Vocabulary Introduction
Pre-teaching essential vocabulary increases the reading and comprehension of the lesson and material presented. Most of the students can benefi
from having specific new words when learning science.

Method of introduction:
Teacher will make labels for each new word to display around the room. Students may define the words and draw pictures to illustrate the
meaning of the words. Visually seeing and then using the words correctly in their writing will solidify the application of new words in reading
and writing.
Extension activity ideas
Get many irregular objects. The teacher should pre measure the objects and label them #1, #2, #3 etc in order to match the volume with the
numbered object. Students can then participate in a “challenge” to measure all the objects’ volume. Then the teacher can see which group of
students has the most correct by checking with his pre-measured list.
Making Extra TLM’s with pupils
Assign groups of four students to work at the workstations. Show your model of a calibrated bottle, and go over the directions on
