Scholars go on a hunt to locate objects that best fit the measurements to create an eye-catching scale model of the solar system. 

Young scientists begin a field journal by following four steps. A real-world example of an entry showcases the different parts, including location, date, drawings, and more. 

Engage in a shady activity to practice measurement techniques. Classes venture outside to collect measurements of various trees, using different strategies to measure the height, trunk circumference, width, and crown size. Then they...

One step at a time, pupils practice their measurement techniques as they analyze their stride length. They design their own procedures for measuring and relate their stride measurements to the distance traveled by making calculations.

Sound the alarm about a great resource. Scholars first build a simple circuit to learn the basics about electric currents. They then design an alarm system in which a buzzer activates when pressure is applied to a doormat.

Creatively combine clothes and conductors. Pupils learn how to use conductive thread to make electric circuits. They apply the thread to design and build an accessory item with LEDs.

Knead a resource on electric circuits? A fun activity teaches future scientists about conductors and insulators. They prepare conducting and insulating dough and use them to make creatures that light up.

The lesson is real—even if the computer code isn't. Scholars learn about pseudocode, which simulates computer code using everyday language. They write pseudocode for simple actions, then have classmates guess the action from the written...

Using gloves, shortening, tape, and a lot of ice, participants experience the feeling of having blubber. The experiment's eight steps follow an informative page about blubber and animals that have it.

Scholars follow eight steps to create a flipbook and discover key facts about mammals' locomotion.

Scholars follow five steps to make personalized Earth-themed stationary. Personalization includes name and returns address.

Seven pages offer scholars the opportunity to learn about North American mammals and boost their coloring skills. Animals include brown bears, beavers, jackrabbits, wolves, jaguar, and Dall sheep 

Five steps walk scholars through the process of drawing a Monarch butterfly. Participants research the insect, make observations, trace, then color. 

Create an edible model of the Earth using crispy rice cereal, marshmallows, and chocolate, yum! Model layers include the outer core, inner core, mantle, and crust. 

Field guides are a like a window into an ecosystem. Young scientists collaborate to create their own field guides by recording observations from a local ecosystem. Ideally, they collect information over time to create a more complete...

Enjoy a hands-on lesson that will certainly hold water with your classes. Young scientists design an experiment to determine the materials that absorb water the best. They test both man-made and nature-made materials and conduct...

Things should heat up during a hands-on lesson exploring solar energy. An enlightening activity challenges young scientists to design a structure that collects solar energy efficiently. They keep track of temperature data over time and...

There's no way a child can operate heavy machinery ... right? Pupils examine a photograph of a child operating a loom at mill to learn about child labor and its impacts. Prompts provoke thoughtful discussion or fuel a writing exercise.

Saving sugar, growing crops, and not eating meat sound like small things, but they were a huge part of the home front effort during World War I. Photographic evidence of civilian struggles during the war, along with a matching game,...

What makes the ocean blue but a glass of ocean water nearly colorless? Investigators prepare tubes of water to examine the color of water. Scholars discover the relationship between light absorption, color variations, and water depth as...

Jump into the action and help antibodies defend against an antigen attack! Investigators match antibodies with antigens to model the body's identification and recall of specific pathogens. Young biologists also recognize that each...

Make pathogens and the body's defense systems come alive for young biologists in a hands-on activity. Investigators model the skin's protection against infection by observing and comparing changes in a punctured tomato and an intact...

What's with all the numbers on plastic products? Learners complete an in-depth analysis of the physical properties of the different plastic types. They connect the properties of the plastics to uses and test their observation skills by...

Changes to habitats mean changes to resources. Groups examine aerial maps to predict areas of low and high plant resources. After formulating a plan, they visit the areas to collect data about the plant resources and then share their...
