to the stream to to see how a field trip like this could benefit their students, and how they might incorporate it this upcoming school year.

ALoha Edwin - I am setting up my design challenge now:

In partnership with Manalulu Farms, Mars Fut-R-Flight program has created a design challenge for all of you rocket enthusiasts. We are calling it the Payload Orbiter Challenge. The challenge is to create a rocket that will launch a quail egg (payload) to a geostationary orbit (___feet) and land the quail egg safely back to Earth.


The constraint will be the minimum and maximum height. The closest launch to the maximum height will score more points. I will also be making a list of the prices that go with each part so the students have to take cost into consideration. Here is where I could use some help from an engineer.


I have estimated that the rockets will weigh between 50g and 100g with the egg, altimeter, and engines. The students will get to choose their engines. I need to find out what the minimum and maximum height should be set to. Our rockets weighted between 50 - 85g and went between 50 - 174feet using an Estes A8-3 engine. The students will be able to choose their own engines. I need to find out:

1. What the minimum and maximum altitude should be set at?

2. It looks like if the students stick to 18mm engines, they can changes sizes when they IMPROVE their prototype. It looks like A through C is 18mm. Should I limit any of these motors?


Mahalo for your help!

Aloha @pyerxa :

Launching a quail egg is a cool idea. I would not recommend launching rockets higher than 250 - 300 ft. I know you like to go BIG! but remember to stay safe. If the student use heavy rockets (meaning 90-120 g total) you can use engines from the A8-3 to the C6-5 (and even with this restrictions, C engines might be too powerful). I would not recommend anything higher that those engines. I did a quick research and found out the weight of this eggs is an average of 13 grams (not bad). Adding the egg alone might not be enough weigh to keep the rockets from going too high. It might be a good idea to restrict the use of engines based on weight of the rocket. Let me know if this answer your questions or if you need more help.


I found this rocket looking for information to answer your questions. There is something really interesting about the configuration of this specific rocket... (hint: the egg goes in the nose)

Mahalo Edwin. I am planning to do my next unit on sustainability. I want my students to possibly make their own motor to measure voltage of windmills, solar panels, etc. Do you suggest a company that puts out good stuffs like this so that I don't go look all over the Earth first? I know you have made a motor with a kid using a battery. I want them to make one that they can plug into a volt meter. BTW - is it possible to run the motor both ways. Wind to voltmeter and Battery to fan?

Aloha @pyerxa! Wow, if I understood what you said, sounds like you are mixing a few projects in one. You have an electric motor, a windmill, solar panels and a performance test using a fan and volt-meter. What is your expectation from this project? I can suggest some of our Open AIRE kits or point you in the right direction, but need to clarify what do you have in mind and what you want to accomplish with this.

Weather station at #JarrettMiddle is up and running!!! The #weatherstation will be used to provide actual weather data to improve the predictions from RockSim (Rocket Modeling Software). Thanks @pyerxa for trusting us with the installation and set up of your system!

Aloha Edwin - Mahalo for setting up my weather system! I had a small problem when I was registering it. I was registering it at home and it asked for my MAC Address. Found that and put it in. It then told me either I typed it in incorrectly or the bridge is not available. Is this because I am not on the wireless that the Acurite is riding on? I am guessing that the bridge address is the one at school. Here's the link:

Paige, I think you have to provide the MAC Address linked to the weather station bridge. Meaning the MAC address of your classroom network. @sbrown

Hi Paige!


The MAC address you want to use for the registration is the one on the back of the bridge. Pages 7-11 of this PDF have some pictures of this. http://www.acurite.com/media/manuals/acu-link-instructions.pdf


Let us know how it goes!

Aloha @pyerxa,


Were you able to register your weather station? Let me know if you need our help. I'm looking forward to see your weather station implementation!!!
