Density Lab Activities
Students participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.
Curated OER
Using Density to Identify Wood Types
Young scholars identify different woods based on their density. For this density lesson, students use a triple beam balance to find the mass and a metric ruler for the volume. They look through various wood blocks and identify what type...

Measuring Yourself Using the Metric System
Learners measure using the metric system. In this geometry instructional activity, students solve problems using grams, meters and liters. They convert between the US units of measurements and the Metric System.
Curated OER
Mass, Volume and Density
High schoolers compare and contrast the mass, volume, and density of various objects. They use a triple beam balance, measure and record the volume of a cup of water, and discuss the results.
Curated OER
Law of Conservation of Mass
Students work in small groups. They grab a handful of ice, and place the ice in an empty beaker of ice using a triple beam balance. Students heat up the beaker of ice over a hot plat until the ice has changed into water. They measure...
Curated OER
Practice with Mass
Fourth graders investigate the weight/mass of a number of items using grams, and equivalents. They examine the use of a triple beam balance before massing objects including oil and water. They go over the weights they amassed and weigh...
LABScI
Cell Diffusion and Permeability: The See-Thru Egg Lab
Create a model to study a microscopic phenomenon. The seventh of 12 lessons uses an egg (without its shell) to represent a cell membrane. Using different solutions, learners explore the concept of cell diffusion. They monitor...

Project Geode
Young geologists attempt to predict the appearnace of a geode's internal structure based on how it looks from the outside, its mass, and its physical characteristics. In this geologly instructional activity, learners use scientific...
Curated OER
Balancing Bottles
Students explore the Law of Conservation of Matter using effervescent tablets. In this mass and energy instructional activity, students investigate how mass is conserved in the reaction of effervescent tablets and water. They will...

"Mummies--The Great Cover Up"
Students wrap their mummy, use canopic-style jars for the preserved chicken organs and design and decorate a sarcophagus. They collect data by weighing, measuring and graphing their "mummy" and its organs.
Curated OER
Force & Acceleration
Students investigate the effects of weights on the motion of a toy car. In this force and acceleration lesson plan, students use different weights, a toy car, a paper clip and string to determine how a car will move as different weights...
Curated OER
Measure Twice
Students measure a variety of objects using the appropriate measuring tool. In this measurement lesson, students explain the importance of accuracy and precision in collecting data. They discuss the difference between the two.
Curated OER
Rate Determining Step and Catalysts
Students investigate the rate determining step in a chemical reaction and how catalysts effect reactions. In this rate determining step and catalyst instructional activity, students work in groups to perform 5 tasks. They rotate each...
