1 1 Motion Name: pd date

2 Quick Write Focus Question: draw motion use words to describe motion (do not use move, movement, etc)

3 Motion Notes definition symbol formula motion position initial position final position distance delta reference point independent variable dependent variable

4 Flight Distances Directions Calculate the distance of each flight, using the distance equation. Mark your reference points with arrows, and show your math. x i = x f = d = Formula: Plug: Solve: x i = x f = d = Formula: Plug: Solve: x i = x f = d = Formula: Plug: Solve:

5 Air Trolley Lab Part I. Observe and Record Air Trolley Graph Data a. wind the air trolley propeller times b. complete five trials, and record the results Air Trolley Data Tria l Distance (cm) Part II. Calculate the Average a. add up the total distance b. divide by the total number of trials c. show work average d = Part III. Use class data to graph Air Trolley Data Title: Class Data Group Winds d (cm) check your graph! title label x axis label y axis include units label independent variable label dependent variable

6 Air Trolley Lab Questions?? Directions: Use the graph from our air trolley lab to answer the following questions 1. What is the relationship between the number of winds and the distance the air trolley traveled? as the number of winds increased, the distance 2. About how far will an air trolley travel with 53 winds? 15 winds? 65 winds? 37 winds? 3. How many winds will the trolley need to travel 150cm? 325cm? 700cm? 450cm? 4. What is the independent variable on this graph? 5. What is the dependent variable on this graph? 6. Why did we use a best-fit line on our graph?

7 Graphing Practice # 1 Mr. Backhaus science class was experimenting with an air trolley. They wanted to find out if the weight of the trolley affected the distance the trolley flew. They used a rubber band and put 70 winds on the propeller each time. They made a table with the data they gathered. Graph the results! weight (kg) distance (cm) check your graph! title label x axis label y axis include units label independent variable label dependent variable 1. What is the independent variable? 2. What is the dependent variable? 3. As the amount of weight increases, the distance.

8 Graphing Practice # 2 Mr. O Donnell s classes were experimenting with cockroaches. They wanted to know if the light affected the activity of the cockroaches. The students recorded how far each cockroach moved under different amounts of light. Below are their results. Use their results to make a graph and answer the following questions. # of lightbulb s distance (cm) check your graph! title label x axis label y axis include units label independent variable label dependent variable 1. What is the independent variable? 2. What is the dependent variable? 3. What is the pattern between the # of lights and the distance the cockroach traveled? As the number of lights used increases, the distance. 4. About how far would the cockroach travel if 5 light bulbs were used?

9 Graphing Practice # 3 The amount of sleep you get the night before a test might have an affect on how well you do on that test. The data below shows the results of an experiment where people were allowed different hours of sleep before taking a standardized test. Use the results to make a graph and answer the following questions. amount of sleep (hrs) test score % check your graph! title label x axis label y axis include units label independent variable label dependent variable 1. What is the independent variable? 2. What is the dependent variable? 3. What is the pattern between the amount of sleep and the distance the test score? As the number of hours increases, the distance. 4. About how many hours sleep would a student need to score and 80% on the test?
