HANG OUT WITH BATS!

BatsLive is a virtual field trip into the amazing world of bats! The site contains dozens of interactive resources, including video tours, lesson plans, webinars, and printable resources about bats. Here’s their introduction to this extensive and well-done resource site:

Bats are vital to healthy ecosystems and human economies worldwide. As primary predators of night-flying insects, bats consume enormous quantities of agricultural pests and reduce the need for chemical pesticides. Yet these wonderfully diverse and beneficial creatures are among the least studied and most misunderstood of animals. Bats are threatened worldwide, and their colonies and habitats are destroyed – both intentionally and inadvertently – because of myths, misinformation, and lack of scientific knowledge and understanding. Bat populations are declining almost everywhere in North America especially due to the devastating White-nose Syndrome. Losing bats has far-reaching consequences for natural ecosystems and human economies. Knowledge is the key to their conservation and protection.

BatsLIVE: A Distance Learning Adventure is an exciting, free education program for children in the 4-8th grades and their educators, that will bring bat conservation to life in your classroom or community.

SIMPLE MACHINES NOTEBOOKING PAGES

Betsy at NotebookingNook.com has put together this neat little resource page on some of the “simple machines” we use every single day, but hardly even think about. Here’s what she says about it:

In the past, when we have studied simple machines, I found it easy to find information on this topic but not as simple to find good free resources. My son and I had an occasion to discuss simple machines this week and I remembered how difficult it was to find what I needed once upon a time and thought I’d put something together for any of you looking for something on this topic. I hope this helps.

Included in her PDF download are: Notebooking pages & matchbooks for levers, wheel & axle, the pulley, inclined plane, wedges and screws.
Also on the page are links to 5 short, simple online videos explaining and demonstrating how these “simple machines” work.

LEGO BALLOON CAR PROJECT

Okay, LEGO builders. Here’s today’s engineering challenge for you: Can you build a LEGO car that zooms across the floor that uses a balloon as its engine/source of power? All you should use for this project are LEGO parts, LEGO wheels if you have them, and a balloon.

There’s no one “right” way to do this, but you might keep in mind:
Which way the balloon opens
Horizontal to vertical stability
Balloon staying away from tires

Try to invent your own working Balloon Car first… and then, if you get finished, or stuck, or are ready to see how some other students did it and solved their own “engineering” problems, you can click the link below:
