When I went in search of curricula for some subjects, sometimes I couldn't find what I was looking for. I started pulling together a mishmash of resources, and only later started thinking of some of these as unit studies. I thought I'd share the steps I go through in creating these.
1. Choose a topic. This includes not only the general topic, but any
areas we want to focus on. We consider how deep we want to go and a
general idea of how much time we want to spend.
Example: My daughter requested a unit on chemistry. She wanted
quite a lot of information on it, definitely wants to cover the periodic
table/elements, and wants lots of hands-on. We had a big trip scheduled, which presents a natural ending point for us, so
we had about 6-8 weeks to spend on this.
2. Start gathering resources. Ask on homeschooling groups, do
internet searches, see what the library has, take a critical look at
anything we already have in the house we can use, check out online
MOOCs, field trip opportunities. The idea here is to see what is
available to you, not to do any choosing yet.
Example: "Chemistry" is rather a huge topic, so I decided to
start by asking on one of the homeschooling groups to get ideas for
materials others have found especially good. I needed to narrow the
field. I knew we had a couple things in the house, including a molecular
modeling kit, so I wanted to incorporate that. I got recommendations
for a huge amount of books, curricula, websites, apps, and kits.
3. Evaluate the resources. Some just won't fit with your goals, your
ages/abilities, your interests, your time frame, your budget. You might
want to keep a record of these for the future, but take them out of your
options for now. Some will hopefully be standouts and have you and your
child really excited about jumping in - these are the essential pieces
you can most build your unit around. Some are very good, but not
spectacular - if they are affordable, then these are great to have on
hand for open exploration even if you don't formally incorporate them
into the unit. Some may not make you excited, but are the best choice
for fulfilling some aspect of your goals.
Example: So much stuff! I find this the most overwhelming part of
planning a unit because I want to include ALL THE GREAT STUFF! I had
been wanting to try the Ellen McHenry units for a while, and she has one
called The Elements, so I looked at a sample with my daughter, who
agreed it appeared to be a good fit, so that became one of our main
pieces. There are games in that, but not much in the way of experiments, so I needed
something to fulfill that piece. I was planning on a traditional
chemistry set, and Thames and Kosmos has some decently well rated ones
at a fair price, so I looked there. While looking there, I came across
Candy Chemistry - light on the chemistry but heavy on the fun and the
candy! My daughter is young, and we'll definitely do more serious takes
on chemistry later, so I went with Candy Chemistry. The kit is a bit
ridiculously priced, so I downloaded the manual for free and gathered
the supplies. There are some great books that were available at the
library, and some recommended apps that were priced ok, so I added those
to the stack, though I don't intend to formally include them. Add in a
periodic table placemat, and videos from subscription sites we already
have and we can easily fill our time!
4. What else can I incorporate? What can I let go of in the rest of our schooling?
Example: We were ready for a break from formal math, and
there's a fair bit of math in chemistry anyway, so we shelved
our math program for a bit. She kept some notes and did some
written activities, so handwriting was covered. We were just about to
do a bit on crystals in science anyway, so we did that and also
included the crystal growing kit I had for that - fits in perfectly
alongside the chemistry unit!
