Human Evolution Multimedia

Students watched a video clip: Did Humans Evolve? The video clip can be found at this web page:
http://www.pbs.org/wgbh/evolution/educators/teachstuds/svideos.html
However, the PBS video has become somewhat outdated. So now, we watch this video about human evolution:

Students also watched this video clip: Becoming a Fossil. The video can be found at this web page:
http://www.pbs.org/wgbh/evolution/library/04/3/l_043_01.html

Human evolution was demonstrated by observing this online activity:

Bag-like sea creature was humans' oldest known ancestor: A tiny sea creature identified from fossils found in China may be the earliest known step on an evolutionary path that eventually led to the emergence of humans: Researchers have identified traces of what they believe is the earliest known prehistoric ancestor of humans -- a microscopic, bag-like sea creature, which lived about 540 million years ago.

Video Clips that I show in Biology 1

My Blog is here: http://www.cavalierscience.blogspot.com

Need a textbook to help you study? A free online textbook can be found here:

http://www.ck12.org/biology/

CK-12 Biology is a high school FlexBook covering cell biology, genetics, evolution, ecology, microorganisms, fungi, plants, invertebrates, vertebrates, and physiology.

This book is available for download on your iPad with iBooks or on your computer with iTunes - FOR FREE! I was also able to find the textbooks on my Kindle and download them for free.
There is a student version http://www.ck12.org/student/ and teacher version http://www.ck12.org/teacher/ of the website. CK-12.org just announced that they have integrated their content with Schoology https://www.ck12info.org/blog/ck-12schoology-easier-lesson-planning-save-time/

If you would like to be a Citizen Scientist and participate in our bird watching project, you can register at http://ebird.org/content/ebird/ and submit your observations. We have a birding hotspot here at Middletown High and you can watch birds at the pond and submit your observations to the Middletown High School Pond birding hotspot: http://ebird.org/ebird/hotspot/L2346801 Check it out!

The Germ Theory. The video clip is on this YouTube link:

https://www.youtube.com/watch?v=BxA-a4_SPME

Students wrote down the following questions in the Journal Section of their binders:

1. How does the scientific meaning of a term like theory differ from the way it is used in everyday life?

2. Can the "facts" of science change over time?

3. Who was Charles Darwin?

4. How did public opinion of his day affect Charles Darwin's willingness to publish the Origin of Species?

After watching the video, students answered the questions in their lab notebook.

Students may watch and review the video clips Isn't Evolution Just A Theory? and Who Was Charles Darwin? at this web site:

Note 1
For those who are interested in the Tiktaalik, there is an activity in this textbook: SEPUP. (2011). Science and Global Issues: Biology. Lawrence Hall of Science, University of California at Berkeley. Published by Lab-Aids, Inc., Ronkonkoma NY. The activity is Evidence from the Fossil Record - Activity 6 pp. 446-453. Students explore transitional fossils in an portion of the activity titled Studying Fossils to Determine the Origin of Tetrapods. The Tiklaalik is one of the transitional fossils presented in the activity. The videos listed above enhance interest in this activity.
There is also a 2011 episode of Mysteries at the Museum travel channel show where near the end of the episode, information is presented about the importance of the Tiktaalik fossil and it is explained that the fossil is housed at the Academy of Natural Sciences in Philadelphia, PA. http://www.travelchannel.com/shows/mysteries-at-the-museum/travel-guides/outlaw-shoes-and-astrochimp-travel-guide It looks like the video would be on Disc 2 of Season 2 of the show that can be purchased from Amazon.com. The episode is titled Outlaw Shoes, Astrochimp, and Message in a Bottle. I have not purchased the video and am not 100% certain that it is on the CD. If anyone reading this blog knows how to obtain the Mysteries at the Museum, Tiktaalik video or a video clip, please leave a comment.

Cracking the coldest case: How Lucy, the most famous human ancestor, died

Cracking the coldest case: How Lucy, the most famous human ancestor, died: Lucy, the most famous fossil of a human ancestor, probably died after falling from a tree, according to a new study. Researchers have found that the injury Lucy sustained was consistent with a four-part proximal humerus fracture, caused by a fall from considerable height when the conscious victim stretched out an arm in an attempt to break the fall.
