Based on the data, if you wanted to buy a new winter coat for a cold environment, which materials would be the best at keeping you warm? Why?
Support your answer with data from the table.
Armando wants to study how well various materials act as insulators. He puts 75°C water in four glasses in a 0°C room. He covers each glass with a different material and leaves for 60 minutes.
Data Table: Temperature Change of Water
Glass Covered with.. | Beginning Temperature of Water in Glass | Water Temperature After 60 Minutes |
Wool | 75°C | 60°C |
Fur | 75°C | 65°C |
Feathers | 75°C | 56°C |
Leather | 75°C | 49°C |
Based on the data shown, if the water were left for another 60 minutes, which glass of water would have the lowest temperature?
Allison is experimenting to see how different liquids cool.. However, she forgot to record some of his data.
Data Table: Cooling of Liquid V and Liquid X
Time | Liquid V Temperature (°C) | Liquid X Temperature (°C) |
1 | 47 | 90 |
2 | 41 | |
3 | 35 | 50 |
4 | 30 | |
5 | 23 | 10 |
Complete the missing values by identifying the pattern. Then, answer: What was the total temperature loss for liquid X?
When does liquid X become cooler than liquid V? Support your answer with evidence from the data table.
Three groups of students test how far a toy car would travel down ramps elevated to various heights, starting at 5cm. The results are below:
Data Table: Toy Car Distances on Ramps of Different Height
Ramp Height | Group 1 | Group 2 | Group 3 |
5 cm | 55 cm | 66 cm | 56 cm |
10 cm | 64 cm | 74 cm | 66 cm |
15 cm | 71 cm | 83 cm | 73 cm |
20 cm | 78 cm | 91 cm | 84 cm |
Which statement best describes the relationship between ramp height and the distance traveled by the toy car?
Two of the groups have similar data and one group has data that stands out. Which two groups have similar data? Which group stands out? What error could that group have made in their experiment?
