Resources for Geologic Time

Slideshow to go with Chapter 14

Greek and Romans found dinosaur fossils too - a podcast on how cultural context influences interpretation of findings

A pretty good geologic time line for 7th graders.  A little more info than you need, but not TOO much!

Can you put together dinosaur bones?  This is a fun paleontology puzzle.
A very pretty pictoral time line with visuals of what the earth may have looked like at all kinds of different points in Earth's history.  Click Start the Journey.  Skip through the introduction to see the much more interesting whole time line.

Lots of fun paleontology activities to do here.

An interactive tutorial on geologic time, including some of the stuff we've already learned (fossils, relative age, absolute age), but worth having another look at anyway.

Big 5 Mass Extinction Events from the BBC - very nice!

Asteroid Theory (National Geographic)

Western Black Rhino Is Now Extinct

Coincidentally, we were just talking today in class about how extinction in general is a non-event in the geologic time scale, while mass-extinction is something different entirely.  Just saw this article about the Western Black Rhino's status changing to "extinct", as the last living animal was observed in 2006.


I'm not really sure how I feel about this "non-event."  Feels tragic to me...

Resources for Fossils and Geology

Here are some videos and other links that help illustrate some of the principles in Chapter 13...

This video illustrates the law of superposition in an easy-to-understand way.

This video explains absolute age and how we can use Carbon 14 isotopes to date once-living things.


This is the "Nerd-Version" for anyone who wants to really, really understand radioactive decay!


Recipe for Salt Dough for homework.  If you don't have any clay or plaster or playdough, you can make your own.  Use sand, pebbles, dirt, spices, whatever... to make the different layers of rock.

Thinking About the Food Drive...

 
This is a video of a TV chef showing how to prepare some delicious food you can find at the food bank.

Here's what's on my mind.  Every year we have a food drive at school, and donate tons and tons of food for the local food banks.  This year, I'd like to push our food drive to a new level.  I want to learn more about how food banks and soup kitchens work, what kinds of people are "food insecure", what kinds of people volunteer at soup kitchens and food banks, and how to best get involved in helping the needy.  So I've been doing a little research...

Ever thought about "volunteering at a soup kitchen"?  I think it's something a lot of people talk about, but I wonder if anyone ever actually does it.  I looked into volunteering at a soup kitchen and was shocked to see what goes into providing enough food for all the hungry people who show up for lunch.  Here are the volunteer guidelines and soup recipes for a soup kitchen that serves between 700 and 1000 meals a day.  In Denver, you have to be 14 to volunteer...  )-:  But we can still help out in our own way, right?  (-:

Food Bank of the Rockies is a great place to volunteer if you are over 14.

I've also been thinking about the kinds of foods we donate to the food bank.  Most years we reward students for the number of food items brought in.  This means that kids are bringing in whatever unused stuff they have in their own pantry that no one wants to eat, or they are buying really cheap items, like ramen noodle soup, so they can get the most reward for their dollar.  But if I was in need of help feeding my family, and all we had to choose from was creamed spinach and ramen noodles, I would really worry about whether or not my kids were getting balanced, healthy nutrition.

I'd sure like to see kids bring in LESS food, and make it MORE of the stuff people would really want to eat, and which would help them meet their nutrition needs, rather than just fill the food drive box.

Here is a list I compiled from my research about what food banks are asking for...

  • Peanut Butter (provides ready to eat, kid-friendly, portable protein)
  • Cereal (less sugar is better)
  • Tuna and other canned meat (non-perishable protein)
  • Beans of all kinds - dry, canned, pinto, black, refried, kidney
  • Rice - instant, wild rice, brown rice, or any kind of rice
  • Macaroni and Cheese - easy!
  • Chili - dry mix or canned
  • Canned Stews - filling, easy to prepare, great for small portions (seniors who live alone, etc)
  • Canned Soups - lower sodium is better, chunky soups are more filling
  • Canned Lunch Meats
  • Full Meals in a Can/Box - many people don't have the extra ingredients needed to make a recipe from scratch.  If all of the ingredients are in the box, that is often better
  • “Pop Top” Food Items - something most of us wouldn't think about...  some folks don't have can openers, or have arthritis and can't operate them.
  • Non-food items - food stamps can't be used on non-food items - things like diapers, toothbrushes, toothpaste, cleaning products, shampoo, feminine hygiene products, deodorant, coloring books, etc.
    I also found that there are many items people try to donate to food drives, but the food banks can't take them.  Here is a list of items you can't donate to a food bank...
  • Home-canned or Homemade Goods
  • Rusty or Unlabeled Cans
  • Alcoholic Beverages, Mixes or Soda
  • Opened or Used Items
  • Glass Containers (they may break)
  • Baby Food in Glass Jars (but baby food in boxes or plastic jars is okay)
  • Over-The-Counter or Prescription Drugs
  • Food After or Very Close to its Expiration Date
Here is a cool poster you can print to help advertise the items most needed...

 Know what else I learned?  Dollar for dollar, your donation goes a lot farther if you just donate money to the food bank, rather than share your dollar with the grocery store.  Food banks can buy a lot more healthy food at a better discount, using monetary donations, and can even buy some perishable items, like fresh fruits and veggies.  My conclusion, if you have food in your pantry your family will not eat, by all means, donate it!  But rather than buying items from the grocery store simply to donate for a food drive, you'd be better off giving your money directly to the food bank.  Here is a link you can use to donate money to the Rocky Mountain Resource Center.  https://www.givingfirst.org/addToCart.do?organizationId=27214What could be easier?

 One more thing I discovered is that often times people don't know how to prepare the bulk ingredients found at their food bank. People often prefer the pre-packaged convenience foods because they are easier to make, but they are not very good for you.  Also, they get snatched up quickly from the food bank shelves, leaving only ingredients that need preparation.  I found one simple cookbook with recipes designed for food bank clients.  I was thinking students at FMS could prepare a cookbook and have it printed, and give them to the foodbank in addition to our food donations.

Well, these are all big ideas, and I can't pull them off by myself!  If you are interested in being a part of my little project to take the food bank to a new level, please contact me at the school.
