Toxins: Physical versus Chemical Change

Because I am out of the school building tomorrow and prefer not to have our substitute conducting a lab, I’ve decided to have students work through Lesson 70 and we will revisit Lesson 69 soon.  For Lesson 70, students are welcome to review the Lesson 70 PowerPoint and then should work in small groups to complete the Lesson 70 Worksheet.

For additional background, watch the video below from Mr. Anderson of Bozeman Science:

Toxins: Chemical Equations

To begin class, students received an extra 20 minutes to complete their Unit 3 Exams from last week.  After that time (or before for students who were ready), students received the Lesson 68 Worksheet and Toxin Card Deck, along with a graphic organizer for analyzing the card deck.  After the time for the exam concluded, we worked through the first few slides of the Lesson 68 PowerPoint, and students watched a video showing the chemical reaction written on the worksheet.

Variation and Inheritance: Sources of Inherited Genetic Variation

March 30: Today is the final day of the project – tomorrow you present your work to the class!  To earn full credit for the presentation, you need to practice your presentation multiple times.  Practice pronouncing all of the words, and look up the definitions of the words you are using to clearly indicate you understand what you are saying.  The website has a pronunciation feature – you can look up the definition of the word in question and also click the speaker to hear it pronounced.  It also has a translate feature.  If you are presenting with a partner, you need to decide in advance of your presentation who will say what.  You both need to know the content and how to pronounce all of the words.

March 29: Remember to read the project outline carefully!  For your presentation, you will make either a PowerPoint (Google Slides) or a poster.  Poster paper is available in the cardboard box against the wall under the whiteboard with the daily bell schedule.  For Google Slides presentations, you are welcome to include short videos (must be school appropriate!!!) depicting the reproductive strategies of one or both of the organisms you selected.  Remember, presentation time is limited, so the videos must be brief, or you must identify a segment of the video to show in advance.

Need more challenge?  Add an organism – but select one from a different biological kingdom than the organisms you have already researched.  Remember, you must have two organisms in your presentation to earn full credit.  However, for each additional organism you include, you will earn 5 points of extra credit!  The six different kingdoms are pictured below:
