Seventh graders learn how living things are organized — cells build tissues, tissues build organs, organs build organ systems, and systems build an organism — each level cooperating to keep the body alive.
Students will be able to…
Your body is made of trillions of cells — but they don’t work alone. How do individual cells combine, step by step, into a whole living, breathing you?
Project each item and have students order and identify the levels. The tool explains how cells build up to a whole organism.
Tap any phase to open the teacher moves and student actions.

Preview the three formative checks. Tap “Sample answer” to see what mastery looks like — hide them before you print for students.
Have students trace one organ system (like the digestive system) through all its levels, from cells to the whole system. A printable levels-of-organization sheet is in the Science library.
Tap a card to flip it, then rate whether you knew it. Built from this lesson’s vocabulary.
