What is an infectious disease? An infectious disease is a disease and/or sickness that can be spread by personal contact. What i mean by personal contact is if for example you have the common cold you can easily give someone the cold just by touching them, coughing, or just by sneezing beside them. Examples of some infectious diseases are the flu, the common cold, a strep throat, etc.
How do you get an infectious disease? A few ways you can catch a sickness is if someone who’s sick sneezes. Sneezing is a way for a person to let out those germs that were in your body, a sneeze can produce droplets that contain those germs and it can stay in the air for at least 10 minutes, so that’s why you need to cover your mouth when you sneeze. It can also spread through skin to skin contact, coughing, and contaminated items.
How can you prevent an infectious disease? Ways to prevent your sickness from spreading is to wash your hands as much as possible. You want all those germs that are of your hands to be gone so that way you don’t get others sick when you touch them. Other ways to prevent illnesses is to not touch your face, get enough sleep, eat healthy, and work out regularly.
What can you get rid of an infectious disease? Illnesses like the cold, a fever, or like the flu can be treated easily as long as you don’t spread it to others. You can treat illnesses like these by letting your body rest and heal by itself, your white blood cells are working hard to get rid of the germs that are causing the sickness. Other ways of getting rid of your illness is to stay hydrated, relieve your pain, and consume warm liquids.
One important way you can help to stop a big infectious disease is to stay home and slow the process of that illness from spreading from person to person. These pieces of information can hopefully help you stay safe during this outbreak of coronavirus (COVID-19) and help the cases go decrease by staying home. And if you are sick from a different illness then please take care of you and the people around you by looking at ways to prevent your sickness from spreading.

During the three-week long shut-down, biology students who wish to earn Honors credit had the opportunity to continue their learning with assignments that are now required learning. Several of you shared Google Docs with me which documented your efforts to work through some of the material. I sincerely applaud your efforts! Keep up the good work!
Now that we are back “in school” via distance learning and have the go-ahead to begin teaching new material, many of the assignments originally labeled as Honors credit work will now be required new learning for everyone.
The criteria for earning Honors this semester has been simplified for this class: Students who earn an A for the semester in Mr. Swart’s Biology class will receive Honors credit. This is not a simple task, especially given the challenge of distance learning. However, I invite you all to give it your best effort and make it your goal to earn Honors credit!
The Balancing Chemical Equations Gizmo ends by classifying chemical reactions into five different categories:
- Combination: A + B → C
- Decomposition: A → B + C
- Example: 2H2O2 → 2H2O + O2
- Single Exchange: AB + C → A + CB
- Example: K + H2O → H2 + KOH
- Double Exchange: AB + CD → AD + CB
- Example: Na2S + 2HCl → 2NaCl + H2S
- Combustion: fuel burning in the presence of O2
- Example: CH4 + 2O2 → CO2 + 2H2O
Our new learning for this week is to further investigate the types of chemical reactions.
- Begin by reading Lesson 73 (Types of Reactions) in our online chemistry textbook. Chemistry textbook login instructions are provided at the bottom of this post.
- Next, review the Notes for the chemical reaction videos you will be watching and analyzing. This is important! Open it! Read it! You are about to watch a series of videos showing chemical reactions. After each video, you will complete the following three multiple choice questions:
- Which piece(s) of evidence did you observe that a chemical reaction has taken place?
- Select the correct balanced equation.
- What type of chemical reaction was this?
- Practice watching and analyzing chemical reactions. In this assignment, you will watch videos showing 5 different chemical reactions. After each video, you will answer the three questions listed above and receive feedback for your answers. The assignment is worth 10 points. To earn full credit, put forth full effort. Click here for the Types of Chemical Reactions Assignment.
- To receive credit, the assignment must be completed by Sunday, April 19 at 11:59pm.
- After completing the assignment, go back to the Week 30 – Types of Reactions page.

Next, let’s “talk” Chemistry! Our focus this week involves revisiting two concepts that were introduced just before the shut-down: Balancing Equations and Types of Reactions.
- Visit the Balancing Equations post to review our work from school and to watch a couple of excellent review videos.
- With all of the craziness that last week of school, quite a few students did not have the opportunity to turn in the Balancing Chemical Equations Gizmo. The Gizmo was sent to your student Gmail if you need a copy.
- How do you turn it in? You have options:
- Print it out, complete the work, then email me back a scanned copy.
- Don’t have a scanner? Email me pictures.
- Don’t have a printer? Write answers on a sheet of paper and email me a picture of your work.
- Even better, save a tree! Type answers in a Google Doc and share the Doc with me. Name the document “Balancing Chemical Equations Gizmo – student name” (example: Balancing Chemical Equations Gizmo – Baxter Swart).
