Physical Science: Conservation of Matter
Heat energy transfers from hot to cold? or from cold to hot?
What is "hot to cold"?
Magnets have two poles called the North pole and the South pole. If you face two North pole sides to each other, will the magnets repel or attract?
Repel
The movement of sediment from one place to another is called________.
What is erosion?
True or False
Fossils are being formed today. Explain your answer.
True. Fossils are always being formed if the conditions are right. hundreds, thousands, millions of years from now, they will tell the story of our lifetime and what the environment was like.
Anything that has mass(weight) and takes up space (a solid, liquid, or gas) is considered this.
Matter
Within an electrical circuit, what would cause a lightbulb not to turn on?
No pathway, dead battery, incomplete circuit, not having pathways that are conducting, etc.
Opposite poles of a magnet will _____________.
What is attract?
Name a type of weathering.
Wind, Ice wedging, or root wedging
What can the teeth of a fossil tell us about that particular species?
Whether it is an herbivore(flat teeth) or a carnivore (pointy teeth)
Adding baking soda to vinegar creates bubbles. When you see these bubbles, is a chemical change or a physical change happening?
Chemical change
Name a type of clean energy
Wind, water or solar energy
List two examples of items that will conduct electricity.
What are iron, salt water, copper, etc.?
What is the final resting place of debris or sediment called?
Deposition
Scientists found whale fossils in the desert. What does this tell us about the environment?
It was once covered in water"?
Mrs. Wichert put ice cubes in her glass of tea and left the glass on the table in the sun. When she returned 15 minutes later, the ice cubes were gone. Did a chemical or physical change happen?
Physical change
The breaking of rocks by water, ice, or plants is known as ______________.
What is weathering?
A frog lives in a marshy wetland and lays its eggs in a shallow pool of water. Give an example of something that would change the ecosystem of the frog.
Trees cut down so sunlight dries out the marsh, etc.
Explain how the water cycle works using the scientific words that we learned.
What is Precipitation, Collection, Evaporation, and Condensation?
Rubbing your hands together creates this type of energy.
What is thermal (heat) energy?
Explain how ice wedging works. What is this an example of?
Rain gets into the cracks of a mountain. The water freezes and when water freezes, it expands. This expansion puts pressure on the rocks and eventually cracks them. This is an example of weathering.
Name two types of volcanoes and tell which type of lava is in each one.
Cone and Shield
Thick lava in Cone
Thin lava in Shield
True or false: The higher the location of a fossil in a quarry, the younger the age of the fossil.
True- We can estimate the age of fossils by the number of rock layers above it.
