Science Skills
This type of variable is the one that is changed during an experiment.
What is the independent variable?
This kingdom includes organisms like kangaroos and humans.
What is the Animalia kingdom?
This type of organism is always at the bottom of a food chain.
What is a producer (or plant)?
This process in the water cycle turns water vapor into liquid.
What is condensation?
This phase of the Moon occurs when the Earth is between the Sun and the Moon.
What is a full moon?
This method is used to separate a soluble solid from a solvent.
What is evaporation?
This is the process of changing from a liquid to a gas.
What is evaporation
This tool is used to separate a solid from a liquid in a laboratory.
What is filter paper (or a filter)?
This type of adaptation allows an organism to modify its behavior, like the red kangaroo licking its paws to cool down.
What is a behavioral adaptation?
This term describes an animal that only eats plants.
What is a herbivore?
This term describes the movement of water from plant leaves to the atmosphere.
What is transpiration?
This model, proposed by Copernicus, describes the Sun at the center of the solar system.
What is the heliocentric model?
This piece of equipment is used to separate a mixture by spinning it very fast.
What is a centrifuge?
This state of matter has no fixed shape and no fixed volume.
What is a gas?
This step in an experiment involves stating the outcome based on the evidence gathered.
What is the conclusion?
This type of key is used to classify organisms based on their physical characteristics.
What is a dichotomous key?
This animal is at the top of the food chain and has no natural predators.
In the water cycle, this process involves water turning from liquid to vapor due to heat.
What is evaporation?
The Earth takes this amount of time to rotate once around its own axis.
What is 24 hours?
This technique is used to separate liquids with different boiling points, such as separating alcohol from water.
What is distillation?
This process occurs when a gas changes directly into a solid.
What is deposition?
This is an important piece of safety equipment used to protect a scientist's feet.
What are enclosed leather shoes?
This type of adaptation allows an organism to survive in extreme environments, such as the ability of certain bacteria to thrive in volcanic hot springs.
What is a physiological adaptation?
This process allows plants to make their own food and is essential for most food chains.
What is photosynthesis?
This part of the water cycle is responsible for the formation of clouds.
What is condensation?
This occurs when the Moon passes directly between the Earth and the Sun.
What is a solar eclipse?
This technique is used to separate an insoluble solid from a liquid by pouring off the liquid without disturbing the solid.
What is decantation?
This state of matter is the least dense, with particles far apart.
What is a gas?
