A Matter of Splatter
Source Institutions
In this math-based activity, learners will experiment to find how height and angle affect spatter and then use this knowledge to solve a crime.
We all Scream for Ice Cream
Source Institutions
In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.
Self-Portrait Silhouettes: Activity 1
Source Institutions
In this activity, learners make a photographic image--without a camera!
Gymnast
Source Institutions
In this physics activity, learners build a toy with a figure that spins around like a gymnast on the high bar.
How Do Antacids Work?
Source Institutions
You just ate a big meal and feel heartburn coming on. You take an antacid and feel better. Why? Heartburn is caused by stomach juice (an acid) burning the esophagus.
Confetti Launcher
Source Institutions
Hooray! In this design challenge activity, learners invent a device that launches a spoonful of confetti into the air. Learners are encouraged to create the biggest cloud of confetti possible.
Science at the Waterpark!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.
Fruit Juice Mystery
Source Institutions
In this chemistry challenge, learners work to figure out which of four juices are real, and which is just food coloring and sugar.
Wind Tunnel
Source Institutions
Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.
FlyBy Math: Distance-Rate-Time Problems in Air Traffic Control
Source Institutions
In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.
Seedy Travelers
Source Institutions
In this activity (on pages 18-28), learners explore how the shape of seeds affects how they are dispersed by wind, birds, ocean currents and other means.
Scribbling Machines
Source Institutions
In this activity, learners explore electronics and motion by making a Scribbling Machine, a motorized contraption that moves in unusual ways and leaves a mark to trace its path.
Investigating Starch
Source Institutions
In this activity (on pages 10-15), learners investigate starch in human diets and how plants make starch (carbohydrates) to use as their food source.
Chemistry is Colorful
Source Institutions
In this activity, learners explore materials through paper chromatography.
Stretch the Chain and See the Light
Source Institutions
In this activity, learners use their strength to light a light bulb. A chain made from paper clips is placed in series with a battery and flashlight bulb.
How Boulders Are Born
Source Institutions
In this activity, learners review and discuss weathering, erosion and mass wasting, to gain a stronger understanding of how Hickory Run’s Boulder Field was formed after the Laurentide Continental Glac
Moving Without Wheels
In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.
Safe Food Preparation
Source Institutions
In this activity about food safety and nutrition, learners investigate safe food preparation by making fruit ice cream.
Engineer A Bird Feeder
Source Institutions
In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.
Law of Conservation of Mass
Source Institutions
In this chemistry activity, learners explore whether matter is created or destroyed during a chemical reaction. They will compare the weight of various solutions before and after they are mixed.
