Why We're Learning It (TEKS): 5.10 A-C
The student is expected to...
compare the structures and functions of different species
differentiate between inherited traits and learned behaviors
describe the differences between complete and incomplete metamorphosis of insects

Late Homework Procedure
1. Your student has Science homework on Thursdays.
2. It should be written in his/her planner.
3. It is due on Friday unless otherwise noted.
4. If your student does not have it the day it is due, he/she can bring it to the Science teacher at 7:30 the next morning, completed, and avoid after school detention. Otherwise, your student will have to serve the detention (3:30-4:30) to do the work. (This will fall on Monday unless the work was due on a day other than Friday.)
5. If work is not turned in and detention is not served, your student will receive a discipline referral.
STAAR Review Sites
Adaptations, Traits, & Behaviors
- physical adaptations
- behavioral adaptations
- inherited trait
- learned behavior
- life cycle
- Plants and animals change their structures and behaviors over time to help them survive in their environment.
- Inherited traits are characteristics that are passed down from a parent to an offspring. Some examples include: beak shape and size, fur color, leaf shape, eye color, etc.
- Learned behaviors are developed by animals after being taught, such as reading a book, doing a trick, riding a bicycle, etc.
- Butterflies, moths, and some other species undergo Complete Metamorphosis ( a nearly unrecognizable body change). The four stages of Complete Metamorphosis are Egg, Larva, Pupa, Adult.
- Some insects do not undergo such a drastic change in their metamorphosis. The three stages of Incomplete Metamorphosis are Egg, Nymph, Adult.

The Sun, Earth, & Moon
- day/night cycle
- The Earth's rotation on its axis causes the day/night cycle and the "apparent" movement of the Sun across the sky.
- There are regular and repeated patterns to the cycles of movement between the Sun, Earth, & Moon (i.e., shadows, seasons, day/night, moon phases, etc.)
- The Sun, Earth, and Moon has different physical features.
Weather & Climate
- high pressure
- low pressure
- Weather is the current atmospheric conditions at a certain time and place.
- Climate is a 30+ year average of weather data.
The Water Cycle
- ground water
- The Sun provides the energy to move water through the water cycle.
- Some models show the water cycle better than others.
Alternative Energy Sources
Important Vocabulary: Important Concepts:
alternative hydroelectric * These are alternative energy sources to fossil fuels.
renewable biomass * They are renewable sources of energy.
Fossil and Fossil Fuel Formation
fossils stored energy
pressure carbon dioxide
- Fossils are the evidence of past living things.
- They reveal what the climate and ecosystem of an area were millions of years ago.
- Fossil Fuels formed the same way that fossils did.
- Fossil Fuels are trapped, stored energy.
- They are non-renewable and create pollution and CO2 when burned.
Changes to Earth's Surface
weathering wedging glacier physical chemical
erosion sediment landforms deltas canyons
deposition dunes fossils compaction cementation pressure
- The surface of the Earth is always changing. Some processes build up new land forms, while some tear them down, but the changes occur in a continuous cycle of weathering, erosion, and deposition.
- Weathering is the BREAKING of rock into smaller pieces.
- Erosion is the MOVEMENT of rock and sediment from one place to another.
- Deposition if the DROPPING of rock and sediment in a new location.
- Wind, water, and ice are the AGENTS of weathering, erosion, and deposition.
Important Vocabulary for Electricity Important understandings about Electricity
current * Electricity can only flow in a complete, closed circuit.
conductor * Electricity is not useful until it is converted into another form,
battery such as light, heat, or sound energy.
switch * All parts of an electric circuit must have an "in" and an "out"
fuse for the electricity to flow.
convert * Ways to "open" a circuit (and therefore stop the flow of
electricity) include flipping a switch, breaking a fuse, tripping a breaker, or burning out a resistor.
Important Vocabulary for Light Energy
Important Understandings about Light Energy
- Light travels in a straight line until it strikes an object.
- When it strikes an object (or a medium), it can be absorbed, transmitted, reflected, or refracted.
- A key synonym for "reflect" is "bounce".
- A key synonym for "refract" is "bend".

Important Vocabulary for the Matter Unit:
- Relative Density
- Physical state
- Boiling Point
- Freezing Point
- Triple Beam Balance
- Graduated Cylinder
- Units for Measuring
- Cubic Centimeter
- Celsius Thermometer

- When watching a Crash Course Science video, be sure to go into settings ---> speed and slow it down to .75. The narrator speaks REALLY fast and this should help you hear and process what she says.
- Remember that you can stop and rewind as needed to make sure you comprehend. :-)
