Fossil Lesson Plans from Dinosaur Train!
I couldn’t resist. I will definitely be using this with my little Dinosaur Train fanatic.
An Illustrated Guide to Fossil Collecting by Richard Casanova and Ronald P. Ratkevich. A fundamental book on fossils and fossil collecting, it starts out with a brief history of collecting incuding some of the famous collectors of the past like Mary Anning who was twelve when she found a complete skeleton of Ichthysaurus. Following a description of fossils and how they are formed, is a discussion of fossil classification. Sounds technical but it is written for the real person who collects for his or her own bookshelf. There is a generic chapter on the history of the Earth, evolutionary, of course, but written from the ecological standpoint. Chapters on how to collect and display your fossils are included. Lists of resources with museums, geological surveys, societies and paleontological libraries finish up the book. The best chapter in number seven. This is the chapter on fossil collecting localities in North America. This is definitely the resource you need to find fossils on your vacation trips. Recommended for all ages.
Dry Bones…and other fossils by Gary Parker. A Master Books publication, this one is written from a Creationists viewpoint. It is a dialog between Dr. Gary Parker and his family on a typical fossil hunting trip in Indiana, Dr. Parker covers most of the bases in the creationist story of the Earth from creation to the big flood, explaining fossils and how they are made. This book also comes in a read-along tape version for your little ones.
The Illustrated Origins Answer Book by Paul S. Taylor. A wonderful reference book for older readers, the Answer Book has two parts: a textbook and a reference section. The text is very concise having good definitions which are not oversimplified on the page the word occurs. This book is not for young children, but for interested adults and older children who have been wondering about some little problem with scientific creationism, but didn’t know where to look. There many quotes from scientists, creationists as well as non-creationists, in the reference section. A handy reference for creationists who may become involved in debates or lively discussions.
Field Guide to North American Fossils by Ida Thompson. Photographs! In color! This field guide claims to be the first all-photographic one published. Written for the field, the guide is valuable to have in your field pack so that you can identify that odd fossil without losing face before your children. Actually, any age can use this great little guide. It is, of course, evolutionary and has a description in the first part of the history of the Earth period by period. There are interesting details of recent research in this discussion, so don’t overlook it just because of the evolutionary bias. After the photo section is a chapter which uses words to describe the fossils of that type. The discussions are correlated to the photos.
Roadside Geology Series This series is wonderful for keeping in the car on a trip and reading along as you ride through the countryside. Most of the major routes through a state are covered in the books and a lot of the minor ones. Geology is best studied outside and these books help you do that. They help you figure out what is going on with the Earth as you travel past roadway cuts and outcroppings. The book for Texas covers the different geographical sections (examples are from Southeast Texas: Upper Gulf coast), the typical landforms (like saltdomes and rivers), the different processes still going on (like longshore drift and hurricanes), and the larger routes (like Interstates 10, 35, and 45) and US routes (59 and 290) and state routes (36) The glossary in the back and lots of pictures throughout the text make it simple to understand. Most states are covered, you can purchase the books at The Geology Store.
Dino-Trekking: The Ultimate Dinosaur Lover’s Travel Guide by Kelly Milner Halls. This is another traveling book, but you’ll use it before you get in the car. Well-known and not so well-known dinosaur sites are listed and described here. In the margin are the details like address, admission prices, and facilities available. There are side boxes with interesting notes from the curators of some of the museums and parks. The last section is a description of many dinosaurs plus a few non-dinosaurs which are included. Useful for dinosaur lovers.
Here are some activities for you to try at home as you study fossils!
1. Make a cast of a footprint.
Find a really nice paw print of a dog, of a cat, or of some other animal. Clear away the leaves and debris from the outer edges of the print. Take a 1-inch wide strip of card stock (an index card works well) about 11-inches long (longer if necessary) and staple it into a circle. Place the card circle so that it surrounds the print like a fence. Dig it into the dirt a little so that it is secure. Pour plaster which is the consistency of toothpaste into the print and the fence. Let set and remove. You should have a cast of the print. If you do not have a good footprint, make one using your dog, a little dirt, and some water. Make mud and press your dog’s paw into it. Allow the print to dry until it is hard enough to keep it’s shape when touched. Then make the cast as before.
2. Making a plaster copy of a footprint.
After your cast of the animal footprint has become firm, put a thin layer of petroleum jelly all around the inside of the cast. Put another card stock sleeve around the casting to make a cuplike form. Pour plaster of paris at a toothpaste consistency into the cup. Allow to set. Remove the card stock and separate the layers. You should now have a plaster copy of the foot print. You can do this with your little sister’s hand print, too.
3. Dissolving the bone / the first step of replacement.
When a future fossil is replaced by minerals it is done very slowly, a particle at a time so that the structure of the original organism is still preserved by the replacing minerals. Sometimes even the cells of the plant are able to be seen even though the original cells are long gone. This is how the trees were petrified in the Petrified Forest. The water first dissolves the material of the organism, then replaces it with another particle, a mineral. Some fossils are replaced with beautiful agates and are turned into wonderful specimen you can use as decorations at home.
You can not try replacement, but you can experiment with the first part of the process, the removal of the material of a bone. Place a chicken bone in a glass of vinegar or of carbonated water. Each of these liquids are acidic and will dissolve the calcium out of the bone leaving the cartilaginous material which bends easily. When a tooth is placed in carbonated water, it will dissolve completely. Ground water filtering through a future fossil may be acidic. This acid will dissolve the calcium in the organism leaving a spot which may be filled by a mineral also in the water. A useful tip: You can increase the calcium content of a stew by adding the bones of the meat along with a tablespoon of vinegar. You will not taste the difference but the stew will have a considerable amount of calcium in it taken from the bone by the acid.
4. Fossil hunt
You can make up some artificial fossils by putting objects to be excavated into a matrix which is then carved away to reveal the “fossils”. What you choose to place into the matrix should depend upon the age of the child and whether it is to be eaten during the experiment.
There are several different things you can use as the matrix. Some people prefer using plaster of Paris because of its rock-like texture, but it is hard and can be difficult to carve. If you use this matrix be sure to use eye protection. Parafin can be used and then carved easily with nails and popsicle sticks. You can simulate different rock layers by using crayons to color the melted wax. Remember to be careful with the melted wax. You can even use cake dough and cook some whole pecans into the dough. Excavating can be done with forks and spoons. Jello is another matrix you can use for the “fossil” excavation. If using an edible matrix, be sure to use edible “fossils”.
The best type of fossil hunt you can do, though, is outside hunting real fossils. If you live in a city, look for building made of limestone, marble, or some other once sedimentary material. Many building materials have fossils in them. Marble, though, once sedimentary has been metamorphosed and changed by pressure or temperature. The fossils within will have been changed, too, but in many cases are still recognizable. Many libraries have shells embedded in their steps and we walk over them without ever noticing them.
5. Collecting data.
Use a 3×5 Data Card to record notes while collecting fossils. You may forget where you collected the specimen and you may want to remember a particular location. On a 3×5 card, jot down the following notes:
Name of the fossil (type of creature or plant, if you know it):
Rocks the fossil came from:
Drawing of the position of the fossil in the rock:
Location of collection site: Get out and collect some fossils and try some of these activities! Stay tuned for part 3 of this post: Internet and Print Resources for the study of fossils.
