Fun Writing In Scientific Notation Worksheet For Kids (100% FREE)
What is Scientific Notation? Have you ever calculated the distance from the sun to the earth? Of course for those of us who are still confused about calculating the distance. Usually to calculate the distance of an object to another object we use a formula. Often the formula is very complicated, so many are still confused about using the formula for calculating distance.
In the lesson, we learned how to easily calculate distances using scientific notation. This is a procedure for writing numbers that accommodates very large or very small values to facilitate notation writing in standard decimal notation. Scientific notation has a number of useful properties and is commonly used in calculators and by scientists, mathematicians, doctors, and engineers.
There are three parts to writing numbers in scientific notes, namely the coefficient that shows any real number between 1-10, the base is the decimal number 10, and the third is the exponent which is the power to which the base is raised. In this worksheet every number 1 to 10, if multiplied by the exponent, the result is the exponent or exponent.
For example, the number 125, if written in standard form becomes 1.2 x 102. Writing a number greater than or equal to 10. If the number in scientific notation sheets that is more than 10 does not have a comma (not a decimal) then make a comma after the number rear. Besides, use positive powers if the decimal point is shifted to the left. For example, 27,000,000 = 2.7 x 107.
Writing with Scientific Notation
To write the measurement results into scientific notation is quite easy. You just need to see if the number is more than 10 or less than 1. Writing in the Scientific Notation sheet for Numbers more than 10, how:
If a number greater than 10 does not have a comma (not a decimal), make a comma after the last digit. If the number already has a comma, you don’t need to add it again.
- Make a comma to the right of the first digit.
- Eliminate any leading zeros other than those between non-zeros
- Multiply the number you can in the number 3 by 10n, where n = the number of numbers enclosed in two commas. 120,000,000,000,000 (the number we will represent in scientific notation).
Scientific Notation for Numbers Less than 1, how:
- Make a comma behind the first non-zero number that you meet from the left
- Eliminate the number behind the first number you meet (step 1)
- Multiply the number 2 by 10-n by n = the number of digits enclosed in commas.
0.00001276 and 0.00001.276 (make a comma after the first nonzero number found from the left). 1,276 x 10-5
Writing Scientific Notation for Large Numbers
The large number in question is more than 10. The method of writing scientific notation for numbers more than 10 is as follows:
- Pay attention to the numbers listed.
- Take the number from the front until before the zero.
Example of the number 149,600,000 which is the distance from Earth to the Sun.
The number from before zero is 1.496.
- Put a comma in the numbers you separated so that the value is not more than and not less than 1.
For example, from the number 1.496, the comma must be placed behind the number 1 to become 1.496.
- If you put a comma after number 4 the value becomes 14.96 (more than 10).
1.496 is the value of a
- Determine the exponent or exponential number by counting the number of zeros that have been omitted and the decimal places.
For example, if 149,600,000 becomes 1,496 zeros, there are 5 omissions.
- Then, at the number 1,496 behind the comma, there are 3 numbers, namely 4, 9, and 6.
So, the value for n or the exponent or exponent is 5 + 3 = 8
Eight is the value of n with a positive value to signify scientific notation greater than 10.
Write down the scientific notation that you have defined.
For example, 149,600,000 = 1,496 x 108
Those are some ways to write scientific notation on scientific notation sheets very easily and practically.
