After a flower is pollinated, it makes a fruit with seeds inside. The fruit helps the seeds travel away from the parent plant. Seeds can be carried by wind, water, animals, or even by popping out of their pods. Spreading seeds far away gives baby plants more room to grow.
Collect different fruits and seeds (dandelion puffs, maple spinners, burrs, berries) and discuss how each one travels. Blow dandelion seeds and watch them float. Stick burrs to a sock and walk around. Cut open fruits to find the seeds inside.
After a flower is pollinated, something wonderful happens: the flower transforms into a fruit. The petals fall away, and the part of the flower that received the pollen swells up and grows. Inside this fruit, seeds are forming. The fruit's job is to protect the seeds and help them travel to new places.
Think about all the different fruits you know. An apple has seeds in its core. A strawberry has tiny seeds on its outside. A peach has one big seed (called a pit) in the middle. Even things you might not think of as fruits — like tomatoes, peppers, and pea pods — are fruits because they came from flowers and hold seeds inside.
But why do seeds need to travel? Imagine if all the seeds just fell straight down under the parent plant. Dozens of baby plants would all try to grow in the same tiny spot, fighting for the same water, sunlight, and soil. None of them would grow well. So plants have clever ways to spread their seeds far away, which is called seed dispersal.
Different plants use different methods. Dandelion seeds have fluffy parachutes that catch the wind and float far away. Maple seeds have wings that spin like helicopters. Berries are eaten by birds, who fly away and drop the seeds in their droppings. Burrs have tiny hooks that stick to animal fur (or your socks!) and get carried to new places. Some plants, like touch-me-nots, have pods that pop open and fling seeds into the air. Each method is a different strategy for giving baby plants the best chance at a good spot to grow.
