A terrific WebQuest is outlined here for your young scientists. They will learn about how proteins are made by following the instructions given to them from genes. Before the WebQuest begins, there are some terrific "front loading" activities and worksheets present in the plan. The WebQuest is easy to follow, and the culminating activity is quite good. A very fine middle to high school biology lesson plan.
Geneticists manipulate Punnett squares to determine the patterns of dominant and recessive gene influence on first and second generations of humans and plants. The technology-based lesson plan employs a variety of media for exploring heredity and is ideal for the middle school life science classroom.
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 gene cloning worksheet, students are given a gene sequence of DNA, plasmid DNA, 3 restriction enzymes, their cut patterns and a DNA ligase. They answer 6 questions about the results of using different restriction enzymes to cut the gene sequence and how they would go about inserting the gene into the plasmid DNA.
Students explore genes and inheritance. After listening to a story describing a rare genetic disease, students discuss inheritance and how living things pass on traits to their children. In groups students, students decipher code problems, draw each problem, and predict what would happen if the codes were changed.
High schoolers explore DNA microarrays. In this genetics lesson plan, students model DNA microarrays that are used by scientists. High schoolers work to determine levels of breast cancer genes in patients. They will determine the treatment required based on their findings.
Students are introduced to genetics along with genetic diseases and heredity. In groups, they complete a Punnett Square to determine the dominant and recessive genes. After viewing diagrams, they identify the characteristics of DNA and demonstrate the processes of Meiosis and Mitosis. To end the lesson, they discover the factors that cause genes to mutate.
Ninth graders use this activity to simulate the sequencing of gene and to detect the presence of possible genetic defects. They use diagrams that represent bands of nucleotides in order to determine the sequence of a small piece of the CF gene. Students make comparisons between base sequences of pairs of chromosomes from individuals who are not affected by CF and those who are.
Covering the molecular interactions involved with DNA packing and the control of gene activity in depth, this slideshow is useful for higher-level biology students. The biochemical components of protein translation are diagrammed and labeled, and will be much clearer when the are displayed in this manner.
Students research the population of Bengal tigers and their existence as either dominant or recessive. They explore the presence of fur on these tigers and its lethal combinations. Determinating the effect of random mating in a population of tigers possessing a recessive gene.
Background reading is available in the first two pages of this worksheet, along with reading comprehension questions and a laboratory activity in which students use mircroarray technology to identify genes used in cell differentiation. This is a comprehensive college-level genetics assignment that will require more than one session to complete.
Imagine a pair of dragons that produce offspring and determine the percentage of the hatchlings have wings and large antlers. This fantastic activity draws genetics learners in, introduces them to alleles, meiosis, phenotypes, genotypes, and teaches them how to use Punnett squares. The exercises also illustrate the law of independent assortment and linked genes. The handout is ten pages long and will take days to work through, but it will definitely keep learners engaged!
Juvenile geneticists will jive with this imaginative investigation of inheritance in dragons. Six pages begin with a detailed introduction to meiosis and homologous chromosome pairs. Instructions guide learners through a simulation in which they draw craft sticks marked with autosomes in order to decode the genes inherited by the baby dragon. An organized chart is provided, along with critical thinking questions and a partially drawn dragon on which learners will add the inherited traits. This is a gem of a worksheet!
