Rattlesnakes of Arizona
 

Here are some ideas to incorporate the Rattlesnakes of Arizona poster into your third grade classroom. The appropriate standards are listed below each activity.

Size

Create a bar graph showing the lengths of the different rattlesnakes found in Arizona. Does there seem to be any pattern? Are they randomly distributed or do they seem to be clumped around a particular size? Is there a relationship between the size of the snake and its habitat? Is there a relationship between the size of the snake and the types of animals it eats?

Aging

Many people believe that you can tell how old a snake is by the number of segments in the rattle. However, this is incorrect. A snake gains a segment each time it sheds. Sometimes a snake can shed more than once a year. In addition, segments often break off. Even though you may not be able to age a snake by its rattle, there are some organisms in which you can use some physical feature to age it. Research other animals and plants for which this is true.

Fears

Many people are afraid of snakes. Often this fear is the result of misunderstandings. Develop a survey that you can ask your family and friends. Ask them whether or not they like snakes. Be sure to include questions which allow them to explain why they have their opinions. Do you notice any patterns? Do you think if you educated these people about snakes, their opinions would change?

Media Portrayal

Think about recent stories (whether they are from books, television, or movies) that you have seen that contained snakes. Were they portrayed in a positive or a negative manner? Choose one in which you feel snakes were represented unfairly. Rewrite the story to include an accurate description of these animals.

Safety

Living in Arizona we have to take precautions to insure that we are not bitten by a snake. These might include wearing long pants and thick boots. Use a computer to develop a flyer or brochure on snake safety tips that local parks could hand out to hikers. In addition, you may consider researching proper ways to deal with snake bites and including this in your promotional material.

Benefits of Venom

Although rattlesnake venom is dangerous to humans and small animals, it may also be helpful. In fact, scientists are currently researching different diseases that may actually be treated with rattlesnake venom. Use the Internet to find ways in which rattlesnake venom may actually help humans.

  • Technology: Standard 5, Foundations 1, Objective 2

Classification

In Arizona, rattlesnakes are divided into two different genuses: crotalus and sisturus. Although all are considered rattlesnakes, those belonging to one genus are thought to be more closely related to each other than they are to those of the other genus, much like you are more closely related to your brothers and sisters than you are to your cousins. Research the difference between the two genuses.

  • Technology: Standard 5, Foundations 1, Objective 2

Diversity

Research the number of rattlesnake species found in the United States and the world. Design a graph which can compare the number of rattlesnake species found in the world, the U.S., and Arizona. Is it best to use a bar graph, line graph, pie chart, pictograph, or some other graph? If possible, make a similar graph which shows the number of rattlesnakes in each area that are protected.

Dangerous Bites

Create a graph using the information in the chart below. Use the Internet to research additional animals and include that data in your graph. Some animals you may include are alligators, mountain lions, rodents, and skunks.
