The Biology Place

(www.phschool.com/science/biology_place/)

Age Range: 10-18 (Grades 5-12, with parental supervision)

 

This site, sponsored by textbook publisher Pearson, offers free biology lessons and lab animations. This multi-media resource can be used in conjunction with any basic biology textbook or curriculum, or as a fascinating exploration for the incurably curious.

When you get to the website you’ll see a menu of three items: 

  • BioCoach – This section is designed for reviewing and enhancing biology information gleaned from textbooks and classroom lessons. However, the animations and interactive aspects really help all learners (including those outside classroom walls) to visualize and understand biological concepts including: 
    • Biomembranes
    • Biomolecules
    • Cardiovascular System
    • Cell Structure and Function
    • DNA Structure and Replication
    • Meiosis
    • Mitosis
    • Plant Structure and Growth
    • And more!
  • LabBench – This is an interactive virtual lab that helps students further understand basic biology concepts. References are made to actual classroom lab activities (for example, an instruction to look at a slide under a microscope). However, the virtual lab offers a picture of what you would see if you were viewing the slide through a microscope. So, while you might not have the hands-on experience, you can still learn a lot. You can even take a quiz at the end of each lab to see what you retain. There are 12 labs in all that include: 
    • Diffusion & Osmosis
    • Enzyme Catalysis
    • Mitosis & Meiosis
    • Plant Pigments & Photosynthesis
    • Cell Respiration
    • Molecular Biology
    • Genetics of Organisms
    • Population Genetics
    • Transpiration
    • Circulatory Physiology
    • Animal Behavior
    • Dissolved Oxygen
  • Glossary – Get definitions of biological words, terms, and phrases.

This is a good resource for introducing biology concepts, supplementing any study of biology, and it can be used to refresh your memory about biology course material as well.

Serendip – Biology

(serendipstudio.org/sci_edu/waldron/)

Age Range: 11-18 (Grades 6-12, with parental supervision)

 

This website that offers FREE hands-on activities for teaching biology to middle school and high school students.

These activities were designed by a graduate student of the Biology Department at the University of Pennsylvania who notes, “The expression ‘hands-on, minds-on’ summarizes the philosophy we have incorporated in these activities — namely, that students will learn best if they are actively engaged and if their activities are closely linked to understanding important biological concepts.”

When you get to the site you’ll see an introduction followed by the lessons with Student Handouts and Teacher Preparation Notes available in either PDF or Word formats. (You can also access the activities by clicking on the “Table of Contents” menu on the right side of the screen.) The activities cover a broad range of biological topics and are presented in one *possible* effective sequence for learning biology. Here is a sample of activity titles: 

  • Is Yeast Alive?
  • Introduction to Osmosis
  • Photosynthesis Investigation
  • Mitosis, Meiosis and Fertilization
  • Dragon Genetics
  • DNA
  • Moldy Jell-O
  • Regulation of Human Heart Rate
  • How do we Sense the Flavors of Food?
  • And so much more!

As noted at the website, most of the activities can be carried out with minimum equipment and expense for supplies. Sources for the equipment and supplies you’ll need are provided in the printable “Teacher Preparation Notes.”

Biology – A Tour of the Cell

(www.nsf.gov/news/overviews/biology/interactive.jsp)

Age Range: 11-18 (Grades 6-12, with parental supervision)

 

Can you imagine how many millions of these tiny cells are inside of your body at this very moment? Amazing! This tour of a cell from the National Science Foundation is very detailed and informative.

“Although the cell is the smallest unit of life, it is by no means simple.”

Thus begins this brief-but-fascinating exploration. The opening picture is a large, full-color image of a cell. To begin, click on any of the numbered parts of the cell and a beautiful, detailed close-up image of that cell art will appear, along with one or two paragraphs of information about it. Parts featured include: 

  • the cell membrane
  • DNA
  • RNA
  • endoplasmic reticulum
  • mitochondria

and more.

Once you have viewed a part of the cell, you will see small numbers below the photo of that part. These numbers provide a convenient way to navigate through the site sequentially, if you prefer. If you click “Explore More,” you will go back to the main page.
