GED Science Practice Test

This GED® science practice test has questions and answers similar to those that could be asked during your official GED® tests. In this practice test you’ll find questions on physics, chemistry, scientific method, and more.

Results

#1. Physics: What are the states of matter?

#2. Evolution: What is an example of evolution?

#3. Earth/Space: Earth’s seasons are caused by:

#4. Science Experiment/variables in an experiment: An experiment for a new drug used mice to test its effectiveness. Group 1 consisting of 12 mice were given an injection of 1 mg of the new drug. Group 2 consisting of 12 mice were given an injection of a placebo. Group 3 consisting of 12 mice were not given any injection. Which of the following is the control group in the experiment?

#5. Science graph/image interpretation: Which of the following does this image represent?

#6. Science reading section interpretation: What is Eutrophication? It’s a problem that should matter to you, whether you live near the ocean or not. That’s because it begins wherever people live and ends with damage to resources we all use and enjoy.It all starts when nutrients get into lakes and oceans. Remember, what’s waste to humans can be food to plants and other creatures. Nutrients feed algae, like they do other plants. Algae grows and blocks sunlight. Plants die without sunlight. Eventually, the algae dies too. Bacteria digest the dead plants, using up remaining oxygen, and giving off carbon dioxide. If they can’t swim away, fish and other wildlife become unhealthy, or die without oxygen. But it doesn’t have to be this way. Protecting marine resources starts with sound agricultural and waste management practices. What is the cause of eutrophication?

#7. Genetics: Brown eye color is a dominant trait, while blue and green eye colors are a recessive trait. Which of the following terms describes how there can be more than one type of eye color in humans?
