Our Senses help us identify matter • Sight, Touch • Sight and Touch provide the most information to our brains about matter • Our senses can also be deceived -> 1| 3 Section 1. 3
Are the gray horizontal lines parallel or do they curve? How will you support your hypothesis?
• Sensory Limitations – can be reduced by using measuring devices • Instruments extend our ability to measure and learn about our environment and the matter in it.
Matter is anything that has mass and volume • Matter can be measured and described
What are examples of measurements you see in the world?
Examples of measurements • Length • How long is it? (miles, inches, kilometers, centimeters) • Instrument: Ruler, meter stick, tape measure • Volume • How much space does it fill? (Liters, gallons, quarts, milliliters) • Instrument: Graduated cylinder, measuring cup • Mass/Weight • How much does it weigh/How much stuff is in it? (pounds, ounces, grams, kilograms) • Instrument: Triple Beam Balance, scale • Time • How old is it/how long does it take (seconds, minutes, years) • Instrument: clock, stopwatch, calendar • Speed • How quickly does it travel a certain distance? (miles/hour, km/h, meters/sec) • Instrument: clock and ruler
Measurement in Science • We will use a variety of tools in class to help us describe matter
We use metric measurements in science class. • Why? • It’s easier to convert (m to cm vs. yards to feet) – no fractions! - All but three countries use metric Non-metric countries: USA, Myanmar, Liberia
Today • Use the Science World Magazine to identify ways in which matter is being measured.
Homework • Identify things being measured in your everyday life. • Find at least 10 items and their METRIC measurements by tomorrow. • Metric: grams, liters, meters, centimeter, kilometers, kilograms, kiloliters, milliliters
