The second unit in the series examines the complex relationships between animals and plants in the whitebark pine community of Waterton-Glacier International Peace Park. In the first of five lessons, scholars mimic Clark’s Nutcracker...

Lesson Planet: Curated OER

#### Climate Change in My Backyard: Grades 10-12, Unit 2

A five-lesson collection examines how current climate changes are different from those in the past. Young scientists gather data from sources life fossils, tree rings, ice cores, and global CO2 levels to determine similarities and...

Lesson Planet: Curated OER

#### What is DBH?

When measuring the circumference of a tree, does it matter how high you place the measuring tape? Most scholars have never considered this question, but scientists know that measurement techniques must be standardized. The 13th lesson...

Lesson Planet: Curated OER

#### What Can Tree Rings Tell Us About Climate?

Tree rings are slightly thicker on the south side of the tree because it receives more sunlight. Part two in a series of five lessons helps learners analyze tree rings to determine the environmental conditions that caused size...

Lesson Planet: Curated OER

#### Historical Climate Cycles

Ice core samples give scientists access to climates of old—those from more than 800,000 years ago. Through an analysis of various temperature graphs from ice cores, tree rings, and weather stations, scholars compare historical climates...

Lesson Planet: Curated OER

#### Branching Out – Exploring Dendrochronology

Tree rings from North America give a continuous history of El Nino intensity over the last 1,100 years. Scholars learn how scientists use tree rings to create timelines demonstrating variations in weather patterns. The cumulative...

Lesson Planet: Curated OER

#### What's The Oldest Tree in the World?

How do you determine the age of a tree without cutting it down? An earth science video presents two possible trees as the oldest, and viewers see they have very little in common. The first appears large and looks almost dead while the...

Lesson Planet: Curated OER

#### It Was a Very Good Year

Waterton-Glacier International Peace Park includes whitebark pines that are over 1,200 years old, meaning they have been there since before medieval times. The second lesson of five details how to read tree rings for climate change and...

Lesson Planet: Curated OER

#### Rings of Life

Individuals analyze tree rings to determine the health of an ecosystem. They then look at otoliths of fish, hard calcium carbonate structures located behind the brain, in the same manner.

Lesson Planet: Curated OER

#### Paleoclimates

How do scientists know what the Earth was like in the past? This second installment of a six-part series focuses on paleoclimates and provides an overview of how geologists determine information about past climates using fossil pollen,...

Lesson Planet: Curated OER

#### Death and Recovery

Mount St. Helens erupted on May 18, 1980, devastating plant and animal life for miles around. Two activities are included in this lesson plan. In one, learners evaluate tree rings to determine the age of a tree and the year of a volcano....

Lesson Planet: Curated OER

#### Dating a Volcanic Eruption

Students discover the various ways in which tree rings can give information. After a brief disucssion of concentric tree rings, they use cross section cut outs of tree rings to identify the time and type of various naturally occuring...

Lesson Planet: Curated OER

#### Tree Rings

Fourth graders explore tree rings. In this plant biology lesson, 4th graders construct a KWL chart on tree rings and examine real tree rings. Students identify the changes that happened during the tree's life and its actual age. Students...

Lesson Planet: Curated OER

#### The Effects of Sunspots on Climate

For this sunspots and climate change learning exercise, learners use a diagram of a tree stump and its rings to determine the age of the tree. They use sunspot data from the internet and they construct an Excel spreadsheet to compare the...

Lesson Planet: Curated OER

#### Tree-Ring Activity

In this tree ring worksheet, students analyze tree ring samples to determine the age of the tree. They compare them to archived samples and answer questions about the age of the tree and its growth years and abnormal growth years.

Lesson Planet: Curated OER

#### How Old Is That Tree?

Fifth graders study environmental changes by examining the annual rings of a cross-section of a tree trunk. They access websites to complete a worksheet on the parts of a tree. They count the annual rings on a tree slice while observing...

Lesson Planet: Curated OER

#### Aging of Trees

Students examine tree rings to determine its age. In this tree ring lesson, students examine core tree samples, identify the tree rings, and then determine its age. Students complete a worksheet, deciding which of the two core sample is...

Lesson Planet: Curated OER

#### Sawing Away

Students examine tree rings. In this tree ring instructional activity, students analyze the rings of fallen trees. Students discuss factors that influence tree growth.

Lesson Planet: Curated OER

#### Logs of Straw: Dendocronology

Students investigate the age of trees by analyzing tree rings. In this dendocronology lesson, students examine sample images of tree rings and identify their age by the amount of rings. Students complete a chart identifying the age,...

Lesson Planet: Curated OER

#### Tree Rings

For this early science tree rings worksheet, students examine 3 sets of tree rings and reveal which one is the oldest based on the number of rings.

Lesson Planet: Curated OER

#### Measuring Absolute Time

In this absolute time worksheet, students answer eleven questions about ways to measure the age of fossils. They define half-life, answer questions about radioactive dating, tree rings and varves.

Lesson Planet: Curated OER

#### How Do We Measure Absolute Time?-Geologic Clocks

In this absolute time instructional activity, students define radiometric dating, tree rings and varves as means to measure absolute time. They are given information about each of these methods of dating.

Lesson Planet: Curated OER

#### Reading Trees: Understanding Dendrochronology

Students examine tree-ring dating and discuss the lack of water the settlers in Jamestown faced. They create paper tree rings, simulate rain patterns, and describe the history of construction paper tree sequences.
