Biology Cell Study

Introduction

Daniel Carlson

Biology Lab

In a laboratory it is important to use the scientific methods. After a hypothesis has

been created, it is time to test the prediction. If the results of the experiments are

plausible, the hypothesis is then adapted to connect with the experiment.

The objectives of this lab are to focus on cell replication.. In Section I, the “Health

and Safety Review” section will give you guidelines to avoid any accidents in the lab

and specify what a student can do to if an accident does occur. In Section II,

“Measurements”, students will become comfortable with the metric measurements., In

Section II, there are other activities about length that will require you to measure a piece

of rope. You will also learn about the different parts of a scientific research report when

viewing Section III. In Section IV “Compound Light Microscopy”, you will use a

microscope. In Section IV you will come across different sub-sections, such as the first

activity which is “Safe handling of the microscope” where you will use a light microscope

and explore its different features. This eventually leads to the activity where you will

make observations with the compound light microscope, in activity 4 you will determine

the actual size of specimens using a microscope.

Materials for Section I: Health and Safety

-

Safety: Observation & Measurements packet, shower and eyewash

station, fire extinguishers, first aid kit, closed toed shoes, lab coat, and safety goggles.

Materials for Section II: Metric Measurements

-

Activity 1 (Length): Lab coat, safety goggles, ruler, and a piece of rope.

-

Activity 2 (Weight is a measure of the mass of an object under

gravitational pull): Lab coat, different objects to weigh, safety goggles, and a loading

scale.

-

Activity 3 (Volume is a measure of the material): Graduated cylinder, lab

coat, safety goggles, 100ml of water, and loading scale.

Materials for Section III: The...
