The metric system
The metric system is a decimal-based system used widely for measurement. It features prefixes that are multiples of 10, ranging from kilo (1000) to milli (0.001). Common metric units include meters for length, grams for mass, and liters for liquid volume. To convert between units, you multiply or divide by powers of 10 - moving the decimal point right to multiply and left to divide. For example, 1000mm = 100cm or 100cm / 10 = 10dm. The metric system is used internationally, especially in science and engineering.
Units of measurement
This document discusses units of measurement and significant figures. It introduces the International System of Units (SI) which uses standard units like meters, kilograms, and seconds that are based on precise properties. Prefixes indicate powers of ten. Mass is a measure of matter, while weight varies by location. Volume is space occupied and is often measured in liters or milliliters. Conversion between units uses dimensional analysis. Measurements have uncertainty related to accuracy and precision. Significant figures determine the precision of calculations based on counting digits and rounding appropriately during arithmetic operations.
Measuring
This document provides instructions for measuring volume, temperature, and mass using common laboratory equipment. It describes how to properly read the meniscus of a graduated cylinder at eye level to determine volume within one uncertain digit. For temperature measurements, a thermometer should be read at eye level with the bulb not touching any surfaces. Mass is determined on a balance by positioning riders along the beams until the pointer is at zero, with the last digit placed being uncertain. Correct technique helps avoid parallax errors and provides accurate scientific measurements.
Measurements
This document discusses the history and types of measurement systems. It describes how ancient Egyptians used body parts like hands, feet and elbows to measure things. It then explains the modern metric and US customary systems of units. The metric system uses prefixes like kilo and milli that are powers of 10, while the US customary system includes units like inches, feet and gallons. The document emphasizes that the metric system is now the worldwide standard and easiest to use due to its base-10 numerical structure.

Metric System
The metric system was devised in 1791 by the French Academy of Sciences to create a standardized system of measurement. It uses a base-10 system and standardized units like meters, liters, and grams that are related by powers of 10. Conversions between units are easy by moving the decimal point a place for each power of 10. The metric system was widely adopted and later renamed the International System of Units. It provides standardized units and prefixes to measure length, volume, mass, and temperature.
Converting units of time

Mass and volume
Mass is the amount of matter in an object and does not change with gravity, while volume is the amount of space an object occupies. There are two ways to measure mass - using a balance scale or electric scale. Volume can be calculated by measuring an object's dimensions or using water displacement to find the volume of irregularly shaped objects. Mass and volume are both measures of the amount of three-dimensional space an object takes up but are not the same.
Si Units
Physics is the study of the natural world and how physical objects behave. It began in ancient Greece when early scientists called "physikoi" tried to understand the natural world using observations and experiments. Today, physics involves measuring various quantities accurately using standardized metric units like meters, kilograms, and seconds. Measurements in physics consist of a number and a unit, and the International System of Units (SI) precisely defines the fundamental base units and derived units used in physics.

This case study examines George, a prosperous lawyer who is diagnosed with ALS in his mid-50s. The diagnosis leaves George feeling disappointed and thinking about how the disease will affect his lifestyle, as he sees himself becoming a burden in a wheelchair, unable to talk or live independently. The student discusses how suffering has become part of human existence, but in the Christian view, God and Jesus Christ offer healing and restoration. The student argues that while God did not intend for suffering in his creation, it entered the world as a result of sin by Adam and Eve. Christians see suffering as ultimately permitted by God to draw people closer to him and help them appreciate health and life.

