STEM students enlighten their knowledge of buoyancy while designing, building, testing and flying a hot air balloon.

[Fred Fotsch @FredFotsch]

Hour of Code in the classroom using TI Nspire student edition. Student writes clever "Leaf Leap" game program. Fun!

[Fred Fotsch @FredFotsch]

Students write code to hijack magnetometer of iPad to measure solenoid magnetic field vs current. CX analyzes data.

[Fred Fotsch @FredFotsch]

STEM students build solenoid actuator for doorbell. Press button and nail jumps! One student said "this is magic".

Combustion reaction demo in AP chemistry class. Powdered carbohydrate explosion.

[Fred Fotsch @FredFotsch]

Replacement reaction demo for AP chemistry class. CO2(s) + Mg(s) -> C(s) + MgO(s) and lots of fog, light and sparks!

Remember the M in STEM? Perhaps it's for data Modeling? Sign up for Science Nspired PD webinar http://t.co/rxnWaGQ1RR

[Fred Fotsch @FredFotsch]

At ~22/7 class at Central Market. This is a STEM project that you can eat!

[Fred Fotsch @FredFotsch]

Learning about the great curriculum available free on the TI Science Nspired web site at the 2014 CAST conference.

[Fred Fotsch @FredFotsch]

Chaos in the classroom! Students LUA a nonlinear dynamical system. Xn+1=r*Xn*(1-Xn) iterated 200 times for each r.

[Fred Fotsch @FredFotsch]

AP chemistry students investigate Boyle's law and model data using Nspire CX, pressure sensor and Nspire Navigator.

[Fred Fotsch @FredFotsch]

Soda water maker, Go Wireless Temp, Nspire for iPad used for demo of 1st law of thermodynamics from expansion of CO2

[Fred Fotsch @FredFotsch]

STEM students use laser cutter and ferric chloride to make PCB and 3D printer for case to build conductivity tester.

[Fred Fotsch @FredFotsch]

@davidallenyoung Great idea! Though we might include Luke :)

[Fred Fotsch @FredFotsch]

STEM students study Monte Carlo approximation of Pi algorithm and write the program in LUA on Nspire student edition.

[Fred Fotsch @FredFotsch]

Students learn to program iPad with LUA using TI Nspire student edition in my STEM class. Pics of quick sort program.

[Fred Fotsch @FredFotsch]

Students using Nspire handhelds and pH probe to find percent K+ in sample. First derivative plot used to find end pt.
