Is it possible to leaf whistle

Or you might see insect eggs or larvae. Can you hear any insect sounds? If you see loose bark, shine a flashlight into the crack between the bark and the log. Is anybody looking back? If the log is hollow, stand back a few feet and shine the light inside, too.

Be careful, though. A hollow log might be home to a sleepy raccoon, opossum, or other animal. Go ahead and turn the log over -- as long as you turn it back when you're finished. And don't take anything. You can come back again at another time of the year to see if anything has changed. Kids can walk like the animals for a fun race with friends at a park or the beach. They'll need to think about how different animals walk.

That's because everybody runs like a certain animal in each race of this easy nature activity for kids. A grass whistle is quick for kids to make and fun to blow when you're out on a hike. It's among the easiest nature crafts for kids.

Step 2: Blow into the crack between your thumbs, so the air flows over the grass. You should hear a whistling sound. Step 3: If you don't hear anything, move the blade of grass a little, and try again. You'll soon get the hang of it. Collect water vapor from plants to prove that they perspire. This means that plants' leaves give off water vapor. You can't see a plant perspiring, but this experiment shows you how it happens.

What happens? What do you think is the source of the moisture you see in the bag? It comes from the leaves through tiny pores on the undersides of the leaves. Because these Rules form a legally binding agreement with respect to this Contest, please read them carefully.

Hawaiians developed the practice by using leaves from the ti plant and blowing into their hands. Leaf whistling works much the same way as reed instruments such as clarinets and saxophones.

With reed instruments, the vibration of the reed from your breath creates the sound. You want to create an air chamber with your hands for the leaf vibrations to resonate. If you are struggling to make the leaf vibrate, tear it into a smaller piece and try again.
