  1. What Makes Science so Hard? It’s the ridiculous vocabulary!!!! What do you think these words mean? Auscultation Micturation Borborygmus Osculation Cacodyl Oscitancy Emesis Stertor Eructation Wamble Flatus Mastication

  2. What are Some Topics You Would Study in Biology!!!

  3. Watch this video and describe what it may have to do with Biology. • http://video.search.yahoo.com/search/video;_ylt=AiLXpPTFzpxzCqWvSZXCemKbvZx4?p=giraffes+fighting&toggle=1&cop=mss&ei=UTF-8&fr=yfp-t-701 • http://video.search.yahoo.com/search/video;_ylt=AiLXpPTFzpxzCqWvSZXCemKbvZx4?p=giraffes+fighting&toggle=1&cop=mss&ei=UTF-8&fr=yfp-t-701

  10. Prefixes & Suffixes • If you learn certain prefixes and suffixes, you can figure out certain words. Don’t let the vocabulary in science bog you down!! You can figure it out.

  11. What is science? How do scientists work?

  12. What is Science? Science is an organized way of gathering and analyzing evidence about the natural world. I want to teach you this year about the world around. Everyday,I want you to leave here with new knowledge of the world around you !!!!

  13. Two Approaches to Discovering Science 1.Discovery Science – Describes nature. Learning by observations and then describing it. For example – observing DNA and describing parts. 2. Hypothesis-based Science – Explains nature by testing a hypothesis. A hypothesis is proposed from observations then tested. This is where a controlled experiment fits.

  14. Science Methodology Scientists go about solving problems in a certain way. The methodology is always the same. It is called Scientific Method!

  15. Making Good Observations Being a good scientists involves making great observations and then asking questions. Several people can observe the same event but have different explanations. This happens in crime scenes all the time.

  16. Describe what you observe in this picture. DO NOT discuss it with your neighbors.

  17. Observations vs. Inferences An OBSERVATION the act of noticing and describing events or processes. You do it with your 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. An INFERENCE is an assumption or conclusion based on an observation. It is a logical interpretation based on observations and prior knowledge.

  18. Observation Vs. Inferences • When collecting data, as a scientists you must only record your observations and not read anything into what you see. Your inferences are in the conclusion.

  19. Name 2 observations and 2 inferences

  20. Name 2 observations and 2 inferences

  21. Observations Leads to Data Collection • Data collection leads to forming an hypothesis. • Two Types of Data 1. Quantative 2. Qualiative

  22. There is two types of data researchers can collect: • Qualitative data: factual description that do not use numbers. For example, describing the behavior of animals, color of eyes, how mothers react to their young, etc. • 2. Quantitative data: factual information that uses number. For example, counting the number of young, measure how tall something grow, etc.

  23. Qualitative or Quantitative?

  24. Qualitative or Quantitative?

  25. The Scientific Method The scientific method is a process for experimentation that is used to explore observations and answer questions. Scientists use the scientific method to search for cause and effect relationships in nature. In other words, they design an experiment so that changes to one item cause something else to change in a predictable way.

  26. Question: Where do the flies at the butcher shop really come from? Does rotting meat turn into or produce the flies? The scientist then raises a question about what (s)he sees going on!!! Question: How many licks does it take to get to the center of Tootsie roll pop? THE SCIENTIFIC METHOD – a step by step way scientists solve problems. STEP 1: Problem Statement – always written in questions form

  27. Research Step 2: Research – background information about the topic. You have to know what you about you topic before you can experiment. Could be notes, books, internet resources, asking an expert, etc.

  28. This is a tentative answer to the question: a testable explanation for what was observed. IT IS NOT ALWAYS CORRECT! Write a hypothesis for the picture below. Step 3: Hypothesis – a possible answer to the problem statement. Always written as an IF > THEN statement. If I give 2 cups of water to a tomato plant, then it will grow better than plants given more or less water.

  29. Controlled Experiment • Experiment is used to compare an experimental group with a control group to answer a problem • Not all experiments are controlled. You can conduct an experiment without variables. Why is the car not running? You are just solving a problem! • * Contains dependent and independent variables. • Example – king snake vs. coral snake

  30. Procedure – Controlled Experiment Step 4: Procedure – a numbered step set of directions that explains the experimental setup. Includes materials list. Variable– what is being tested, what is different in the experiment (the amount of water given to the plants)

  31. Types of Variable in a Controlled Experiment • Independent Variable – The independent variable is the variable that is manipulated by the researcher.  • *Dependent variable – factors affected by the • independent variable.

  32. Parts of a Controlled Experiment • Constants– all the things you keep the same(same # of plants in a container, same amt of sunlight, same amt of dirt, same amt of fertilizer) • *Control Group: Theexperiment group without the variable being tested.

  33. Tomato Experiment • Problem: How much fertilizer will produce the best tomato plants?

  34. Hypothesis • If a tablespoon of fertilizer is added then the plants will grow the best.

  35. Procedure 1. Obtain 50 plants and pots. 2. Divide into 5 groups. 3. Place 2 cups of the same soil in each pot. 4. Plant the tomato plants. 5. Add ½ cup water every other day for 1 month.

  36. 6. Measure the height of each plant in beginning. 7. Group 1 – no fertizler, Group 2 ¼ tablespoon fert., group 3 – 1 tablespoon, group 4 – ½ cup of fertilizer, group 5 – 1 cup fertilzer.

  37. Questions • Name the variable. • Name the control group. • Name the constants. • Explain why you would use at least 50 plants.

  38. Data and conclusion • Over the next month, you would collect data(height). • Conclusion: at the end of month, see which group grew the best.

  39. What is the Dependent and Independent Variable?

  40. Data and Analysis Step 5: Data and Analysis – explanation of what happened in the experiment. All data collected should be displayed on a data table or on a graph. DATA:factual information gatehred in the experiment.(information or numbers from experiment) What is some data you could collect from these pics?

  41. There is two types of data researchers can collect: • Qualitative data: factual description that do not use numbers. For example, describing the behavior of animals, color of eyes, how mothers react to their young, etc. • 2. Quantitative data: factual information that uses number. For example, counting the number of young, measure how tall something grow, etc.
