5th Grade Review

Experimental Design

100

This is the statement or prediction a scientist makes before an experiment.

Hypothesis

200

This is the factor, condition, or event in an experiment that a scientist purposely changes on test groups.

Independent variable

300

This is the part of an experiment that is kept under normal conditions and used as a benchmark to compare results.

Control group

400

To keep a science experiment fair, a scientist must only change this many independent variables at a single time.

One.

500

These are the factors in an experiment that must be kept exactly the same across all testing groups to prevent them from affecting the results.

Controlled variables

Observations vs. Inferences

100

Scientists gather this type of information directly by using their five senses or specific tools like rulers and balances.

Observation.

200

This is an explanation, conclusion, or guess about an event based on your prior knowledge and observations, rather than direct sight

Inference

300

"The classroom walls are painted light blue." This statement is an example of this specific type of data. 

Observation

400

"The sidewalk is completely wet, so it must have rained outside a few minutes ago." This statement is an example of this scientific thinking process.

Inference

500

This type of observation relies strictly on numerical data, measurements, or counting, rather than descriptions or colors.

Quantitative observation

Investigations vs. Experiment

100

Unlike a general investigation, this specific type of study requires a controlled test with manipulated variables.

Experiment.

200

An astronomer mapping out constellations or a geologist tracking rocks in a local state park is doing this type of scientific work instead of a controlled lab experiment.

observation

300

This type of scientific investigation uses an object, a computer program, or a diagram to represent things that are too large, small, or dangerous to test in real life.

Model

400

This data-collection method involves handing out questionnaires to a large group of people to collect and analyze their responses.

Survey

500

This is the primary reason why a controlled laboratory experiment cannot be conducted to figure out how dinosaurs behaved millions of years ago.

We cannot control variables in the past.

Replication & Repitition

100

This is what a single scientist does when they conduct multiple trials of their own experiment back-to-back.

Repitition

200

This is what occurs when an entirely different scientist reads a published report and performs the exact same experiment to see if they get the same data.

Replication

300

Scientists do this to their trials to make sure their results are reliable, accurate, and not just a one-time accident.

Repeating trials

400

To allow other scientists to replicate their work perfectly, a researcher must write down a very clear, step-by-step list of these.

Procedures

500

When two different groups of scientists get completely different results from the exact same experiment, this is what they must do next to resolve the difference.
