The atmosphere protects us from bad heat from the sun, and makes air pressure.

Heat can be transferred from one place to another by three methods: conduction in solids, convection of fluids (liquids or gases), and radiation through anything that will allow radiation to pass. The method used to transfer heat is usually the one that is the most efficient.

Biotic factors are parts in an ecosystem that are living. Abiotic factors are the factors that aren't living. An organism is one singular living thing. A community is more than one of the same organism. Population is a population in an area. And symbiosis are mutalism, commensalism, and parasitism.

All matter can be classified into two categories: pure substances and mixtures. A pure substance consists of a single element or compound. Iron is formed only of iron (Fe) atoms; table salt is formed only by sodium chloride (NaCl) molecules. A mixture, however, is made up of different compounds and/or elements.

A physical change is when something changes in a physical way, like a ice cube turns into water. A chemical change is when something changes the whole object, like wood turning into a fire which turns into ash.

Metamorphic rock is magma dried up and made into a rock.

Sedimentary rock is made when sediment keeps stacking up, and up, and up, until it makes a rock.

Igneous rock is made when magma makes a volcanic eruption and the lava that dries up makes it igneous rock.

There are differences for animal and plant cells. But, there are things in common, like all cells have a cell wall, vacuoles, a nucleus, mitochondria, etc.

On the periodic table, there are all the elements organized on a table. They are abbreviated, with the atomic numbers, and how much it weighs.

In the nucleus or the middle of the atom, is filled with protons which are positive and neutrons. And if there are 9 protons, the atomic number is 9. In a cloud around the nucleus there are electrons which are negative.

Primary succession is when moss and lichen breaks down rocks and makes soil. Secondary succession is when something like a flood or a fire happens and then over hundreds of years the place becomes filled with nature again.

There are 7 steps to the Scientific Method. 1. Observation or Question 2. Research 3. Hypothesis 4. Experiment 5. Collect Data 6. Analysis 7. Conclusion
We use it to help us solve problems. We use it by using steps.
