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.

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...

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 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 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...

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 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.

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...

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...

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.

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...

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 watch the teacher do a demonstration of density with diet and regular soda. Note: try this first, as different types of artificial sweetener have different densities. Students discuss density and volume. They discuss "Relational...

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.

Learners determine the best chocolate chip cookie. In this comparison investigation, students create a quantitative scientific study to determine the best chocolate chip cookie using the steps of the scientific method.

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...

Third graders explore and identify the tools that can be used to measure length, mass/weight, and volume. They discuss how things are measured using different units, and observe the difference between the English and the Metric systems....

Students collect data from measurements and weights for this experiment. In this algebra instructional activity, students analyze graphs they create form their data to find the expression representing the data. They label which graph...

Seventh graders, in groups, complete an Isotopes model and notice that atomic masses are decimal numbers. These masses are an average of all the isotopes of that element.

Young scholars will design a scientific investigation. In this engineering design lesson, students will set up an investigation, collect data and form a conclusion about bridge design. They will use common household items to construct...

Students use scientific method to determine cost-effectiveness of air freshener, and create PowerPoint presentations to share their results.
