1.

What does "observing over time" involve in a scientific investigation?

Recording changes to something at intervals over a period of time

Testing only one variable while controlling others

Sorting living things into groups

2.

Fill in the blank:

When observing over time, scientists often use a to record their observations at regular intervals.

3.

Observing the growth of a plant over several weeks is an example of observing over time.

True

False

4.

Fill in the blank:

Sorting living things into groups based on their shared features is called .

5.

What is a classification key used for?

To help identify an organism by asking a series of questions about its features

To measure the speed of a moving object

To record temperature changes over time

6.

Fill in the blank:

Living things can be divided into two main groups: vertebrates and .

7.

Pattern seeking investigations look for a relationship between two variables.

True

False

8.

Fill in the blank:

In pattern seeking, scientists often cannot all the variables, unlike in a fair test.

9.

Which is the best example of a pattern-seeking investigation?

Collecting data on shoe size and height from many people to see if they are related

Changing the amount of light a plant receives while keeping everything else the same

Sorting rocks into igneous, sedimentary and metamorphic groups

10.

Fill in the blank:

A good way to spot a pattern in data is to plot it on a .

11.

Classifying always involves changing a variable to see what effect it has.

True

False

12.

Fill in the blank:

Observations made regularly over weeks, months, or even years can reveal changes, such as the seasons.

13.

Why might a scientist study the same habitat, such as a pond, over an entire year?

To see how the plants and animals living there change with the seasons

To classify the pond into vertebrate and invertebrate groups

To carry out a single fair test on the water

14.

Fill in the blank:

When looking for patterns, scientists usually collect data from many or samples to compare.

15.

Identifying and classifying are exactly the same skill and cannot be told apart.

True

False
