Twelve body systems words are matched to meanings, then used in sentences, on this 3-page 5th grade science worksheet. Part 1 lists cell, tissue, organ, system, oxygen, carbon dioxide, nutrients, joint, tendon, artery, vein and nerve beside twelve lettered definitions. Part 2 gives eight sentences with a blank, such as a knee being a joint, and a 12-word bank. The answer key is on page 3.
“Define key words for the human body, from cell and tissue to organ and system.”
Part 1, items 1 to 4.
“Use words about breathing, blood and movement in a sentence.”
Part 2 sentences on oxygen, carbon dioxide, nutrients, artery, tendon, joint and nerve.
Twelve words numbered 1 to 12, each with a short blank, sit beside definitions lettered A to L in a different order. Students write the letter of the matching definition.
A word bank of all twelve words sits above eight sentences. They include a nerve sending a warning from a hot pan, a tendon attaching the calf muscle to the heel bone and the lungs pushing out carbon dioxide.
Each word with its letter and the definition repeated, then the eight sentence answers in a row.
Before the unit
Hand out Part 1 as a preview. Cell, tissue, organ and system form a ladder students will use all unit, so go over items 1 to 4 together.
Artery and vein
Items 10 and 11 are a pair students tend to swap. Draw a heart on the board and show which way the blood travels in each.
Unused words
Part 2 has twelve words and only eight blanks, so tissue, organ, system and vein stay unused. Ask students to write a sentence for each leftover word.
