If you have ever wanted to turn a holiday walk into real science, learning how to join and contribute to the Christmas Bird Count is the easiest way to start. Every December, tens of thousands of volunteers head outside across the Western Hemisphere to count birds, and their observations feed one of the longest-running wildlife … Read more

Last spring, my kids and I counted 47 different species in our tiny suburban backyard in a single afternoon. We saw a hawk moth, heard a woodpecker we never knew visited our oak tree, and discovered three types of moss growing between our patio stones. That day changed how our family sees our yard, and … Read more

Our team has spent the last three summers sitting quietly in our backyards, watching bumblebees bounce between coneflowers, hovering flies mimic wasps, and butterflies drift past milkweed. If you have ever wondered what is actually visiting your flowers, you are not alone. Learning how to observe and identify pollinators in your garden is one of … Read more

I have run moon journaling workshops with hundreds of students and families, and the same thing happens every time: by … Read more

I still remember the first rock I ever tried to identify. I was eight years old, holding a chunky gray stone with sparkly bits, convinced I had found a diamond. I had not. It was granite. After that humbling moment, I spent years learning the simple tests that any curious person can run at home, … Read more

The streak test for mineral identification is done by scraping a specimen across an unglazed porcelain plate (called a streak plate) to reveal the color of the mineral’s powdered form. It’s one of the simplest, most reliable tests I teach in my geology workshops, and it works whether you’re at a kitchen table, in a … Read more

The vinegar acid test for carbonate minerals is the safest, easiest way to tell if a rock contains calcite, dolomite, or another carbonate. You place a drop of white vinegar on the specimen and watch for bubbles. If bubbles of carbon dioxide appear, the rock contains carbonate minerals. If nothing happens, it does not. I … Read more

You have a crystal in your hand. It is clear, light catches its faces, and you cannot tell if it is quartz or calcite. You are not alone. This is one of the most common identification challenges for beginner rock collectors, and it trips up experienced rockhounds too when specimens are unusual. The good news … Read more
