Carl Linnaeus classified all living things into groups based upon their physical features. His system placed organisms with the most similar characteristics together in a group he called the “species”.
A species is defined as all organisms that are able to breed with one another, and most importantly, are able to produce fertile offspring.
The species group is accepted as the smallest unit of biological classification and is always given a Greek or Latin name.
The emergence of a new species from an existing one happens as a result of natural selection. This process is called speciation. Some scientists believe that speciation occurs continuously over long periods of time, whilst others believe that speciation occurs only rarely, and in relatively short bursts, sometimes as a result of a dramatic environmental event.

A Handful of Singular Species
Animation project I did for class. There are definitely some technical issues, but I’m proud of my accomplishments! I wrote the poem too.
Learn Singular Plural in English Grammer for Grade 1 2 3 | Noun Number list with Pictures and Rules
Most singular nouns are made plural by simply putting an s at the end. There are many different rules regarding pluralization depending on what letter a noun ends in. Irregular nouns do not follow plural noun rules, so they must be memorized or looked up in the dictionary.
Plural Noun Rules
There are many plural noun rules, and because we use nouns so frequently when writing, it’s important to know all of them! The correct spelling of plurals usually depends on what letter the singular noun ends in.
1 To make regular nouns plural, add ‑s to the end.
cat – cats
house – houses
2 If the singular noun ends in ‑s, ss, sh, ch, x, or z, add ‑es to the end to make it plural.
Bus Buses
Dress Dresses
Bush Bushes
Bench Benches
Box Boxes
Blitz Blitzes
3) If the noun ends with ‑f or ‑fe, the f is often changed to ‑ve before adding the s to form the plural version.
wife – wives
wolf – wolves
Exceptions:
roof – roofs
belief – beliefs
chef – chefs
chief – chiefs
5 If a singular noun ends in ‑y and the letter before the y is a consonant, change the ending to ‑ies to make the noun plural.
city – cities
puppy – puppies
6 If the singular noun ends in y and the letter before the y is a vowel, simply add an s to make it plural.
ray – rays
boy – boys
7 If the singular noun ends in ‑o, add ‑es to make it plural.
potato – potatoes
tomato – tomatoes
Exceptions:
photo – photos
piano – pianos
halo – halos
With the unique word volcano, you can apply the standard pluralization for words that end in o or not. It’s your choice! Both of the following are correct:
volcanoes
volcanos
8) Some nouns don’t change at all when they’re pluralized.
sheep – sheep
series – series
species – species
deer –deer
Plural Noun Rules for Irregular Nouns
Irregular nouns follow no specific rules, so it’s best to memorize these or look up the proper pluralization in the dictionary.
child – children
goose – geese
man – men
woman – women
tooth – teeth
foot – feet
mouse – mice
person – people

Classification
Explores classification in biology as well as taxonomy hierarchy: domain, kingdom, phylum, class, order, family, genus, and species with The Amoeba Sisters! This video also discusses the importance of scientific names and why classification can have major changes due to DNA and cell structure evidence. Video has a handout: http://www.amoebasisters.com/handouts.html. See table of contents by expanding details 👇
Table of Contents:
Intro 00:00
Importance of DNA in naming 1:04

Domains 2:04
Kingdoms 3:51
Phylum, Class, Order, Family, Genus 5:52
Species and Scientific Name 6:06
Common Name vs Scientific Name 6:49
Important Vocabulary:
Prokaryotes vs. Eukaryotes
Autotrophs vs. Heterotrophs
Unicellular vs. Multicellular
Cell Wall vs No Cell Wall (All cells have a membrane!)
Binomial Nomenclature
P.S. When we went back through subtitles, we realized we have a mispronunciation. Oh Archaea. We’ve heard arKEEə. We’ve heard arKAYə. But there’s a mispronunciation here for that domain just to let you know.
The Amoeba Sisters videos demystify science with humor and relevance. The videos center on Pinky’s certification and experience in teaching biology at the high school level. For more information about The Amoeba Sisters, visit:
