Match these Science Words with their Meanings :

Instructions: match the meanings on the left with the science vocabulary on the right. Several words are related-- a verb and noun from the same family. So choose the verb if the definition starts with "to ___."  Choose a noun if it asks for a thing (a or an _____.) The first one is done as an example.

When you have finished matching, click "check" to see how many you knew.

Note: the matching still works, but the checking function is broken. Until I can det it fixed (if possible), I've added the answers below the Category Answers.

A few explanations for words with more than one use:

Function and monitor can both be used as nouns as well as the verbs given above. Function can mean use or purpose. (It also has a specialized mathematical meaning.) 

A monitor is a machine that measures or 'watches' what's happening. A baby monitor carries the sounds the baby makes to his/her parents in another room. A computer monitor is the part of a desktop computer that you look at-- the screen and frame.

Formula sometimes means a pattern of words always used together.
