States of Matter
What state of matter has no definite volume and fills the shape?
Gas
What is an example of a mixture and a solution?
Mixture-Oil and water, 2 or more items
Solution-salt water, lemonade, sugar water
Give one example of a physical and chemical change.
Physical change can reverse items
chemical-becomes new substance
What is an adaptation?
a change in behavior, structure, or function that helps an organism survive and thrive in its environment
How is mass measured?
With a balance scale
What are the 3 states of matter and give an example of each state.
Solid, Liquid, Gas
What method can you use to separate iron filings from wood chips?
Magnetic separation
Name two examples of what creates physical change.
Melting, cutting, folding, smashing, breaking, evaporating
What is an inherited trait?
physical or biological characteristics passed from parents to offspring through genes during reproduction
What would a balance scale look like to measure mass of a rock?
Balanced-level
Explain the molecules in each state of matter.
Liquid-a little space between, Gas-spread far apart
Solid-tightly compact
What do you use to separate items with different densities in water?
Floatation
What type of change can often be reversed and give 1 example.
Physical Change-salt water, ice, sugar water
Name 3 physical adaptations
ears, claws, webbed feet-etc.
What are the 3 climate zones and what type of weather can be found in each?
Tropical-hot and humid or dry
Temperate-Mild weather with seasons
Polar-Cold most of year
How do you measure the volume of a solid and a liquid?
Solid-Measuring tape or ruler-measure and multiply length, width and height.
Liquid- beaker, measuring spoons-cups, dropper
Name 3 methods to separate mixtures and explain each.
Floatation-densities
Filtration-for small items like dust
Sedimentation-sand goes to bottom of water
Magnetic
Sieving-different sized items
What are 4 examples of chemical change?
burning, decaying, rusting, cooking, baking, fireworks
Name 3 behavioral adaptations
camouflage, migration, hunting in packs, mimicry
Name 3 cloud types and type of weather each brings.
Cirrus- Fair but could change in 48 hours
Cumulus-sunny and dry
Stratus-light rain
Cumulonimbus- Thunderstorms, hail, heavy rains
Which state has the most energy and why?
Gas-because the molecules have are spread apart and can move around more.
What do we call when a solid becomes or cause to become incorporated into a liquid so as to form a solution, and what can you do to make it blend quicker?
Dissolve-mix, stir and heat
Is salt water a physical or chemical change and why?
Physical-because the water can be evaporated and the salt is left behind (reversed)
What are 2 adaptations for the desert and for the polar environments.
Desert-
What a the 3 rock types and give a characteristic of each.
Sedimentary-soft, layered, fossils
Metamorphic-Have pieces of all rock types cemented together from heat and pressure deep in Earth
Igneous- Formed from cooled magma
