Does the change in energy of matter lead to a change in mass? Upcoming chemists compare the mass of equal-volume, but different-temperature liquids and materials both before and after a chemical reaction has occurred. In another...

Students identify different woods based on their density. In this density activity, 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 of...

Students weigh objects using a triple beam balance. In this mass instructional activity, students use an inertial balance made with a metal rod to measure and graph vibrations of varying numbers of pennies in a bucket. References and...

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.

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...

Young scholars 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.

Learners measure using the metric system. In this geometry lesson, students solve problems using grams, meters and liters. They convert between the US units of measurements and the Metric System.

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...

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

Students determine the mass of various "dinosaur eggs" and graph their data. In this mass, weight, data and graphing lesson plan, students measure the mass of different weighted "dinosaur eggs". They record their data and transfer it to...

Mass and density — aren't they the same thing? This activity has groups use balance beams and water displacement to measure several objects. The pupils use the measurements to calculate the density of the objects. 

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...

Explore the importance of a concentration gradient in the rates of dissolution. Using the ocean ecosystem, learners study rates of dissolution around coral reefs. A hands-on experiment helps individuals discover the effects of changing a...

Students determine the density of a material created in the laboratory and observe physical and chemical changes. They engage in a lab activity, and answer questions on a worksheet imbedded in this plan.

Fourth graders determine the amount of energy required to melt ice using a calorimeter. They calculate the Molar Heat of Fusion of Ice.

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 lesson, learners use scientific equipment to collect...

Students investigate the physical and chemical properties of a candle before and after it is lit. They conduct a burning candle experiment, and complete a KWL chart and worksheet, recording the results of the investigation.

Learners discover the property of density while participating in a lab exercise. In this scientific measuring lesson plan, pupils utilize a scale to measure the density of different metal materials. They document their work and present...

Fourth graders calculate density, compare densities of solids and liquids, measure liquids using a balance, and investigate the significance of density. They conduct an experiment to determine an order of densities, and complete a...

Fourth graders build a balloon hovercraft, take direct measurements, answer critical questions, and make calculations using the data gathered in order to see the concept of acceleration as a change in velocity. They use a worksheet...

Students explore the Law of Conservation of Matter using effervescent tablets.  In this mass and energy lesson, students investigate how mass is conserved in the reaction of effervescent tablets and water. They will discuss and...

Students determine how mass is a property of an object that can be measured, and examine how size affects mass. They work with balances and determine what units of measurement are associated with mass. Finally, they determine the...

Here is a math lab that helps young mathematicians understand the real-life meaning for vector addition. By building a model using spring scales and washers as weight, and then calculating the vector addition using two different methods,...

Middle schoolers 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.
