Presentation Transcript

  1. observations vs inferences (and Quantitative vs. Qualitative )

  2. Scale for learning

  3. Making Observations • You have 30 seconds to remember as much detail about the items on the next page. • The more detail the better. • At the end of 30 seconds, record everything that you remember from the slide. • You may not write while the pictures are still on the screen!

  4. Times Up! Write down as many items with as much detail as you can remember!

  5. Observations • A good scientist is observant and notices things in the world • A good scientist is curious about what is happening around them • Observations are facts, not opinions. • Observations are made using your five senses or using tools.

  6. Observations – two types • Two kinds of observations: • Qualitative: Uses your five senses see, smell, taste, hear, and touch. • Quantitative: Requires you to measure, count, etc.

  7. Qualitative vs. quantitative Qualitative: what we can see, hear, feel, smell, and/or taste • Qualitative observations are descriptive Quantitative: what we can measure and count (amounts, length, volume, mass, temperature) • Quantitative observations are numerical Video Link 1: https://www.youtube.com/watch?v=-S2EiPD4-W0 Video Link 2: https://www.youtube.com/watch?v=dwFsRZv4oHA

  11. inferences • Inference: Drawing a conclusion based on data, observations, and evidence. • The process of drawing a conclusion from given evidence. • NOT the same as an observation • Making Inferences Video Clip (5:30) – watch video clip and stop along the way to state observations and make inferences based on the observations made.

  13. Making Inferences

  14. Cat’s in the bag lab directions • There are 8 bags that will be rotating around the science lab groups. • Each station has a sealed bag with a school item in it (an item that was found in this classroom) • Your job is to make QUALATITIVE observations (What do you feel? What do you hear?) • Your job is to make QUANTATIVE observations as best you can through the sealed bag. (How many items inside?) • Remember: Be detailed and thorough in your observational recordings of the mystery cat bags! • After you gather all your observations and data, you will make a HYPOTHESIS as to what is inside by INFERRING about how the observations you made are related to a classroom object/item.

  16. Observations – Using Touch and Sound only Qualitative Observations • What does it feel like? • What does it sound like? Are the items in the bag all of the same kind of items or are there different ones? What proof do you feel/hear? Quantitative Observations • How many items are in the bag?
