In this radiation worksheet, students calculate the distance of a satellite in orbit to determine the placement of a radiation detection device. This worksheet has 2 problems to solve.

Students identify the short /o/ sound in this lesson. They discover that the "o" is shaped like a magnifying glass, and are "detectives" looking for the /o/ sound in words. They listen to "No, David!" and identify the short /o/ sound...

Eighth graders investigate how to compose music for a detective program. The goal is for them to discover the method needed. The idea was simple, they were told to compose the music with emotional tension that climaxed and then relaxed...

Pupils perform a simulation of the workings of an electron microscope to discover that the resolution will need to improved to detect objects in the nano-scale. They use wooden dowels as detectors to determine the shape of objects in...

High schoolers explain that planets actually orbit the center of gravity of the solar system, and that distant planets may be detected by motions of their central star around the centers of gravity of their planetary systems.

Learners explain how Hipparchus, around 130 BC, used a shift in the predicted location of a lunar eclipse to detect a slight shift in the path of the Sun around the sky. They examine the elliptical orbit in which the Earth travels around...

Young scholars study the structure and habitat of the hydra in this lab lesson. Students determine if the hydra can be used as an indicator to detect pollution from automobile exhaust.

Here's a five-star lesson plan in which inquisitors conduct sophisticated experimentation with cellular respiration in plant seeds. Placing seeds in a closed system they measure the amount carbon dioxide produced and relate it to...

A fabulous lesson on the life of Clara Barton awaits your class. They describe how Clara Barton founded the American Red Cross, and the role it played in organizing help for those in need. Additionally, young historians explain how...

Students explore paper rockets, learn about the Apollo Program and Apollo spin-offs, and use simple office supplies to design and create a new useful product. This amazing plan is incredibly well written and leads students through a...

Young scholars identify how they are feeling and deal with feelings constructively. In this conflict resolution lesson, students explore their feelings through discussion. Young scholars read and complete the What Can I Do? e-sheet....

Did you know that honey bees dance to communicate information? Do you know why bees use hexagons to build their hives? The Honeybee Man, Brilliant Bees, and Show me the Honey provide background information on how honey bees communicate....

Who would not want an opportunity to taste jellybeans in class?  During this investigation, life science learners hold their noses as they take a taste test and find that our perception of flavor is connected with our sense 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...

In this everyday editing, learners correct grammatical mistakes in a short paragraph about Miranda Rights. The errors range from capitalization, punctuation, spelling, and grammar.

There is a scallop that relies on sight so much that it actually has more than 100 eyes! There are many species that rely heavily on one sense or another. An online interactive resource has youth read about several of these animals. The...

Take the first step into graphing sequences. Learners set the starting number, multiplier, add-on, and the number of steps for a sequence. Using the inputs, the interactive calculates and plots the sequence on the coordinate plane. Users...

Caesar ciphers hide secret missives. A simple interactive lets users encode and decode hidden messages. The cipher method here is the Caesar shift.

Let coordinate pairs show you the way home. Scholars plot houses on a coordinate plane with given coordinates using an interactive app. Alternatively, they can identify the coordinates of houses already plotted on a coordinate plane.

Avoid the mines and win the game! Young scholars direct a robot through a minefield by plotting points. Their goal is to reach the target in as few moves as possible.

Fly through graphing functions with the Function Flyer. Young mathematicians use an interactive to graph different types of functions. A set of exploration questions has users investigate patterns in functions.

Sketch graphs with the Graph Sketcher. Scholars graph functions on a coordinate plane. An interactive makes it as easy as inputting the function and clicking a button.

Time to crunch the numbers! Young scholars use an interactive number cruncher to practice operations with whole numbers. They input a number and watch as the number cruncher produces the output and then use the data pairs to determine a...

What information can come from a box? Learners choose a data set to display as a box plot and decide whether to include the median in the calculation of the quartiles, show the outliers, and change the scale. To finish the lesson,...
