The main objective of this lesson is to find the density of an irregular shaped objects. This is a fun lab, which is easy for the instructor to setup and implement. This lab report is ideal at the end of a density unit.
Objectives – Students will be able to:
• Apply their understand of density, mass and volume in a lab setting
• Utilize mathematics skills to calculate density & volume
• Create a graph that displays summative data
• Predict outcomes, collect data and draw validated conclusions
The attached Water Displacement Lab will take place over two periods of consecutive class meetings.
A summative assessment will be conducted for each student in the form of individually completed, written lab papers that will be assessed by the teacher and assigned a grade.
Standard 1: The Scientific Process: SCIENTIFIC INVESTIGATION: Discover, invent, and investigate using the skills necessary to engage in the scientific process
• Design and safely implement an experiment, including the appropriate use of tools and techniques to organize, analyze, and validate data
• Defend and support conclusions, explanations, and arguments based on logic, scientific knowledge, and evidence from data
• Communicate the components of a scientific investigation, using appropriate techniques
Standard 7: Physical, Earth, and Space Sciences: FORCE AND MOTION: Understand the relationship between force, mass, and motion of objects; and know the major natural forces: gravitational, electric, and magnetic
• Forces of the Universe - Explain the relationship among the gravitational force, the mass of the objects, and the distance between objects
