The document discusses measures of length including different units like meters, centimeters, kilometers. It explains that meters are the standard metric unit and provides conversion facts between units like 1 km = 1000 m. Learners are instructed to practice converting between units of length like meters to centimeters using multiplication or division based on the conversion facts.
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.

Scientific notation powerpoint
Scientific notation is a way to write very large or small numbers as a product of a number between 1 and 10 and a power of 10. To convert a number to scientific notation, the decimal is moved to place one non-zero digit before the decimal point, and the number of places the decimal is moved determines the exponent of 10. Numbers greater than 1 have positive exponents, while numbers less than 1 have negative exponents. Converting back to standard form moves the decimal right for positive exponents and left for negative exponents by the value of the exponent.

Life history in qualitative research
This document discusses life history as a qualitative research method. It explains that life history involves collecting personal narratives from individuals to understand their experiences. Key elements include a researcher who conducts interviews, an informant who shares information, and tools like interview guides and historical records. Life histories can be analyzed statistically, through computer software, by developing typologies, and through various forms of thematic analysis. The method has advantages like providing an in-depth understanding of a person's social and economic experiences, but also disadvantages such as difficulty generalizing findings and aggregating data due to typically small sample sizes.
Qualitative research techniques
The document discusses various qualitative research techniques including observation, focus groups, depth interviews, and projective techniques. Qualitative research involves observational techniques or unstructured questioning to understand behaviors, opinions, and motivations. Focus groups involve moderated group discussions with 8-12 screened participants to understand perceptions and generate ideas. Projective techniques use ambiguous stimuli to indirectly reveal respondents' views through activities like word associations, sentence completions, and cartoon interpretations. While qualitative techniques are suitable in theory for Asia-Pacific countries, cultural factors like preference for numbers over opinions and reluctance to discuss sensitive issues pose challenges to their practical use in most Asian markets.
Presentation of science (matter)
Matter is anything that has mass and occupies space. It exists in three main states: solid, liquid, and gas. The state depends on how tightly or loosely the particles are packed. Solids have a fixed shape and volume as particles are tightly packed and vibrate in place. Liquids take the shape of their container but maintain a fixed volume as particles can move past one another. Gases have no definite shape or volume as particles are very far apart and move freely. Water can change states by adding or removing heat, going from solid ice to liquid to gas vapor.
Qualitative Research Methods
This document provides an introduction to qualitative research methods in information sciences and technologies. It discusses the differences between quantitative and qualitative methods, noting that while traditionally seen as incompatible, they are actually complementary.

Grade 9 U0-L3 - Measurement
This document discusses measurement and units in science. It begins by defining measurement as reading tools like watches, scales, and thermometers. Standards of measurement are compared to a standard unit using tools. The metric system and SI units are introduced, with prefixes and conversions between units. Equalities show the same measurement in different units. Conversion factors relate different units, and steps for unit conversions in problems are outlined.
Metric conversions 2010
1. The document discusses the metric system and metric conversions using prefixes and a "ladder method".
2. It explains that metric prefixes are based on powers of 10, making units either 10 times bigger or smaller than the next step.
3. The ladder method is used to perform metric conversions by counting the number of steps between units and moving the decimal place the same number of steps.
Unit 1
This document provides information about measurement and units of measurement. It discusses the tools used for measurement including vernier calipers and micrometers. It defines key terms like accuracy, precision, and significant figures. It also covers creating distance-time graphs and using them to determine speed and velocity. Examples are provided to demonstrate how to calculate speed from a distance-time graph and how the graph would look for an object that changes speed or stops during its motion.
Measurement&Conversions
The document discusses measurement units and the International System of Units (SI or metric system). It explains that the SI system standardized units to ensure consistency, using meters, kilograms, and seconds as base units. Derived units are built from the base units, such as square meters for area and cubic meters for volume. Liquid volumes are commonly measured in liters, which are equivalent to cubic meters for liquids and gases.
Measurements & units
This document provides an overview of measurement and the metric system. It defines key terms like units, base units, derived units, and prefixes. It then explains the metric units for length, mass, volume, temperature and other common physical quantities. Conversion methods between metric and imperial units are presented, including dimensional analysis. The metric system is described as the universal standard for measurement in science.
Metric conversions 2010
The document outlines a lesson on metric conversions, including reviewing the base metric units of length, volume, and mass. It explains the metric system prefixes and how they relate to powers of 10, allowing conversions between units by moving the decimal point left or right. Examples are provided for converting between meters and kilometers, grams and milligrams, and liters and milliliters using the "ladder method" of counting jumps between prefixes.
Metric system conversions 2010
Here are the steps to convert 5,720 km to cm:
1. Write 5,720 km with the correct prefix (kilo) above it: 5,720 k
2. Move the decimal place the correct number of spaces to the right (from k to c): 5,720,000
3. Write the correct prefix (centi) above the final number: 5,720,000 cm
So, 5,720 km = 5,720,000 cm
To convert 23 mg to dag:
1. Write 23 mg with the correct prefix (milli) above it: 23 m
2. Move the decimal place the correct number of spaces to the left (from m to da):
Metric Mania Powerpoint
The document provides instructions on using the ladder method for metric unit conversions. It explains that the ladder method involves determining the starting point, counting jumps between units, and moving the decimal the same number of places. Examples are given converting between kilometers, meters, liters, grams, and other metric units. Practice problems are included for the reader to complete conversions using the ladder method.
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.
Metricconversion
This document provides information about metric conversions. It introduces common metric units like meters, grams, and liters. Metric conversions are necessary when a measurement is too large or small for the unit being used. The document teaches the "stair-step method" for metric conversions using a chart that lists metric units in order from largest to smallest (kilo to milli). It involves moving up or down the "stairs" by multiplying or dividing by 10. Some example conversion problems are provided for practice. The document emphasizes that metric conversions are easy and only require knowing how to count to six and knowing left from right.

