This is the first of our four GED Science practice tests. The 2023 GED Science test includes 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. Get started with your test prep right now with this free 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
The square above is based on the eye color of two parents. One of the parents has brown eyes and carries the recessive gene for green eyes (a). What is the probability that a biological child of these parents will have brown eyes?
Below is the chemical equation for photosynthesis:
Which of the following statements about photosynthesis is correct?
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?
What is the median of number of hurricanes per decade?
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.
What is the mode of this data set?
What is the range of this data set?
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
As part of a chemistry experiment, 1025 milliliters of water is mixed into a beaker that contains 175 milliliters of motor oil.(1 liter = 1000 milliliters)
After adding the water, how many liters of liquid are in the beaker?
1025 + 175 = 1200 mL
To convert milliliters to liters, divide by 1000:
1200 ÷ 1000 = 1.2 L
