Making Frushi at Family Cooking Club

Last night we had another successful Family Cooking Club! This time the kids made their own fruit sushi (aka Frushi)!

The results were delicious!!

From Hackbright Academy:

Here are 6 things you can do right now to help your children become more resilient as future innovators and leaders.

April Workshop - Tilting Bird

Scjence Blog Steam Banner

The focus of our workshop this month was the tilt sensor, also know as an accelerometer. We talked about how accelerometers use gravity to determine a change in orientation. Older smartphones used accelerometers to automatically change the orientation of the screen, depending on how it was held. The Nintendo Wii remote also uses this same technology for game control. 

Newer phones, like the iPhone 5 and 6, use gyroscopes--or more specifically, MEMS (Microelectromechanical systems) gyroscopes. These tiny gyroscopes (.02mm-1mm) are manufactured using a chemical etching process. I also demonstrated a classic mechanical gyroscope, showing how it balances on a string and how it resists a change in orientation.

We wrapped up the lecture part of the workshop with a short video showing how the inner ear helps us keep our own balance through three semicircular tubes filled with liquid.

The actual LEGO building part involved a model of a bird that made different noises when it was tilted. The sounds were triggered by a LEGO tilt sensor connected to the laptop.

March Workshop - Hungry Alligator

This month, we talked about motion sensors--how they work and how they're used. We also discussed infrared wavelengths and where they fall on the electromagnetic spectrum, how polarizing lens are used to filter out glare, and how bats use echolocation for navigation.

All this background information led to this month's project, which was an aliigator with a moving jaw that was triggered by a motion sensor.
