Absolute dating activity answers, radioactive dating game

This will enable your teacher to quickly check whether you have the correct sequence. We will also focus on agents of erosion and be able to identify their different geologic features. Moreover, minerals and rocks are an important first step in understanding other topics in geology that will be discussed later. Books with interactive features may work best on an iPad.

We will also focus on how major extinction periods throughout geologic history have changed the development of life on Earth. In the second part of the activity, students progress to dating rock layers by sequencing fossils found in the different strata. We will focus on the heliocentric model and learn about how Earth fits into the Solar System, Galaxy and Universe. We will also focus on earthquakes and how we use seismic waves to locate their epicenters.

Absolute Dating

We will focus on minerals and how they are the building blocks of rocks and we will show how we can no longer live without these resources. In this topic we will learn about the beginnings of Earth and the extreme changes it has undergone. Multi-touch books can be read with iBooks on your Mac or iPad. The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages.

By using this information from rock formations in various parts of the world and correlating the studies, scientists have been able to establish the geologic time scale. In order to align this activity more closely to this practice, teachers should require students to explain and justify each step of their timeline. Specific rock formations are indicative of a particular type of environment existing when the rock was being formed. Students should have some prior knowledge of rocks and how they are dated. Graphs, charts, and images can be used to identify patterns in data.

  1. The activity helps students to understand that long spans of geologic time can be broken down into more manageable segments by using relative ages.
  2. Both parts of the activity can be completed in one class period.
  3. 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.
  4. Once this info is calculated, students create a graph comparing the class average of parent isotopes to the number of half-lives.
  5. In the first part of the activity, students are asked to sequence cards by identifying and ordering overlapping letters found on the cards.

We will place emphasis on the different types of volcanoes around the world and the potential hazards that they impose on mankind. From its early formation to present, Earth has undergone extreme changes and evolved to be one of the most unique planets in our solar system. Students will be able to explain what a half-life of a rock is. Analyze and interpret data to provide evidence for phenomena. Once students are in their groups, with supplies, and general directions are given, they are on their own for doing their runs.

In this topic we will learn about the beginnings of Earth. 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. By correlating fossils from various parts of the world, scientists are able to give relative ages to particular strata.

Analyses of rock strata and the fossil record provide only relative dates, not an absolute scale. This is called relative dating. Scientific measurements such as radiometric dating use the natural radioactivity of certain elements found in rocks to help determine their age.

Mapping the Earth

Teaching about Earth's history is a challenge for all teachers. 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. All of the fossils represented would be found in sedimentary rocks of marine origin.


It focuses on the worldwide coordinate system of latitude and longitude and applies that to more detailed topographic maps used by geologists and other earth scientists. Time, space, and energy phenomena can be observed at various scales using models to study systems that are too large or too small. In addition, students should discuss which, if any, of the fossils in a particular segment could be utilized as an index fossil.

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. Time factors of millions and billions of years is difficult even for adults to comprehend. This topic will help you learn the basic skills of reading and interpreting maps. We will also focus on Earth's interior and how, through the use of seismic data, dating a young we have come to understand the different properties of plate tectonics.

Students should recognize each time the number should go down by appx half. Daughter isotopes are represented by the M side down stable. They not only enjoyed this activity, but they really gained a better understanding of it as well.

Regents Countdown

As we move throughout the year, we will revisit these concepts and apply our knowledge to specific topics. Students graph, post questions, and data table will be looked at. Locally, physical characteristics of rocks can be compared and correlated. We will focus on different types of weather patterns and see why certain regions have different atmospheric conditions.

Radioactive Dating Looking at Half-Lives Using M&Ms

Learning Goals

In this activity, students gain a better understanding of radioactive dating and half-lives. This activity would also be easy to adapt when talking about half-lives within a chemistry course. Only one sequence is correct for each activity, but the answer is easily achievable if students can recognize the relationships detailed in the cards. Once these answers are shared and evaluated, students would be prepared for a discussion of the Law of Superposition.


Use this information to sequence the cards in a vertical stack of fossils in rock strata. In this topic we will take a look at how the Theory of Plate Tectonics developed and provide concrete evidence that support the theory. By matching partial sequences, the truly oldest layers with fossils can be worked out.

Hawaiian Rainfall Patterns. Moreover, we will focus in on the Greenhouse Effect and Global Warming and relate it to climate patterns. Students will understand how scientists use half-lives to date the age of rocks.

Summary In this activity, students gain a better understanding of radioactive dating and half-lives. Moreover, this chapter will revisit sedimentary rocks and see how the sediments produced during weathering factor into the formation of the different rocks. Then students take the class data and create a graph comparing the number of parent isotopes to the number of half-lives.

Radioactive Dating Looking at Half-Lives Using M&Ms

We will also focus on the different agents of erosion and be able to identify the geologic features that each of them create over time. This would also mean that fossils found in the deepest layer of rocks in an area would represent the oldest forms of life in that particular rock formation. Below are some additional resources to help you along the way, prepare you for your midterm exam and the Earth Science Regents exam. Each card represents a particular rock layer with a collection of fossils that are found in that particular rock stratum. Science and Engineering Practices.

If certain fossils are typically found only in a particular rock unit and are found in many places worldwide, they may be useful as index or guide fossils in determining the age of undated strata. This topic will help you learn about Earth's true shape, online free the different spheres in and around Earth and interpreting various types of maps. Students will have a more in-depth understanding of what radioactive decay is. Sequence the remaining cards by using the same process.

Context for Use
  • New information needed to be introduced with parent and daughter isotopes.
  • Parent isotopes are represented by the M side up radioactive.

Welcome to Earth Science

Mr. Leigh-Manuell s Earth Science Class

Did you misplace your Earth Science Reference Tables? It focuses on latitude and longitude and applies that to more detailed topographic maps used by geologists and other earth scientists. Find a rock layer that has at least one of the fossils you found in the oldest rock layer. In this topic we look at the beginnings of astronomy and see how technology has allowed mankind to gain a better understanding of our Universe. Once this is done, accuracy range of carbon students have some post questions they are given that they should record in their science notebook.
