Science Vocabulary Dissection: Root words and Morphemes By: Allison Bush

Learning Objectives Understand the function of root words, prefixes, and suffixes. Create new words by adding prefixes and suffixes to root words. Increase vocabulary understanding by applying prefix and suffix knowledge.

Let Us Form An Hypothesis! How can you identify a root word, prefix and suffix? Give an example. Write your response in your science journal. Pair and share your response with elbow partner(s).

Is Your Hypothesis Correct Is Your Hypothesis Correct? Review the following video snippet: Root Words, Prefixes and Suffixes

I DO Strategy A root is a word part that comes from another language, such as Greek or Latin. Affixes can be divided into two categories: prefixes (appear at the beginning of words) and suffixes (appear at the end of words).

We Do Strategy Observe the prefixes in the data chart. Can you identify other words with the same prefix? Pair and share. PREFIX ROOT (BASE) WORDS EXAMPLE   Micro = small scope = to see Microscope Therm = heat meter = to measure Thermometer Re = again, back flect = bend Reflection

“Forget the manual, I’ll work it out” We Do Strategy Observe the suffixes in the data chart. Can you identify other words with the same suffix? Pair and share. ROOT (BASE) WORDS SUFFIX EXAMPLE   Kinetic = motion ic = having some characteristics of… Kinesthetic “Forget the manual, I’ll work it out” Measure = dimension/quantity of something ment = an action or resulting state  Measurement Electromagnetism = electric and magnetic fields and their interactions Ism = action or practice, state or condition, principles… Electromagnetic field

You Do Strategy (BYOD Integration) Directions: Use the picture clues, your background knowledge, and a dictionary (http://www.dictionary.com/browse/ism?s=t) to research and complete the data charts on prefixes and suffixes below. PREFIX ROOT (BASE) WORDS EXAMPLE   _____ = ____ ROOT (BASE) WORDS SUFFIX EXAMPLE   _____ = ____

You Do Strategy (BYOD Integration) Directions: Use the word bank, your background knowledge, and a dictionary (http://www.dictionary.com/browse/ism?s=t) to research and complete the data charts on root words, prefixes and suffixes below. PREFIX ROOT (BASE) WORDS SUFFIX   chem  change scribe type

Independent Practice Refer to the index of your science text- book. Locate ten (10) specialized vocabulary terms that you are able to dissect, based on the strategies discussed in this power-point presentation. Create a data table to identify and record their root words, prefixes and suffixes found in the words that you have chosen.
