If you are unable to send your work to me electronically or email it to me then you need to deliver your work to the school and have someone in the office place it in my teacher mailbox.
The following people need to email me a picture of their completed animal and plant cell coloring sheets: Keion, Mark, Rebecca Jo, Ne'Vaeh, Alberto, Alexis, and Mya.
The following people need to email me their completed Grape Activity: Keion, Dylan, Jaylin, Mark, Rebecca Jo, Jasmine, Ne'Vaeh, Ethan, Kadarous, Alberto, Alexis, Mya, Harley, and Etrinity. Grape Activity Instructions are below.
The following people need to log on to Gradecam and complete the online Trial Run Test: Keion, Blazlea, Ne'Vaeh, and Mya.
The following people need to watch the Sodium Potassium Pump Video,
take the 5 question quiz that follows the video, and then log on to Gradecam and submit the answers online: Keion, Rebecca Jo, Ne'Vaeh, Alberto, Mya, and Harley. Sodium Potassium Pump Video
Everyone needs to complete the major online test this week on the following information: Microscopes, Cell Theory, Cell Types, Cell Structures, Cell Functions, and Cell Transport. This test has been posted on my webpage, sent it to all of you attached to an email, and I sent it to you in via text. The school can provide you with a hard copy of this test if you need it. The test needs to be finished and submitted through Gradecam by Friday before Spring Break begins.
I am hosting 4 Kahoot Challenges that you are welcome to complete to help you prepare for this test.
- Microscopes: Code to join is 0399218 (ends Wednesday)
- Cell Theory: Code to join is 090952 (ends Wednesday)
- Cell Structures and Functions: Code to join is 0181113 (ends Thursday)
- Cell Membrane and Cell Transport: Code to join is 0712373 (ends Thursday)
If anyone is interested in having a Zoom Review Sessions please let me know by email or text.
LRL Biology Unit Test 1 for Spring Semester.
A hard copy of this test is available at the school. This test is also on my webpage as an assignment, I sent it to you in an email, and I will send it to you via text.
This test is optional. Remember, if you do better on this Unit Test it replaces your lowest test grade for the 9 weeks. Taking this test cannot hurt your current average, it can only improve your average. You may use your notes on this test. This test must be submitted to me electronically through Gradecam by Tuesday.
If you can't send it electronically then deliver it to the school and have them put it in my teacher mailbox. It is best to send it electronically because this ensures social distancing.
I don't need the bubble sheet unless you are bringing the test to the school.
You should include the following in your Grape Activity Write Up:
Question: What will happen to the mass of three grapes if one is placed in water, one in sugar water, and one in grape juice for 96 hours?
Hypothesis: If one grape is placed in water, one in sugar water and one in grape juice for 96 hours then the mass of the grape in water will ___________, the mass of the grape in sugar water will _______________ and the mass of the grape in grape juice will _______________.
(I was uncertain of the data for some of the groups so I would like everyone to use my data)
Create a Data Table for the following information:
Initial Mass of Grapes: Grape in Water - 13.92g, Grape in Sugar Water - 15.89g, Grape in Grape Juice - 16.26g
Final Mass of Grapes: Grape in Water - 16.05g, Grape in Sugar Water - 12.86g, Grape in Grape Juice - 16.26g
Analyze Data and Answer the Following Questions:
What kind of solution was each grape in (hypertonic, isotonic, or hypotonic)?
Did each grape's mass increase, decrease, or stay the same?
If the mass increased or decreased then by how much?
Explain why the mass of each grape increased, decreased or stayed the same, by describing what happened with the movement of water into and out of the grape's cells.
One observation you might want to include is the final appearance of the grapes. The grape in water was so swollen it burst in a few places, the grape in sugar water looked shriveled, and the grape in grape juice basically looked the same.
Conclusion: When one grape was placed in water, one in sugar water and one in grape juice for 96 hours the mass of the grape in water ___________, the mass of the grape in sugar water _______________ and the mass of the grape in grape juice _______________. Therefore, the hypothesis was _______________.
