Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

A scenario is presented for chemistry techs to address. Using titration techniques, they must analyze hydrogen peroxide solution samples. They evaluate accuracy and precision in the process. They also gain experience consulting the MSDS...

Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools. 

Examine the behavior of energy as water freezes and melts. An engaging activity provides a hands-on experience to learners. Collaborative groups collect data and analyze the graphs of the temperature of water as it freezes and then...

Students measure a variety of objects using the appropriate measuring tool. In this measurement instructional activity, students explain the importance of accuracy and precision in collecting data. They discuss the difference between the...

Hold a free-throw shooting challenge in your engineering class! Each team must design a contraption that will fire off a "robot arm" or, more specifically, a catapult, to send a Ping-Pong ball into a basket. Use this as an opportunity to...

Students define accuracy and precision, and differentiate between the two terms, apply the concepts of accuracy and precision to a given situation and correctly apply the concept of significant figures to measurement and mathematical...

Students investigate hot melt glue using a hot melt glue gun as an an injection molding simulator and a melt index viscometer. They evaluate the effect of heating and cooling by weighing the glue extruded over a constant time period.

Investigators collect the carbon dioxide produced when an antacid tablet is activated and identify what alteration produced the most gas. They also collect the gas in a buret in order to practice precision. Then they choose between two...

There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

Students conduct qualitative and quantitative investigations based on the interaction between water and various polymers. They determine the percent moisture contained in various plastics along with a qualitative procedure to determine...

Long considered the symbol of safe harbor and steadfast waiting, the lighthouse gets a mathematical treatment. The straightforward question of distance to the horizon is carefully presented, followed by a look into the...

The accuracy required by the design and measurement of an Olympic running track will surprise track stars and couch potatoes alike. Given a short introduction, the class then scaffolds into a detailed analysis of the exact nature of the...

Students examine "masterpieces" and mass-produced objects as they discuss humankind's inventiveness and creativity. They also analyze the role of problem solving in the creation of masterpieces and mass-produced items.

The difference between accuracy and precision is fundamental for high school science learners. Using test kits for nitrate concentration in water, they compare readings with each other. They consider the accuracy, precision, and bias of...

Get ready to apply yourself! Lesson four in a series of five college and career readiness lessons introduces the basic parts of a job application. Pupils discover the necessity for good references and create a master job application for...

We use basic units of measurement to break down things and communicate clearly. The first lesson plan in an 11-part series teaches the proper way to measure various items. It starts simply with measuring the dimensions and areas of...

Advanced lab apprentices prepare zinc and copper solutions to which they will compare the same minerals from a multivitamin. Using absorption spectroscopy, they analyze the contents of the multivitamin for concentration. This lab can be...

Can people really measure time just by using the sun? Scholars venture outside on a nice, sunny day to build sundials and learn how people measured time 600 years ago. The class builds two different sundials while gaining practice with...

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...

Here is a beautifully designed volleyball lesson plan on the forearm pass/bump and overhead pass/set. It includes a detailed multimedia presentation and set of instructional guidelines, skill cues, and lists of strategies for...

Challenge readers to read closer in an activity based on the Socratic questioning strategy. As kids read Antoine de Saint Éxupery's The Little Prince, they use sentence starters to ask deeper questions about the text, and...

Investigating the large numbers of science is the task in a simple but deep activity. Given a one-sentence problem set-up and some basic assumptions, the class sets off on an open-ended investigation that really gives some...

Throughout history, newspapers have reported the events of the day as they unfolded. Using primary and secondary sources from World War I, scholars uncover how the American people learned of the events of the War to End All Wars. History...
