LIVING THINGS
What type of animal are humans?
Humans are mammals.
What do we call it when pollen moves from one flower to another?
This is called pollination.
What part of your eye helps you see clearly?
The lens focuses light so you can see clearly.
When a roller coaster goes up a hill, what kind of energy does it get?
Gravitional Energy/Potential Energy
What is the closest star to Earth?
The sun
Is a shark a fish or a mammal? How do you know?
A shark is a fish.
Why do plants need bees?
Plants need bees because bees carry pollen from one flower to another, which lets the plants make seeds and reproduce.
Why do volcanoes form near the edges of tectonic plates?
Volcanoes form near tectonic plate edges because that's where plates can pull apart, push together, or slide past each other, which creates cracks that let melted rock (magma) rise to the surface.
Why is wind a renewable energy source, but coal is not?
Because you can never run out of wind, but you can run out of coal.
What do we call the planets after Mars?
The outer planets
A frog can breathe through its skin. Why can frogs do this, but dogs and lizards cannot?
Frogs are amphibians, and amphibian skin is thin and moist, which lets oxygen pass through it directly into the blood. Dogs and lizards have thicker, drier skin that doesn't allow this, so they rely only on their lungs.
A tomato grows from a flower and has seeds inside. Is a tomato a fruit or a vegetable? Explain.
A tomato is a fruit, because in science, a fruit is the part of the plant that grows from a flower and holds the seeds. People often call it a vegetable in cooking, but botanically it's a fruit.
The crust is the thinnest layer of the Earth. Why can it still cause big earthquakes?
When these plates push, pull, or grind against each other, the built-up pressure releases suddenly, which causes powerful earthquakes.
What type of reaction is putting baking soda and white vinegar?
A chemical reaction
Jupiter is the biggest planet. Is it made of rock, like Earth, or something else? Explain.
Jupiter is made of gas
A bat and a bird can both fly. Name two ways you could tell them apart.
birds have feathers and beaks, while bats have fur and teeth. Birds also lay eggs, while bats give birth to live babies and nurse them like other mammals.
A carrot grows under the ground. Is a carrot a fruit? Why or why not?
A carrot is not a fruit because it does not have seeds
Think about going from the crust to the center of the Earth. Name the layers in order
From the crust down to the center: crust (thin, rocky, where we live), mantle (thick layer of hot, slowly moving rock), outer core (liquid metal), and inner core (solid metal due to intense pressure)
Why does a gas spread out to fill its whole container, but a solid keeps its shape?
A gas spreads out because its particles move freely and quickly in all directions, filling whatever space they're in. A solid keeps its shape because its particles are tightly packed and barely move, holding a fixed structure.
Why do we have day and night on Earth?
Because earth spins on a axis
An animal lays eggs and has a backbone. When it is a baby, it breathes with gills. When it grows up, it breathes with lungs. What kind of animal is this? Explain your answer.
This is an amphibian.
Some flowers are bright and smell nice. Other flowers are small and plain. Why do you think some flowers are bright and smelly?
Bright colors and nice smells attract bees and other helpers. This helps the flower get pollen moved to other flowers.
The outer core is liquid. The inner core is even hotter, but it is solid. Why?
The inner core is solid even though it's hotter because of extremely high pressure. All the weight of the Earth pressing down keeps the metal squeezed so tightly that it can't move like a liquid, even at very high temperatures.
One ball sits on a high shelf. Another ball rolls across the floor. Which ball has more potential energy?
The ball on the high shelf
Saturn's rings are made of ice and rock, not one solid piece. Why don't the rings fall into the planet?
There is not enough gravitional energy to make them fall meaning they orbit around the planet.
