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. Know that gravity does work on water: objects like rocks that cannot float are immediately pulled to the bottom. And gravity does work on birds (and planes, and other things that fly) - it's just that birds have the ability to work against gravity's pull by flapping their wings. But if they stop using their wings, gravity will pull them to the ground.

Gravity is a force that pulls objects downward, so when you jump up in the air you'll always come back down. Gravity doesn't mean that nothing can ever go up: trees can grow up into the sky, sand can blow into the air - but gravity keeps them from floating away.

The fact that it is hard work to run or walk uphill but much easier to run downhill shows how gravity pulls things downward. If you are going downhill, gravity is working with you to help you get there, but if you're going uphill you have to work against gravity. Note that the heights of trees isn't really constrained by gravity but instead by the kind of tree, the nutrients it receives, and those things. The fact that big planes can fly also isn't good evidence for gravity; planes use advanced technology to counteract the force of gravity, or otherwise they'd be pulled down. And although the stars in the sky are affected by gravity in their own way, they're not good examples of how things are pulled downward by gravity since to us from our vantage point they're way up in the sky.

Because gravity pulls things down toward the ground, dropping objects to show how quickly they fall would be a good way to demonstrate how gravity works.

A slide is fun because of the way that gravity pulls you down once you get started sliding. You don't have to do any work - once you let go, gravity does the rest! The other equipment requires you to climb or push; slides use gravity to give you all the fun without the work.

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 Monica because she is moving more matter (tiny particles) into a balloon and even though we cannot see them, we can see how the balloon gets larger. Deontay is correct that he could keep breaking things apart, but he has a hypothesis and is not conducting an experiment or a demonstration. Celeste's project is about photosynthesis.

The answer is none of these because the description mixes several key features of solids, liquids, and gases.

Atoms 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.

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. We cannot see atoms with the naked eye. Trillions of atoms could fit inside the dot on top of the letter "i." The radius of an atom is less than one nanometer or a billionth of a meter.

Electrons have a negative charge. The proton moves around the nucleus of an atom, which is in the center. The charge of an electron is opposite but equal to the charge of a proton. Atoms have the same number of electrons as protons. We cannot see these with our eyes, and even with a high-powered microscope, they are too tiny and too low in mass to see.

Atomic theory is the name of the theory described in the question. Atoms are very tiny and cannot be seen without a microscope. They are made up of parts that determine what the atom is, how it acts, and its mass. Inside of atoms are protons, neutrons, and electrons.
