Foundations of LifeMonday 9/8 - Wednesday 9/25

Monday 9/8Learning Targets:1) I can list some characteristics of life2) I can explain what the goal of science is.

Warm Up:1) How can you tell something is alive? What are the characteristics of life?

Agenda:1) Is it Alive?2) SQ3R Homework Introduction

Homework: Biology Section 1-1 (Should be able to finish in class)

Bacillus cereushttps://www.youtube.com/watch?v=y3TOZ_abECM

Wednesday 9/10Learning Targets:1) I can explain what a hypothesis is.2) I can create and analyze a question that can be answered through a scientific experiment.

Warm Up:1) What areas of the school or house do you think contain the most bacteria? Why?

Agenda:1) The Ubiquity of Bacteria Lab Procedures2) The Horrendous History of Handwashing

Homework: Handwashing Miniposter (Due 9/15)

Ubiquity of Bacteria LabBacteria are everywhere (they are “ubiquitous”). When provided with the right environment, they divide rapidly. Sometimes there are so many, they are visible as a colony. Every colony is composed of bacteria that are genetically identical, having divided from a single original bacterium. In this lab, you will grow bacteria found in three different locations at the school. To prepare for this lab, you will create a lab report. The lab report should include the following:Heading and TitleQuestion: Do equal amounts of bacteria grow everywhere?Hypothesis:Procedure: Include the following:- Logical steps to the experiment - Manipulated (independent) variable - Controlled variables

- Responding (dependent) variable - How often measurements should be taken and recorded - Control and experimental groups

Friday 9/12Learning Targets:1) I can plan and conduct a scientific investigation.

Warm Up:1) Consider what you know about the characteristics of life. What are we providing for this bacteria that allows them to grow/reproduce?

Agenda:1) The Ubiquity of Bacteria Lab Collection

Homework: Handwashing Miniposter (Due 9/15)

Exit TicketHow do you write a good conclusion for a lab report, i.e. what goes into a conclusion?

Monday 9/15Learning Targets:1) I can collect, analyze, and display data.2) I can draw conclusions based on experimental evidence.

Warm Up:For questions 1 and 2, pick the correct answer:1) a. The hypothesis was proved 2) a. The hypothesis was disproved.

b. The hypothesis was supported b. The hypothesis was not supported.

c. Both a and b are correct c. Both a and b are correct

Agenda:1) Portfolio Introduction2)Ubiquity of Bacteria Data and Conclusion

Homework: SQ3R 1-2 (Due 9/17)

Wednesday 9/17Learning Targets:1) I can identify the three types of chemical bonds2) I can explain why water is necessary for life

Warm Up:1) Identify the manipulated variable, responding variable, and two controlled variables in spallanzani’s Experiment

Agenda:1) Using Chemistry in Biology

Homework: SQ3R 2-2 (Due 9/22) ← Make note of change in Unit Calendar

Exit QuestionList the ways that water helps to maintain life. Turn in Warm-Up sheets for grading when done.

Friday 9/19 Learning Targets:1) I can understand and use the pH scale.

Warm Up:1) What is the difference between ionic and covalent bonds?

Agenda:1) Finish Using Chemistry in Biology

Homework: SQ3R 2-2 (Due 9/22)

Exit QuestionGiven the chemical formula of pure water, H2O, why does it have a pH of 7 (Neutral).

Monday 9/22Learning Targets:1) I can understand and use the pH scale.2) I can collect, analyze, and display data.

Warm Up:1) Which would have more H+ (hydrogen ions): something with a pH of 4 or something with a pH of 10?

Agenda:1) Household pH Lab2) Study Guide for Unit 1 Test

Homework: Study!

Wednesday 9/24Agenda● Return Papers● Review study guide● Unit 1 Test● Ecology Pretest

Procedure ExampleProcedure Example:1. Obtain materials (petri dish and agar, 4 swabs)2. Label the petri dish into 4 sections3. Choose 3 areas where you will use swabs.4. Label the petri dish with the 3 swabbed areas in 3 of the sections5. Swab the bacteria into one of the quadrants in a squiggly line.6. Repeat step 5 with the rest of the swabbed bacteria.7. Leave one quadrant the control with just the regular swab.8. Place petri dish into incubator.9. Leave in incubator for 72 hours.10. After 72 hours, check the petri dish.11. If any bacteria grow, record the data by counting the colonies and drawing the petri dish and the bacteria.

Conclusion ExampleMy hypothesis was is there is more use then there will be more growth of bacteria. My hypothesis was supported. The controlled group didn’t have any bacteria and the faucet handles had 52 colonies. When the use of a location is increased the amount of bacteria increases if not cleaned frequently. The faucet handles get used every day and they do not get cleaned often. The fountain handle does not get used as often due to people bringing their own water. So this shows the more use, the more bacteria.

Unit 1 TestWhen you are finished:● Please return papers to the front of

the room● Please stay in your seat quietly until

everyone is done. They were quiet for you, so please be quiet for them as well.

● You may quietly listen to music, but keep your electronic devices out of sight

Exit QuestionsWith a partner, discuss the following graph:1. What does this chart

measure?2. What is the x-axis? y-axis?3. What is the general trend

(what is happening)?4. About what year does the

population start to increase rapidly?

5. Do you think this trend can continue?

6. What are your feelings about this graph?
