New! DNA Cut and Paste Activity
9th - 11th
Here is a cut and paste activity worksheet designed for older learners. They fill in the blank with information about the composition of DNA, then create a DNA strand with its complimentary nucleotide chain.
Students study Mendelian Laws of Inheritance and differentiate between the different crosses. In this Mendels Law activity students describe DNA replication and genetic engineering.
Genetics: the Study of Inherited Traits
Students explain how genes determine our individual traits. In this biology lesson, students use Mendelian genetics to predict phenotype and genotype. They compare and contrast the role of DNA and RNA.
DNA Blueprint for Life
Did you know that meat tenderizers contain DNA cutting enzimes? Did you know that you can isolate your own DNA? Or the DNA of fruit? Explore with your learners the DNA world with a series of experiments using readily available materials like dish soap, salt, and fruit. Using the provided worksheet, class members record the results of their experiments. The richly detailed resource includes step-by-step directions for the experiments and a vocabulary list.
DNA Extraction Lab
Students extract DNA and test for its presence from unroasted (raw) wheat germ using a prescribed procedure. They modify the procedure to provide a less expensive, easier method. They also extract DNA from different available plant, animal and/or bacterial sources. The yield of DNA will be compared among the sources used.
Extract DNA from a Banana
Your scientists-in-training extract DNA from a banana. Then, they wrap it around a glass rod in order to view the threads of DNA. They draw their observations.
Genetics and DNA
Students describe the structure of DNA and its components and can comprehend that real DNA and its cartoon representation are very different. They are able to link DNA to genetic make-up.
Genetic Markers: Connecting the Dots
Biology buffs simulate how genetic markers are passed among populations in order to understand how these markers can help anthropologists map human migration. A couple of volunteers leave the room while you walk the remaining learners through the simulation. The volunteers come back into the classroom and track what happened based on symbols recorded throughout the simulation. A very visual demonstration of how genes are passed along!
Students explore the basics of DNA and its history. In this DNA lesson students extract DNA from fruits and understand how it is used in forensics.
Genetics DNA Replication
Students explore DNA replication. Beginning with a teacher led discussion, students examine inherited information, genes, and Deoxyribose Nucleic Acid (DNA). As the teacher models the structures of DNA, tells about the contributions of scientists, and explains DNA replication, students take notes. Finally, they draw the structure of DNA and label its parts.
Building on the Past
Students consider how the scientific advances of the past have contributed to the science topics reported on today in the Science Times section. After reading a current science article, they compare and contrast the way science was reported in a previous era.
