Presentation on theme: "Observing Like a Scientist?"— Presentation transcript:
1 Observing Like a Scientist? How Do Scientists Make Progress in Understanding the natural world?
2 What does it mean to Observe? There are two main types of observations.Quantitative ObservationQualitative ObservationDeals with a number or amount.ExampleThere are 30 students in this class.Deals with descriptions that cannot be expressed in numbers.ExampleThis gym smells like sweat socks.
3 Name any Quatitative Observations from the short video ARKIVE VIDEOName any Qualitative Observations from the short video.
4 The Study of Life…Inferring How is Structure related to Function?List some characteristics you see on this animal.More on this animalBased on your observations above, which of these items do you think it eats?
5 Past Observations from memory On the way to Las Vegas… Describe the desert you see on the road trip to Vegas.What lives in the desert?
6 Using your new skills… Is a Tumble Weed Alive? Examine the real Tumble weed up close…what do you see?
7 Now…Observe like a scientist With your neighbor…Make a list of both types of observationsChoose any one living organism and list its characteristics. Infertheir functions based on their structure.
8 Activity: Observing up close. Pick a paper labeled with an object from a jar.“rock, insect, leaf, soil, stick, flower.”Go outside with class to collect objects.Using magnifying glasses, observe both quantitativelyand qualitatively. (be sure to measure your item)Sketch and color item in your lab book.Based on your evidence from observing, make inferences,create a hypothesis.Is it alive?How does it support life?How does it appear to survive in its environment?What type of scientist would be concerned with your item?Propose a way to test your hypothesis.
10 Activity: Choose your Title Choose a scientist title.Research the title to findWhat do they study?What kind of technology or tools they use?What kind of experience or training is required?Where they would work?If possible, what kind of money do they make?What other sciences must they know?Provide imagesAny other important information?Prepare a poster or short power pointpresentation to share your findings with the class.For additional job titlesClick image below
11 Example: Microbiologist Expert in : Bacteria, Fungi & VirusesWorks in a lab or clean room, but also works in the field.Studies many things, drinking water, food, forests and rivers, medicines, infectious diseases and even weapons of war just to name a few.Investigates contamination, outbreaksMust spend many years in school earning multiple degreesEtc. , etc. …
12 Big Ideas in Life Science Themes of this class for the year… Organisms are diverse, yet share similar characteristicsGroups of Organisms change over timeThe structure and function of organisms arecomplimentaryOrganisms operate on the same physical principal as therest of the natural world.Science encompasses many fields, we will examine howscience is applied.We will learn how to think and see he world as ascientist, & how to ask scientific questions.
