Arizona's homeschool community keeps growing. KOLD News 13 reported on October 19 that the state's Empowerment Scholarship Account program now funds 108,688 students, and that many parents are leaning on each other to choose learning materials, including curriculum swaps planned in Pinetop in November and Surprise in December. More families than ever are building their own science lessons at the kitchen table.
The calendar is on your side, too. The Pima County Master Gardeners' November gardening guide for the low desert, published by University of Arizona Cooperative Extension, says early November is the time to sow seeds like beets, carrots, peas, spinach, chard and kale directly in the ground, and lists herbs among the good fits for the month. It also notes that the first frost often arrives in mid-to-late November, so this is a great week to get seeds going.
Before anything goes in the dirt, try a game that turns seed starting into real detective work: can your kids figure out what a seed is just by looking at it, and then prove it by sprouting it?
What your kids will learn
Identifying a seed is all about careful observation, which is the first skill every scientist needs.
Grades K–5
- Name the parts of a seed: seed coat, embryo and stored food
- Describe what a seed needs to germinate: water, warmth and air
- Observe, draw and describe changes every day
- Measure root growth with a ruler
Grades 6–12
- Classify seeds by measurable traits like length, shape and seed-coat texture
- Write a testable prediction and check it against evidence
- Calculate a germination rate (seeds sprouted ÷ seeds planted)
- Compare how long different plant families take to sprout and suggest why
This week's activity: the mystery seed detective game
You can play this today with seeds from your pantry. Dried beans, lentils and raw sunflower seeds all work well.
- Hide the labels. One adult pours three or four kinds of seeds into unlabeled cups and keeps a secret answer key.
- Observe like a scientist. Kids use a magnifying glass to describe each seed's color, shape and texture in a notebook, and draw it.
- Measure. Line a few seeds up against a ruler and record their length in millimeters. Older kids can find the average.
- Make a prediction. Each child writes a guess for every cup, plus a prediction of which seed will sprout first.
- Sprout them. Fold each seed type into its own damp paper towel, slide it into a labeled zip-top bag and keep it somewhere warm, out of direct sun.
- Check daily and reveal. Record the day each first root appears and sketch the first seed leaves. Then open the answer key. Did the seed leaves give away any clues?
When the sprouts are ready, older kids can plant them in pots or a garden bed and keep tracking growth through the cool season.
Want a real mystery? Our Surprise Herb or Vegetable Seed Germination Science Kit is built for exactly this game. Each kit includes one packet of seeds chosen by us from 50 popular varieties: 34 vegetables, from carrots and beets to kale and sugar snap peas, and 16 herbs, including basil, cilantro, parsley, dill and chives. Part of the fun is identifying your variety by its seed shape, size and color. Most varieties sprout in about 3 to 14 days, and a few herbs take a little longer.
The kit also includes digital curriculum and worksheets geared to Grades K–5, emailed after purchase: a daily observation log with space for drawings, a root-length measurement chart and an end-of-project reflection. Older siblings can use the same packet for the Grades 6–12 extensions above.
Join the growing community
Every purchase includes an invitation to Aardvark's Seed Planting For Little Hands, our private support group for families using our kits. Post a photo of your mystery seed and let other young growers guess what it is before you reveal the answer. Kids in Phoenix, Tucson and Flagstaff can trade results with families in West Virginia and Arkansas, where the seasons look very different right now.
Start your seed mystery this week
Early November is prime seed-starting time in the low desert, so this is the week to start sprouting.
