This theory describes how the universe began as a rapid expansion 13.8 billion years ago.
What is the Big Bang Theory?
DAILY DOUBLE!!! The solar system formed from a cloud of these two things.
What are gas and dust?
This is the force that pulls objects toward each other.
What is gravity?
This term describes making something bigger or smaller while keeping its proportions the same.
What is scale?
DAILY DOUBLE!
In the balloon lab, the stickers represented these objects in the universe.
What are galaxies?
The Big Bang wasn’t an explosion but the rapid expansion of this.
What is space itself?
DAILY DOUBLE!!!
This triggered the cloud to collapse and form the solar system.
What is a shockwave from a nearby exploding star?
The bigger an object, the ___________ its gravitational pull.
What is stronger?
You see a giant statue of an ant at a museum exhibit. This model is an example of something that has been scaled ________.
What is up?
In the gravity well experiment, placing a heavy object in the center caused smaller objects to do this.
What is move toward the heavy object?
Scientists study this to learn about the early universe and confirm the Big Bang theory.
What is light from distant galaxies?
The rocky planets like Earth formed inside this invisible line, close to the Sun.
What is the Rock Line?
Gravity is caused by this property that all objects, even you, have.
What is mass?
These are two real-world examples where scale is used to represent something much larger or smaller (cannot use maps).
What are:
Model Cars
Blueprints
Diagrams of the Solar System
Models of Cells
Building Models
This happened to the distance between the stickers as the balloon was inflated during the expansion model.
What is they increased?
This is the mysterious stuff scientists believe makes up much of the universe but can’t be seen.
What is dark matter?
Water and ices could form in the solar system beyond this extremely cold boundary.
What is the Snow Line?
On the Moon, you would weigh much _______than on Earth because the Moon has __________ gravity.
What are less and weaker?
A model car is labeled with a scale of 1:18. This means the real car is __________ than the model.
What is 18 times larger?
The gravity well lab modeled this phenomenon, showing how planets and moons move in space.
What is orbit?
Scientists believe this force is causing the universe to expand faster and faster.
What is dark energy?
These small objects in the early solar system collided and merged to form larger objects, eventually becoming planets.
What are planetesimals/protoplanets?
This is what would happen to Earth’s atmosphere and oceans if gravity disappeared.
What is they would float away?
To create a scale map of our classroom, we used two steps. First, we calculated the scale factor by dividing the map's size by the real-life size. Then, we did this to find the scaled dimensions of objects for the map.
What is multiplying the real-life dimensions by the scale factor?
When creating our scale map, this number told us how much smaller the map was compared to the real classroom.
What is the scale factor?
