Parts of a Flower! Flower Dissection
Sometimes the best way to learn about plants is to see the different parts of a plant yourself. Groups of learners dissect flowers to answer questions about what they observe and what they wonder about their flower.

Annelids: The Segmented Worms
Here's a lesson that just might make your class squirm! Learn about segmented worms in a detailed PowerPoint presentation including the wriggly earthworms young scientists dig up in their backyards. Although seemingly simple creatures,...

LP 6--8: Xenopus laevis (frog) Development for a 7th Grade Audience
Seventh graders view lab stations with Xenopus at different stages of development. They identify the life stage of the sample, as well as the previous and next stages. Students must explain their reason for selecting the specific stage.

Fruit Fly Ranch Activity
Seventh graders describe how the traits of an organism are passed from generation to generation. They distinguish between asexual and sexul reproduction. Students identify traits through genes and those resulting from interactions with...
Curated OER
Pollination Power
Students go out into the garden and observe pollinating animals through hand lenses. In this pollination lesson plan, students also discuss how animals carry seeds to create new plants elsewhere.
Curated OER
Karyotype Puzzle
Young scholars identify chromosome pairs based upon band patterns and location of centromere. They order chromosome pairs based upon size. Students differentiate normal karyotypes from abnormal karyotypes. They correctly record karyotype...

Genetics: Knowledge Quiz
In this genetics quiz worksheet, students complete a set of 10 multiple choice questions covering various concepts of genetics. A reference web site is given for additional resources.
Curated OER
Ferns and Gymnosperms
In this fern and gymnosperm worksheet, students will read about two types of vascular tissue: xylem and phloem. Then students will read about the difference between sporophytes and gametophytes. Using this information students will...

Comparing Ovaries And Testes
In this reproductive system learning exercise, students compare specimens of rat ovaries and testes. They complete 5 short answer pre-lab questions, follow an 11 step procedure and answer 5 analysis questions.

Meiosis and Sexual Reproduction
Eighth graders are able to define meiosis. They are able to compare and contrast meiosis and mitosis. Students are able to state the phases of meiosis. They complete a K-W-L chart on meiosis and mitosis. Students talk about meiosis...

In Vitro Fertilization
A possible option for infertile couples is in-vitro fertilization and implantation. Through this two-part lesson, the class learns about this process by teacher lecture and internet research. A case study is given to read as a take-home...

Buzzy, Buzzy Bee
Learners simulate honeybees pollinating flowers. In this pollination lesson, students role-play the process of pollination over the course of several seasons. Learners graph results and share their graphs with the class.

How Do Organisms Reproduce
Middle schoolers examine the difference between mitosis and meiosis, and describe the steps involved in meiosis and the significance of each step. They create a diploid nucleus containing two pairs of chromosomes using clay.

Embryology as Evidence of Evolution
Students observe the two major developmental pathways (protostome and deuterostome). They analyze data regarding differences in nucleotide sequences and construct a phylogenetic tree. They observe the similar evolutionary history shared...
Curated OER
An Inventory of My Traits
Students take an inventory of their own easily-observable genetic traits and
compare those inventories with other students in groups. They then make
data tables and bar graphs showing the most and least common traits in their group.
Curated OER
An Inventory of My Traits
In this biology activity, students identify and describe a number of easily observable genetic traits and compare the traits they have with other students. Then they identify and describe that some traits are common while others are not...
Curated OER
Flower Power
Students explore the parts of flowers and how they reproduce. They dissect flowers and observe the reproductive organs. Students observe anthers and ovaries of Tiger Lilies under a microscope. They investigate how insects and other...
