This kid is going fishing. That doesn’t look like a normal boat though. What is he sitting in?

It’s a giant lily pad, originally from the Amazon rainforest! These lily pads are strong enough to hold kids! Look how big they can grow!

Check out what the underside of the rainforest lily pad looks like! Other rainforest plants have giant leaves too--check them out!

Palm trees have branches with lots of skinny leaves (leaflets). Think like an inventor. What could you make out of these?

Watch as this person weaves (braids) the leaves. See if you can figure out what the person is making before the video ends!

People weave palm leaves to make many different things. In Indonesia, people create these amazing wedding decorations!

Some leaves have amazing colors and patterns! But...

...this wiggly, white pattern wasn’t always on this leaf! What do you think happened to the leaf? Where did the pattern come from?

The pattern was made by a little insect--a leaf miner--having lunch! It walks in a wiggly path as it eats the inside of the leaf!

Check out these strange things on these leaves. What do you think they are? Take a guess.

These are called galls. Insects laid tiny eggs in these leaves, then the eggs made the leaves grow strange, colorful shapes (galls)!

Watch as a person touches this plant! (Wait to see what happens!) How do you think folding up its leaves could help the plant?

Some animals eat leaves. But when this plant “closes up,” it looks like there are fewer yummy leaves to eat. The leaves reopen later!

Most plants don’t seem to move at all. But if you fast forward time... check out how much these houseplants move during 1 day!
