Physical Science - 5th Grade Science

The answer is a staple, because a staple has all of the properties listed. An ice cube does not exist as a solid at room temperature. A wagon is not 1 cm long and cannot be bent with your hand. A pair of scissors is also not a centimeter long.

Water vapor is a gas, and you may have heard the term when discussing the water cycle or evaporation. When thinking about the three states of matter that can describe a substance, it can be either a solid, liquid, or gas. These can be hot or cold by definition, colorless, light or heavy, but only one ca spread through their air with no definite shape; that is a gas. A gas has no shape and would spread throughout the air; if it is trapped in a container, it will continue to move about the container and not remain stationary.

Plants' nutritional energy comes from the Sun. Plants use chlorophyll to photosynthesize the Sun's energy into plant energy. Through the photosynthesis process, producers, such as grass, absorb the Sun's light energy to produce food (stored sugar and starches). Photosynthesis is how plants convert the Sun's energy into their energy.

The energy in the meadow starts with the Sun. The Sun then provides energy to the grass through the process of photosynthesis. The rabbit eats the grass, and the rabbit absorbs its energy. Finally, the snake eats the rabbit, and it absorbs the rabbit's energy. Energy travels from the Sun and moves through the ecosystem with each consumer along the chain.

The Law of Conservation of Matter says that the amount of matter stays the same, even when matter changes form. Sometimes it may seem that matter disappears during a science experiment, but this law tells us that matter cannot magically appear or disappear, it simply changes from one form to another.

The answer is baking soda. Baking soda is a common household product that is a base. Vinegar is an acid. Acids and bases react chemically when combined.

The answer is "it can be used to make other things." This is not a property of matter. Some common properties of matter are: color, luster (how shiny it is), texture, inertia, mass, weight, volume, density and specific gravity.

The answer is "all of these." This is not a property of matter. Some common properties of matter are: color, luster (how shiny it is), texture, inertia, mass, weight, volume, density and specific gravity.

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.

The answer is liquid number 2. Density is a measure of the amount of "stuff" in a given volume. More dense objects sink and less dense objects float.

The answer is 45 because there are 10 millimeters in a centimeter and the ruler is measuring 4.5 centimeters.

A physical change is a change is a substance that does not change what the substance is. In contrast, in chemical change a new substance is formed.

Let's look at our options:

When wood is burned, the wood turns into ash. We can't get the piece of wood back once it's been burned; thus, wood burning is a chemical change.

When a cake is baked, the ingredients combine and turn into a cake once it's baked. Once we have a cake, we can't get the ingredients back; thus, baking a cake is a chemical change.

When a nail rusts, pieces of the metal nail have turned into rust. We can't get the original nail back; thus, a nail rusting is a chemical change.

Ice is made up of water, and when the ice melts we are left with a puddle of water. If we freeze the water, it will turn back into ice; thus, melting ice is a physical change.

Cutting a piece of wood does not change the wood, it's still a piece of wood, just smaller; thus, cutting a piece of wood is a physical change.

Butter melting is similar to ice melting. When butter melts, it can be frozen back to butter; thus, butter melting is a physical change.

When wood is burned, the wood turns into ash. We can't get the piece of wood back once it's been burned; thus, wood burning is a chemical change.

The answer is "at number 3" because you measure volume at the meniscus.