How Did Life Begin
Stromatolites, formed by cyanobacteria, were some of the earliest signs of life on Earth around 3.5 billion years ago. Cyanobacteria in stromatolites were able to use carbon dioxide and produce oxygen through photosynthesis, beginning the process of oxygenating our atmosphere around 2 billion years ago. The document provides background on stromatolites and their role in producing oxygen through photosynthesis, and asks students to draw a timeline showing the beginning of life on Earth and oxygen production over time.
Characteristics Of Life
This document discusses the characteristics of life. It begins with an agenda that includes reviewing homework on the characteristics of life and having students practice identifying examples as living, non-living, or dead. The document then lists and describes the main characteristics of life, including being made of cells, organization, growth, reproduction, response to stimuli, requiring energy, homeostasis, and adaptation. Examples are provided for each characteristic. Students are then asked to identify which characteristics are shown in various video examples and assigned homework on how they think life began on Earth.
Measurement Writing
The document outlines an agenda for a lesson on writing about measurements. It includes a 5 minute "Do Now" activity where students write out measurement terms, a 15 minute practice writing sentences with measurements, and a 10 minute review quiz. It concludes with assigning a homework where students must write whether examples are alive or not alive based on if they move, eat, or breathe.
Measurement Lab
The document discusses different measurement units and how to calculate mass, length, width, and volume. It provides examples of measuring the mass of objects in grams and liquids by subtracting the mass of an empty container. It also demonstrates how to calculate the volume of an object by multiplying its length, height, and width. Students are instructed to work in groups measuring the mass and length of objects and volume of other objects.
Inference and Observation Scienetific Method And Lab Safety
The document outlines an agenda for a science lesson that includes a vocabulary quiz, a lesson on making inferences versus observations, and an activity where students work in groups to analyze pictures and determine if what they see is an observation or inference. It also lists lab safety rules and homework assignments related to making observations and inferences.
Independent Dependent Variable
The document discusses independent and dependent variables in experiments. It provides examples where the length of a paper airplane and the amount of sunlight are independent variables that can be controlled, while the distance the airplane flies and the growth of a plant are dependent variables that cannot be directly controlled. It explains that the independent variable is the factor that can be deliberately changed or controlled in an experiment, while the dependent variable is the measurement that changes in response to the independent variable but cannot be controlled.
Conversions
The document provides examples of estimating the mass and length of different objects like an owl, laptop, pencil, metro card, and milk. It then discusses metric system prefixes like kilo, hecto, deka, deci, centi, and milli and their meaning in terms of units. It asks the reader to convert between kilometers and meters and asks how many jumps it would take to equal a certain number of meters. Finally, it provides practice problems for converting between grams and milligrams, liters and milliliters, and centimeters and millimeters.
Quiz 9 22 Review
The document is a quiz review that asks questions about length and width measurements of an airplane, identifying observations versus inferences, independent and dependent variables, types of charts and graphs, hypotheses, and factors to control in an experiment. It contains 8 multiple choice questions testing concepts in scientific experiments and data analysis.
Hypothesis
This document discusses forming a hypothesis by making observations and inferences from experiments with variables. It explains that a hypothesis is a guess about the relationship between an independent variable that is controlled and a dependent variable that is observed but not controlled. Three examples are given where observations are made, inferences are drawn, and hypotheses are formed about how changing the independent variable affects the dependent variable.
