December 19th - Tuesday - Board pics and notes - Meiosis handout -


The note home today:
Hi Scientists;
Again, 'meant to send this to the Environmental Science classes as well as the science classes because evolution and Natural Selection are studied in both. In science we're diving into the mechanism of evolution. How traits and genes change over time.
Attached are the science notes and a YouTube video recap for today.

For the Meiosis handout the main take-away is the end result - four (4) haploid cells. We're going to be focusing on Prophase tomorrow.

Happy Tuesday everyone - Scott Forbes - www.pacificascience.org

The note home today ...

Hi Scientists;
This is meant for all classes as we're studying evolution and the diversity of life. In science the next month will be focusing on the mechanism by which evolution has produced such diversity of four billion years! In Environmental Studies we're focusing on the diversity we've lost over the last century and how to protect what remains.
Attached are the board pics from science.

In Science, be sure to check your answers for pages 157 and 163. (One the website www.pacificascience.org, and in your Google Classroom.)
Have a good Monday everyone -

California Biomes Assignment - ES

 California Water and Biomes

Include one slide for each of the following:

  1. Each slide must have a picture of the California Biome
  2. There are six California Biomes (Marine, Forest, Freshwater, Grassland, Desert, and Tundra) 
  3. Include one animal species found in each biome. Make sure to include both the common and scientific name.
  4. Include one plant species found in each biome along with the scientific name.
  5. How much annual rainfall does each biome receive?
  6. Write a few sentences describing the biome. In other words, if you found yourself in that biome; what would expect to see, smell, hear, feel, etc.
  7. Name one environmental challenge facing the biome. In other words - something that may have a negative impact on biodiversity. Example: As global warming takes hold deserts - which are already hot and arid - may become unlivable for some species that currently reside there.

Today's note home:
Today 1:00pm

Hi Scientists;
We're moving from viruses to cells with a focus on genetic diversity and mutation. We caught just ten minutes from the movie "Contagion" (2011) - a movie which did a good job of predicting some of the social and biological realities of the Covid pandemic which would hit only eight years later. Below the YouTube video, and. here, I'll link the brief scene where Dr. Mears, played by Kate Winslet, tried to get ahead of the virus and bring down the R-Value. We saw the CDC and the WHO do exactly that with Covid - 19 ... Here's the scene;
In an overview of Mitosis and Meiosis we watched the Amoeba Sisters in a brief clip ...

Today's notes are attached and are posted at the website... Have a nice Tuesday everyone!

December 6 - Wednesday - Notes and video - Science -


Hi Scientists;
This note is going to Environmental Studies, as well, because we discussed DDT and pesticides today. Today's notes are attached. The previous notes are in the Google Classroom and at www.pacificascience.org.
(Local Science tie in) When DDT was sprayed it, among other things, caused birds to lay very thin eggs. (Thus, "Silent" Spring - no birds - From the famous Rachel Carson book published in 1962.) Near San Bruno / Millbrae (near the reservoir) there have been sightings of a Bald Eagle this month! Over at Devil's Slide Trail there is a nesting pair of Peregrine Falcon currently ... Both bird species that were endangered partly due to wide spread DDT spraying.
YouTube Video recap for today:
Happy Wednesday everyone! - Scott Forbes
