Making Our Own Soap

I often contemplate whether or not our homeschooling approach is good.  We do a mix of online curriculum, reading classic books, and hands-on activities, not to mention the outside classes they have in art, science, martial arts and dancing.  I recently tried to decide which hands-on activities are most valuable.  It struck me that we should try to make as many of the things we use as possible - if not on an ongoing basis, at least once or twice to get a sense of what's involved.

Soap is something that I hadn't though about too much except I was pretty sure that what we were buying in the store wasn't all that healthy.  Once I researched it, however, I found out that so many academic subjects could be covered in making soap so there is value across age groups.  There's safety, chemistry, math, social studies, art, reading, and research skills.

Safety is very important since you are handling lye.  Glasses and gloves must be used.  I suit up the kids in sunglasses that wrap around with good coverage and gloves.  I also don't have them directly handle the lye.

Chemistry is obviously covered, but the real nuts and bolts of the reactions are probably better for older age groups though.  Still, my kids get a sense of it by measuring the temperature of lye and water mixture (with a non-touching thermometer) and seeing how much heat is given of when the two combine.

Math is well covered.  I have them add up the oil amounts so we know what number we are weighing to on the scale.  They weigh the oils and take temperatures.  They help me use an online calculator to determine how much lye and water is needed for the type of oil.  There is also cutting the soap trying to get as even measurements as possible and weighing the bars once they are cut.

Social studies is loosely covered since I have explained that mixing oils and lye is the traditional way of making soap back into history.  There is also the economics of selling some of the soap online and to friends and acquaintances. 

Art is somewhat involved because one can get creative with coloring and design.  Although we prefer natural soaps we stay away from too much in the way of color.  However, it is interesting to see how appearance is affected by the ingredients.  We may experiment with color at some point providing it is from natural sources.

Reading is obvious since we need to read recipes.  Although many recipes we learn by watching videos.

This brings me to one of the best thing - research skills.  We learned a great deal from youtube and doing internet searches so the kids got a sense of how to take charge and learn something independently without only relying on formal education.  It also strikes me that youtube, on some respects, is like John Holt's vision for education where there are no schools, but people finding each other and teaching what they know.  This happens when an expert puts up a good video and people like us find them and can replicate what they are doing with no classroom required.  The information is free and available.

On a related note, we did make our own dry laundry detergent.  I am not sure what we will do next in the way of things we use.  What items have you made as a homeschool project that you were able to use?
