Cosmic Radiation Lab Report

During the water drops on a penny, we had an opportunity to make predictions and participate in several trials. Although participating in experiments is important, one way the classroom teacher could enhance the experience would you to have the students come up with a list of testable questions. Once the students have made their list of questions, allow the students to make a prediction, and then test their hypothesis. There were four groups of students each doing their own independent trails and asking their own questions, however, the results were very similar. Although, different techniques were used, the outcomes still allowed each student to have an experience observing surface tension. (See Question 1)

.:6. Design a (hypothetical) experiment that adheres to the Scientific Method. Be sure to include all the necessary requirements at each step and give examples at all of the steps. Start with an observation, whether it’s real or made up, state the null hypothesis, and design an experiment (including an experimental and control group, random sampling, sample size, and reproducibility) that will allow the student to reject or fail to reject the hypothesis, and state the conclusion (20 points.)

•Be sure to write a detailed procedure for each lab design so that the same procedure can be followed accurately by anyone who reads it. Include details on the setup, the control of variables, and how the rate of each trial will be compared.

Each laboratory experiment must be read and carefully studied before coming to the laboratory. This must be done to ensure that each student is thoroughly familiar with the principles, procedures, calculations, and anything else with the exercises may be involved.

For the second part of your assignment, you will apply the scientific method to a real-life situation. You will select a problem that leads to a testable question, similar to the scenarios presented in Part I and explain how you would follow each step of the scientific method to try and answer the question or solve the problem. Note: you are describing only what you would do at each step; you will not be conducting the experiment.

Box 3.2: Why do it this way? is especially relevant, as it considers an important advantage of the experimental method. Chapter 6: No experiments are discussed in this chapter, however, the essay question requires you to discuss the value of experiments. Consider if there are certain aspects of human behaviour and/or performance that cannot be meaningfully investigated using experiments. What are the alternative methods of studying behaviour? Sections 2 and 3 of Chapter 6 are relevant in this respect.

Thesis Statement: I am speaking to you today about the importance, history, and safety concerns of X-rays and the radiation associated with them.

BEFORE CONDUCTING THE EXPERIMENT - You should already have submitted to your teacher an EXCELLENT Investigation Design that included:

19. What is the scientific method, and how does it relate to the science of astronomy?

In Week Three through Week Eight, you conduct scientific experiments in an online lab environment. The content of the labs vary with each week but the structure remains the same. This week, review your Week Three lab instructions and assignment to become acquainted with the essential elements of each lab. You are not required to complete the actual lab this week, but rather to locate various pieces of information about the labs to help prepare for completion of the labs in Week Three through Week Eight.

science -inquiry concepts. In the video clip from lesson 4,minute Students will work together to form hypothesis, observe ,follow procedure ,collect and analyze data, write a conclusion. This lab has four stations, with each stations student were dealing with situation involving phenomenon that they see outside of the classroom, likely on daily basis. so, with each station the Students can be seen using data and their observations as evidence to explain why they were seeing this real-world phenomenon. then students need to answer the lab analysis questions that also connect them with real world. video 2. Furthermore, to help students construct their explanations, I asked questions that push students to make connections to the real world. For example, in video 2, minute , I ask students why organic compounds dose not conduct electricity ? and how about if we try using water and salt ?

4. Test with an experiment – Describe an experiment that would allow you to test your hypothesis from question 3. This description must provide ample detail to show knowledge of experimental design and should list the independent and dependent variables, as well as your control.

Prior to conducting the experiment, the members of the group planned how the practical would be conducted, what variables they were going to measure, and delegated roles evenly between the members. For example, one member was assigned the roles of diluting the Catalase concentration, whilst the other member was responsible for measuring out 50ml of hydrogen peroxide (H2O2). Communication was also vital to ensure that the students knew exactly how the experiment would be conducted. Furthermore, the ideas of each member in the group were valued and taken into consideration with regards to how the investigation should be conducted. As the practical was conducted in a tight space, the students were required to communicate effectively with others to prevent any collision. In addition, cooperation was compulsory, as students were required to share the materials and equipment. All these skills were vital in order for the experiment to be conducted efficiently and coherently within the time

They are given several minutes to explore. Students must find a desirable question to research and conduct the experiment based on their observations.
