Students investigate density and salinity of water. In this density and salinity lesson plan, students find the density of objects and liquids and show the relationship between the salinity and density of water. Students add salt to...

Students explore the measurements of capacity by constructing a creative project in the shape of a man. The man has body parts that represent different units of measurement and can be used to make conversions. This is highly concrete and...

Young scholars review estimation, measurement, fractions, decimals while familiarizing themselves with a new classroom at the beginning of the year.

Ninth graders compare ancient and modern technology in water transporting. In this lesson on the evolution of the aqueduct, 9th graders build a working aqueduct model and examine its components. They explain the importance and use of the...

Young scholars examine why diffusion and osmosis happen in an egg cell.  In this diffusion lesson plan students demonstrate a semi permeable membrane.

Will the block float? Pupils take measurements to calculate the volume of various blocks of different materials. Using a scale, they determine the mass of each block and then calculate their densities. Scholars finish by ranking the...

It's assessment time! Determine your young mathematicians' understanding of elapsed time with this brief, five-question quiz.

How much time does it take to jump over three balloons? Pupils calculate the speed of tasks that require different motions. They determine motions for tasks such as walking, skipping, hopping, and jumping before creating a...

Every child's dream: stuffing as much candy into a bag as possible. Doing this, though, requires a nice sturdy bag. Scholars design the sturdiest bag they can and test the limits of those bag using a sweet treat!

In this planet models learning exercise, students use the radius of a given planet and its mass to answer questions using a model of a planet with a given radius. They determine the volume of the planet's inner core, the volume of its...

In this worksheet for making standard solutions, learners read about making a standard solution and perform the three background calculations necessary to make one. Students then make a solution by weighing a given substance, adding it...

Students explore tessellations. In this shapes and geometry lesson, students describe the attributes of many of the shapes displayed on an Elmo. Students create examples of tessellations using pattern blocks.

This is the grown-up version of the classic "float an egg in salt water" experience, plus an experiment in soap making. High schoolers explore density, but more importantly, practice accuracy, precision, and the use of significant...

Certain things just do not mix, including liquids of varying densities. Learners collect data to determine the densities of several liquids. They then use the density information to predict the type of liquid.

Learners identify the stages of the water cycle. They listen to the book "Magic School Bus: Wet All Over," examine the Build Your Own Water Cycle website, predict and measure the amount of water in a jar for a week, and read a short play...

In this atmospheric carbon dioxide instructional activity, students use a graph of the Keeling Curve showing the increase in atmospheric carbon dioxide since 1958 to solve 6 problems. They determine the rate of increase, the find the...

Students study the concepts of motion, velocity, and acceleration through graphing their own movement using LoggerPro. They explain the difference between speed and velocity using the weather vane example. They discover the difference...

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

Students compare and convert units of measurement within the United States customary system and within the metric system by baking cookies. Students discuss how to double the cookie recipe, how to make only half of the recipe, and how to...

Learners examine concept of time, and explore difference between analog and digital clocks; students make art project to represent time and create a time-story problem and solution.

With the help of the Area Officers and Perimeter Patrol, you learners will develop a better understanding of area and its relationship to perimeter. First, they view a video clip from Cyberchase, and then they visit a website to...

Explore measuring various objects using square centimeters. Learners create various shapes using five centimeter cubes, calculate the area in square centimeters of different classroom objects, and discover who has the largest mouth,...

In this chemistry review worksheet, students identify chemical changes, isotopes, ions, and chemical bonds. This worksheet has 32 multiple choice questions.

In this density graph worksheet, students graph data displayed in a chart. Students also calculate the density of each metal shown in the graph. Students answer questions about which detail is more dense.
