What are the 6 competencies for teachers of science at any grade?
- Planning inquiry based science programs
- Guiding and facilitating student learning
- Assessing teaching and student learning
- Developing environments that are enabling
- Creating communities of science learners
- Contributing to the planning ad development of the school science program
What is cooperative learning?
Structured groups that combine positive interdependence with individual accountability to develop social skills as well as content knowledge through group interactions and processing
What is collaborative learning?
Loosely structured groups that allow students to learn from and with each other
What type of learning is working together to solve complex, open-ended problems?
Problem-based learning
Define contextual learning
Authentic real-life situation
What is an anemometer?
Measures wind speed
What type of assessment is Classroom assessment technique (CAT)?
Brief prompts used to gather information about student understanding or perception at the end of a class or lesson
What type of assessment is conceptual ?
Comprehension and application of content in written or oral form
What type of assessment is concept map?
Graphic rep, of concepts and how they relate to each other
What type of assessment is performance?
Demonstration of ability or knowledge
What type of assessment is project-based / problem-based learning?
Investigation and response to engaging, authentic, and complex question, problem, or challenge
Define pressure
Amount of force applied to master affects volume
Define density
The ratio of mass to volume that depends on the type of matter
What is the composition of the heterogenous mixture of Emulsion?
Liquid and liquid
What is the composition of the heterogenous mixture of Suspension?
Liquid and solid
What is the composition of the heterogenous mixture of Aerosol?
Gas and liquid
What is the composition of the heterogenous mixture of gas and solid ?
Smoke
Heterogenous v Homogenous
Homo: solutions in which the individual components are uniformly distributed throughout the mixture
Ex:air, water, vinegar, steel, cup of coffee, plain chocolate, sugar water, olive oil
Hetero: contains liquid(s), solid(s), and gas(es) in which the components are not uniform or have localized regions with different properties
Ex: Cereal in milk, pizza, blood, gravel, ice in soda, salad dressing, mixed nuts, soil
Define molecules
Two or more atoms that combine chemically to form
Define compounds
Molecules that can be elements with the same kind of atoms
What is Newton’s first law of motion?
An object at rest tends to stay at rest
An object in motions tends to stay in motion at a constant speed in a straight line or path
What is Newtons 2nd law of motion?
When a net force acts on an object, the object accelerates
What is Newtons 3rd law of motion?
For every action, there is an equal and opposite reaction
How do volcanoes form?
When 2 plates separate enough for magma to release through the crust usually in a violent explosion
What is chemical weathering?
Changes to the atomic structure of matter through hydrolysis, oxidation, reduction, hard action, carbonation, and solution
What is physical weathering?
It occurs when minerals and rocks are broken down by mechanical methods such as abrasion, crystallization, wetting and drying, or pressure release
What is biological weathering?
This occurs when an organism psychical or chemical agents disintegrate rocks or minerals.
What are igneous rocks ?
-Found under or above ground.
-These are the result of the lava cooling above ground
-Ex: Granite and Obsidian
What are sedimentary rocks?
Results from wind or water breaking or wearing down small pieces of Earth that often settle to the bottom of rivers, lakes, and oceans
What are metamorphoic rocks?
Rocks changing or morphine into other kids of rocks.
Igneous or sedimentary rocks heated under tons of pressure change into this
What are the layers of earths atmosphere?
The Silly Monkeys Twirled Endlessly
Troposphere - weather occurs
Stratosphere - protective ozone
Mesosphere - space debris durns u at this level creating shooting stars
Thermosphere - temperature rises as thin air absorbs solar radiation
Exosphere - Furthest layer
