The ABC’s of Science What is Physical Science What are we learning this year The ABC’s of Science What are the ABC’s of Science

Kelley, Dave, Field Editor has reference to this Academic Journal, PHwiki organized this Journal The ABC’s of Science Day 1: Intro to Physical Science Metric Introduction Metrics: Length What is Physical Science Physical science is the study of matter in addition to energy. The universe is composed of matter. Your body, this paper, in addition to your desk are matter. In physical science, you will learn the properties of metals, water, air, in addition to many other kinds of matter. What are we learning this year We will be looking at 3 different areas of physical science: Chemistry Physics Space Science

Why do I have to know this stuff Imagine humans when they first had fire, when they first made wheels, when they first established where they were going by looking at the stars. How did the things we consider basic – heat, light, navigation, transportation, entertainment – ever come to be The answers all touch on physics in addition to chemistry. Chemistry tells us how to make things in addition to what things are made of. Physics tells us how in addition to why things move. The ABC’s of Science Be as long as e we start with Chemistry, we need to cover a few basic, but very important, areas of science. I call them the ABC’s. In other words, without the ABC’s, nothing makes sense. What are the ABC’s of Science The Metric System Safety The Scientific Method

Let’s talk Metric Here in America we use ye olde English system: foot, yard, in addition to mile. However, MOST countries use another system called the International System of Units or the SI system (which st in addition to s as long as Système Internationale d’Unités) This is the modern as long as m of the metric system. It all depends on the foot! Numbers in addition to units are used to make measurements. The distance from your desk to my desk could be 25 shoe lengths or 30 shoe lengths. It depends on how big the shoe is. Think of Shaq’s foot versus Mini-Me. It all depends on the foot! In order to measure accurately, we have to use st in addition to ard units. In other words, everyone has to use the SAME system or units. Otherwise, it just gets confusing. A st in addition to ard is a fixed quantity used by everyone when measuring.

Advantages to the Metric System There are two advantages to using the metric system: It helps scientists share & compare their results & observations. If I conducted an experiment here in America, even a scientist in Zimbabwe would be able to underst in addition to my measurements. All units are based on the number 10. Changing from one unit to another is easy! 1. Metric Measurement Math-terpiece Theater BrainPop: Metric vs. Customary

Still Confused OK, let’s get this as simple as we can. We are going to look at all of our metric measurement units as two-part words. The first part is the PREFIX. The second part is the type of UNIT. Part 1: the PREFIX Here are the main prefixes You need to memorize these, since you will see them as long as the rest of your life! Here are the rest of the prefixes you’ll have to know all of these 🙂 just kidding!

Part 2: the UNIT Here are some of the most important units, in addition to you need to memorize these too. Try this 1 kilometer is equal to -1000- meters. kilo-meter prefix = kilo or 1000 unit = meter, measuring distance There as long as e: 1 kilometer = 1000 meters. 5 kilometers is equal to – meters 5 x 1000 meters = 5,000 meters 10 kilometers is equal to – meters 10 x 1000 meters = 10,000 meters Later, we’ll practice converting from one to another. Try this What unit would you use to measure each of the following Water in a bottle Liter The distance from my classroom to the bathroom Meter The amount of heat in the classroom Kelvin or Celsius How much matter is in a paperclip Gram

2. If only American Chopper used the metric system Metric System: Length The meter (m) is the SI unit of length. A meter is about the distance from a doorknob to the floor. A driver golf club is also about a meter in length. The meter is divided into 100 equal parts called centimeters (cm). There are 100 centimeters in a meter: 100 cm = 1 m An even smaller unit is a millimeter (mm). The prefix “milli-” means 1/1000, so 1000 mm = 1 m 10 mm = 1 cm

Long distances are measured in kilometers (km). In the US, we measure speed by miles per hour (mph). In most other countries, they measure in kilometers per hour (km/h). You try it! Name 3 things that are about one meter long. Golf Club, Chair, Flag, 6th graders Name 3 things that are measured in centimeters Paperclips, babies, toes, fingernail Name 3 things that are small enough to be measured in millimeters Camera film, pencil lead, wire diameter, insects

You Try It! Arrows A, B, & C are all pointing to a particular place on a meter stick. Name the value & include units. Point A = 49.4 cm or 494 mm Point B = 50.5 cm or 505 mm Point C = 52.0 cm or 520 mm You try it! What is the most appropriate unit as long as a scientist to use to measure the following Distance from San Diego to New York km Length of your eyelash mm Distance from A306 to the office m Length of your arm cm Height of this building m Length of a grain of salt m You try it! Practice Measuring Measure the length of this paper in cm & mm. – cm & – mm Draw a square with sides measuring 11cm. Measure the height of your desk from the floor to the top in meters & centimeters. – cm & – m Measure the length of your desk in meters & cm. – cm & – m

Smile Lab Time! Today you’re going to measure your smile with a piece of string, in addition to then tape that string to your table’s paper. When your table has completed the measurements & taping come up front to record what the measurements were, so that your classmates can record those lengths. Be sure to complete the graph & conclusion of your lab. EVERYONE needs to complete a lab write up.
