What I have Learned Activity 4: Match Me! A. Match column A with the description in column B. Write the letter of the correct answer before the number. Column A Column B 1. Motion 2. Velocity A. The object's motion has a constant speed. B. The length of the entire path of the object's motion. C. It is a change in position from the reference point. D. Refers to the rate of change in distance per 3. Distance 4. Displacement unit time E. The shortest distance between the object's two positions. F. A quantity which includes magnitude only. 5. Uniform Motion 6. Reference Point G. The frame of reference H. The speed of the object throughout its travel. I. A quantity which includes the magnitude 7. Scalar quantity 8. Vector quantity 9. Average Speed and direction. 10. Speed J. It is the rate of change in displacement.

(b) Manuel is driving at a constant speed. He then slows down to pass an accident. After passing it, he goes back to his original speed and continues driving at that speed. Speed Speed Speed Speed Time Time Time Time Explanation Check

Experimental Procedure Graphing 1. Obtain a 100 mL graduated cylinder. Add 10.0 mL of the liquid to be analyzed to the cylinder and obtain the mass. Write this mass on the results table. NOTE: it does not have to be exactly 10.0 mL. If something other than 10.0 mL is added, note that change on the data table. 2. Continue to add 10mL portions of liquid to the cylinder and obtain the mass each time. Write the cumulative volume, making sure to measure your total volume accurately with each addition, and its corresponding mass in the table. DO NOT EMPTY THE CYLINDER BETWEEN ADDITIONS OF LIQUID. 3. Dispose of the liquid in the appropriate container in the fume -hood. 4. Draw a graph of mass versus volume. Use the guidelines set forth in the example. Make sure the graph takes up as much of the graph paper as possible     Graphing   Increments For the X-axis: Highest X value –Lowest X value/ #of boxes(15) =____ Round up to____   Increments For the Y-axis:Highest Y value –Lowest Y value/# of…

Discuss the language demands included in the lesson on mixing substances in a 5th-grade classroom by Identifying key vocabulary terms students must know in order to master the learning objectives for the lesson based on the below standard and learning objective. Standard Conduct an investigation to determine whether the mixing of two or more substances results in new substances. Learning Objective Given a variety of substances and safety equipment in a classroom setting, students will be able to conduct an experiment to mix two or more substances and observe the results. They will be able to correctly identify whether a new substance has been formed as a result of the mixing, based on observable changes such as color change, formation of a precipitate, or change in temperature, with at least 80% accuracy.

Please correct answer and don't use hand rating

I would help to solve this problem please.

How can you use technology to enhance teaching and learning in a 5th grade classroom for a lesson on mixing substances based on the below standard and learning objective? (Optional: Use the SAMR model to explain the technology integration strategies you plan to use.) Standard Conduct an investigation to determine whether the mixing of two or more substances results in new substances. Learning Objective Given a variety of substances and safety equipment in a classroom setting, students will be able to conduct an experiment to mix two or more substances and observe the results. They will be able to correctly identify whether a new substance has been formed as a result of the mixing, based on observable changes such as color change, formation of a precipitate, or change in temperature, with at least 80% accuracy.

Basic Laboratory Techniques Questions are included in the first image and I was able to include one graph. For the second graph, the x-axis is temperature in Celcius, the y-axis is temperature in Fehrenheit

Please help with questions 2 & 3

Please help with 7&8

If given a value that is plot along x-axis: 1. Find given value along x axis. 2. From this point, trace a straight line vertically (parallel to the y-axis) until it intersects with the line graph. 3. Then, trace a line horizontally (parallel to the x axis) from the intersect to the y-axis. 4. The value of y corresponding to the given x value is where the traced line intercepts with the y- axis. Based upon what you see in the graph listed below, estimate the cost of the fence installation. 450 350 A 300 4 250 200 150 100 50 10 151 20 25 30 35 Cost (in $)

Analyze each statement (A and B) whether they are true or false. Use the choices below in answering each item; A statement A is true B statement B is true C both A and B are true D neither A nor B are true (A) Organic matter application enhances soil texture. (B) Soil texture is a soil physical property that focuses on the whole of the solid fraction of the soil.

Find the slope of the line

After taking multiple measurements of the same sample you have determined that the range of the sample is .06g. This range is primarily useful in determining  A) Precision  B) Rate of growth C) Differences between samples  D) Accuracy

Procedure 1. A crime situation is presented to you. You need to solve the crime by using your senses and given information. 2. Fill in the investigation report correctly. CRIME SCENE A man is found dead in a vac ant lot near his work place. In the crime scene, the SO cO collected different pieces of evidence including two pieces of cloth tainted with unknown stains. The police are hoping that through these pieces of evidence they could find the culprit criminal. or Cloth A Cloth B Pieces of evidence Data and Result Crime: Date: Piece of collected evidence:_ OBSERVATIONS: Cloth A Cloth B Final Findings: Questions 1. Which of the cloth A and cloth B can be used as possible source of evidence in the crime? Why? 2. Which property of matter did you use in making your observation?

How is scientific writing different from the style of writing that you learned in ENG 111?  (Select all that are correct.)   Group of answer choices a. Scientific writing is concise, written in 3rd person, and uses past tense. b. Science writing uses lots of colorful language to describe visual reactions to the experiment. c. Science writing uses lots of personal pronouns (e.g., I, me, we, you, your, our) to show ownership of the results and personal attention to directions. d.Science writing assumes the reader already knows how to do the experiment that is the subject of your paper. e.Science writing may include references that are from peer reviewed sources.

Additional instruction: Your answer must be rounded off to four decimal places. Full solution pls
