Curated OER
Determining Age Of Rocks And Fossils
Students discuss together how to determine the relative age of each of the rock units in the block diagram (Figure 1). After students have decided how to establish the relative age of each rock unit, they should list them under the block.

Determining the Age of Fossils
High schoolers examine the concept of radioactive dating. In this radioactive dating instructional activity, students investigate how to determine the ages of fossils and rocks as they learn about half-life radioactive decay.
Curated OER
Fossil Inferences
Fourth graders use their knowledge about fossils to arrange fossil pictures in sequence from oldest to youngest. They explain how fossils can be used to make inferences about past life, climate, geology, and environments and discover...

How Old Is Mike?
Students examine the absolute dating of fossils, they use a list of names and ages to determine the difference between relative age and absolute age. They explore the relative age and absolute age of people and of fossils.
Curated OER
Law of Superposition
Students define relative dating and describe the law of superposition. They apply their knowledge to construct an accurate geologic time scale. Students examine the importance and function of biotechnology in Earth Science.

Excavating Your Recycling Bin as a Fossil Record
Students explore how scientists examine the past and use rock layers with fossils to understand the past. In this excavation activity students divide into groups and complete an activity.
Curated OER
Assessment & Evaluation
Seventh graders study elapsed time, radioactive decay and half-life. In this time machine lesson students complete several activities and view a presentation.
Curated OER
Favorite Days
Students collect and organize data about themselves. In this data analysis lesson, students discuss their favorite calendar dates and explore ways to display the data.
Curated OER
Examining the Fossil Record
Students create an evolutionary tree based on fossil morphology and their ages. In this fossil record lesson plan, students are given 23 pictures of fossil. They study their morphology and arrange the fossils by age and structures on a...
Curated OER
Understanding the Geologic Timescale
Students identify and analyze how the geologic time scale was developed by investigating 11 periods of time and the vast expanse of time of the Earth's existence. They study their period, determine the important factors indicative to...
Curated OER
Cemetery Geology
Young scholars examine the chemical and physical weathering process of different rocks in a cemetery based on dates on the stones. Students discover the susceptibility of different rock types to weathering.
Curated OER
BOWEN'S REACTION SERIES
Students research Bowen's Reaction Series and recreate the process in an experiment which details the crystallization sequence of minerals that can be observed in nature.
Curated OER
Density And Volume
Sixth graders explore the concept of density as a relationship of an object's mass to its volume. Densities of a variety of objects are compared and used to identify an unknown object.
Curated OER
Sound
Students identify sources and importance of sound, discuss sounds heard on way to school, explain why sound waves can be "seen", and participate in various classroom activities and experiments that illustrate how sound travels.
Curated OER
Sink or Float?
Students examine how weight and balance can effect if an item sinks or floats. They listen to the book "Who Sank the Boat?" by Pamela Allen, and discuss how the smallest animal sank the boat. Students then conduct an experiment in...

A “Salting” Solution
Ninth graders investigate the factors affecting solubility. In this chemistry lesson, 9th graders differentiate solvent and solute. They give examples of real world application of solutions.
