Compositions 1-4 Flashcards
ADULT TOADS
Although toads can lay thousands of eggs, in truth only a small number of those eggs will blossom into tadpoles or full toads -predators will menace these babies every step of their developmenT
MICROSCOPE
A microscope is an optical instrument used for viewing very small object, typically magnified several hundred times. A higher power objective lens has greater magnification than a lower objective lens. From this analogy, fewer cells will be seen with the high power lens but in greater detail.
CONSTRUCTIVIST THEORY
supports student-centered instruction. student is an active participant. the student will be interacting with peers in small, manageable, cooperative groups. engage in higher thinking skills. the student will be analyzing(breaking down information into parts) synthesizing(creating something new based on previous learning) and evaluating and judging information.
PROCESSES OF SCIENTIFIC INQUIRY
involve asking scientific questions, formulating a testable hypothesis, selecting appropriate equipment and technology to gather information related to the hypothesis, making observations and collecting data, organizing, analyzing and evaluating data to find trend and patterns, communicating and defending a valid conclusion
CHECKLISTS
used for formative (ongoing) assessment to monitor students’ behavior and progress towards reaching stated goals. it indicates if a student can accomplish the listed objectives does not include the quality of the performance
SCIENTIFIC METHOD
based on gathering observable and measurable evidence
LABORATORY EXPERIMENTS
the best way to minimize possible inconsistencies and reduce bias is to have the same group perform several trials of an experiment and average the values together to get a more accurate value of the measurement
MATERIAL SAFETY DATA SHEETS (MSDS)
should always be followed meticulously. They are shipped with chemicals and describe proper storage, use, handling, mantenance, and disposal. Up-to-date MSDS should be kept in a central location available for all teachers using materials.
VOLUME
the measure of the amount of space an object takes up-how big an object is in all three directions.
AREA
the measure of surface room- how big something is in two directions
LENGTH
the distance from one point to another as measured by a ruler
MASS AND WEIGHT
Mass is a measure of the amount of matter in an object
Weight is a measure of the pull of gravity on an object
on Earth mass and weight are very similar. Use a balance to measure mass and a spring scale to measure the weight
MICROSCOPE
A microscope is an optical instrument used for viewing very small object, typically magnified several hundred times. A higher power objective lens has greater magnification than a lower objective lens. From this analogy, fewer cells will be seen with the high power lens but in greater detail.
RECYCLING
- slows down rate of burn garbage or put in landfills
- fewer landfills more space to farm, live in, and work
- reduce need to consume fresh natural resources for new products
- saves energy and reduces pollution
- help slow down global climate change, caused by burning fossil fuels like oil and gas
NATURAL RESOURCES
- recycling helps save this resources.
- if old and used materials are not recycled, the new products are made from extracting fresh raw materials from beneath the earth through mining and extraction.
- recycling helps in conserving important raw materials and protects naturals habitats for the future
- conserving natural resources such as wood, water and minerals ensures its optimum use.
GARBAGE
- burning trash emits harmful gases that pollute the air and could contribute to global warming
- the introduction of harmful gases in the atmosphere is unsafe and unhealthy
- a disadvantage of burning garbage
ATMOSPHERIC PRESSURE
the higher up a mountain the thinner the atmosphere; the less the atmosphere, the less pressure on the item, so the faster a egg boils. this means to cook it and get the same hardness, the egg should be cooked for a shorter time.
LAND DEGRADATION
will lead to not enough food being produced
-biotechnology can be used to protect crops, create better fertilizers, and modify foods to increase quantity.
AGRICULTURAL BIOTECHNOLOGY
- a range of tools, including traditional breeding techniques, that alter living organisms, or parts of organisms, to make or modify products; improve plants or animals; or develop microorganisms for specific agricultural uses
- includes the tools of genetic engineering
- provides farmers with tools that can make production cheaper and manageable.
- crop production options can help countries keep pace with demands for food while reducing production costs
TOXINS
- an antigenic poison or venom of plant or animal origin
- can interfere with nerve transmission and the micro-molecular cellular structure of the body
- can lead to malfunction of cell division and growth and healthy tissue formation
PESTICIDES
- a substance used for destroying insects or other organisms harmful to cultivate plants or to animals
- might interfere with DNA replication and gene production
AKA-BANE VIRUS
insect-transmitted virus that passes through the placenta and infects the fetus causing congenital abnormalities (blindness, difficulty in walking) of the central nervous systems in ruminants
HIGH LEVELS OF XRAY
exposure of the fetus to very high levels of x-rays can lead to serious abnormalities like small heads (microcephaly) with associated retardation, bone defects in the skull, spinal and eye defects. it partially destroys the genetic material that acts as a blueprint for normal cell development
BAROMETER
- the instrument used for measuring atmospheric pressure; used especially in forecasting weather and determining altitude
- uses its atmospheric pressure readings to determine altitude and more accurately determine how quickly you’re moving through and area in a vehicle.
- uses the principle that air gets thinner the farther up you go. because of the information it provides, barometers have become increasingly useful for smartphones navigation apps to help assist the GPS in them in determining locations
ACCELEROMETER
- motion sensor
- used to pinpoint an earthquakes epicenter, and therefore speed up aid response in the event of a catastrophic earthquake
ECOSYSTEM
a biological community of interacting organisms and their physical environment
PREDATORS
an animal that naturally preys on others
PREY
an animal that is hunted and killed by another for food
DECOMPOSER
- they breakdown dead materials
- fungi and bacteria
- responsible for breaking down the complex organic compounds into simple nutrients.
- if let out of the ecosystem, plants will not get essential nutrients and dead matter and waste will pile up
HERBIVORES
animals adapted to eat plants
MECHANICAL ENERGY
- the sum of kinetic and potential energy
- in other words, it is energy in an object due to its motion or position, or both
ELECTRICAL ENERGY
- used to move charged particles through wire from a power plant to our homes
- energy of moving electrons
SOUND ENERGY
- caused by an objects vibrations
- a form of energy associated with the vibration of matter
FORCE
strength or energy as an attribute of physical action or movement
LABORATORY
- a room or building equipped for scientific experiments, research, or teaching, for the manufacture of drugs or chemicals
- more variables can be monitored and controlled with greater precision than in the natural world and observations detected more readily
MODELS
used to represent systems and their interactions- such as inputs, processes and outputs- and energy, matter, and information flows within systems
-can be used to predict the behavior of a system
OBSERVED PATTERNS
- prompts questions about relationships and causes underlying them.
- similarities and differences in patterns can be used to sort, classify, communicate and analyze simple rates of change for natural phenomena and designed products
SYSTEM
-an organized group of related objects or components;
METAMORPHIC ROCK FORMATION
rock that was once one form of rock but has changed to another under influence of heat, pressure, or some other agent without passing through a liquid phase
