Gravity on earth pulls objects downward toward the ground. Rain is a good example: the clouds don’t “throw” the rain to the ground, but instead, when there is so much water that it gets heavy for the cloud to hold, the water then falls to the ground because of gravity. In this example, the roots will grow downwards because of gravity. Geotropism is the influence of gravity on plant growth or movement. “Geo” means earth or ground, and “tropism” means a plant movement triggered by a stimulus. In this case, the stimulus is gravity. Roots explore the soil looking for water and nutrients to absorb.

The statement, "Gravity can act between objects that are not touching," is correct. Gravity exerts a pull on other objects, and this can take place between objects that are not touching. Gravity can act over long distances (like between objects in the solar system). On Earth, we feel gravity when we are going down a slide or rollercoaster, riding a bike downhill, or letting a toy cr go from the top of a ramp. There is an invisible dove that pulls everything downwards, gravity.

Matter is anything that takes up space. Matter is in the form of solid, liquid, or gas. Solids, liquids, and gases are made of tiny particles called atoms and molecules. In a solid, the particles are very attracted to each other. They are close together and vibrate in position but don’t move past one another. In a liquid, the particles are attracted to each other but not as much as they are in a solid. The particles of a liquid are close together, always moving, and can slide past one another. In a gas, the particles have very little attraction to each other. They are very far apart compared to the particles in a solid or liquid, and are constantly moving. The particles don’t interact with one another but just hit and bounce off of each other when they collide.

The answer is a liquid. They are too close together to be a gas, but not in a specific formation like a solid.

The answer is none of these

A scientific model can be used a show scientists' understanding of an object, event, or process. Models can be used to generate new questions, used as a tool to support thinking, and models are tools that scientists can use to predict events.

Solids, liquids, and gases are made of tiny particles called atoms and molecules. Atoms and molecules are what make up all matter. They are the smallest particles of any element. They still have the same properties as the element they make up. An atom of aluminum still has the same melting point as an aluminum can. They are so tiny we cannot see their color, but if we zoomed in with a scanning tunneling microscope or electron microscope, we would see they would be the same color.
