DNA is like the fingerprint of genetics. A quick lesson introduces the topic of DNA sequences with a mystery about an endangered species. The lesson shows how DNA extraction, replication, and sequencing often provide undeniable evidence...

Match up the DNA code. Pupils read the website from the American Museum of Natural History about how DNA can determine whether a skin is from a particular type of reptile. Using the same technique, learners match up products with the...

Placement of parentheses is paramount. Scholars adjust the location of parentheses in a numerical expression so its value matches a given value. A slider interactive helps with this task.

Cancerous tissues contain more water than normal tissue, which causes the cancerous tissue to resonate longer on the screen and be seen. High school learners can see how MRIs detect tumors in someone's head. Radio transmitters emit their...

Calling all science sleuths! A patient appears to have a disease eradicated years ago—how do you treat it? Scholars must research the illness, the possible causes, and find a cure before the disease spreads and wipes out the entire city....

Virochips detect and identify viruses at a higher rate than other tests. Show young scientists how Virochips work to identify existing viruses. They analyze results demonstrating mutations or the evolution of viruses and view videos...

Scientists detected exoplanets by measuring how the brightness of stars changed over time. Young astronomers interpret and analyze the same data that led to exoplanet discoveries. They learn to apply light curve graphs and connect the...

Elementary scholars become Sherlock Holmes to analyze a lithograph showcasing the Boston Tea Party. Scholars view the image with some pieces missing and must write an observation. Individuals are then shown the whole image and asked to...

Don some detective caps and delve into the past to explore the evidence left behind after the attack on Pearl Harbor. An interesting activity uses primary sources to explore how the United States Navy was caught off guard and how the...

Young historians turn into detectives in a thought-provoking activity on the Challenger Explosion. The activity uses an image of President Reagan watching the Challenger explode on live TV to help academics practice historical analysis....

Young detectives delve into the past in an exciting series exploring immigration. The activity uses primary sources to teach elementary scholars historical analysis. Academics read records to understand the life of Motel Garber, from...

The tone is easy to hear but more challenging to detect in written texts. Users of this interactive learn how to closely observe the diction and words writers use to convey their feelings about their subject. They examine passages that...

A series of interactive exercises provide users with the ammunition they need to detect logical fallacies and defend themselves against persuasion. Learners read about 11 types of logical fallacies and identify the type used in sample...

It makes sense to sniff out a good lesson on the sense of smell. Here is a six-slide presentation that can be a strong component to that lesson! With photographs and expository graphics, life scientists find that smell is the detection...

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,...

Spin into a dicey experiment. Pupils use a spinner or a pair of dice to determine the experimental probabilities of each outcome. The interactive allows for either, one, five, or ten consecutive experiments. Using the applet, learners...
