Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting instructional activity, scholars explore buoyancy and the properties of air and water. They test...

Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...

What do we do when a dive is too dangerous for humans to accomplish? Send in the robots! Middle school scientists get acquainted with several different models of submersible robots in the second lesson of six from NOAA. Lab groups then...

Different substances can have different densities, but can the same substance have different densities? Lesson explores the effect of temperature on the density of water. Extension idea connects the concept of how melting ice in lakes...

We know solids have a density we can measure, but what about liquids? Lesson explores this concept and allows scholars to explore the relationship between volume and density. Graphing and analysis questions round out the activity. 

We have formulas for finding the volume of geometric shapes, but what if the shape is irregular? Lesson describes how to find volume through water displacement. After a demonstration, scholars practice in small groups. Then analysis...

Density: the reason a giant pumpkin will float, but a tiny cranberry won't. Lesson begins with a demonstration of two of the same-sized cubes having different densities. Then pupils take eight cubes, each of the same size, and have to...

Water is the only molecule on Earth that can naturally exist in all three states of matter. The interactive simulation shows different molecules changing states of matter with the addition or removal of heat. Learners then see how...

Paper or plastic? Explore the environmental effects of using plastic bags through mathematics. Learners manipulate worldwide data on plastic bag consumption to draw conclusions.

Full of problems with polygons, angles, lines, and triangles, your learners get a multi-page packet that provides all they need to know. It contains many of the standard problem types as well as some more challenging questions. 

In need of an all-inclusive seventh grade math resource? Packed full of the topics necessary for Pre-Algebra the packet includes practice problems with different difficulty levels. It works great for any supplemental use needed in the...

Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on to learn the...

As Mia and RJ discuss measurement, your class is introduced to the customary and metric systems for measuring mass, capacity, weight, and length. Temperature scales are also introduced. This resource can help set the foundation for later...

What better way to start your day than with a box of oatmeal? Or what better way to start your geometry class than by calculating its volume? Eighth graders discover just how practical volume computation can be in business and in breakfast!

Which vase holds more water: a cylinder, sphere, or cone? Figure out which should be used for your sister's birthday bouquet with this practical word problem.

Everyone wants to have the biggest snow cone possible, so would that be in cone-shaped cup or a more cylinder-style cup? Hungry geometry juniors compute the volume of each in this practical task.

Listen in as Mia and Sam expound on sound. It is caused by vibrations and travels in waves. It has the qualities of pitch, frequency, and volume. This hip animation displays a graph to depict the frequency and amplitude of sound waves....

Does matter really matter? Properties of matter are discussed by Sam and RJ: mass, volume, and density. They differentiate between mass and weight. They explain how to measure these properties. Make sure to teach your class about other...

General chemistry class members engage in a mini-unit on mole conversions. Through nine lab activites with varying degrees of difficulty, they practice measuring mass and volume, molar calculations, and stoichiometry. Terrific teacher...

Mathematicians analyze the relationships between surface area and volume. They conduct Internet research, conduct various experiments, record the data in a spreadsheet, and graph the results and compare the rate of increase of surface...

A micro-unit on the phase changes of water includes three laboratory activities. Junior scientists compare the densities of ice and water, and then they do the same for cold and warm water. They examine freezing and boiling temperatures....

Give small groups handfuls of unit cubes and then dare them to build as many rectangular prisms as possible using only 12 cubes. This engaging activity serves as an introduction to the volume of solid figures. In addition to volume,...

Six straightforward word problems require learners to use customary units of capacity (pints, quarts, cups, gallons) on this assignment. In order to answer each question, they must write an explanation in the form of a mathematical...
