2. The Sun’s Diameter Lab

3. The Zoetrope Activity

4. SCIENCE 8 TOPIC 1

5. THE DIFFERENCE BETWEEN AN INFERENCE AND AN OBSERVATION

6. THE INVERTED FLASK DEMO

7. OBSERVATIONS USE THE FIVE SENSES TO OBTAIN DATA WHILE INFERENCES ARE EDUCATED GUESSES MADE BASED ON THE OBSERVATIONS

8. KNOW WHAT THE FIVE SENSES ARE...BE ABLE TO NAME THEM, PLEASE.

9. EVERY MEASUREMENT HAS TWO PARTS: THE QUANTITY – HOW MUCH THE UNIT – WHAT SCALE IS USED

10. DON’T FORGET THE METRIC SYSTEM MEASURE: MASS IN GRAMS, LENGTH IN METERS, VOLUME IN LITERS, AND TIME IN HOURS, MINUTES, SECONDS, ETC.

11. THE DIFFERENCE BETWEEN MASS AND WEIGHT: MASS IS THE AMOUNT OF MATTER IN SOMETHING AND STAYS THE SAME NO MATTER THE LOCATION WEIGHT IS THE MEASURE OF THE PULL OF GRAVITY ON THAT “SOMETHING” AND CHANGES IN RELATION TO HOW CLOSE/FAR ONE IS FROM THE CENTER OF GRAVITY

12. DERIVED UNITS ARE COMBINATIONS OF FUNDAMENTAL UNITS. FUNDAMENTAL UNITS ARE THE BASE MEASUREMENTS IN THE METRIC SYSTEM

13. PERCENTAGE ERROR IS THE AMOUNT YOUR MEASUREMENT IS OFF FROM AN “OFFICIAL” MEASUREMENT

14. PERCENTAGE ERROR FORMULA: FIRST FIND THE DIFFERENCE BETWEEN THE OFFICIAL VALUE AND YOUR VALUE (USE ABSOLUTE VALUES), NEXT DIVIDE THAT DIFFERENCE BY THE OFFICIAL VALUE, AND FINALLY MULTIPLY BY 100

15. OH, TO CONFUSE YOU MORE, YOU ALSO HAVE TO POINT OUT WHETHER YOUR PERCENTAGE ERROR WAS ABOVE (USE A POSITIVE SIGN) OR BELOW (USE A NEGATIVE SIGN) THE OFFICIAL MEASUREMENT

16. FINAL POINTS: FIRST,WHEN CALCULATING NUMBERS, ROUND OFF YOUR ANSWERS TO THE SAME DECIMAL PLACE AS THE ORIGINAL NUMBERS. CONSIDER THE PROBLEM FOUND BELOW:

17. X 3.38

18. SECONDLY, KNOW THAT PRECISION IS HITTING THE TARGET AT THE SAME PLACE ALL THE TIME WHILE ACCURACY IS HITTING THE CENTER OF THE TARGET. YOU WOULD LIKE TO DO BOTH IN SCIENCE
