TRUE OR FALSE: Most water on Earth is salt water.
True - most water on Earth is in the ocean, which is salt water.
A force that pulls objects "downward" or towards the center of the mass.
Gravity
TRUE OR FALSE: Soil is needed for plants to grow and photosynthesis.
False. Photosynthesis only requires water, sunlight, and carbon dioxide.
*But!! Highly nutrient soil is a bonus*
TRUE OR FALSE: If the temperature of matter increases, that means the energy of the particles decrease.
FALSE - If temperature increase, then the energy decreases
*Note: Temperature is a measurement of energy of motion*
Plants use these 3 things to make sugar (or their food).
Water, sunlight, and carbon dioxide
The four spheres of Earth.
Hydrosphere (water and ice)
Biosphere (living things)
Geosphere (land, rocks, and soil)

If a scientist is performing a chemical experiment in a closed flask, and they see matter "disappear" in their flask. How does the mass change?
The mass does not change. The amount of mass in matter will be conserved even when a phase change takes place or a new substance is formed.
This happens because of decomposers in the ecosystem.
Biological matter is recycled back into the environment
Name a way humans can help with conservation and the World Water Crisis.
- Farmers can use more efficient agriculture water systems so they don't waste water
- Cities or farmers create systems to control runoff
- Stop polluting and pick up trash before it gets into the water
- Use less water so it is not wasted
1) Explain why the sun is brighter than the stars we see at night.
2) What happens to the other stars during the day time?
1) The sun is the closest star to us to it seems to be brighter than the other ones.
2) During the day, the sun makes our sky so bright than we can't see the light from the dimmer stars, BUT they are still there.
