Here is part two of a two-part instructional activity in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and...

Who pilfered the pin? Scholars practice measurement skills as they solve the mystery of a stolen pin. They measure length, temperature, and mass and determine which of select suspects committed the crime. During the STEM hands-on...

Is the sky falling? Learners use a simulator to modify the mass and velocity of asteroids and collect data on how they influence the diameter and depth of the impact crater. They use their results to draw conclusions and make predictions...

Who actually goes looking for a virus? Expose your class to the high-stakes life of an epidemiologist on the trail of the Nipah virus. Pupils engage in a short video, then examine how scientists predict, model, and find the source of...

You may not be able to take a field trip to the moon, but that doesn't mean your class can't study moon rocks. Using graham crackers as the moon's bedrock and powdered donuts as micrometeorites, young scientists simulate...

How does weather affect Earth? Learners understand the characteristics of water and make predictions about weather patterns. They recognize how water and weather affect rocks and minerals through erosion. They also learn about fossils...

How do meteorologists differentiate between droughts and dry spells? Introduce the concepts of weather forecasting and prediction with an insightful research-based lesson from the K20 series. Partners synthesize individual research from...

Will it sink or will it float? Learners predict the outcome as they drop random objects into a container of water. Then, they keep track of the results and record the data in a t-chart to draw a final conclusion.

Forensic scientists depend on their observation skills to analyze evidence down to the molecular level. Middle and high schoolers practice making observations and predictions with a series of crime scene activities, which includes a...

Can your class predict the weather? Show them how they can come close with a lesson about creating weather instruments, including weather vanes, barometers, wind socks, anemometers, and thermometers. Kids research weather patterns and...

What better way to make predictions about future weather and climate patterns than with actual climate data from the past? Young climatologists analyze data from 400,000 to 10,000 years ago to determine if climate has changed over...

Little learners experiment with sunlight and map out how light travels. Using a mirror and slotted card, they find out about items that can reflect or absorb the light. They experiment with a variety of materials to find out how light...

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

What's that silly thing spinning in the wind? It's a whirligig! Explore wonderful windy whirligigs with a STEM-based unit that teaches the science and concepts behind these gigs. Scholars discover how gravity and air resistance...

Spruce up a class reading of the children's book Joseph Had a Little Overcoat by Simms Taback with this fun series of activities. Starting with a list of reading comprehension questions and key vocabulary to address during a teacher...

In a classic activity, emerging electricians test various objects for electrical conductivity in a circuit. Each group constructs a simple circuit by following a diagram. Predictions are made and objects are inserted into the circuit,...

How does the scientific process begin? Introduce ecology scholars to scientific inquiry through an insightful, data-driven lesson. Partners examine data from an ongoing research study to determine the questions it answers. The resource...

Looking for a fresh take on traditional food/energy pyramids? Conduct an innovative activity where pupils build their own! The lesson uses research data from Gorongosa National Park in Mozambique for a real-life safari touch. Scholars...

Wolves eat better when the bunny population increases, but how long does that last? A series of 12 biology lessons uses the sixth installment to explore the predator-prey relationship between bunny and wolf populations. Young scientists...

Viewers learn about three different weather measurement tools in installment five of the 10-part Discover Your Changing World series. They build weather vanes to collect data on wind speed, barometers to determine air pressure, and...

Data, data everywhere. Challenge your class to begin thinking about data, the ways people collect information, and what we can learn from this data. Class members discuss sources of data and then individuals answer questions in the...

Young scientists create a compost bag, predict changes, and after one month, examine the bag to observe the changes that have occurred.

What is the difference between making inferences and making observations? Young climatologists refer to a PowerPoint to make observations on each slide. They record their observations in a provided worksheet before drawing a...

Three activities make up a solar system lesson that features the sun, its light, and the shadows it produces. Scholars step outside to discover the changes shadows make at different times of day, take part in a demonstration of...
