Which computer has the cheapest extragigabyte of Random Access Memory(RAM)?2. If you wanted to buy a computerwithout extra RAM or hard drive space,which computer is the best to buy?3. Which computer is the most expensive if you buy it with all the extra options?4. Which computer is the best deal if you really need extra RAM but not extra drive space?5.

Amanda made this entry in her laboratory notebook: “We are doing an experiment to determine if thesize of soil particles affects the amount of water that flows through soil. We poured 100 milliliters (mL) ofwater through four different types of soil. The equipment is shown below.We got the following results: With gray soil, the average particle size was 2.0 millimeters (mm) and 80 mLof water flowed through. We then used tan soil. Its average particle size was 0.5 mm and 40 mL of waterflowed through. With brown soil, 60 mL of water flowed through. Brown soil has an average particle sizeof 1.5 mm. In our last trial we used black soil. It has an average particle size of 1.0 mm and 50 mL ofwater flowed through.”a Using the data table below, organize the results to show the average particle size and the amount of waterthat flowed through for each type of soil. Be sure to include column headings, data, and units in the table.[6 points]b What is the dependent variable in this experiment? [2 points].c What conclusion can be drawn from the data that the students collected? [4 points]Assessment Practice/612

Work Hard, Get Smart.Scientific Method Packet 3ChallengeA group of students were trying to figure out if the temperature of the water affected the speed of acrawfish. They set up 8 tanks of water and kept them at different temperatures. They then placedcrawfish in each tank and made them swim and measured their speed. Using the data at the left,construct a graph that shows the relationship between water temperature and crawfish speed.Don’t forget to:1) Create a title2) Label your axes3) Make an appropriate scale4) Mark an X at each data point and connect them with a 302.5352.5401.9451.5501.2Tables to Graphs/1718

The Effect of Temperature on the Amount of Sugar that Dissolves in TeaNote About How to Make the Best Scale.Almost always start at zero.Scales always increase by the same amount.One way to do it is to see the highest and lowest value of a group. If there is a large difference forexample 0 to 100. Then you might want to count by a large number like 10. If it is 1 to 10 then youmight want to count by 1s.What ever you do make sure you are always increasing by the same amount. For example:(0, 2, 4, 6, 8, 10)(0, 0.5, 1.0. 1.5, 2.0, 2.5)(0, 5, 10, 15, 20, 25)19
