How would a pendulum work on the moon or Jupiter? To answer that question scholars control up to two pendulums including their location, length, mass, and amplitude. Added controls include changing the friction and strength of gravity....

For this milkweed and monarch butterfly mania:  measuring worksheet, students use photos of milkweed plants and caterpillars next to a ruler to estimate the measurements of 10 leaves and 15 caterpillars, calculating and recording...

Three main factors determine the wave height experienced in the ocean. Scholars use a virtual simulator to alter wind speed, fetch, and duration. Each combination creates a unique wave measured in significant height.

Where did the pH scale come from? Take a deeper look at a most important measure of ion concentration using a simulated physical determination. Young chemists prepare a series of dilutions after determining a dilution factor for the...

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...

We see curved mirrors every day in spoons, rear-view mirrors, stores as a safety measure, make-up mirrors, and in novelty stores. Scholars explore the changes to an image based on the curve of the mirror, the location of the image, and...

In this data collection worksheet, students collect data about butterflies and milkweed plants and record the measurement tools they use to collect it. Students complete 2 columns.

An interactive that teaches about sonar sure sounds like fun! Junior oceanographers study the uses of sonar, past and present, in an engaging interactive. The content demonstrates how sonar works, why sound waves are a great tool...

Maps are great for helping you get where you're going, but what does that place actually look like? Geology scholars compare and contrast the features of topographical and geologic maps using an interactive lesson. The resource describes...

Physics class has its ups and downs ... especially when it involves energy concepts! Scholars analyze information to determine changes in kinetic and potential energy using an interactive resource. Realistic scenarios make connecting...

Take a look at data from a statistical lens. An interactive allows pupils to enter data set, labeling the data including the units used. Manipulating the applet, learners select the statistics to calculate that include total, mean,...

Talk about a cool tool! Convert between units with the click of a mouse using a handy online resource. Enter the starting measurement and units for quantities such as torque, speed, and inertia, then sit back and relax while the computer...

Learners, through watching a simulation, can manipulate various characteristics of different solutions focusing on acid-base solutions where pH, strength of solution, and concentration may be changed. Views may be at the molecular...

Which has the higher IQ, latitude or longitude? Longitude because it has 360 degrees! The interactive introduces the way latitude is measured and why it can never have more than 90 degrees. A handful of challenge questions encourage...

The brain is a complex organ with many different structures and functions. An interactive diagram allows learners to explore the different structures while pop-ups describe their functions. Secondary interactives show the structures of...

An interactive challenges mathematicians to round large numbers with help from a large scale that measures the weight of a blue whale. The practie's five questions include multiple-choice, fill-in-the-blank, true or false, and an open...

Different colors of the spectrum travel at different speeds through media, causing them to refract at different angles—which allows humans to see their colors. Through a simulation, pupils see how air, water, and other media bend light....

The key is in the leaves. Pupils enter data to create a stem-and-leaf plot. The resource then displays the plot and calculates the mean, median, and mode of the data. Using the plot and the calculated measures of spread, learners analyze...

In this amphibians worksheet, students click on the links in the questions about amphibians to find the answers to the questions and then come back and answer the questions. Students answer 10 questions total.

In this Ohm's Law worksheet, students answer 16 questions about electricity, electric current, voltage and electricity and they mathematically analyze a circuit they design and construct.

In this screech owl worksheet, students complete activities to learn about screech owls after reading Screech Owl at Midnight by C. Drew Lamm. Students learn how to attract owls, investigate owls in their community, and define words...

Make sure the measurement is right. The interactive provides right triangles with a missing side measurement. Pupils use the given sides and the Pythagorean Theorem to calculate the length of the missing side. After entering the length,...

Build upon and stack up data to get the complete picture. Using the applet, pupils build bar graphs. As the bar graph builds, the interactive graphically displays the mean, median, and mode. Learners finish by exploring the changes in...

Teach budding mathematicians how to square a triangle with an interactive that shows a graphical proof of the Pythagorean Theorem. Pupils alter the lengths of the legs using sliders. Using the inputted lengths, the applet displays the...
