Friday Fun: Five Gross and Goofy Body Facts

1. The word arm comes from the Latin term arma, which means “tool.”

2. A sea star’s feet are on the underside of its arms

3. An octopus uses its arms to grab prey and to jet through the water.

4. Lobsters, crabs, and scorpions fight off enemies and grab prey with clawlike pincers on their front limbs. Are those limbs arms or legs? It depends on who you ask.

5. Most dinosaurs walked on four legs, but not T. rex. It had two tiny arms with sharp claws. How did the massive meat eater use its little limbs? Nobody knows. They were strong enough to hold prey but too short to reach T. rex’s mouth.

Behind the Books: A Year in Pictures

As the School year winds to a close, I thought I’d post some of my favorite images from school visits. Since September, I’ve presented to students in Massachusetts, New Hampshire, Maine, Virginia, Georgia, Oregon, and Pennsylvania. Phew!

Wherever I go, I learn as much from the students as they learn from me. They inspire me, and they aren’t afraid to tell me if they think I’ve made a mistake. So here are some great moments with all those terrific kids.

Behind the Books: Even More Super Silly Science Jokes

Changing a few little letters sure can make a big difference! Sometimes you get two words that sound exactly the same, like see and sea. But you can also end up with words that sound almost the same, like lion and lying or cheetah and cheater. And these word pairs can be the inspiration for some jokes that are very a-moose-sing. Oops, I mean amusing.
Here’s an example:

Q: What kind of test did the teacher give the young wolves?
A: A pup quiz.

The great news about jokes is that you can often recycle them. For example, you could tell this same joke about young dogs, seals, coyotes, foxes, sharks, or walruses.

Here’s a joke that dates back to prehistoric times.

Q: What do you get when two dinosaurs crash?
A: A Tyrannosaurus wreck.

Maybe you’ve heard a lot of banana jokes in your time. Here’s a joke that involves a very different kind of plant. If you like nutty jokes, give this one a try:

Q: What did the nut say when it sneezed?
A: Cashew.

Now it’s your turn. Can you or the kids you know think of jokes that use these similar-sounding word pairs?
• calculator/cowculator
• asteroid belt/asteroid bell
• poached eggs/pooched eggs

Feel free to post your best jokes in the comments. We could all use a good laugh.

Be on the lookout for more joke-writing posts in the future. And check out the Super Silly Science Jokes I post on Friday.

Cool Clouds: Predicting the Weather

I haven't seen altocumulus clouds liekthese since last September. They're often a sign that the weather is about to change, so I wasn't surprised that a few hours after I snapped this photo , we had our first thunderstorm of the year. And the weather is now noticably wetter and cooler than it was last week. Imagine what it would have been like to live in the days when analyzing the clouds was really the only way to forecast the weather.

Friday Fun: Five Gross and Goofy Body Facts

1.   Your hardworking heart never takes a break. The fist-sized lump of cardiac muscle beats about eighty times a minute day and night, year after year. You don’t even have to think about it.

2.   During your lifetime your heart will beat about 3 billion times and pump about 100 million gallons of blood into your blood vessels.

3.   As the layers of smooth muscle lining your blood vessels contract, blood surges forward on its 60,000-mile journey through your body.

4.   Blood whizzes through your arteries, traveling at 1 foot per second. But then it puts on the brakes as it squeezes through your super-slender capillaries. Finally, your blood slowly slogs its way back to your heart through your veins.

  1. Right now your body contains about 6 quarts of blood. About 24 percent of that blood is in your arteries. About 66 percent is in your veins, and about 10 percent is in your capillaries.
