Recently, I made a scarf coded in ASCII. (Here is the post.) Your family could make a Binary Birthday Coding Necklace. What other crafts are stem-related? Look at this introductory sewing lesson, which has an emphasis on understanding metrics and doing metric and English conversions. Here is an article describing some of the basic mechanics in a sewing machine. Tennessee 4H has experiments with fabrics and dyes. Here is a tie-dye guitar pattern from Dick Blick. (Dharma has this information regarding the underlying chemistry.) Here is an activity from ACS about dyeing a t-shirt with Koolaid. Molecular Gastronomy is another avenue for STEM instruction. Science in School has this article and experiment about using sodium alginate with calcium chloride (or calcium lactate). If your family likes making sodium alginate beads, take a look at this guide and add fruit juices. Friday afternoons are a great time to plan family STEM activities—right after lunch, before the kids head outside!
