B’ru haba b’shem Adonai … Welcome Lord Jesus!

Welcome students in the name of Jesus

Let’s look at the texts …

• Biology: God’s Living Creation

• Field and Laboratory Manual– Note: ok to look ahead at Lab Procedures– No written assignments in preparation for

labs… but lab report sheets document completion of the lab.

– Handle only lab equipment as needed for each lab when it is needed. Promptly replace items.

A special word about …

Labs and the RKSI Project

“Road Kill” Scene Investigation Project “Common Sense”

Guidelines• Don’t bring more than we will have time to dissect or

space to store. Assume max of 2 weeks in refrigerator. Check lab schedule for appropriate dates. We’re already close to our storage limit.

• Never collect without adult supervisionadult supervision.• Never physically touch a specimen without wearing

protective glovesgloves or using a collection bag. • Take care to protect eyesprotect eyes from biohazards• Practice cleanliness at all times … WashWash your hands

after every handling (even when wearing gloves)! And washwash the specimen. Remember: Francis Bacon, the father of modern science, died from handling specimens.

Lab Safety

• Never dissect a hand-held specimen.• Never use a scapel or cutting device with more

than one cutting edge.• Never perform unauthorized experiments.• Follow directions outlined in Lab Manual

verbatim and any special instructor directions.• Keep test tubes pointed away from yourself and

others.• Never taste any chemicals or samples.• Follow Dissection lab rules.

Lab Rules

1. Touch nothing in the supply box except what is required for that lab.

2. Tell the teacher if you break something.3. Communications should be in a whisper and should be

only about the lab.4. No laughing or talking between tables.5. Stay in your seats at all times.6. No playing or doing anything not related to the lab.7. Raise your hand without calling the teacher’s name.8. Take your lab manual with you to your lab table and

answer the questions as you work.

Lab Rules specific to Dissections

• Concerns: – The specimens you will dissect in this class will contain no blood

and feel like plastic.– The holding fluid is not poisonous and has a mild odor, if any at

all.

• 1. Know the organs you see and remove no organs.• 2. Be careful and neat.• 3. Do not cut deeply.• 4. Go slowly.• 5. Use scalpel sparingly.• 6. Wash your hands when finished.

Chapter 1

The Flowering Seed Plants

1.1 Intro to Biology

• Biology – the study of living things– BIOS – ‘life’– LOGY – ‘science of’

• Organisms – living things• Habitats – regions where particular organisms

normally live• Our Study Methodology: reading, use of tools of

science, field observations, collection/research methodologies, dissection of organisms, and scientific analysis and reporting.

Major Fields of Biology• BOTANY – the study of plants• ZOOLOGY – the study of animals• HUMAN ANATOMY AND PHYSIOLOGY- the physical structure and

function of the human body

NOT COVERED WELL IN THIS COURSE:• MICROBIOLOGY• GENETICS [GENOMETRICS, ETC.]• BIOMETRICS• ECOLOGY• DISEASE/DEATH – MORPHOLOGY• BIOCHEMISTRY• ETC.

Our Role in Biology

• Romans 1:20 – For the invisible things of Him from the creation of the world are clearly seen, being understood by the things that are made, even His eternal power and Godhead; so that they are without excuse.

• Genesis 1:28 – And God blessed them, and God said unto them, “Be fruitful and multiply, and replenish the earth, and subdue it; and have dominion over the fish of the sea , and over the fowl of the air, and over every living thing that moveth upon the earth.”

• “The whole earth growns awaiting the awakening of man!”

1.2 Botany

• Importance: 2/3 or food (directly); all really• Classification/Identification Parts of a Plant:

– Flowers (Reproduction)– Leaves (Photosynthesis)– Stems (Classification due to fire)

• Woody• Herbaceous• Vine (neither woody nor herbaceous)

– Roots (Transport/storage)• Taproot• Fibrous• Vegetative reproduction (can look like either eg. Sand strawberry)

– Name a few other parts of plants left out of this list.

Other Plant Parts

• Fruits

• Seeds

Leaves• Parts of a leaf:

– Blade– Stalk (or petiole)– Midrib (on many leaves)

• Three basic leaf shapes:1. Broad, flat leaves

• Leaf margins– Entire – smooth/unbroken– Toothed– Lobed

2. Long, narrow leaves3. Needle-like or scalelike leaves

• Compound leaves− Divisions

− Leaflets
