Michelle's Biology Collection - June 25th

The first biology collection is due June 25th. I wanted to provide an example to help alleviate any questions you might have about format, content, etc.

All of your photos for the first collection should be posted in ONE blog entry. This means you will create a post titled "Your name - Biology Collection" and add all the photo's and descriptions to the same entry. Once you've added a few, you can come back later and modify/add more if needed.

Number your photos or captions. This will make it easier to keep track of your progress. I will be looking for photos of biology concepts and brief explanations of what the concept means. Does your photo illustrate the idea? The explanations should not be long, but you should use enough detail to satisfy the term chosen. Here is my example:

1. nymph stage of an insect

All insect progress through stages of development. This body development is referred to as complete or incomplete metamorphosis. The beginning stage of complete metamorphosis involves eggs hatching into a larvae stage. Larvae stage could include a maggot, grub or caterpillar. Pictured here is a praying mantis nymph, a predatory insect. Mantid's do not have larvae, they undergo incomplete metamorphosis. Insects who develop in this manner are born from an egg sac called a ootheca. The newly hatched offspring resemble the parents but are much smaller in size, lack wings and a functioning reproductive system. The praying mantis nymph must grow and molt. Molting requires that the exterior chitinous shell be replaced as the nymph expands its size and metamorphose into an adult. The nymph may require 5 to 10 molts before it develops into a sexual reproducing adult. Pictured below for comparison is a grasshopper nymph.

  1. How do you post something on here? And do we have to write that much description per picture?

  2. I didn't know how to do this so i played with it... and i think i ended up making a blog which can be found by clicking my name? Sorry for the spacing issues on it, i couldn't fix it.

  3. Daniel, you will need to post to your own blog. Your description should be adequate, don't skimp. The description should clearly describe the term and illustration. If you're not sure, ask a family member to critique it.
