Tools of Science Metric System Microscope
The Metric System • International system of measurement • Used to measure – Length – Volume – Mass – Temperature Meter Liter Gram Celsius
Metric Conversions Kilo Hecto Deca UNIT Deci Centi Mili 103 102 10 -2 101 10 -3 Start with the unit that you have and count left or right the number of spaces to move the decimal. For example…. If you have one meter as your “unit” and you want to know how many millimeters…. Count 3 spaces to the left 1. 0 Meters = 1, 000. 00 millimeters
METRIC CONVERSIONS Kilo Hecto Deca UNIT Deci Centi Mili 103 102 10 -2 101 10 -3 • G: Mass L: Volume M: Length C: Temperature • Do the following conversions… – 1000 m. L = ? L – 0. 00056 kg = ? G – 25. 567 m = ? Dm – 0. 05 ml = ? L
Microscope • Compound vs Electron Microscope – What’s the main difference – Resolving power • Magnification calculations – Multiply – Eyepiece X objective) • Function of the various parts… – Copy Table 1 from lab into notebook
Microscope 1. Compound light microscope 1. Light passes through the specimen and uses 2 lens to form an image, magnifies up to about 1000 times. Ü-Magnification: How much larger an image is Ü-Resolving power: ability to distinguish two objects that are close together from one another 2. Electron Microscopes use beams of electrons to produce the image
Compound Microscope Parts
6 Steps of Scientific Method 1. Identify the purpose of your research 2. Gather background information 1. How? 3. Form Hypothesis 4. Conduct experiment 1. Data 5. Analyze data 6. Form conclusions
Scientific Method • What is the purpose of the – Control group (group not treated) – Experimental group (treated group) – Independent variable (what you change or do) – Dependent variable (what you measure) • PRACTICE
• Metric System TEST REVIEW • Memorize the table in the notes – Know prefixes – Know values of prefixes • Know how to do conversions • Scientific Method – Independent (“if” part of hypothesis) / Dependent variable (“Then” part of hypothesis) – Control / Experimental group – Hypothesis – Conclusion • Microscope – Parts – Magnification calculations
