Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do citizen scientists count butterflies?

The Big Idea

Citizen scientists count butterflies to help real scientists learn! Citizen scientists are volunteers who collect information, and you can be one! One person cannot count everywhere, but thousands of volunteers can.

Count Them

Step one: count butterflies. Volunteers count butterflies in yards, parks, and meadows, sometimes with a family or a club. They write down what they see and when, and how many.

Share the Data

Step two: share the numbers. Counts from many places and many years go to researchers. That adds up to a big picture that one person could never gather alone, like many puzzle pieces fitting together.

Spot Changes

Step three: learn from the data. Scientists can see how butterfly populations change. They can tell which species need help, and where to protect flowers and habitat.

A Closer Look

Let's take a closer look! First, watch quietly from a distance, in a sunny spot with flowers. Count each butterfly you see, and note the color. Write down the numbers and the time. Then share them with the scientists.

Quick Facts

Quick facts! Many butterfly counts happen each summer in Canada. Thousands of volunteers help scientists, from kids to grandparents. Butterflies are pollinators that help flowers make seeds. Look with your eyes and do not catch or touch butterflies.

Think Like a Scientist

Now, think like a scientist! Count the pollinators you see in a flowery spot for ten minutes, such as bees, butterflies, and flies. Write down the numbers and the time, so scientists can compare days. Do it again another day. Did the counts change?

Outro

Anyone can be a scientist by counting butterflies. Science is amazing! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
