Science Friday® is produced by the Science Friday Initiative, a 501(c)(3) nonprofit organization.
A celestial event, citizen science, and a variety of natural wonders drew observations in week 2 of Science Friday's Science Club.
We observe: you're amazing! Staff picks from the first week of Science Club's #ObserveEverything
Go out and observe something interesting! Submit your in-depth observations with the hashtag #ObserveEverything.
Can you match each jumping spider dance to its vibratory song?
Use two play dough recipes to create "squishy circuits" and explore electricity.
Three approaches for using images as gateways to instruction in grades 4-16
In this lesson from the Chemical Educational Foundation, apply the concepts of pressure and Newton's laws of motion to build balloon rockets.
Add some pizzazz to your favorite clothing and accessories using some wire, tape, a battery, and an LED.
In this activity from Science Buddies, you will burn some metal salts to investigate what colors they make, then you'll explain to your family and friends how fireworks colors are made!
In this activity from Science Buddies, kids will create their own hula hoops and investigate how the hoops' masses affect how they spin. Which do you think will spin better, a heavy hoop or a lighter one?
In this activity from Science Buddies, you will experiment with how a kite's tail affects how it flies.
Experiment with the relationship between boiling point and the Leidenfrost effect using different aqueous solutions, a metal pan, and a little baby powder.
Create a model eardrum to visualize sound vibrations, and then use a smartphone to identify your model’s natural frequencies.
Learn how insects have inspired engineers to make a robot that walks on the surface of water. Design your own water-walking critter using thin wire, and test its effectiveness: how many paperclips can it hold up using surface tension?
Use the physical characteristics of ice to determine where and how several mystery samples could have been frozen.
Perform an experiment to determine whether smooth or wrinkled fingers are better at holding wet objects. The experiment requires only a water bottle, paperclip, and plastic ruler. Downloads: Video, student data sheet, illustrated instructions
By building their own pinhole camera, students will learn how cameras, telescopes, and their own eyes use light in similar ways.
Explore color by creating color-filtering glasses using paper and tinted cellophane.
In this activity, students will discuss the differences between the Bear Creek Wind Park and Bergey Windpower turbines. Students will learn the basic parts of a wind turbine and then build their own model wind turbine out of recyclable materials. Students...
In this activity, students will learn how an electromagnet works by making a simple one. Using this knowledge, students will design a diagram to make a working speaker using household materials. Then students will follow instructions on one method of ma...
Buildings that are called “green” or “environmentally sustainable” are designed to use energy as efficiently as possible. In Missouri, Washington University’s Tyson Living Learning Center achieves sustainability by incorporating green technologies in diff...
In this activity, students will use household materials to investigate and explore how the release of carbon dioxide gas from a chemical reaction can cause a small-scale explosion. Students then will experiment with variables to determine which factors la...
In this activity, students will perform several experiments, using simple materials to explore the properties of reflection and refraction and how they work in telescopes.
Astronauts are allowed to bring special “crew preference” items when they go up in space. NASA astronaut Don Pettit chose candy corn for his five and a half month stint aboard the International Space Station. But these candy corn were more than a snack; P...
