Four Tissues, One Living Body
Grade 7 Life Science Exploring How Tissues Work Together Day 4 - Tissue Types
Today's Learning Targets
I can define the four main tissue types I can identify tissue types using structure and function clues I can explain why tissues matter in multicellular organisms Success: Match tissues to body locations and justify choices
Hook: Match Tissues to Body Locations
Write numbers 1-8 in your notebook Match each location to: Epithelial, Connective, Muscle, Nervous Star the two you feel least sure about Locations: mouth lining, skin surface, tendon, blood, brain, spinal cord, heart wall, biceps
Essential Vocabulary
Tissue: group of similar cells working together to do a job Epithelial tissue: covers surfaces and lines organs; protects and absorbs Connective tissue: supports and connects body parts (space between cells) Muscle tissue: contracts to create movement Nervous tissue: sends and receives signals to control actions
Reading Tissue Images: Structure Clues
Layers or lining = Epithelial tissue Lots of fibers and space = Connective tissue Long, banded/striped cells = Muscle tissue Branching cells with extensions = Nervous tissue
Station Activity: Tissue Detectives
4 stations: Epithelial, Connective, Muscle, Nervous 2-3 tissue sample cards per station Record: Card # → tissue type → evidence Use structure AND function clues 2-3 minutes per station, rotate when timer rings
Station Recording Template
Station: _____ Card: _____ My claim (tissue type): _____ Evidence - Structure clue: _____ Evidence - Function clue: _____ Teacher checks: vocabulary use, accurate clues, clear reasoning
Create Your Tissue Collage
Fold paper into 4 equal panels Title each: Epithelial, Connective, Muscle, Nervous Include: 1 picture, 1 body location label, 1 function sentence Add organization arrow: Cells → Tissues → Organs → Systems → Organism Fast finishers: Add example of tissues working together
Exit Ticket: Why Do Tissues Matter?
Write two complete sentences explaining why tissues are important in multicellular organisms Must use at least two vocabulary words from today Sentence starters: 'Tissues are important because...' 'For example, _____ tissue helps...'
