DO NOW Cedillo Directions: Fill in your Weekly Do Now sheet, then answer the prompt. Objective Students will be able to distinguish between an observation and an inference. Do Now Prompt In the picture to the right…. What do you OBSERVE (see) and what can you INFER (predict) Is happening? Sept. 3rd, 2013 Sept 4th ESSENTIAL QUESTION: What is the difference between an observation and an inference? AGENDA: -Use observations and inferences to create a model of the inside of the “Mystery Box” -Define observation and inference -Learn how to create a concept map Mystery Box – Pg. 7 OBSERVATIONS INFERENCE -RECORD WHAT YOU OBSERVE IN THIS BOX -USE YOUR OBSERVATIONS TO CREATE A DRAWING OF WHAT YOU THINK THE INSIDE LOOKS LIKE ESSENTIAL QUESTION: What is the difference between an observation and an inference? OBJECTIVE: -Distinguish between an observation and an inference. DO NOW Objective SWBAT distinguish between a descriptive, comparative, and experimental investigations. Prompt Using observations, describe your teacher. What inferences can you make about your teacher from your observations? Reminders: --Enter quietly --Sharpen pencils and have materials out and ready *BEFORE* bell rings --Be in seat working on Do Now with voice level 0 when bell rings --Make sure homework is written in agenda for this week. Today’s Agenda ESSENTIAL QUESTION: What is the difference between a descriptive, comparative, and experimental investigation? Agenda: -Use observations and inferences to conduct and descriptive investigation of Turk’s Cap. -Conduct a comparative investigation of Turk’s Cap and the Siberian Iris. -Look at an example of an experimental investigation -Fill out a Mind Map to organize information about scientific investigations. Descriptive Investigation Dr. Damian Elias: http://nature.berkeley.edu/eliaslab/# How do animals communicate? Descriptive Investigation Dr. Damian Elias: http://nature.berkeley.edu/eliaslab/# Scientists from the Elias Lab use descriptive investigations to understand how jumping spiders communicate.

Make observations of two or more things using 5 senses and scientific tools. Create your own Investigation • I will assign your table either a descriptive or comparative investigation. • You must come up with a question you would like to answer in your investigation. • You must come up with the way your will carry out your investigation. Experimental Investigations Dr. Rachel Paige: http://research.yerkes.emory.edu/Young/larry.html What are the risks when finding a mate? Experimental Male Simple Call Male Complex Call Female Frog Bat Mind Maps In science, there are three types of investigations Can be Descriptive Comparative Experimental Will Include a hypothesis and prediction Observe the effect of the independent variable on the dependent variable DO NOW (Pg. 6 in journal) Objective SWBAT distinguish between a descriptive, comparative, and experimental investigations. Prompt What is the difference between a descriptive, comparative, and experimental investigation? Reminders: --Homework due today. Make a pile in the aisle. ESSENTIAL QUESTION: How do you design an experimental investigation? OBJECTIVES: -Design an experimental investigation to test a question about Turk’s Cap and the Siberian Iris. Experiments Testable Question: Do plants grow taller under a green, red, blue, or natural sunlight? Can be turned into a hypothesis… IF_______________________, then ______________________________. Hypothesis • A prediction that answers the question in an experiment. • Testable Question: Do plants grow taller under a green, red, blue, or natural sunlight? Can be turned into a hypothesis… If I place plants under green, red, blue, and natural sunlight , then the plant under the red light will grow faster. Variables and Controls Independent Variable: Something the scientist changes during the investigation. Dependent Variable: Something that changes and can be measured as a result of the independent variable. Control/Constant: Something that stays the same in an investigation. Variables Testable Question: Do plants grow taller under a green, red, blue, or natural sunlight? The color of the light is the ___________________ The plants height is the ______________________ Design your own experiment • With your shoulder partner: – Come up with a question that can be tested – Form a hypothesis that gives a prediction that answers that question – Identify variables and control – Be prepared to talk about how you would set up your experiment, and what kind of data you would collect. If I put a plant under a blue light and another under a red light, then then plant under the blue light will grow faster. The type of plant The color of light The plant’s height Plant A: 6 cm Plant B: 12 cm Descriptive, Comparative, or Experimental? • On your dry erase boards, choose whether the experiment read by the teacher is a descriptive, comparative, or experimental investigation. Descriptive vs. Comparative vs. Experimental Use your cards to identify the type of investigation Descriptive Comparative Experimental Descriptive vs. Comparative Jane Goodall began studying Chimpanzee’s in the 1960’s. Jane moved to Africa and began making close observations of Chimpanzees in the wild and in captivity. Because of her investigations we now know that chimpanzees are meat eaters, use tools, and hunt Capuchin monkeys for food. Descriptive vs. Comparative In the 1670’s Antony van Leeuwenhoek was the first person to look at living cells under a microscope. Leeuwenhoek viewed pond water under a microscope and discovered a world of small single celled creatures. Descriptive vs. Comparative Jane and Sarah are involved in the student health club. They are concerned about rumors that girls are concerned about their weight. They are wondering if this is a problem with girls at every grade. Both girls make careful observations in the cafeteria during 6th and 7th grade lunch. The girls put their finding together so they can present it to their teacher. Descriptive vs. Comparative Max wants to help plant the school garden. He is interested in planting species of plants and flowers that will attract birds and butterflies. Max decided to go to the local city garden. Max made careful note of the animals that visited the gardens. When he was finished observing he recorded the names of the plant species that were planted there. Descriptive vs. Comparative Jason is on the track team, and he wants to run faster. While watching TV, he sees two different commercials for energy drinks that promise to give you more energy. He times himself running 1 mile on Monday without any energy drink. Then he times himself running 1 mile after drinking 16oz of Red-Bull one week later. Finally, he times himself running 1 mile after drinking 16oz of Monster energy drink a week later. After analyzing the data, he infers that energy drinks do not make him run faster. Descriptive vs. Comparative Mark works for the National Forest Service. He is concerned about the effects of forest fires on the species plants and animals in the mountains where he works. Mark decided to visit the north side of Sleeping Ute Mountain where fires were very rare. He recorded observations of the plants and animals. Mark then traveled to the south side of the mountain that had recently experienced a wild fire (cause by lightening). Mark recorded his observations of the plants and animals there.
