Science
GED Science Practice Test 5
Forty new multiple-choice questions, none repeated from earlier tests. This set puts more weight on cell structures, how the body keeps itself in balance, heat and solutions, resources and human impact, and the flaws that weaken an experiment. Several items give you a formula and ask you to use it. After you finish, use the review method below to learn as much from your right answers as from your wrong ones.
Question 1 of 40
0 answered
A food safety class explains that bacteria cells have a cell membrane, ribosomes and DNA, but no nucleus. Human cheek cells have all of these plus a nucleus. Which statement best describes where the DNA is found in each type of cell?
Review in two passes
In the first pass, read the explanation for every question you missed. Write one line for each: what the question was really asking and which clue in the passage or table pointed to the answer. Most misses on GED Science come from reading the setup too fast, not from a missing fact.
In the second pass, go back to the questions you got right but were unsure about. A lucky guess hides a gap that can cost you on test day. If your reasoning did not match the explanation, treat that question as a miss and add it to your notes. Retake only the questions in your notes a few days later.
Questions that give you a formula
Some items here state a formula in the passage, such as heat equals mass times specific heat times temperature change, or kinetic energy equals one half times mass times speed squared. You do not need to memorize these. Write the formula, list each value from the passage next to its symbol, and only then calculate.
Watch for the step that wrong choices are built from. A question may give a starting and ending temperature when the formula needs the change, or a speed that must be squared. Before you pick an answer, check that the units match the choice and that the size of the number makes sense.
Frequently asked questions
- Should I time myself on Practice Test 5?
- Yes, if you want to test your pace. The real Science test allows 90 minutes, so take this set in one sitting and note any question that slowed you down.
- What should I do if I keep missing experiment design questions?
- Study the scientific practices page. For each experiment, name what was changed, what was measured, and what else changed by accident before you look at the choices.
