  2. Sept. 3 Pg. 2Today’s Goal: Scientific Inquiry Skill: Observation = How is an observation different from an inference? Warm Up: What do I observe? Writedownyour observations.

  7. Observation- information gathered using one or more of the five senses. • Observations: • People wearing helmets • Two people in green and white • One person in in black • One person wear stripes • Persons arms out like a T with a • football in hand • Persons arms above their head

  8. Qualitative observation- deals with descriptions that can be observed but not measured • Examples-Colors, textures, smells, tastes, appearance, beauty, etc

  9. B A C

  10. Quantitative observation- an observation dealing with numbers that can be measured • Examples: Length, height, area, volume, weight, speed, time, temperature, humidity, sound levels, cost, members, ages, etc.

  11. B A C

  12. Inference- an interpretation of one or more observations. • Inferences: • The playier in black scored a touchdown • #81 is tackling the player in black

  14. Qualitative or Quantitative? • Chemical A and chemical B reacted creating bubbles. • The chemical reaction realeased 10 joules of heat into the environment. • The beaker contained 10 mL less water that the previous day. • The brown rock is heavier than the black rock. • The bear has a number 3 shaved into its fur.

  15. Scientific Inquiry Skills Review One of the most important skills in science is the use of our five senses or making observations. Most of the time we think of observing as something we do with our eyes; when we see something, we observe it. However, all five of our senses can be used to make observations: sight, hearing, taste, touch, and smell. A good scientist is observant and notices things in the world. He or she notices what’s going on in the world and becomes curious about what’s happening?

  16. We can make two kinds of observations: Qualitative or Quantitative Qualitative Quantitative can be expressed using numbers: can be measured or counted. Tools are often used to collect quantitative data quantity, temperature, mass, and length. rulers, balances, graduated cylinders, beakers, and thermometers. • data is information that is hard to measure, count, or describe in numbers • Examples are colors, tastes, and smells

  17. Quantitative or Qualitative? Why? • 1. The cup had a mass of 454 grams. • 2. A multicolored building on New Bern Street is taller than the trees. • 3. The sidewalk from my house to my friend’s house is 100meters long. • 4. I observed since the season has changed the temperature outside has decreased.

  18. Suppose your friends went to the pool at noon on a warm day. They saw some black and white birds. Which of the following statements are observations and which are inferences? Write your answer with either the letter “O” for an observation, or the letter “I” for an inference. 1. ____________ It is summertime. 2. ____________ It is daytime. 3. ____________ They saw birds. 4. ____________ They saw pigeons. 5. ____________ They went swimming. 6. ____________ One friend’s name was Bob. 7. ____________ It was a warm day.

  19. Write a definition for inference.

  20. 1) Sandra added 4 drops of vinegar to the baking soda. __ 2) The liquid in the graduated cylinder was thick and yellow and smelled putrid. ________________________ 3) The leaves on the maple tree were brown and fragile at the end of October. ________________________ 4) The planet Neptune is extremely cold on its surface. __ 5) There are twelve marshmallows left in the bag. ______ 6) Jessica’s sunburned arms are bright red and starting to blister. _ 7) The ocean water tastes salty in my mouth._________ 8) The pond is dark green in color and covered with a slimy mess of plants and algae. _____________________ 9) The basketball bounced 145 cm off the ground, while the soccer ball bounced only 45 cm. _____________________ 10) Kevin’s toothpick bridge was three meters long and held two bricks.

  21. Homework pg. 1 • Part A: Draw a grid: 5 columns, 4 rows • Part B: • 1. Draw, cut, or print out a picture. Record 5 quantitative and 5 qualitative observations in your grid. • 2. Choose an object at home. Record 5 quantitative and 5 qualitative observations in your grid.
