Curated OER
Extracting DNA from Your Cells
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....
Curated OER
Comparing Animal and Plant Cell Structure
Students work as a team to use the ProScope Digital USB Microscope and a computer to collect microscopic images from a variety of organisms. When they compare these specimens, they are able to determine how they are alike and different...
Curated OER
What's Outside the Cell Membrane ?
Students examine the cell coats (matrix) of chondrocytes and fibroblasts and observe these cells actively exclude particles which are released around them. They observe the function of the cell membrane as a gatekeeper as it prevents...
Curated OER
Seeing Cells
Students discuss what comes to mind when they hear the term cell and discuss what a cell is in biological terms. They look at pictures of cells and color a picture of a cell diagram, writing the job of each part as they go. After the...
Curated OER
Use of Microscopes and Creation of Slides
Learners explore the use of microscopes and the creation of slides. They practice using, adjusting and viewing with a microscope. they view slides of familiar substances such as blood and fibers. In addition, they create slides using...
Curated OER
Microviewer
In this microviewer instructional activity, learners observe several types of cells. Students draw each type of cell and label the important parts. Learners also answer questions relatable to the cell and the purpose for study.
Curated OER
You...Instead of the Onion Skin
Learners observe their own epithelial cells from the inside linings of their cheeks using DigiScope technology. They prepare a slide with both onion cells and epithelial cells and make an illustrated booklet for a PowerPoint presentation...
Curated OER
Seeing Cells
Sixth graders study living cells and their functioning units. In this cell lesson students color cell diagrams, answer questions and discuss the differences between plant and animal cells.

DNA Structure, Function and Replication
Before a cell replicates, its DNA must replicate. Take advantage of a hands-on guided lesson to teach budding scientists how this happens. Using a set of nucleotide cards, learners become the DNA and work to create matching strands...
Curated OER
Underneath the Microscope
Eighth graders enhance their skills in operating a microscope. They become comfortable with the vocabulary associated with microscopes and investigate how to place slides and focus them properly using the microscope. Students are given...
Curated OER
DNA Profile Analysis
Students obtain a DNA sample, observe DNA Using Agarose Gel Electrophoresis, and obtain reagents and equipment.
