Relative dating lab activity, activity 7 relative dating

Analyze and interpret data to provide evidence for phenomena. Mapping the Earth Mapping the Earth This topic will help you learn the basic skills of reading and interpreting maps. 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 focus on different types of weather patterns and see why certain regions have different atmospheric conditions.

  • 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.
  • For example, students should discuss which fossils are making their first appearance in a particular segment and which fossils have disappeared.
  • Sequencing the rock layers will show students how paleontologists use fossils to give relative dates to rock strata.
  • 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.

Activity 7 Relative Dating

Moreover, minerals and rocks are an important first step in understanding other topics in geology that will be discussed later. By correlating fossils from various parts of the world, scientists are able to give relative ages to particular strata. 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.

Scientific measurements such as radiometric dating use the natural radioactivity of certain elements found in rocks to help determine their age. Both parts of the activity can be completed in one class period. As we move throughout the year, we will revisit these concepts and apply our knowledge to specific topics. 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. We will focus on the heliocentric model and learn about how Earth fits into the Solar System, Galaxy and Universe.

For example, most limestones represent marine environments, whereas, sandstones with ripple marks might indicate a shoreline habitat or a riverbed. 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. In this topic we will take a look at how the Theory of Plate Tectonics developed and provide concrete evidence that support the theory.


Once these answers are shared and evaluated, students would be prepared for a discussion of the Law of Superposition. Time factors of millions and billions of years is difficult even for adults to comprehend. In this chapter, we will discover the relationships between weather variables and see how a change in one can affect a change in another.

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. Using the results of these activities, lanka sri teachers can then lead students in a discussion of the Law of Superposition and the identification and value of index fossils. We will also focus on how major extinction periods throughout geologic history have changed the development of life on Earth. This topic looks at minerals and rocks and helps us to understand the different properties needed to identify them.

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. This will enable your teacher to quickly check whether you have the correct sequence. In this topic we will learn about the beginnings of Earth.

In addition, students should discuss which, if any, of the fossils in a particular segment could be utilized as an index fossil. Graphs, charts, and images can be used to identify patterns in data. Specific rock formations are indicative of a particular type of environment existing when the rock was being formed. Scientists also use direct evidence from observations of the rock layers themselves to help determine the relative age of rock layers.

In order to align this activity more closely to this practice, teachers should require students to explain and justify each step of their timeline. In this course you will be studying the different processes, relationships, mechanisms, and concepts that help us interpret our planet Earth. Locally, physical characteristics of rocks can be compared and correlated. We will also focus on earthquakes and how we use seismic waves to locate their epicenters. Only one sequence is correct for each activity, but the answer is easily achievable if students can recognize the relationships detailed in the cards.

Mapping the Earth

In this topic we will look at surface processes and the mechanisms that help shape our planet Earth. All of the fossils represented would be found in sedimentary rocks of marine origin. Multi-touch books can be read with iBooks on your Mac or iPad. 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.

  1. In this topic we will learn about the beginnings of Earth and the extreme changes it has undergone.
  2. Time, space, and energy phenomena can be observed at various scales using models to study systems that are too large or too small.
  3. The major difficulty that students may encounter is the concept that extinction is forever.

The activity helps students to understand that long spans of geologic time can be broken down into more manageable segments by using relative ages. Analyses of rock strata and the fossil record provide only relative dates, not an absolute scale. This is called relative dating. In the second part of the activity, students progress to dating rock layers by sequencing fossils found in the different strata.

Activity 7 Relative Dating

Earth Science Lab Relative Dating 2 Answer Key - The Earth Images

Welcome to Earth Science

Books with interactive features may work best on an iPad. It focuses on latitude and longitude and applies that to more detailed topographic maps used by geologists and other earth scientists. This topic will help you learn about Earth's true shape, the different spheres in and around Earth and interpreting various types of maps. Well don't worry, bad online dating messages click below to download your copy.

Mr. Leigh-Manuell s Earth Science Class

Keep in mind that extinction is forever. 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. Again, this exercise is only hypothetical but the experience provided to students can be transferred to actual rock data. Here are a few links to help you along the way. This topic will help you learn the basic skills of reading and interpreting maps.

Regents Countdown

Below are some additional resources to help you along the way, prepare you for your midterm exam and the Earth Science Regents exam. Moreover, this chapter will revisit sedimentary rocks and see how the sediments produced during weathering factor into the formation of the different rocks. We will also focus on agents of erosion and be able to identify their different geologic features. Sequence the remaining cards by using the same process. Did you misplace your Earth Science Reference Tables?


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. By matching partial sequences, the truly oldest layers with fossils can be worked out. 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. Hawaiian Rainfall Patterns. By using this information from rock formations in various parts of the world and correlating the studies, does how scientists have been able to establish the geologic time scale.

Moreover, we will focus in on the Greenhouse Effect and Global Warming and relate it to climate patterns. On a larger scale, even between continents, fossil evidence can help in correlating rock layers. Use this information to sequence the cards in a vertical stack of fossils in rock strata. This also means that fossils found in the lowest levels in a sequence of layered rocks represent the oldest record of life there.
