Question | Answer |
---|---|
What is Life Science? | The study of living things(biology) Only make OBSERVATIONS in science. |
Ask a question | You could ask a question for every living thing, or organism that has lived. |
life scientists find answers: Who are they? | They are physicians, botanists(study plants), zoologist, microbiologists, science teachers, environmentalists. |
life scientists find answers: Where do they work? | Labs, farms, forest, ocean floors space, hospitals, government agencies. |
Why do scientists study life? Combating disease. | Scientists study life of viruses: polio, aids, tuberculosis and bacteria that cause disease to search for ways to fight them. |
Why do scientists study life? Inherited Disease | Scientists study genes and heredity to learn more about inherited diseases such as cystic fibrosis |
Why do scientists study life? Protecting the environment | Scientists study the environment and organisms habitats to help protect the world for us an all other living things. |
What is the Scientific Method? | A series of steps that scientists use to answer a question or solve a problem. |
1. Ask: Ask a question | By making observations, many questions can arise. |
What is an observation? | It is something you can see, hear, smell, taste or feel. |
What is an inference? | It is something that you think might be true based on the observations. Only make OBSERVATIONS in science. |
Only make _______________ in scince? | OBSERVATIONS |
2. Hypothesis: What is a Hypothesis? | An educated guess about the outcome in a controlled study. A possible explanation or answer to the question. |
A Hypothesis must be___________ | Testable. A Hypothesis must be Testable. |
Hypotheses are stated in the following way? | "If" "then" format. example: If you throw a rock at a window, then it will break. If I pay attention in science class then I will earn a good grade. |
What is an experiment? | An experiment "tests" the hypothesis. After a hypothesis is made scientists will design an experiment to test the hypothesis. |
What is a controlled experiment? | It tests only one factor as a time. All other factors in the experiment are the same(constant factors) |
What are constant factors? | The factors that do not change. They are no being tested, but stay the same. |
What are the two variable types? | Independent Variable(factor being tested) and Dependent Variable(the result, what is being measured) |
What is an Independent Variable? | The factor that is being tested. If I pay attention in science class then I will earn a good grade. Independent Variable is Paying Attention. |
What is a Dependent Variable? | The factor that is being measured in the experiment. DRY, Dependent, Result, analYze. |
What is the experimental group? | The subjects being tested. |
What is the control group? | The subjects that are not being tested. They remain the same. They are used as a comparison against the subjects being tested. |
Collecting Data | From your experiment, data can be collected and organized. |
How much data should you collect? | You should collect as much data as possible to get more accurate results. |
4. Results: What do you with Results? | You put results in a table and graphs. Form these tables and graphs you can see a pattern or trends can be observed. |
5. Conclusion: What is a conclusion? | In the conclusion you decide whether the results from the experiment support the hypothesis. |
What happens if the Hypothesis is not proven by the results and conclusion? | A new hypothesis should be formed or made. |
6. Communicate: Communicate the results. | Share the results with other scientists using a lab report or journal or oral presentation. The information will help scientists discover new questions and answers. |
How do you communicate results? | Share the results with other scientists using a lab report or journal or oral presentation. |
What are the six steps of a scientific experiment? A H E R C C | All Horses Eat Really Crunchy Carrots. (1) A= Ask a Question. (2) H=Hypothesis (3) E=Experiment (4) R=Results (5) C=Conclusions (6) C=Communicate. |
How do I know what it is? What is the Problem? | What am I trying to find out? |
How do I know what it is? What is Hypothesis? | What I think the correct results are? (If/Then) |
How do I know what it is? What is the Experimental Group? | The groups that are receiving the different |
How do I know what it is? What is the control group? | Which group is being used as a comparison? Which group is not receiving the treatment? Which group is receiving the "normal" treatment? |
How do I know what the Independent Variable is? | What is the "treatment"? What will I change in the experiment? What is different among the experimental groups? |
How do I know what the Experiment/Dependent Variable is? | What are the results? What will change because of the independent variable? |
How do I know what it is? Constants | What are the factors that must STAY THE SAME throughout the entire experiment? |
Scientific Method, Step 1? Hint=A | Step 1: Ask-Ask a question(What are you trying to find out?) |
Scientific Method, Step 2? Hint=H | Step 2: Hypothesis-Hypothesis is formed (If..... then statement) |
Scientific Method, Step 3? Hint=E | Step 3: Experiment-Experiment designed (Test the hypothesis) |
Scientific Method Step 4? Hint=R | Step 4: Results - Record/Analyze Data(Data Tables, Graphs, Observations) |
Scientific Method, Step 5? C | Step 5: Conclusion-Conclusion(Hypothesis Rejected or Supported.) |
Scientific Method, Step 6, C | Step 6: Communicate-Communicate Results (presentation, Lab Report). |
