Students explore the four stages of mitosis. They view a prepared slide of an onion root tip undergoing mitosis to identify the stage for each cell in view. They record the number of cells in each stage, graph the results, then calcualte...

Students study DNA by isolating it from plant tissue. They determine the purpose of each step in the isolation procedure as it relates to the physical and biochemical characteristics of the genetic material

In this DNA extraction learning exercise, students learn how to extract DNA from various foods. Students complete 2 short answer questions.

Students become familiarized with use of the microscope.

Learners distinguish the differences between Prokaryotic and Eukaryotic cells. Using microscopes, they examine a variety of plant and animal cells. Working in groups, they draw and label plant and animal cells and show the mathematical...

Tenth graders examine the process of mitosis on a laser disc. They examine mitosis in an onion utilizing the microscope.

Students will explore cells to understand that all living things are composed of cells. In this science lesson, students use the scientific process and work in cooperative groups to gain a better...

Students do an experiment using a microscope. In this lesson, about cells, students examine different slides using a microscope. Students look at an onion skin, cheek cells, and potato cells. In each of these, students find cell walls,...

Students define biotechnology and discuss the economic impact of biotechnology. They also describe what a 1015 onion and a slow-softening tomato are and how they are produced. They examine the safety of genetically-engineered or altered...

Preparing the root tip samples is the most challenging part of the mitosis-viewing lab found here, but the directions help ensure you have everything you need. There is no worksheet included; however, there is a sample data table....

Mr. Bergman has been murdered and we need you to solve the crime! The cross-curricular unit covers 11 different types of forensic science and includes 17 activities. Scholars perform blood type analysis, blood spatter analysis,...

An article relaying vital information about health and nutrition are the backbone of this lesson on eating the right foods. A series of activities are used to help upper graders understand the science supporting our understanding of what...

Students 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 through the...

Students examine living and non-living things. In this life science instructional activity, students are given a group of objects and discuss if they are living or non-living. Students identify and list characteristics of living things.

Students cut out the nucleotide models and have an opportunity to relax and chat. Using imagination, students pretend to be molecules acting out protein synthesis and whole body movement.

Students investigate the characteristics of living things. For this life science lesson, students examine several living and non-living specimens. Students determine which things are living and non-living.

Learners close their eyes and taste foods without using the sense of sight to identify the foods. They record what they think the food is that they tasted.

For this homonym worksheet, students complete 20 multiple choice questions, selecting the correct homonym to complete a sentence. Students may click on an answer button for immediate feedback.

Students, working in cooperative groups, extract very impure samples of DNA from a number of tissue samples. They determine how the samples can be preserved and how they are similar.

Students review vegetables and their nutrient values and production. In this vegetable production worksheet, students read information about the nutrients in vegetables and how they are grown. Students participate in a game of Twister to...

Third graders experiment with common grass and cellular division.

Students taste foods, some of which are familiar foods and some of which are uncommon foods. They compare and contrast the tastes and graph their likes and dislikes.

In this project, you'll learn how to isolate DNA from onion cells, separating it from other cellular components in a manner that still preserves its structure and sequence. In the end, you'll have enough DNA to see with the unaided eye,...

In this activity, middle schoolers make microscopic observations of onion root tips, discuss them with classmates, then make detailed drawings that are shared.
