Tiny butterfly caterpillars arrive in their own cup, complete with food, paper cover and ventilated plastic lid. Watch the caterpillars eat and grow, grow, grow! Once they have reached full size, caterpillars will migrate to the top of their cup, hang from the paper and form beautiful chrysalises. Gently remove the perforated plastic lid, peel back the paper layer with attached chrysalises and lift away from the cup. Use tape or a piece of wire (an unfolded paper clip or trash bag twist tie work well) to hang paper with chrysalises from the wall of the paper butterfly house. One by one, chrysalises will slowly open to reveal a new butterfly emerging! New butterflies will slowly open their wings to dry; red pigment may drip to the floor of the mesh house. Once you see butterflies actively flying around the mesh house, you may feed and keep them up to a week or release immediately. It’s warm enough for them outside once daily temperatures reach at least 55 degrees F.
Our Sunflower Challenge comes with 25 individual seed packets and instructions for sprouting seeds right in your classroom. Create pots from cups, newspaper, egg cartons or pop-up seed starters. Plant your seeds, watch them sprout, observe as they grow and then transplant to larger pots or outdoor garden areas. Send a seed packet home with each child so they can try to grow sunflowers from seed to bloom over the summer. Children are invited to submit a picture of themselves with their blooming plants. Earth's Birthday Project sends back a prize. It's our way of saying "Thanks for being kind so kind to our Earth!”
