Identify 2 animals present during the Ice Age that are still around today
Sloths and lions
Dinosaurs weren't the only things running around during the Cretaceous Period. Name two other creatures that were present during that time
Worms and other bugs, prehistoric turtles, and small mammals
What are 2 key differences between Earth and all other planets in our Solar System?

Identify 2 ways ancient sloths are different from modern-day sloths

The Kuiper Belt
A skeleton of a mammoth was found in a backyard in which U.S. state?

What is the difference between a food chain and a food web?

Why were small shrubs, but NOT large trees, present during the Ice Age?
Large trees require a lot of water, but small shrubs don't. Since most of the water was frozen during the Ice Age, the trees weren't able to grow.
Identify 2 possible effects of a large asteroid hitting Mexico and the surrounding Gulf
The impact could cause a tsunami, forest fires, and earthquakes, and might trigger volcanic eruptions. It would kill everything in the impact zone and would produce a great deal of dust and debris
Why is Pluto no longer considered a planet?
It is too small, and thus have enough gravitational force to clear the area around its orbit

Identify one way you can reduce your negative impact on the Earth
Results may vary
Are mammoths or mastodons the ancestors of the modern-day elephant? What evidence do we have?
Mammoths- their molars are flat and suited for grazing, just like elephants
How could an asteroid hitting an area of Mexico have killed off dinosaurs all over the world?
It raised a massive amount of dust/ash that lingered in the atmosphere for years, blocking the Sun and killing off plant life. This caused herbivores to die off, which in turn caused carnivores to die off
Why can't astronauts spit when they brush their teeth on the International Space Station?
Because the water/spit will float away in globs, since the lack of gravity makes things float, and water in space tends to stick to itself and to other objects
Name 2 of the 3 kinds of teeth all mammals have
Vanines, molars, incisors
What is the function of a circuit?
It connects a power source to something that needs power, allowing electricity to flow between them
How did animals get from the Americas into Asia and Africa during the Ice Age?
They used a frozen strip of land known as the Bering Strait, which connected Alaska to northern Asia
What did the animals that survived the mass extinction event have in common? How did that help them survive?
They were all small and omnivorous, so they didn't require much food to survive and could find another source of food if one source died off
Name one food/drink item that is banned on the ISS and why
bread/chips- crumbs go everywhere and can clog the machines; pop/soda- carbonation causes wet burps
What kind of rabbit can be found in desert, tundra, AND forest regions?
Cottontails
Identify one similarity and one difference between grazers and browsers
Both grazers and browsers are herbivores; grazers have flat molars and eat mainly grasses, while browsers have ridged molars and eat mainly bark and branches
