PLEASE HELP Science Test Friday Study Guide?
I have 1 to 22 already but I am stuck now I have to have this completed and correctly for my study guide. I have a C right now I need an A on this test to bring it up to a B or I stay on restriction please help I have been on restriction for 2 weeks now I want to cry I don't understand science I am terrible w/ it.
Matching
For questions 22–31, Place the letter of the term that best matches the situation.
Terms:
A. Variables
B. Analysis
C. Experimental group (warmer or colder than body temperature)
D. Conclusion
E. Data collected
F. Controlled conditions
G. Preliminary observation
H. Control (closest to body temperature)
I. Hypothesis
J. Question
22. Materials feel warm or cool to the touch
23. Wood
24. Metal, Styrofoam
25. Will different surfaces affect the melting rate of an ice cube?
26. Different counter surfaces
27. If an ice cube is placed on the surface of each material, then the material that feels warmest will melt the ice cube the fastest.
28. Measurement of melting time
29. The material that felt the coolest melted the ice the fastest.
30. Same sized ice cubes, flat surfaced materials and equal mass
31. The materials tested were at room temperature. Since body temperature was warmer than the room temperature, heat will be lost to the material in direct relationship to its density. Styrofoam, as the least dense, felt closer to body temperature and didn't lose much heat. However, it was the best insulator and maintained the ice cube the longest.
True or False 32-35
32. In the above experiment, the hypothesis was not right. This makes the experiment a failure. True or False
33. When a hypothesis is not correct a good researcher would rewrite the hypothesis and then re-test it. True or False

35. A successful experiment often leads to more questions. True or False
36. List the basic steps of the Scientific Method in order
I am not 100% sure if I am correct please correct if wrong
1. finding a question
2. form the hypothesis
3. do an experiment
4. analyze results
5. draw conclusions
37. Think of one or two products sold in this country that are tested, using the scientific method, before they are placed on the market and then later found to be dangerous. Explain how faulty or incomplete testing of a product can become a threat to health and give two specific examples.
Nobody is going to do all this work for you on here, they always say they don't do your homework and they just HELP.
i can definately try though, some are veryyy self explanatory. i know how you feel with the whole "grounded" thing
OMG I am stuck on the same exact problems, so difficult!
To help you with your science test study guide, let's go through each question and find the correct answers step by step.
Matching:
22. Materials feel warm or cool to the touch.
To match the situation, we need to find a term that relates to the sense of touch and temperature. The appropriate term is "G. Preliminary observation."
23. Wood.
This question is asking for a match for the material "wood." The correct term is "F. Controlled conditions." Wood is often used as a control in experiments since it does not conduct heat as well as other materials.
24. Metal, Styrofoam.
The materials listed here are "metal" and "Styrofoam." The matching term is "A. Variables." Metal and Styrofoam are the variables being tested in the experiment.
25. Will different surfaces affect the melting rate of an ice cube?
Here, the question is whether different surfaces affect the melting rate of an ice cube. The corresponding term is "J. Question" as it directly pertains to the experiment's objective.
26. Different counter surfaces.
This phrase refers to the variety of counter surfaces being used. For this situation, the matching term is "C. Experimental group (warmer or colder than body temperature)." The surfaces are part of the experimental group being tested.
27. If an ice cube is placed on the surface of each material, then the material that feels warmest will melt the ice cube the fastest.
This statement presents a hypothesis. The term that matches this situation is "I. Hypothesis" since it is a proposed explanation for the experiment.
28. Measurement of melting time.
The phrase "measurement of melting time" refers to the data collected during the experiment. Therefore, the matching term is "E. Data collected."
29. The material that felt the coolest melted the ice the fastest.
This statement is a conclusion drawn from the experiment. The appropriate term is "D. Conclusion."
30. Same sized ice cubes, flat surfaced materials, and equal mass.
This sentence identifies the controlled conditions of the experiment. Therefore, the matching term is "F. Controlled conditions."
31. The materials tested were at room temperature. Since body temperature was warmer than the room temperature, heat will be lost to the material in direct relationship to its density. Styrofoam, as the least dense, felt closer to body temperature and didn't lose much heat. However, it was the best insulator and maintained the ice cube the longest.
This statement describes the outcome of the experiment. The corresponding term is "D. Conclusion."
True or False:
32. In the above experiment, the hypothesis was not right. This makes the experiment a failure. False.
The statement is false because even if the hypothesis is not correct, it does not make the experiment a failure. The experiment can still be successful in providing valuable data and insights.
33. When a hypothesis is not correct, a good researcher would rewrite the hypothesis and then re-test it. True.
This statement is true. When a hypothesis is not correct, it is necessary to revise the hypothesis and conduct further tests to refine it.
34. A successful experiment is one that can be analyzed and explained, even if the answer is not what the researcher expected. True.
This statement is true. A successful experiment is not solely determined by whether the result matches the researcher's expectations but rather if the data can be analyzed and explained objectively.
35. A successful experiment often leads to more questions. True.
This statement is true. A successful experiment can provide new insights and raise further questions for future research.
36. List the basic steps of the Scientific Method in order.
The correct order of the basic steps of the Scientific Method is as follows:
1. Ask a question.
2. Form a hypothesis.
3. Conduct an experiment.
4. Analyze the results.
5. Draw conclusions.
37. Think of one or two products sold in this country that are tested using the scientific method before they are placed on the market and later found to be dangerous. Explain how faulty or incomplete testing of a product can become a threat to health and give two specific examples.
To answer this question, you'll need to think about products that have been found to be dangerous due to faulty or incomplete testing. It's important to note that products being tested using the scientific method before being placed on the market is a standard practice. However, in some cases, flaws in the testing process can lead to potential health risks.
Two examples of products that were found to be dangerous due to faulty or incomplete testing are:
1. Thalidomide: In the 1950s and 1960s, thalidomide was prescribed as a sedative and anti-nausea medication to pregnant women. However, insufficient testing failed to identify the harmful effects it had on fetal development, resulting in severe birth defects.
2. Vioxx: Vioxx was a prescription painkiller that was recalled in 2004. Inadequate testing failed to identify the increased risk of heart attacks and strokes associated with its use.
Faulty or incomplete testing of products can become a threat to health because it may not accurately identify potential risks or side effects. This can lead to the release of products that, unknowingly, could harm consumers or have negative consequences. Therefore, it is crucial to conduct thorough and rigorous testing to ensure the safety of products before they are available to the public.
Remember, studying and understanding science takes time and practice. Don't be too hard on yourself. Take small steps, seek clarification when needed, and ask your teacher for extra help or additional resources if necessary. Good luck with your test!
