Each stage in a butterfly cycle involves complete metamorphosis. From egg, larva, pupa and adult stages. Once a caterpillar has reached maturity, they form a protective outer shell called a chrysalis that shields them until they’re ready to transform into butterflies. Caterpillar Stage When butterfly eggs hatch and develop into larva, they quickly transform into […]

Flowers play an essential part in our ecosystem. Not only are they beautiful, attracting pollinators and providing food to animals; but flowers also filter toxins out, recycle carbon dioxide back into the atmosphere, and generate oxygen through photosynthesis. All plants go through an annual cycle of growth, flowering and producing seeds. Seedlings produce flowers which

Plants are multicellular organisms that use photosynthesis to produce food from water and sunlight, with life cycles marked by alternation of generations – in other words, diploid sporophytes alternate with gametophytes that reproduce sexually or asexually. Many plants begin their lives as seeds that germinate and develop until reaching maturity, producing flowers and seeds to

Students can use this diagram to gain an understanding of the complete transformation that happens between caterpillar and butterfly; also known as metamorphosis. Once it reaches its maximum size, the caterpillar begins molting (shedding of its old skin) before creating its cocoon or chrysalis for future development. Mating NARRATOR: When male and female butterflies mate,

Students can act out the life cycle of a plant. Start by having students curl themselves into tight balls as seeds. Under optimal conditions, seeds sprout and become seedlings, before developing into mature plants producing flowers and setting seeds which are dispersed through wind, water or animals, continuing the cycle. Seed Every plant begins life

Flowers come in all sorts of shapes, colors and scents; their main purpose being to attract pollinators insects while producing seeds that perpetuate the species. Seeds contain miniature plants called embryos. Each seed has a hard shell called a seed coat to protect it, which allows germination to occur quickly. Once sprouting occurs, embryos develop

Explore Earth’s continuous cycle of water movement with these books, activities and classroom lessons on the water cycle. Readers of this straightforward book discover that water evaporates into clouds, then condenses to form rain and snowfall, with this precipitation coming from oceans, seas, lakes, ponds and rivers as their source. Clouds Cloud formation is an

Seahorses are unique among vertebrates in that males carry their offspring. They live in coral reefs or other marine environments where their natural camouflage helps them avoid predators. Furthermore, their prehensile tails allow them to grasp onto objects for better gripping power. Males get pregnant Seahorses are notable examples of animals defying gender norms. While
