Students reinforce their knowledge that DNA is the genetic material for all living things by modeling it using toothpicks and gumdrops that represent the four biochemicals (adenine, thiamine, guanine, and cytosine) that pair with each other in a specific pattern, making a double helix. They investigate specific DNA sequences that code for certain physical characteristics such as eye and hair color. Student teams trade DNA "strands" and de-code the genetic sequences to determine the physical characteristics (phenotype) displayed by the strands (genotype) from other groups. Students extend their knowledge to learn about DNA fingerprinting and recognizing DNA alterations that may result in genetic disorders.

Students perform DNA forensics using food coloring to enhance their understanding of DNA fingerprinting, restriction enzymes, genotyping and DNA gel electrophoresis. They place small drops of different food coloring ("water-based paint") on strips of filter paper and then place one paper strip end in water. As water travels along the paper strips, students observe the pigments that compose the paint decompose into their color components. This is an example of the chromatography concept applied to DNA forensics, with the pigments in the paint that define the color being analogous to DNA fragments of different lengths.

Hank imagines himself breaking into the Hot Pockets factory to steal their secret recipes and instruction manuals in order to help us understand how the processes known as DNA transcription and translation allow our cells to build proteins.

Your body is made of cells -- but how does a single cell know to become part of your nose, instead of your toes? The answer is in your body's instruction book: DNA. Joe Hanson compares DNA to detailed manual for building a person out of cells -- with 46 chapters (chromosomes) and hundreds of thousands of pages covering every part of you.

As a class, students work through an example showing how DNA provides the "recipe" for making our body proteins. They see how the pattern of nucleotide bases (adenine, thymine, guanine, cytosine) forms the double helix ladder shape of DNA, and serves as the code for the steps required to make genes. They also learn some ways that engineers and scientists are applying their understanding of DNA in our world.

In this activity, students learn about the collection and processing of DNA evidence and use DNA profiling to solve a crime. The activity is designed for use on an interactive whiteboard with the whole class, and it can also be used individually or in small groups at a computer or with a data projector and laptop.
By the end of this activity, students should be able to:
describe where DNA is found in the body and how DNA may be ‘left behind’ at a crime scene describe the basic structure of DNA explain the process of DNA profiling
Explore how the code embedded in DNA is translated into a protein. …
Explore how the code embedded in DNA is translated into a protein. Click Transcribe to zoom into the cell nucleus and see the chromosome unravel to expose the strands of DNA. The DNA separates and an mRNA strand is created by matching complementary nucleotides. Click Translate to watch the mRNA leave the nucleus for the cytoplasm and attach to a ribosome. tRNA molecules bring in amino acids and the amino acids are added in the correct order by matching complementary nucleotides. After translation, inspect the protein to see how the amino acid sequence folded.

Students learn how the process of soil solarization is used to pasteurize agricultural fields before planting crops. Soil solarization is a pest control technique in agriculture that uses the sun’s radiation to heat the soil and eliminate unwanted pests that could harm the crops. The approach is compared to other pest control methods such as fumigation and herbicide application, highlighting the respective benefits and drawbacks. In preparation for the associated hands-on activity on soil biosolarization, students learn how changing the variables involved in the solarizing process (such as the tarp material, soil water content and addition of organic matter) impacts the technique’s effectiveness. A PowerPoint® presentation and pre/post-quiz is provided.

In the deepest, darkest parts of the oceans are ecosystems with more diversity than a tropical rainforest. Taking us on a voyage into the ocean -- from the deepest trenches to the remains of the Titanic -- marine biologist David Gallo explores the wonder and beauty of marine life. A quiz, thought provoking question, and links for further study are provided to create a lesson around the 8-minute video. Educators may use the platform to easily "Flip" or create their own lesson for use with their students of any age or level.

Developed for second grade. Students will: use their sense of touch and sight to discover differences between several types of seeds; discuss why seeds come in different shapes and sizes; make connections between art and science; discuss the growth process of a seed; discuss how different seeds are used in different products.Biology In Elementary Schools is a Saint Michael's College student project. The teaching ideas on this page have been found, refined, and developed by students in a college-level course on the teaching of biology at the elementary level. Unless otherwise noted, the lesson plans have been tried at least once by students from our partner schools. This wiki has been established to share ideas about teaching biology in elementary schools. The motivation behind the creation of this page is twofold: 1. to provide an outlet for the teaching ideas of a group of college educators participating in a workshop-style course; 2. to provide a space where anyone else interested in this topic can place their ideas.

In a multi-week experiment, student teams gather biogas data from the mini-anaerobic digesters that they build to break down different types of food waste with microbes. Using plastic soda bottles for the mini-anaerobic digesters and gas measurement devices, they compare methane gas production from decomposing hot dogs, diced vs. whole. They monitor and measure the gas production, then graph and analyze the collected data. Students learn how anaerobic digestion can be used to biorecycle waste (food, poop or yard waste) into valuable resources (nutrients, biogas, energy).

In this video we introduce the digestive system. We look at the two types of digestion: mechanical digestion and chemical digestion. We also look at the two subdivisions of the digestive system: the digestive tracts and the accessory structures.
Lesson 1 in our Digestive System series. This is part of our Anatomy and Physiology lecture series.
