Take your advanced biology learners across the great divide: where cells divide, that is! Although it was created as a chapter reading guide, having your class complete this worksheet is not only appropriate, but also highly valuable in...

Students plant seeds in order to investigate and explore the questions: "How do seed companies develop varieties of plants?" and "What is the ideal plant?" Students will study related vocabulary and sketch seeds as they emerge. Students...

Compare and contrast eukaryotes, prokaryotes, and viruses with a chart and a Venn diagram. Beginning microbiologists consider motility, reproductive ability, DNA content, and the presence of organelles. They write short answers to...

For this meiosis worksheet, high schoolers read about the phases of meiosis I and meiosis II and simulate the chromosomes and chromatids in each phase. Students draw the changes in each phase and produce 4 cells with half the DNA in the...

In this chromosomes worksheet, students understand the make up of a DNA molecule and compare the different ways chromosomes are connected. This worksheet has 35 fill in the blank questions and 6 drawings.

In this DNA: structure and replication worksheet, learners fill in the blanks about the structure of DNA and replication of DNA. Students sketch several diagrams of DNA at different stages.

Learners interact with a video to explore the basis for the science of chromosomes. They perform a chromosomal analysis called a karyotype and explore how seemingly minute errors in chromosomes can lead to devastating illnesses.

In this cloning activity, learners fill in the blank with information researched about cloning. Students draw a labeled sketch and complete statements for each step of cloning displayed in the noted text.

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...

Students develop understanding of DNA by modeling the process of DNA extraction. They study DNA, genes and chromosomes. After the basic information, students do an experiment in which they separate out DNA from peas.

In this meiosis instructional activity, student complete the blanks describing the process of meiosis. Students draw a diagram of homologous chromosomes.

In this DNA worksheet, students read information about DNA and messenger RNA. Then students complete 16 short answer questions and color 2 images.

Students study the Human Genome Project and participate in a debate about the project. In this genome lesson, students review the terms related to the genome project, take a poll about the ethical issues of the project, and watch a video...

Students explore DNA microarrays. In this genetics lesson, students model DNA microarrays that are used by scientists. Students work to determine levels of breast cancer genes in patients. They will determine the treatment required based...

In this cell cycle activity, students fill in the blank with information about the cycle of a cell. Students sketch several drawings of different phases in the cell cycle.

Students explore the concept of extinction by studying dinosaurs. In this dinosaur lesson, students distinguish between extinct creatures and those that still exist.

Students develop an understanding of how innate and learned behaviors and the environment determine behavior. They see how a variety of factors affects our pet's behavior-including species-specific traits, the environment, training, and...

Students explore human behavior by participating in a class science game. In this human characteristics activity, students identify different human traits that are passed down by each generation and the purpose each of them have....

For this literacy worksheet, students find the words that are in the word search puzzle that focus upon the vocabulary that is from the theme of the sheet.

Learn about DNA and decoding the human genome by clicking graphical DNA models. You can also review a timeline that shows important moments in human genetics research. In Spanish.
