Students are introduced to tree structure and use. They identify their special tree using all senses except sight. Students identify six different internal parts within a cross section of tree trunk (bark, phloem, xylem, cambium,...

Students do an experiment using a microscope. In this lesson, about cells, students examine different slides using a microscope. Students look at an onion skin, cheek cells, and potato cells. In each of these, students find cell walls,...

In this cell fluid balance learning exercise, students read about how fluids are transported in and out of a cell through the cellular membrane. Students compare cells that are isotonic, hypertonic, and hypotonic. This learning exercise...

Student explore cancer, its causes, and various types. Students research compare/contrast a health cell to a cancer cell. They compare treatments available for childhood cancers.

Students explain the roles of mRNA, tRNA and ribosomes. They explain how mutations can occur in an individual. Students simulate parts of a cell to access about the process of protein synthesis.

Students study how Alzheimer's affects different parts of the brain, sketch a healthy neuron and its parts, and diagram brain changes during the early and late stages of Alzheimer's.

Learners identify the purpose of cellular mitosis. They work in groups of four to use images of animal and plant cell mitosis to illustrate each step in the mitosis process on their graphic organizer.

Pupils apply skills they have learned to construct an accurate model of the Brassica and then work together on a group project. They analyze how the parts of a system go together, and how these parts depend on each other. Finally,...

In this brain learning exercise, students describe three jobs of the brain, draw a picture of a neuron and label its parts, and determine what to do to keep the brain healthy. This learning exercise has 1 drawing and 2 short answer...

In this circulatory system worksheet, students review the functions of red blood cells, white blood cells, and platelets. Students label the parts of a human heart on a diagram. This worksheet has 4 short answer, 13 matching, and 9 true...

Learners identify the parts of the egg and observe the composition of the egg parts.

In this nervous tissue worksheet, students list and describe the functions of the nervous system and its two principle parts. Then they list and give the function and location of the six types of glial cells. Students also describe two...

In this blood worksheet, students review what makes up blood: plasma, platelets, and red and white blood cells. Students also learn how the blood helps fight viruses, bacteria, and other foreign substances. This worksheet has 10 fill in...

Students investigate and then build neurons in this lesson. They are examined as key parts of the brain and nervous system and seen as different from normal cells.

Students investigate how water passes through cell membranes. In this biology lesson, students differentiate osmosis and diffusion. They illustrate the movement of water in both processes.

Learners investigate how trees produce their own food. They examine chlorophyll cells with a microscope, analyze a cross section of a log, determine how old the tree was, simulate the distance of the roots, and create a play.

Students explore reflexes. In this biology lesson plan, students discover the basic facts about the reflex systems of the brain as they take part in hands-on activities.

Fifth graders study the parts of a plant, their life cycles, and how to care for them in this unit.

Students observe organisms found in pond water with a microscope. In groups, they discuss how single-celled organisms satisfy their needs for food, water and air. They compare and contrast the needs of macroscopic and microscopic...

Students explore genetics. They discuss how chromosomes and/or genes are regulated during the life of an organism. In a lab setting, students compare and contrast the genomic regulation of prokaryotic and eukaryotic cells using...

In this paramecium worksheet, students sharpen their science skills as they color the parts of a paramecium according to the instructions and then respond to 15 analysis questions.

In this ionic compounds worksheet, students identify the number of electrons gained or lost in ions, they show that transfer of electrons in ionic compounds and they write balanced ionic compounds given ions. They answer 4 questions...

In this biology worksheet, students complete a crossword puzzle with 28 questions about fungi. They identify the different parts of a fungus.

Learners identify the different parts of the circulatory system and their function. They work together to create their own model of the system and use it to determine the rate of blood flow. They answer questions related to their model.
