Today you need a pencil, everything else put away and on the side counter

1. Today you need a pencil, everything else put away and on the side counter • Bell work – Think to yourself, discuss with your table partner, then answer with your table partner “What is matter?” on the yellow lab worksheet. • It is very important that you follow directions today. How are you going to do that? Discuss with your shoulder partner.

2. Think of this lab as a pre-test. I’m not grading you on getting the right answer. I’m grading you on behavior, effort, and completing your work on time.

3. Lab rules • You will go with your partner from station to station. • No eating or drinking. • No horseplay. • When you have completed all stations, go back to your seat and finish the worksheet. • Turn it in today. • Turn it in today.

4. What is Matter? Matter: A substance that has mass and volume (takes up space).

5. Today you need pencil, notebook, agenda, WS from Friday – do not touch the science materials Learning target – • I will be able to measure the mass and volume of objects. Questions – • What is matter? • Anything that has mass and takes up space • What is not matter?

6. What is not matter? • Heat • Light • Sound

7. WAYS TO MEASURE MATTER • Mass – the amount of matter in an object. • Measured in grams (g) and kilograms (kg) • Weight – the force of gravity on an object

8. WAYS TO MEASURE MATTER • Volume – The amount of space an object takes up. • Measured in milliliters (mL) and liters (L) • Also measured in cm3 or m3 (length x width x height) • 1 mL = 1 cm3

9. Go to Volume WS

10. What tools can a scientist use to measure mass? • Electronic Balance • Balances of the late 20th century are usually electronic and far more accurate than mechanical balances. Measurements are read on a digital screen. • Double Pan Balance • A double-pan balance is a scale which has 2 pans that are balanced against each other. The scale functions like a see-saw, with each of the 2 pans attached to a beam over a centered pivot point.

11. What tools can a scientist use to measure mass? • Triple Beam Balance • The triple beam balance is named for the three beams that carry weights. The weights in each of these must always sit in a "notch". They cannot be placed at arbitrary points on the beam. • The middle beam reads only in 100 g increments. • The far beam reads only in 10 g increments. • The weight on the front beam can be placed to read continuously from 0 to 10 grams

12. Procedure for Measuring with a Triple Beam Balance • Place the balance on a flat, solid surface. • Make sure it is “zeroed”. • Place the object to be measured on the pan. Note: If chemicals or liquid is to be measured, protect the balance surface by using a container to hold the liquid or chemicals. Place the container on the pan.

13. Measuring with a Triple Beam Balance Continued • Measure the mass of the container by moving the appropriate weight on the beam. The weight must always sit in a notch. When the correct mass is reached the beam will point to the red line in the middle. • After finding the mass of the container add the liquid or chemical you are massing and find the new mass in the same manner. • Subtract the mass of the container to obtain the mass of your substance.

14. Triple beam balance WS

44. Solid like a rock • http://safeshare.tv/w/HzzpKIXOmc • Youtube video

45. SOLID • Has a definite volume and a definite shape. • A solid will not take the shape of a container. • The particles in solids are packed together, thus keeping it’s shape. They are still moving. • Examples: • Rocks • Desk • Apple

46. LIQUID • has a definite volume but no definite shape. • Takes the shape of its container. • Particles are further apart and moving (pouring water) • Examples • Water • Blood • Milk

47. GAS • Has no definite volume and no definite shape. • Fills a container of any shape or size. • Random groups of particles moving rapidly. • Examples • Air (mixture of different gases) • Water Vapor (water in a gas form) • Gas Behavior

48. Examples of Particles Moving • http://www.harcourtschool.com/activity/states_of_matter/ • Discovery ed video - plasma

49. PLASMA • Plasmas are super-heated gases. • Plasma is an ionized gas. • The atoms are different because they are • made up of free electrons and ions • of an element such as neon (Ne). • Examples • - stars • - lightning • - fluorescent light bulbs • - Neon signs
