- Space
Scientists Say: Transit
When an object in space passes in front of a star and looks big enough to block out all the light, it’s an eclipse. When it’s smaller, it’s called a transit.
- Science & Society
Scientists Say: Forensics
When there’s blood, bones and fingerprints on a crime scene, it’s time to bring in the scientists. Their research is called forensics.
- Computing
Scientists Say: Ampere
An ampere is a unit of electric current. It’s a base unit, meaning it’s one on which all electrical calculations are based.
- Genetics
Scientists Say: Genealogy
This is the study of someone’s ancestry. It could mean finding out about someone’s family tree or the history of evolution from one species to another.
- Math
Scientists Say: Quartile
A quartile might sound like a fourth. But that’s not quite what it is.
- Genetics
Experiment: Are fingerprint patterns inherited?
Let’s investigate whether fingerprint patterns are created randomly or whether they are influenced by genetics.
- Animals
Watch out for tree-climbing crocs
What’s that up in the tree? If you live in the right part of the world, it could be a hungry croc.
- Physics
Scientists Say: Quark
These subatomic particles are the building blocks of bigger particles, including the protons and neutrons found in an atom’s nucleus.
- Animals
Scientists Say: Medullary bone
Medullary bone is a layer that forms inside bird and dinosaur bones. It’s a source of the calcium in eggshells.
- Physics
Explainer: Locating a gun with sound waves
Recording the sound of a gun from three microphones can help scientists pinpoint the weapon’s location.
- Animals
Scientists say: Hibernaculum
This week’s word is hibernaculum, the word scientists use to describe the place where an animal goes to hibernate.
- Planets
Scientists Say: Eclipse
How the sun, moon and Earth line up determines whether there’s a solar or lunar eclipse.
