ISOLATION OF DNA FROM ONION

Is DNA still present after picking fruit or cooking vegetables? Biology scholars extract and collect DNA strands in an impactful lab. Working groups prepare their samples and compare their results to negative and positive standard...

What a packed lesson! Provide your class with the opportunity to learn about the cell cycle in several exciting ways. Biologists first learn about the theory behind mitosis, then proceed to view onion tips under the microscope and create...

Familiarize young biologists with the inner workings of eukaryotic cells with this vocabulary worksheet. By cutting out and matching a series of definitions and memorization tips to the organelles listed in the provided table, students...

Has your class ever been astounded by the complexity of DNA analysis? Have they ever asked why genetic engineering has become so important to our daily lives? Young scientists perform DNA extraction on strawberries and explore how the...

Three steps are needed to extract DNA from learners' inner cheek cells. The procedure and reasons for each step are explained. As enzymes work on the cells, a series of questions are answered regarding the structure of the DNA molecule....

Uncover the basics of DNA structure through exploration activities. Collaborative groups build DNA models and recreate the process of replication. Then, using plant cells such as peas or strawberries, they extract a DNA sample.

Explore the structure of cell membranes including cholesterol, glycolipids, glycoproteins, phospholipids, and proteins. The video shows and discusses the fluid mosaic model as well as how cell walls differ from cell membranes. 

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.

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 while...

Learners explore DNA. They work in groups and mix prepared detergent/ salt solution, meat tenderizer solution, Fleischman's yeast and water to extract DNA from yeast. Observations are recorded.
