Sometimes science lab can be ... delicious! Middle school science scholars extract DNA from strawberries and other fruits in an engaging lab activity. The teacher's guide includes pacing, materials list, and worksheets with answer keys.

Learners see DNA as a physical building block of organisms and comprehend the basic structure of DNA and the specific components in its structure. They can explain the specific nature of base-pair matching in DNA and that DNA bases form...

Learners create a model of DNA and simulate replication with their models in an activity that uses licorice, colored marshmallows, and toothpicks. Students also label a diagram of replication and indicate major parts of the DNA molecule.

High schoolers complete a study guide using a website which is an animated primer on DNA, genes, and heredity. The Web site is organized around key concepts. The web links and study guide are included.

Transcription means a written copy but how can DNA write a message? The video explains transcription and translation as they relate to DNA and RNA. Then in the interactive, scholars practice base pairing and answer analysis...

Students extract DNA from their own hair roots. They run an electrophoresis gel to examine patterns of their DNA along with standard DNA. The experiment is based on a crime scene scenario.

Students explore DNA restriction mapping. They cut pieces of paper into lengths representing those produced when specific enzymes are used to cut a strand of DNA.

Students discuss DNA Fingerprinting and gel electrophoresis before participating in a crime solving activity. Students simulate their DNA using adding tape and complete the steps necessary to do a gel electrophoresis. They discuss the...

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,...

Students create DNA models. Using puzzle pieces to represent the parts of a DNA strand, they put together a segment of DNA. Once everyone has completed their individual strand, they being linking with other students using tape. Class...

Young scholars extract DNA from green peas. In this DNA extraction lesson plan, students use a blender to chop up peas, they mix them with a little soap, they tenderize them and they mix them with alcohol to see the DNA precipitate...

In this biology worksheet, students identify and label the diagram shown by stating what each part of the diagram represents on the line. Then they use the DNA strand as the original strand and complete the data table. Students also...

In this DNA mutations worksheet, students translate DNA sequences in amino acid sequences and determine if the mutation is harmful or not. This worksheet is a graphic organizer.

Students extract DNA from split peas. In this biology lesson plan, students research how chromatin form into chromosomes. They draw the stages and present their work in class.

Students prepare PowerPoint presentation on DNA and cells. In this biology lesson plan, students create a storyboard of their presentation. They share the finished project in class. 

Students study DNA and its nucleotides. They manipulate paper nucleotides of DNA and investigate how the molecule is produced. Paper versions of sugars, phosphates, and nitrogen bases included.
