Humans affect our planet a lot, in both good and bad ways. We breathe in oxygen and breathe out carbon dioxide. Plants need the carbon dioxide we exhale, so humans and animals are helping plants live. However, we also pollute our planet. Forests are being cut down, and plants and animals alike are running out of habitats because of humans. Also, trash in places where animals live can harm the environment. You may think it's perfectly harmless but to some deer out there, it won't be. It's not natural for animals to be eating tin cans and plastic bags.

For my QUEST project I studied stars. Most people know that our sun is a medium sized star, but that's pretty hard to imagine. I found this cool video on star size comparison that really gets the point across.

This shirt is made of 100% cotton. Cotton is a plant, so it is a renewable resource. .

This cup is made of glass. Since glass is made of sand which is made from weathered and eroded rocks which are usually non-renewable resources, glass is best classified as a non-renewable resource.

This paper towel roll is made of paper. Paper comes from trees. Since trees are plants which are renewable resources, paper towels are most likely renewable resources.

Season: The seasons are caused by the tilt of the Earth on its axis and its revolution around the sun. When the Northern Hemisphere is facing toward the sun, it is summer there. When it is facing away from the sun, it is winter. Sediment: Sediments are bits of rocks, shells, and plant and animal remains. Sediments can be compressed to form sedimentary rock.

Atmosphere: The atmosphere is a group of gases that surround the Earth. The air we breathe is from the atmosphere. The atmosphere also protects us from dangerous sun rays.

Fossil: A fossil is evidence of life in the past. Fossils can be bones, teeth, footprints, or plants.

Sedimentary rock: Sedimentary rock is rock that is formed when sediments are compressed together.

Adaptation: Adaptation is when an animal adapts, or changes to fit into, its environment. (ex) Some butterflies have adapted to their environment by changing color over time to hide from predators.

Photosynthesis: Photosynthesis is the process in which plants make food for themselves using water, carbon dioxide, and sunlight. Consumers: A consumer is somebody who uses or eats products, goods, or services. Producers: A producer is somebody that makes something. (ex) A farmer is a producer because farmers harvest crops for other organizms.

Omnivore: An omnivore is an animal that eats meat AND plants as a main source of food. (ex) Some bears are omnivores because they eat meat such as fish and plants such as berries.



Mixture: A mixture is two or more items evenly mixed together that can be easily seperated. (ex) Some apple slices, banana slices, and orange slices mixed together make a mixture.

Solution: A solution is two or more items evenly mixed together that either cannot be seperated or is not easy to seperate. (ex) Sugar dissolved in water creates a solution because it is not easily seperated, you have to evaporate the water.

Moon phase: A moon phase is the 'shape' of the moon as we see it from Earth. This depends on the moon's orbit around the Earth and the rotation of Earth on its axis. (ex) The full moon is when the moon looks like a full circle. A new moon is when the moon is not visible.

Gravity: Gravity is the force that keeps us on the ground. It pulls us toward the center of the Earth, so we dont fly sideways or up because of gravity, but we are forced down. (ex) If you drop a computer out of a window on Earth, it will fall down to the ground. If you drop one in space, it will just float around. This is because Earth has gravity, space alone doesn't.

Matter: Matter is anything that has mass, or takes up space. The 3 states of matter are solid, liquid, and gas. (ex) A rock is a solid. Water is a liquid. Oxygen is a gas.



Precipitation: Precipitation is when the water vapor in the cloud fall to the earth as rain, snow, and sleet.

Condensation: Condensation is when water vapor in the air forms together to create clouds. These clouds grow heavier and heavier and eventually let out all of the water, creating rain, snow, and sleet.

Evaporation: Water evaporates when the molecules in the water heat up. The molecules move faster and faster until they become a gas called water vapor.

Accumulation: Water accumulates when rain, snow, or sleet falls into a lake, river, or ocean. The water collects in these areas.

Weathering: Weathering is the process of breaking things down. Moving water, wind, plants, and ice can weather rocks. Water can carry away little sediments, wind can batter rocks and shells, cracking pieces off, plants can dig their roots into rocks and break them apart, and when water freezes, it expands creating cracks in the rock.
