Students engage in a variety of activities designed to facilitate the understanding of DNA. Activities include preparing human chromosome spreads, separating a mixture of dyes using gel electrophoresis and extracting DNA from onion cells,

Students extract DNA from an onion using household equipment and supplies.

In this DNA instructional activity, students examine a sequence of DNA of a fictitious species. They determine the traits the species has given amino acids sequences and chart of traits that each amino acid sequence indicates. Students...

Students work cooperatively in pairing chromosomes, created statistical genetic babies using the face lab, constructed a color DNA booklet and demonstrated mitosis in a flip book.

High schoolers build DNA strands and practice base pairing rules using an interactive website in this technology-based lesson for a high school science class. This lesson includes links to the interactive website, a worksheet, and a...

Students examine the principles of electrophoresis. They evaluate both the agarose and polyacrylamide system of molecular separation. In order to bring the concepts of genetics and evolution full circle from DNA to protein, students...

The many slides and images in this PowerPoint are clear and relevant to the detailed content covering the details of DNA structure, replication, cell differentiation, and mutation on an advanced level. The slideshow summarizes all of the...

In this cell activity students review processes of cells. Students recall terms associated with cell division. Students label and explain phases of mitosis.

From crime to paternity, DNA fingerprinting has revolutionized how the world views inherited traits. Science sleuths investigate the facts about DNA profiling through a variety of activities. The Teacher's Guide includes printable...

When it comes to the origin of the human species students are full of misconceptions. Clear up the hominid confusion with this evolutionary activity focused on assisting students in understanding prehistoric man and his family tree....

Can you describe a gamete without using the words sperm or egg? Scholars play a vocabulary review game where they try to get other players to guess their words. Each card has the target word as well as two related words they must not...

At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

Help your students understand cell division. Explore the topics of mitosis by examining the details of chromosomes at interphase, metaphase, anaphase, prophase, and telophase. Wonderful slides will keep your students' attention...

The concepts here cover the gamut of biotechnological engineering. Information is given about plasmids and genetic manipulation. After reviewing genetic engineering, this slide show would be useful to recap some of the main procedures.

A 17-page practice final exam for a college-level introductory biology course is contained in this resource. Matching and short answer questions cover every topic that you would expect to teach during an advanced biology course including...

Reward biology learners for working hard in their mitosis lesson with a sweet snack at the end! They begin by twisting apart creme-filled cookies and using the icing as a cytoplasm. Colored candy sprinkles make up chromosome pairs,...

Students plant seeds in order to investigate and explore the questions: "How do seed companies develop varieties of plants?" and "What is the ideal plant?" Students will study related vocabulary and sketch seeds as they emerge. Students...

Learners study how cancer cells mutate and affect cell division.  In this investigative lesson students view a PowerPoint presentation learn the seven warning signs of cancer. 

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...

Seventh graders describe the processes involved in mitosis and meiosis. For this life science lesson, 7th graders create chromosome models using strings and beads. They play a jeopardy team game at the end of the unit to review concepts...

Students develop an understanding of the role both nature and nurture play in determining an individual's traits. Using a website, students answer questions about nature and nurture in order to solve the riddle, What do you call a smart...

Based on current scientific knowledge, all cells come from preexisting cells. Scholars learn about cell division, cell replication, mitosis, meiosis, and more with a PowerPoint. It describes the differences between prokaryotes and...

Compare and contrast eukaryotes, prokaryotes, and viruses with a chart and a Venn diagram. Beginning microbiologists consider motility, reproductive ability, DNA content, and the presence of organelles. They write short answers to...

In this meiosis worksheet, students read about the phases of meiosis I and meiosis II and simulate the chromosomes and chromatids in each phase. Students draw the changes in each phase and produce 4 cells with half the DNA in the end.
