A scientist was studying a rabbit population in a grassland ecosystem. They wanted to determine whether the number of rabbits increased, decreased, or remained stable over time. Every month for six months, the scientist counted the number of rabbits in a specific area. They expected the population to grow steadily, but environmental factors such as food availability and predators could influence the results.
Month | Rabbit Population |
|---|---|
January | 12 |
February | 18 |
March | 24 |
April | 30 |
May | 26 |
June | 22 |
What scientific question was the scientist trying to answer?
A student wanted to investigate how different amounts of baking soda affect a reaction with vinegar. They set up an experiment where they kept the amount of vinegar the same in every trial but increased the amount of baking soda. The student measured the height of the bubbles produced in each reaction to see if adding more baking soda led to a bigger reaction.
Trial | Amount of Baking Soda (g) | Amount of Vinegar (mL) | Bubble Height (cm) |
|---|---|---|---|
1 | 5 | 20 | 10 |
2 | 10 | 20 | 18 |
3 | 15 | 20 | 25 |
4 | 20 | 20 | 30 |
What was the scientific question the student was investigating?
A scientist wanted to determine which type of soil holds the most water. They tested three different soil types: sand, clay, and loam. They poured the same amount of water into each soil type and measured how much water drained out after 10 minutes. The scientist expected that some soils would retain more water than others, affecting plant growth in different environments.
Soil Type | Water Added (mL) | Water Drained (mL) | Water Retained (mL) |
|---|---|---|---|
Sand | 100 | 85 | 15 |
Loam | 100 | 50 | 50 |
Clay | 100 | 30 | 70 |
