A1: The Aluminum vs. Wood Thermal Conductivity demonstration provides a great example of a Discrepant Event. Always hooks Ss! https://t.co/ISCfeZYA3G#scitlap

Q2: Covalent Bonding and Molecular Geometry are huge themes in Chemistry. Share your favorite activities using Molecular Models (Physical or Virtual)! #scitlap
A2: Show Ss AP Chem FRQ questions (see 1c linked below), and have them solve by making physical model. AP Qs often tunnel Ss into choosing a linear shape. This helps demystify #scitlaphttps://t.co/vl7Cqm4jd3

I 6th grade we don’t go that deep, but I like making model elements and compounds with legos. I like how it doesn’t make the kids think a bond is an actual physical thing. #scitlap
Q3: From digital probes, to online simulations, there are a myriad of great technology resources for teaching chemistry. What are your favorites? #scitlap
Me too! The demos look so much cooler? Do you use yeast or potassium iodide? (in Israel many Ss are allergic to it, so we can't use it in school) :-( #scitlap
A3 I know Phet has good PS resources, I haven't looked at any chemistry. I've also been very happy with Explore Learning Gizmos for all kinds of simulations. #scitlap

Q4: There is no arguing that chemistry can be a challenging subject for students. Which topics do you find the most difficult for students, and what strategies do you find useful for teaching them? #scitlap
A4: chemical and physical changes. It takes a while and many stations, but eventually they understand that chemical changes can happen without explosions. #scitlap
How do you encourage girls to pursue #STEM and engineering? Tell middle school kids about high school girls in engineering!
Check out this "Ladies in Engineering" hall of fame at a #MishawakaWay middle school.
GREAT way to honor these ladies AND encourage others! #ditchbook
A4: BCA for Teaching Stoichiometry! Amazing technique, solves for product and excess as well as pre-trains Ss for ICE tables in equilibrium. #scitlaphttps://t.co/mCWq07nfun
On a slightly different note, I have been looking for a good MS chemistry PBL lesson. I have yet to find something I like that is basic enough for my 6th graders. Any suggestions out there? #scitlap
A4 Conservation of Mass is tough. Experiments rarely show that mass is conserved because of errors (water droplets on the balance etc.) which leads to reinforced misconceptions and balancing equations I found is frustrating for everyone involved. #scitlap
Q5: There are lots of opportunities for doing chemistry with household equipment. What are some activities that would be perfect for parent-Ss at home collaborative experiments? #scitlap
A5 Gonna add a life sci twist here, but DNA from onions or strawberries is easily repeated at home. So is the egg/vinegar/osmosis lab I always encourage kids to do these at home and throw around some sci Vocab to impress! #scitlap
Predicting products...of course if the have a good grasp of writing formulas it becomes a matter of understanding solubility tables and activity series. #scitlap

A6: I always start with Ted Ed. Not only do they have great videos, but I like how you can make them with questions and reflections built in. The Chemistry of Cookies is one of my favorites. #scitlaphttps://t.co/j3luY0GZOm
A5: Simple battery circuit with glass of distilled water as the switch. Add salt and it closes the circuit. So, does water conduct electricity? #scitlap

I have a lab with 2L bottles and Ss gets really close to the same mass before and after if done right, but it takes good, careful experimentation. 8th grades generally are not careful creatures. #scitlap
I like @SnySciCHS Not only is is a great Chemistry teacher, but she shares her craft and thinks beyond the subject to consider what will help her kids learn better. #scitlap
Thank you so much for joining us for #scitlap tonight! Teaching chemistry is such an honor, and I hope the resources shared tonight was useful for all of you. I know it was for me!
