- Physics
Staying grounded in space requires artificial gravity
On TV, people in space walk around like they’re on Earth. How can science give real astronauts artificial gravity? Spin right round, baby.
- Chemistry
Scientists Say: Alkaline
Alkaline chemicals are basic — substances that produce hydroxide ions in solution.
- Chemistry
Level up your demonstration: Make it an experiment
What’s the difference between a demonstration and an experiment? Questions, measurements and many, many replications.
- Math
Scientists Say: Pi
Pi is the ratio of a circle’s circumference to its diameter. But some mathematicians say life would be easier if we used a different ratio instead.
- Health & Medicine
Let’s learn about exercise
Our bodies — from our muscles to our brains — love a good workout. Scientists are always learning new things about exercise.
- Fossils
Scientists Say: Dinosaur
Dinosaurs emerged between 243 and 233 million years ago. While some died out 66 million years ago, others are still with us — birds.
- Physics
Getting cozy with a science experiment
Items you use in your home can inspire a scientific experiment.
- Health & Medicine
Scientists Say: Placebo
In clinical trials, scientists often test a drug or procedure against a placebo — a treatment that has no effect — to find out how well their new treatment works.
- Animals
Science and Indigenous history team up to help spirit bears
When scientists and Indigenous people work together, their efforts can benefit bears and people.
- Animals
Explainer: Black bear or brown bear?
If you see a bear, check size, shape and more to find out what type it is.
- Animals
Changing people’s behavior can make bear life better
Black bears don’t always live life on the wild side. More and more, they live near people. Here’s how people and bears can get along.
- Genetics
Let’s learn about DNA
DNA is made of two chemical chains twisted around each other. It stores information that allows cells to grow and function.
