Depending on where you live (in the northern hemisphere), spring may already be on its way. Buds are swelling, opening, flowering... providing the first pollen of the year for bees.
Some tree buds open earlier than others. A good way to get to know the signs of spring in your area is to "adopt" a tree in your back yard or the local park. Visit it every week and take photos or draw pictures of what the buds look like.
- What sort of flowers does it have?
- When do they open?
- What do the flowers look like close-up?
- How long do they last?
- When do the leaves burst out?
You can become a "citizen scientist" bud-watcher for Project BudBurst and share data with others - check out their website
here. One thing scientists have noticed is that buds are opening earlier and earlier each year. People's observations are contributing to their understanding of
how climate change is affecting the natural world.
