A PERFECT LAB to hammer home the concept of density to students of multiple abilities and in varied grade levels. A TRUE introductory blend of physical science, math, and the scientific method with an emphasis on data collection, data analysis, the scientific method, and the properties of matter.
In this lab, density is calculated for 3 objects: candle, glass marble, and a steel cube. Using basic lab materials: triple beam balance or digital scale, graduated cylinder, the objects listed above, and a calculator – students complete a comprehensive density lab in which they compare and contrast densities and make connections between the mass/volume relationship within an object.
Come explore density delivered in a variety of ways: atomic based questions, object analysis, relative density comparisons, practice problems, relationships between mass and volume, how density changes/does NOT change between different sized objects of the same material, sink versus float, density LAB experiment with provided data, density LAB experiment in which YOU collect your own data, bar graph building and analysis, and lab summary.
If one chooses the provided data, clear pictures of each object’s mass, initial volume, final volume, actual volume, and density calculations are provided. If one chooses to calculate their own data, blank pages are provided in which dry erase crayons/markers may be used.
The bar graph is open ended in that you cut the necessary length of each bar based on data specifics.
This works well for any level but is GREAT for special education students or college prep learners that need an alternative assessment and may not be great at traditional labs.
This is a thorough and DYNAMIC activity that covers a ton of information about density. This has been used as a pre-class, lab/activity, study guide, review, and assessment. This is an effective teaching tool one on one, in small groups, and as a class when using a Smart Board/Promethean Board/Projection.
A guaranteed hit all around!
A great addition to your science and math teaching library.
Cut and paste or Velcro and laminate for special education applications and alternative assessments.
Within the classroom, this activity has been consistently very successful and acclaimed by students in grades 4th – 9th within multiple types of schools - public, private, and charter.
This work has also been shared at workshops, in-services, and conferences.
Great feedback from parents, teachers, administrators, and curriculum field professionals.
Applicable to many state science assessments and benchmarks.
Has been applied to state mandated North Carolina end of year tests for science in grades 5 and 8.
Even used by teachers in New York State as a preparation for the Earth Science Grade 9 Regents Exam.
