Frosty the Snowman Meets His Demise An Analogy to Carbon Dating

Earth Science

In the first part of the activity, students are asked to sequence cards by identifying and ordering overlapping letters found on the cards. Don't see the need for quiet seatwork when we could be doing something more lasting, like a game or lab or powerpoint or other more active activity. This topic will review concepts in earth science that have previously been discussed and will expand upon the principles that help us interpret planet Earth. This lesson is the third in a three-part series about the nucleus, isotopes, dating louisville and radioactive decay.

  1. No words or sound effects this time!
  2. For example, students should discuss which fossils are making their first appearance in a particular segment and which fossils have disappeared.
  3. You may group them in any size group, but working in pairs is optimal for this exercise.

Below are some additional resources to help you along the way, prepare you for your midterm exam and the Earth Science Regents exam. We have the students make the timelines and then answer the Timeline Comparison Questions. Students should have the skill to set up a data table and a graph, however, if you want to use this activity with students that have not, you can provide them a template with that information. However, the carbon that was in the organism at death continues to disintegrate. Students will use a simple graph to extrapolate data to its starting point.

Activity 7 Relative Dating

In this topic we will learn about the beginnings of Earth. It's an experience they'll never forget well, maybe in time. In this way, are leda and they get practice reading graphs and using them to understand and interpret data. The element carbon is an essential element in all living matter.

For more great activities on half-life and radiometric dating, see the lesson plan entitled Determining Age of Rocks and Fossils by Frank K. This hands-on activity is a simulation of some of the radiometric dating techniques used by scientists to determine the age of a mineral or fossil. By measuring how much carbon is left in a sample as well as its radioactivity, we can calculate when the organism died.

M & M Decay

Mathematics is important in all aspects of scientific inquiry. Wonderful review of many of the concepts we've been covering in our Geology Unit. Do you think scientists can use more than one type of isotope to date the same rock or fossil? Click here for a lesson on how to teach your students to calculate half-life using a simple table.

Lesson evolution Date a Rock

This is such a common standardized test subject, so it's worth covering well. Consider taking your students on a simulated journey back in time in our Time Machine. Number of parent isotope atoms. We will also focus on earthquakes and how we use seismic waves to locate their epicenters. New information needed to be introduced with parent and daughter isotopes.

This topic looks at minerals and rocks and helps us to understand the different properties needed to identify them. It focuses on latitude and longitude and applies that to more detailed topographic maps used by geologists and other earth scientists. For students, and understanding the general architecture of the atom and the roles played by the main constituents of the atom in determining the properties of materials now becomes relevant. Students will understand how scientists use half-lives to date the age of rocks. All the suspects have holes in their alibis.

Here are a couple of good sequencing games. The Missouri is two meters. Moreover, this chapter will revisit sedimentary rocks and see how the sediments produced during weathering factor into the formation of the different rocks. Here is a good version of a half-life lab using pennies in shoe boxes.

Then students take the class data and create a graph comparing the number of parent isotopes to the number of half-lives. Once all groups finish, each group records their info on the class decay table on the board and we calculate the averages of the class. See the Time Machine lesson for specifics. Did you find this resource helpful? You'll want to teach how to sequence rock layers during this unit.

In this topic we will focus on Earth's interior and how, through the use of seismic data, we have come to understand the different properties within Earth. When an element has atoms that differ in the number of neutrons, these atoms are called different isotopes of the element. Both parts of the activity can be completed in one class period.

You can make your own or surf the Web for other images you could use. In this lesson, students will be asked to consider the case of when Frosty the Snowman met his demise began to melt. Consider using other items to replace the beans and popcorn. It might be worth the trouble for you to make up one similar to my Missouri version for your own state's geologic history.

  • This page has been archived and is found on the Internet Archive.
  • Did you misplace your Earth Science Reference Tables?
  • You need to determine the exact time at which Frosty was put into the funnels to melt away, leaving no trace.
  • The activity helps students to understand that long spans of geologic time can be broken down into more manageable segments by using relative ages.

Radioactive Dating Game

In this topic we will focus on long term weather patterns and see how the changing Earth is responsible for creating unique areas of our planet. Earth Science textbooks usually contain exercises covering this topic also. The atom's nucleus is composed of protons and neutrons, which are much more massive than electrons. We will also focus on Earth's interior and how, through the use of seismic data, we have come to understand the different properties of plate tectonics.

Analyses of rock strata and the fossil record provide only relative dates, not an absolute scale. Click here for Absolute Time Fact Sheet. You'll want to cover methods used by scientists to measure absolute time. Radiometric Dating Activity.

Moreover, minerals and rocks are an important first step in understanding other topics in geology that will be discussed later. Here are a few links to help you along the way. Mapping the Earth Mapping the Earth This topic will help you learn the basic skills of reading and interpreting maps.

This is especially helpful in explaining how isochrones work, and why they are so compelling. Using the results of these activities, teachers can then lead students in a discussion of the Law of Superposition and the identification and value of index fossils. Hand this form out to your students along with the matching half-life worksheet.
