Show the concept of the vernal equinox and play a simple game with day and night flip stones, an easy garden activity for kids. On the day of the vernal equinox (March 20 or March 21), the hours of day are nearly equal to the hours of night. The flip stone shows this with a painted sun on one side and a moon on the other.
What You'll Need:
- Smooth round stones
- Old newspapers
- Acrylic paint
- Water cup
- Clear varnish or nail polish
Step 1: Find a smooth, round stone. Wash it, and let it dry for several hours.
Step 2: Lay out some old newspaper on your work surface.
Step 3: On one side of a stone, paint a bright sky-blue background. Make sure you don't get any paint on the other side of the rock.
Step 4: When the blue paint dries, paint a large, smiling sun in the middle of it.
Step 5: When that side dries, paint the other side black.
Step 6: Add a crescent moon when the black background is dry.
Step 7: To protect your painted stones, coat them with clear varnish or nail polish once you're done painting them. You might want to do two or three coats, waiting for each coat to dry before you add another.
Now you are ready to play a toss game, much like heads or tails. Take turns calling "day" or "night" and tossing the stone on the grass to see if the side you called lands face up. Keep score, and see how many "days" and "nights" you can guess.
Paint other rocks with pretty spring scenes, and give them out as prizes.
How powerful are plants? You'd be surprised. Look on the next page for an experiment that shows plant power.
