In this biology worksheet, students complete 23 short answer questions on bacteria using the information provided. They color and label pictures of bacteria.
Learners examine how traits are passed to offspring.  In this genetic reproduction lesson students develop a model of dna and learn about its structure, replication and function.
Students navigate the National Center for Biological Information (NCBI) website and BLAST program to conduct a variety of biological assignments.
Students predict possible phenotypic and genotypic outcomes for avariety of common plant hybrids. They review and explain the characteristics of dominant and recessive traits and explore Mendelian genetics. Students plot the possible possible outcomes of a designated set of plant hybrid offspring.
Students come to understand that in sexually reproducing organisms, such as humans, typically half of the genes come from each parent. Students examine a fictional pedigree and determine which gene is responsible for a given trait. The genetic information for individuals is depicted as a jigsaw puzzle. Terms that students encounter include gene; chromosome; DNA; pedigree; genotype; phenotype; dominant; and recessive.
In this worksheet, students will answer 4 fill in the blank statements about Mendelian inheritance and meiosis. Then students will use Punnett squares to answer three short answer questions. Students will match 8 genetics vocabulary words to their definitions. Finally, students will fill in 3 short answer questions on gene therapy and cloning.
Tap into writing skills in your science class with this creative writing activity! Get your class to learn the words mitochondria, cytoplasm, chloroplast, chlorophyll, nucleolus, nucleus, tissues, organs, vacuole, and chromosome by writing a brief collaborative story in 25 minutes. This will be a challenge for learners, but could prove to be very engaging!
In this number facts worksheet, students determine the number associated with each of the twenty-five facts provided.  Students then need to determine how the answers are related to each other.  Answers are provided at the end of the worksheet.
In this biology learning exercise, students complete a crossword puzzle with 46 questions on cell structure and function. They identify different cell organelles.
Students study how cancer cells mutate and affect cell division.  In this investigative instructional activity students view a PowerPoint presentation learn the seven warning signs of cancer. 
In this short space, it would be impossible to describe the breadth of this seven-page genetics worksheet. Geared toward AP or college biology learners, they explore not only the basic vocabulary and concepts, but also the Law of Segregation, pleiotropy, epistasis, and the Chromosomal Theory of Inheritance. It was written as a chapter reading guide, but you may want to use it as a note-taking page for a series of lectures on genetic inheritance. 
Parts of the cell as well as genetic material begin this presentation.  As the slides continue, there are explanations of the main terms used in genetics.  The structure of genetic material, chromosomes, and replication are summarized. Next, there are slides explaining dominance, traits, mutation, breeds and crosses.  There is a lot of information given with a good level of detail, making this PowerPoint a great addition to a series of classes or as review.
Ninth graders determine the probability of certain traits by doing a coin toss. In this biology instructional activity, 9th graders differentiate genotypes and phenotypes. They use Punnett squares to predict the characteristics of offspring.
Three steps are needed to extract DNA from learners' inner cheek cells. The procedure and reasons for each step are explained. As enzymes work on the cells, a series of questions are answered regarding the structure of the DNA molecule. As the third step is in process, questions about DNA replication are also addressed. Finally, the DNA strands are placed into tiny tubes and hung on necklaces for biologists to wear home! If you can obtain the tubes, this would be a unique and memorable enrichment.
Given the phenotypes of offspring in mice, flowers, and human blood type, genetics pupils practice determining the genotypes of the parents. Four short answer questions follow. The entire assignment will require learners to put on their thinking caps! Keep this on file as a possible homework assignment for your biology class.
Students view a Power Point and complete activities related to genetic evidence of human evolution. In this molecular evolution instructional activity, students view and discuss a provide presentation. They search for the "tell-tale telomere" and complete a review quiz.
Students practice looking at their genetics to inquire about their past. In groups, they determine their recessive and dominant genes and plot their height on a graph. They compare and contrast the processes of meiosis and mitosis. Individually, they research one genetic disease and share the information with the class to end the lesson.
Students identify the different types of mutation found in the body. In this biology lesson, students differentiate between spontaneous and induced mutations. They discuss germline and somatic mutation.
The main objective of this activity is to illustrate the variation that results from crossing-over during prophase I of meiosis. Other sources of variation from generation to generation are: (1) independent assortment (223 possible gametes that could be formed in humans), and (2) random gamete pairing.
Tenth graders investigate about mitosis, meiosis, and cell differentiation and their purposes and implications in the development and functioning of multicellular organisms. Students use individual journals and a variety of hands-on activities summarized by group discussions.
