This resource teaches students the concept of buoyancy. Students will learn why objects float and sink through two science mini units lasting 5-7 days each. The overall unit is based on backward lesson design and is user friendly for teachers. Students start with basic concepts of sinking and floating and move into more complex labs of building boats that hold cargo. Archimedes Principle is introduced. This resource includes material lists, teacher notes, lab instructions, student lab handouts, informative reading and writing tasks, math tasks, observation tasks, lab testing, engagement activities and assessment ideas. This resource is classroom ready. Very easy to adapt for your class.
Science Mini Unit 1 Outline “Sink or Float?”
Engage: A simple, fun engagement activity that creates student curiosity “Sludge Fleas”.
Explore: Students explore through Sinking and Floating Lab Part 1 (no prior knowledge needed).
Explain: A teacher read aloud, vocabulary review followed by a discussion (charting and/or note taking) on the concept of buoyancy, explanation of Lab Part 1 and Sludge Fleas. Introduce students to Archimedes Principle and how the concept of buoyancy was discovered.
Elaborate: Using learned knowledge students explore through Sinking and Floating Lab Part 2, Different objects will be tested by students. Students will test objects to see if they are buoyant or non-buoyant.
Evaluate: Comparison of predictions of Lab Part 1 and Lab Part 2 by students. Students write or draw what they learned about buoyancy.
Science Mini Unit 2 Outline “Boat Olympics”
Engage: Video clip “How to Float Large Ships.”
Explore: Students will create an aluminum boat that holds cargo. Their goal is to design a boat that will hold the most pennies or other objects.
Explain: “Why a boat floats?” explanation. “Archimedes Solves a Problem!” close/critical student reading.
Elaborate: Using knowledge learned, students will design a clay boat that will hold the most pennies or other objects.
Evaluate: Assessment ideas given: “How boats float?”
