Aloha Edwin - just send you an email about the solar panel boats and the flex shaft kits. Kinda got a little pricey with ordering 10 and then 10 replacement kits. Kits also include the dry dog. My email just simply asked what is the minimum I should order if I need enough for 5 solar panel boat groups?

Hi Edwin,
Hi Edwin. Tomo would like to know if you have available a freeze dryer to use for a science project. It deals with making a mold from the extracts of agar, then extracting the water from the mold, leaving behind a prototype model to test as a fire retardant. If one is not available, do you know anyone that may let us use it for a science project?

STEM Pre-Academy don't have a freeze dryer in the inventory. I will ask some of our researcher to see if they have one and are willing to help.

Aloha! I'm a new 6th Grade Math and Science teacher on Lana'i. I am interested in your lending library and am wondering if you have a periodic table, conductivity testers, pH and temperature probes (for iPads). --Kapua (Michele) Weinhouse

Welcome to STEM Pre-Academy. The program don't have periodic tables in the inventory but do have an advance water quality sensor capable of measuring pH, Dissolved Oxygen, Conductivity, Salinity and Temperature in liquids. This is the link for this sensor: The sensor connects via bluetooth using an Airlink2 to iPads or Chromebooks using the Sparkvue app. The app is free to download.

Please, Let me know if this is what you are looking for to help you through the request process.

Mahalo Edwin. The drive dog link takes me straight there to the specific part. However, the Prop & Prop drive shaft just takes me to the prop options. Is there any way you can help me choose exact props & prop drive shafts (like the drive dog link)? There is too much here for me to understand and sort through. I'm a bit confused. Mahalo

Aloha Edwin,
My students are interested in learning about Wave technology as a source of harnessing energy. For the Science Fair, the students will need to come up with a problem and solve the problem. I am wondering if you have any suggestions for what specifically we might explore?