- Need extra help? Attend my science office hours via Zoom on Tuesdays (11am-12pm) and Thursdays (1pm-2pm). You are always welcome to email me as well. You absolutely must advocate for yourself. I am here to help you – please reach out!
- After emailing Mr. Swart your completed Gizmo (or checking Synergy to verify you already turned it in and received credit), go back to the Week 30 – Types of Reactions page and proceed to Step 3.
For the remainder of the school year, we will be learning about evolution. After being out of school for the last month, you might be feeling a little bit lost with this week’s lesson. Time to refresh!
Unit 1 focused on making the connection between molecules and organisms. You learned about cells, biomolecules, and metabolism, Central Dogma, and homeostasis. All of that helped you answer the question: How do organisms live and grow?
Unit 2 focused on Ecosystems: Interactions, Energy, and Dynamics. You took a virtual road trip to Yellowstone National Park. Along the way, you explained how and why organisms interact with their environment, and evaluated the effects of those interactions through the lens of rewilding.
Unit 3 focused on Heredity: Inheritance and Variation of Traits. You learned about cystic fibrosis and how genes, found on chromosomes, code for traits. You then researched a gene on a chromosome and shared your learning with the class. Throughout the unit, you acquired the knowledge necessary to explain how characteristics of one generation are passed to the next, and why individuals of the same species and even siblings have different characteristics.
If any of this feels like a distant memory, you need to review! Browse through the units, focus on areas that seem unfamiliar, and own your learning. As we work through Unit 4, Biological Evolution: Unity and Diversity, we will answer the following Research Question: What evidence shows that different species are related? We will draw from our learning from throughout the year to answer the Research Question – buckle up!
First off, we need to “talk” logistics, or how our science class will operate as we engage in distance learning:
- Tuesdays are new Science learning days.
- New Chemistry lessons will be posted each week on Monday mornings at 8:00 (in case you want to get ahead!)
- Work for the week is due by Sunday at 11:59pm after the Tuesday it was assigned.
- Office hours will take place through Zoom meetings on Tuesdays (11am-12pm) and Thursdays (1pm-2pm).
- You will receive meeting instructions to your student Gmail before each meeting. Attendance is optional but encouraged.
- Check your student Gmail account daily. Email me any time with any questions, comments, or concerns you have.
- To make sure you fully comprehend the information on this page, take the Week 30 – Logistics Quiz!
- After completing the quiz, go back to the Week 30 – Types of Reactions page and proceed to Step 2.
Next, let’s “talk” Biology! Before COVID-19 shut us down, we learned all about our inner animals. With the return of school via distance learning, our study of evolution continues with learning Charles Dawin and the Voyage of the Beagle. Here is the assignment:
- Watch the HHMI Biointeractive video below.
- Next, you will follow in Darwin’s footsteps as he explored the Galapagos Islands.
- If you have access to Internet Explorer, open the Explore the Galapagos feature on the PBS NOVA website where you will take a tour of where Darwin went and what he observed.
- For those without access to Internet Explorer, my apologies. This type of interactive activity requires Adobe Flash which is blocked by the Chrome browser. Do not despair! You are in for a treat! Using the free software OBS (Open Broadcaster Software) to capture my screen, I’ve created three video walk-throughs of the Explore the Galapagos tour. Answers to the questions below are found within the video linked to the question. You will need to pause the videos frequently in order to read the content.
- Create a Google Doc titled “Name – Week 30” (example: Baxter Swart – Week 30).
- Share the doc with firstname.lastname@example.org
- Copy the questions below into your doc and then answer them all in complete sentences using the Explore the Galapagos website or the video walk-throughs below:
- Where are the Galapagos Islands?
- First click on “Explore the Islands” and read about three of the islands. Summarize one observation for each of the three islands you read about.
- Now click on “What Darwin Saw”. You will be going through his various stages, reading about what Darwin said, and listening to interviews. Summarize Darwin’s first impressions (just writing the opening sentence will get you zero credit, click for the full story).
- What surprised Darwin on the islands?
- What did the tortoises offer the local people? How did it benefit Darwin?
- At first Darwin thought the birds were unrelated, but what ideas eventually came from his observations of the finches?
- What was the fallout (or result) of Darwin’s journey?
- Go back to the “Explore the Islands”. Look at some of the interpretative panoramics and the animals. Pick two animals and summarize their unique characteristics.
- Look at “Darwin’s Finches”. What do you think it means by unique niche, based on what the rest of the paragraph says?
- How are the beaks different and why was that important?
