Flashcards

Soil Life Flashcards

Eight 4-inch cards with real microscope photos on the front and what each one does in the soil on the back: fungal hyphae, mycorrhizal fungi, bacteria, actinomycetes, flagellates, ciliates, a bacteria-eating nematode and a root-eating nematode.

Try this

  • Hold up a card: who can name it?
  • Sort them: who eats whom in the soil food web?
  • Then find them for real in the microscope simulator.
Card games

Microbe card games

35 soil microbes from the microscope game, each with a picture, a name and a fact. Print once, play four ways.

Printing tip: print the one-page alignment test first. It shows whether your printer flips on the long or the short edge, so the backs of the cards line up.

Dr. Dirt's Bingo

Twelve different boards and a caller's spinner with all 35 microbes. A whole class can play.

Dig Deeper

Like Go Fish, but you say "Dig deeper!" Most pairs wins.

Guess the Microbe

Ask yes-or-no questions to find your partner's secret microbe, Guess Who style.

Board game

Dr. Dirt's Living Soil

A board game for 2 to 4 players with no dice: plant seeds, raise your farm's soil life, sell your harvest at the market and team up to build a food web. One lap of the board is one year in the garden.

Your turn, in four steps

Do a farm action, grab a Move card, read your new space, next player. Easy enough for young players, with real choices for older ones.
