Learn what an isotope is in chemistry. Isotopes are two or more types of atoms that have the same atomic number, which represents the number of protons and position in the periodic table but have different mass numbers due to different numbers of neutrons in their nuclei
In order to find the number of neutrons subtract the number of protons from the mass number.

Bill Gates has a net worth of around 93,000,000,000 dollars.
This is a large number to write.
A nanometer is 1/ billionth of a meter which is written as 0.000000001 m

Both of these numbers can be written using scientific notation.
Bill Gates net worth could be written as 9.3 x 10^10
A nanometer can be written as 1.0 x 10^-9
Lets go over the basics of scientific notation

9.3 x 10^8
The coefficient must be between 1 and 10
The exponent should be an integer and can be positive of negative

If you have to move the decimal to the left , the exponent will be positive
If you have to move the decimal to the right the exponent will be negative

530,000 5.3×10^5
First example. In this example we do not have a decimal so you can assume it is after the last zero. The coefficient must be between 1 and 10 so we need to move the decimal five places to the left because 5.3 is between 1 and 10
The exponent will be positive so it will be written as 5.3 x 10 5

.00078 x 10^-4

In this example in order for the coefficient to be between 1 and 10 we need to move the decimal four places to the right 7.8 is between 1 and 10
We need to move the decimal to the right so the exponent will be negative

The scientific notation will equal 7.8 x 10^ -4

Lichen is a combination of algae and fungi. It is estimated that 6% of the land on Earth is covered with lichen. This organism is a combination of algae or cyanobacteria living among fungi.
This mutualistic relationship allows the lichen to live in areas that would be impossible for plants.

In diesem Video erfährst du, warum es so viele unterschiedliche Apps gibt und welche du verwenden solltest. Darüber hinaus gibt es einen Überblick über die Geogebra-Suite und Vorschläge, welche Grundeinstellungen man generell vornehmen kann :)

Learn the difference between independent and dependent variables in research.
The independent variable can stand alone and is the variable that is being changed or manipulated.
The dependent variable is the variable that is being measured.
Learning the difference between these two types of variables can be very helpful in Science and any type of experiment.
I also cover how to graph these two types of variables.
