Which threshold did your students find most challenging, and what strategies helped make it more accessible?

 Brad Vonck Based on a survey I give my students at the end of the first semester, opinions are divided between Threshold # 3 Chemical Elements and Threshold # 5 Life. 

Our classes last 60 minutes on a 7-day cycle so we don't teach the same course every day. I use 10 classes to cover this threshold. This is the sequence I use.

I like to include hands-on activities in this unit, such as building a DNA model using gummies. For more details here is an explanation I shared in a past thread.

Thank you Donnetta Elsasser for tagging me on this post. I hope it helps.

Thank you so much! I would love to add in the DNA gummy activity, thank you for including that!
