This is the first of our free GED Science practice tests. The new 2014 GED Science test has challenging questions that will require you to read complex scientific texts, evaluate charts and graphs, and use evidence to make inferences. To prepare for this you will want to work through as many practice questions as possible. These online practice questions include answers and detailed explanations. Start your test prep now with our GED Science practice test.

Based on the passage above, if genetically modified crops were to be banned, what could be the largest negative impact to humans?
Introduction of new allergens into the food supply
Loss of genetic diversity in food crops
Decreases in food production worldwide
Increase in the amount of beneficial insects
It could be argued that this experiment was not set up using proper experimental protocol. What would need to change in the experiment for the results to be valid?
The batteries should have all been either name brand or generic
Only two groups should have been tested at a time
The same battery should have been used in each flashlight
The same flashlight should have been used to test each battery
When 6 molecules of carbon dioxide are used, 1 molecule of oxygen is produced
When 1 molecule of water is used, 1 molecule of glucose is produced
When 6 molecules of water are used, 1 molecule of glucose is produced
When 1 molecule of glucose is produced, 12 molecules of oxygen are used
If you were reading a scientific report, and it referred to a wavelength of 455 nm, which color would it be referring to?
20, 15, 12, 17, 15, 19, 9
Then put them in order:
9, 12, 15, 15, 17, 19, 20
There are 7 numbers total, which means that the 4th number is the one in the middle. The 4th number is 15, so 15 is the median.
20 − 9 = 11
Which of the following organisms fill more than one role in this ecosystem?
If additional cheetahs were introduced into this ecosystem, shortly thereafter we would expect a decrease in the:
dung-rolling beetle population
1025 + 175 = 1200 mL
To convert milliliters to liters, divide by 1000:
1200 ÷ 1000 = 1.2 L
