If the sunflower continues growing at the same rate for another month, what will its final height be?
Lisa is growing different types of plants in a greenhouse. She records how much each plant grows over one month. However, some data is missing.
Data Table: Plant Growth Over One Month
Plant Type | Starting Height (cm) | Final Height (cm) | Growth (cm) |
Sunflower | 20 | 50 | |
Tomato | 15 | 18 | |
Pea | 10 | 35 |
Which plant had the most growth?
Ethan is experimenting to see how water boils at different temperatures. However, he forgot to record some of his data.
Data Table: Starting Water Temperature and Boiling Time
Starting Temperature (°C) | Time to Boil (minutes) |
0 | |
20 | 10 |
40 | 8 |
60 | |
80 | 4 |
Complete the missing values by identifying the pattern
How does starting temperature affect boiling time?
If the pattern continues, how long would it take for water starting at 90°C to reach boiling? Show your reasoning.
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 |
According to the results, which ramp height resulted in the largest distance traveled by the toy cars?
Based on the data, how far do you estimate a toy car might travel if the ramp height were 25 cm?
Use data from the table to explain your estimate.
