I have done this lab for 17 years now and it is the most memorable lab that I do. I have former students that are now adults that remember this lab. I don’t buy any of the ingredients, we discuss it days before and the students get in groups to decide who brings in what ingredients. On the day of the lab I have students bring in their materials in the morning and I have 5 different coolers for my five different periods. I only have them place what needs to stay cold in the cooler and rest of the ingredients they keep with them until they arrive to my class. However, when I do this lab in my summer school special ed. class I just purchase the materials using department money. What I provide are buckets large enough to fit a 7-10lb bag of ice in.
I provided background information on the science behind the chemistry of ice cream as well as a YouTube clip from the American Chemical Society that’s entertaining and informative, so you won’t need to lecture or provide much scaffolding leading into this lab.
The directions are easy to follow but I’d still model the lab and the two biggest mistakes students make are putting too much vanilla in their ingredients and getting salt in their ingredients. This is why I use two zip-lock bags to ensure no salt gets in ice cream and that they rinse the salt off the bags once their ingredients have solidified. Salt will absolutely ruin their ice cream!!!
This lab is great for mainstream, special ed. and English Language Learners, there is a flow chart and fill in the blank paragraph with a word bank. This Lab includes the following concepts:
