3-14-18: Students were asked to complete and submit for grade the graphical presentation of literacy vs. fertility from yesterday (p. 232) along with responses to the questions on that page. We looked at two ways this data can be clearly presented to observe the inverse trend: One way was a double bar graph with one variable plotted in an increasing or decreasing trend. The other way is by plotting each variable on an axis and plot a point for each country. In both cases, an inverse trend is explored. An excellent exploration of this data can be found at (reference link #142). Once this activity is complete, students should begin the chapter review problems on page 235 in preparation for the exam.

As credit toward grade, and handed in as an exit ticket (if possible), students were required to summarize the testing procedure and findings of the two experiments in "Dogs Decoded" and write a personal reflection.

10-25-17: We continued "Your Inner Fish" to 47:46. We spoke about organizations of life and began a discussion of life classification (e.g. vertebrates and invertebrates, types of vertebrates, new world life forms, omnivores vs. carnivores....). We watched the section on the Russian Fox Experiment from "Dogs Decoded" (see reference link #133. On-line links to the Inner Fish series can be found in reference link #133.

10-16-17: We continued "Birth of the Earth" to 29:38 and had discussions that included some of other links and videos like the collision of comet Shoemaker-Levy with Jupiter and some from reference links #115 ("How Uranus got its name" and "Why Pluto is no Longer Considered a Planet"). Students performed several "Stop and Jot" sessions, describing discussion topics and we paused the video and handed in papers for credit toward grade.

We discussed the Goldilocks fairy tale and I showed a video from the "Secrets of the Earth" series. Students submitted 10 facts from the video as credit toward grade. Since this video is not available on-line (Send me the link for extra credit if you find it!), I offer the following alternative assignment for students who missed the video: Respond to the following prompts after performing on-line research:1 - Using the analogy of the fairy tale, describe the Goldilocks zone as it relates to the position of the earth. 2 - Describe the natural geologic processes by which CO2 is produced and absorbed in rocks and minerals (tectonic plate theory should be incorporated in your response). 3 - Explain how our moon and the planet Jupiter help make the earth a habitable planet.

10-6-17: We discussed the proposed Aquaponics projects and students wrote a personal reflection on this project and whether they would want to be involved in an afterschool club as credit toward a grade. This writing was handed in as an exit ticket (See reference link #127 to watch a short video). We completed the video Home and students submitted the video WS for credit toward grade.

We discussed how the variables would be presented on an x-y graph. Students paired up and conceived an experiment that tested a variable then submitted a description of thier experiment as credit toward grade. We discussed several. Then we completed "Strange Days...Part 1" and students submitted the video worksheet as credit toward grade. Those who want to explore the "How Wolves Change Rivers" trophic cascade concept discussed yesterday should watch "Strange Days on Planet Earth - Part 3" from 20:30 to 31:25.

9-11-17: Students were asked to write a response to the prompt: How might humans respond to an invasive species that destroyed corn crops?". Students are to include that response on the video worksheet from Friday. We discussed this prompt and examined the threat of "Loss of biodiversity", discussed on page 15 of the textbook. We discussed human populations growth and its impact on our planet. I checked the HW (6 key term definitions for chapter 1) for a grade. WE continued the video to 15:30.

9-8-17: Students were shown how to access the online textbook. Key terms definitions for chapter 1 are due Monday. We discussed the concept of an invasive species.

Key Terms are due as a homework grade. I demonstrated the Methane Mamba and students were asked to consider the equipment and procedure to perform this demonstration safely.

9-5-17: First day of class. I hope you felt welcome and enthused about the subject. Students received a hard copy print of the syllabus to keep in their notebook and were assigned seats. Note: The syllabus is available in digital format as item #1 on the tab titled "Assignments /EC" on the left. Your homework tonight is to complete the two-part prompt handed out in class.
