Last year, I researched and practiced what I thought to be "flipping the classroom". But, now that I am taking part in a district-wide "High School Blended Learning Pilot", I can say that I was attempting blended learning early in my teaching career. You see, the flipped classroom is really a small subtype of blended learning. So, the goal of this post is to define blended learning and share what my professional development has in store for me during this academic year.
A description of a quick and easy lesson that is sure to add some spark into your next lesson on stoichiometry.
Late last school year at a staff meeting, teachers were informed that we were going to be coached and encouraged to introduce more vocabulary instruction to
You can perform an orange to black chemistry demonstration using materials commonly found in stores. The reaction appears to be similar to the Old Nassau reaction, but uses greener reagents. This is a great demonstration to do around Halloween time.
Common drain cleaners consist of water, sodium hypochlorite (bleach) and sodium hydroxide (base) and/or potassium hydroxide (base). Bases are caustic (caustic loosely means to gnaw or eat away at) and can cause corrosion in metal pipes. Wouldn’t you know, our house has PVC piping through the fixtures that dump into a 45 year old cast iron pipe. The cast iron pipe is old and currently shows signs of surface rust and corrosion to the point where the pipe appears to be leaking then sealing itself in several spots. Not to mention the interior of the cast iron pipe may not be completely open, thus, not permitting a fast flow in drainage. Good news: a home warranty is being taken advantage of to hopefully replace the cast iron pipe with a PVC pipe.
A few years ago, we launched a weather balloon during our summer science camp. The balloon reached an altitude of 30 km (100,000 ft)! Among other things, this project ended up being a great way to teach campers about the gas laws and how atmospheric pressure decreases with altitude.
How does the blue to white color change occur in the foam of Scrubbing Bubbles or KABOOM Brand cleaners? Watch this video and find out.
Build a propane gun for your students! Construction is inexpensive, easy, and the effects are spectacular.
The video displays a neat trick you can do for your students. What do you suppose is the secret behind this trick? Hint: >It has to do with chemistry!