Exercise 1
THE CALORIE
INTRODUCTION
All animals, including humans, need to consume energy in order to survive. We
call this energy food. The unit which is used to describe the energy content of food is
the Calorie (food calorie, note the capital ‘C’). One calorie (note the lower case ‘c’) is the
energy required to raise one gram of water by one degree Celsius. The food Calorie is
defined as 1000 calories or one kilocalorie (kcal). Most scientists not dealing with food
now use other units such as joules or British Thermal Units (BTUs) to measure energy,
but the Calorie is still used to describe food energy.
The Calories in food are measured using a CALORIMETER, which is a special
combustion device designed to burn food samples completely and capture the energy in
a water jacket. For a 100% efficient calorimeter, the energy captured is equal to the
energy content of the food as shown below:
Energy captured = (mass of water) ´ c ´ (Temp. change) = Energy Content (1)
The constant c is the specific heat of water and is equal to 1
Cg
cal
°
(one calorie per
gram per degree C). In our case, however, the calorimeter we use will capture only a
fraction of the total energy, so we must account for this reduced efficiency.
THE CALORIMETER
The device that scientists use to capture the heat energy of a combustible mixture
is a bomb calorimeter. It is a metal chamber which is supplied with a measured amount
of oxygen during the combustion of the test material. The heat from the burning
material is transferred to a water reservoir that surrounds the metal chamber containing
the test material. The change in temperature is used to determine the number of calories
that the material originally held. A bomb calorimeter is very nearly 100% efficient. It is
also very dangerous (thus the name ‘bomb’ calorimeter) and so we will use a simpler
(but less efficient) type of calorimeter.
A SIMPLE CALORIMETER
The simple but effective calorimeter we will use consists of a calorimeter can (a
metal cylinder with a notch out of the bottom), a calorimeter lid to hold a 125 ml flask, a
flask stopper and thermometer, a sample holder and some tools. Each group of students
will have their own calorimeter to use. Because these simple calorimeters are not 100%
efficient, the water will not capture all of the energy content of the food. Therefore, the
equation for this calorimeter must be modified to:
Energy captured = (mass of water) ´ c ´ (Temp. change) = Energy Content ´ e (2)
where e is the efficiency of energy capture by the water. With this equation and a food
item of known caloric content, we can determine the efficiency of our calorimeter and
2
explore why the efficiency might vary from one group to another. Once a consistent
efficiency is achieved, we can use that efficiency to determine the caloric content of any
combustible item.
OBJECTIVES:
1) To measure the energy content of a food sample. ...

Introduction
Just like you and your friend communicate using the same language, scientists all over the world need to use the same language when reporting the measurements they make. This language is called the metric system. In this lesson we will cover the metric units for length, mass, density, volume and temperature, and also discuss how to convert among them.
Metric Measurement
What do all of these words have in common: thermometer, barometer, diameter, odometer and parameter? All of these words end in
-meter
. You have probably heard this word before, but what does it mean? Meter at the end of a word means
measure
. You use all kinds of measurements each day. How much sugar is needed in the cookies you are baking? Will it be warm enough to leave your jacket at home? How fast are you driving? How much will a bag of apples cost? How much time will it take you to get home from work?
The units of measure in the English and metric systems
Most Americans are taught the English or standard system of measurement, but never get a good dose of the metric system. Lucky for you, it is a much easier system to learn than the English system because all the measurements are
base 10
- meaning that when you are converting from one to another, you will always be multiplying or dividing by a multiple of
10
. This is much easier than trying to do calculations between ounces and pounds, and feet and miles.
Because you may not be used to thinking metrically, it may take a little practice using and working with the metric system before you gain a better understanding of it and become more fluent in the measurement language of scientists (and most non-Americans). I challenge you to sprinkle a little more metric in your life. Maybe read the milliliter measurement on your soda can or glance at the kilometer reading on your speedometer. Being able to picture metric quantities will really help with the rest of this course.
Length
We are going to start with the units of length so we can get back to this word meter that we started out with. The meter is the basic unit of length in the metric system. A meter is a tiny bit longer than a yard. For distances much longer than a meter, you would add the prefix kilo- to make the measurement kilometer. A kilometer is the metric version of our mile, even though it is a bit shorter than our mile. A kilometer is equivalent to exactly 1,000 meters. Any unit that has the word kilo- in front of it is equivalent to 1,000 units. You can attach the prefix kilo- to just about anything. If something takes 1,000 seconds, it takes a kilosecond. If a forest has 1,000 trees, it has a kilotree. .

2_Scientific Viewpoint/Method/SRI
This experiment tested the effect of different amounts of distilled water on plant height. The hypothesis was that if the amount of distilled water is increased, then the height of the plants will increase. The independent variable was the amount of distilled water (50, 100, 150, 200, 250 mL) and the dependent variable was the height of the plants. Ten seeds were planted in each of 5 pots, with pot 3 receiving the recommended amount of 150 mL as the control. The constants were the same type and amount of soil and type of water. Potential design flaws included poorly defined constants and infrequent measurement of plant height.

The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
Make an egg float in salt water
To make an egg float in salt water: add salt to half a glass of water until it is very salty, carefully pour plain water on top so it doesn't mix, and lower the egg in. The egg will sink through the plain water and float in the salty water because salt water is denser than plain water and can support the egg's weight. This demonstrates how density allows objects to float or sink in liquids.
