The NGSS calls for the use of the engineering design process in science classrooms K12. Let’s discuss what this means for the modeling classroom. Bring your ideas about how and when to integrate the engineering design process and engineering projects into your classroom. Free Webinar for all AMTA members!
Register now to attend the AACT webinar on January 25 at 7:00 EST. This webinar will introduce demonstrations you can use when they first learn the material, or as they prepare for the AP test. You'll be provided with demonstration questions that can be scaled up or down depending on the level of chemistry that you teach.
The solution to Chemical Mystery #9: Liquid Nitrogen vs. Dry Ice is presented. Why does liquid nitrogen launch the bucket so much higher than dry ice and water?
A 2L soda pop bottle is filled about one-third full with either liquid nitrogen or solid carbon dioxide (dry ice) and water. The bottle is sealed and a plastic bucket is placed on top. Do you think the liquid nitrogen or dry ice and water will make the bucket go higher? Can you explain the results using chemistry?
The January 2017 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: NMR spectroscopy; examining assessment; inquiry-based practices; cost-effective instrumentation; miscibility demonstrations; innovative laboratory experiments; from the archives: lightsticks.
The untold story of the women who helped win World War II by separating the atomic bomb isotopes.
This is the first isotope activity I have tried where the students can look inside the model that resembled the atom and find information that reinforced what an isotope actually is. Furthermore, the quantitative data forced them to examine beliefs about different types of averages and what the numbers really mean.
You probably know what happens when you place dry ice in water. Do you know what happens when dry ice is placed in acetone or glycerin? Read this and find out!
Last month, I shared about a new PD opportunity I had the privilege of participating in called Gizmos. You can read about it here. After Thanksgiving break, my Chemistry 1 and Honors Chemistry 1 classes began our Chemical Reactions unit.
I have used several different versions of the Silver Mirror or Tollen's Test lab. I am sharing the method that has proven to be the most reliable for me. The solutions should be made fresh, the directions must be followed closely and timing is very important. I like the fact that relatively small amounts of the chemicals are required, but as always you must be vigilant with safety precautions.
