Students examine the transportation system of a tree and the speed with which nutrients and water move. Cross sections of the samples used are examined in class for experimental results.

Students research tree leaves. In this tree leaves activity, students observe, measure, and sort tree leaves. Students examine leaves individually, in groups, and in relationship to the entire tree.

First graders explore concept of interdependence through production of the play, The Great Cedar Tree.

Students use examples of Joseph Raffael's art of nature to create an all-school mosaic of a tree in spring using clay.

Fourth graders investigate the concept of forestry and how trees are used for different purposes. The problem of deforestation is presented in this historical instructional activity. The comparison of our society to others that depend on...

Sixth graders identify trees by observing their structure and shape. They particiapte in taking pictures of trees with a digital camera and using these pictures in an electronic presentation where they creat a database with this...

Seventh graders develop an experiment to measure the temperature on several parts of a tree to determine if there is a difference in surface temperature. They practice the process of scientific method to find out if trees create heat in...

In this Did You Know worksheet, students complete the sentence, "Did you know..." by writing about trees. They are given pictures of two different types of tree to write about.

Eleventh graders compare the amount of sugar sand present in tree sap. For this environmental science lesson, 11th graders measure different tree circumference. They prepare a report and share findings in class.

In this animal maze, students follow a number of paths each of which begins with the picture of an animal such as bear, beaver, porcupine, or a deer. They follow 4 different paths to determine which animal gnawed on the tree that is...

In this animal maze worksheet, students attempt to determine which of the four animals that are pictured on the page made the scratches on the tree at the end of the maze. They see a four large mammals.

Students read a story and solve a problem about an unhealthy population of trees.  In this forest lesson plan students study tree disease and then research it online and present what they found. 

In this flowering plants worksheet, students compare the structure and function of a tree trunk and a leaf. This worksheet has 1 true or false and 5 fill in the blank questions.

In this senses worksheet, students draw what they observe with each of their senses. Students draw 5 pictures under the five senses given.

Students explore plant biology by conducting a light sensitivity experiment in class. In this wintergreen tree lesson, students discuss how specific species of trees can grow in the dead of winter by identifying the amount of light that...

Students sort tree leaves. For this plant biology lesson, students collect leaves and group them according to size, shape, and color. Students discuss their observations.

Students observe and measure tree leaves.  In this leaf instructional activity students do on a "leaf walk" then use the leaves they find to complete a few activities. 

In this leaves worksheet, students color the leaves and draw the veins to identify the trees around them. Students do this for 12 leaves.

Students observe trees in their schoolyard and record the seasonal changes by drawing pictures. For this ongoing lesson, they discover the names of the seasons and place green paper leaves on a paper tree in the classroom, which are also...

Students use a core map to obtain information about the Big Trees for measuring and graphing. In addition, students judge whether the Big Trees should be preserved or conserved.

Learners gain an understanding of the science of taxonomy and how it is used in classifications. They use an identification key and construct a key of their own. They identify tagged trees on the school property with their lab group...

Students examine the cause and effect of deforestation and investigate possible solutions. They read and discuss an article, write an essay, and conduct research for a project involving a forest management interview, or analyzing uses of...

Fourth graders describe the various kinds of soils and how plants and animals are affected by them. They describe the baic needs of plants, scoring at least a 3 or 4 on a 4-point rubic. Students are able to predict and/or infer what...

Ancient coral beds give scientists clues to past ocean temperatures in much the same way that tree rings indicate historical weather conditions. High school scientists examine coral oxygen isotope ratios and plot the data as a function...
