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?
If the sunflower continues growing at the same rate for another month, what will its final height be?
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.
