Students follow the steps of the engineering design process as they design and construct balloons for aerial surveillance. After their first attempts to create balloons, they are given the associated Estimating Buoyancy lesson to learn...

This website gives a great lesson plan for helping to understand the geography and physical environment of the Philippines. Map and map quiz are included.

Five lessons about the study of fluid mechanics. The unit concludes with students applying what they have learned to determine the stability of individual above-ground storage tanks given specific storm conditions so they can analyze...

Engaging hands-on science lessons for grades 2-6 on the properties of different materials.

[Free Registration/Login may be required to access all resource tools.] Definition of buoyant force and how weight and density relate to buoyant force and the ability to float.

Through exploring the phenomenon that it is easier to float on salt water than on fresh water, students will develop a conceptual model for molecules and how the arrangement of molecules affects density.

This lesson will demonstrate how to compare a calculated density from and experiment to the "actual" density reported in reference sources. It is 3 of 3 in the series titled "Percent Difference Calculations."

This lesson plan helps students discover the relationship between temperature, salinity, and density in coastal marine waters. Students access and retrieve water column profile data from the NANOOS and/or the WA Department of Ecology's...

[Free Registration/Login may be required to access all resource tools.] Batteries have both an ideal internal voltage and a terminal voltage, which is less due to internal resistance. This lesson presents sample problems and a video...

This lesson focuses on predicting chemical reactions using The Group 1 elements in the Periodic Table are known as the alkali metals. They include lithium, sodium and potassium, which all react vigorously with air and water. It provides...

An interesting lesson that taps into students' interest in crime solving and forensics. Students examine glass fragments and their density to help them solve a crime.

As part of the study of Matter, the students will determine the density of standard percent sugar solutions through hands on experimentation. In laboratory groups, students will graph a standardized curve of the experimental data. The...

This lesson helps students understand the variables that influence the abundance of phytoplankton. Students will make predictions about the timing of the spring phytoplankton bloom in the Gulf of Maine. Furthermore, data from buoy...

This lesson plan is a great way to show convection currents in water. Students will see what happens to water as it gets warmed.

Students will learn the concept of volume by determining the amount of sand that is needed to fill the long-jump pit at their school (or any rectangular- or square-shaped container). This lesson plan will explain the importance of...

In this lesson, the students will discover the relationship between an object's mass and the amount of space it takes up (its volume). The students will also learn about the concepts of displacement and density.

Expanding on the topic of objects in motion covering Newton's laws of motion, acceleration and velocity, which are taught starting in third grade, learners are introduced to new concepts of speed, density, level of service (LOS) (quality...

The concept of random variables is the focus of this lesson, including definitions of discrete and continuous random variables. Discussions on discrete probability distribution and density function are included, along with expected value...

An engineering challenge where students create small-scale models from which their testing results could be generalized to large-scale latex tubing for a hydraulic accumulator. They brainstorm ideas about how latex can be used in a...

An easy to do activity that investigates density and solubility. The activity is presented in lesson plan format that meets NSES standards.

[Free Registration/Login Required] This lesson is the third of three lessons. It covers the physical changes of matter and explains how chemical changes can be detected.

This irrational number, pi, has an infinite number of digits, so we'll never figure out its exact value no matter how close we seem to get. Reynaldo Lopes explains pi's vast applications to the study of music, financial models, and even...

[Free Registration/Login may be required to access all resource tools.] Discover how scientists learn about Earth's interior using seismic waves, meteorites, density, and the magnetic field. Additional resources are available for download.

[Free Registration/Login may be required to access all resource tools.] How different densities of water drive ocean currents.
