PHYSICAL SCIENCE .
The difference between a physical and chemical change .
What is the change that doesn't change the substance completely change the substance but only the way it looks while a chemical change changes the substance completely and can't be reversed .
The definition of a electromagnet .
What is the magnet that needs a circuit to be powered and can be turned on and off. ELECTRICITY IS MAGNETISM AND MAGNETISM ELECTRICITY.
The definition of a construtive force .
What is a force that slowly builds up the earth's surface after being constructed over the years .
The reason why all bacteria is not harmful .
What is some bacteria that help your body stay healthy while some bacteria can make you sick instead of benefiting you .
The difference between an invertebrate and a vertebrate .
What is a animal that has a backbone (ex : parrot / vertebrate ) and a animal that does not have a backbone (ex : crab / invertebrate ) .
Example of a physical change .
What is breaking glass, melting ice, cutting paper, boiling water, etc ?
The results after you disconnect the circuit to an electromagnet .
What is the magnet loses its magnetism and can no longer work .
An example of a construtive force , and example of a destructive force .
What is disposition and what is weathering and eroison ?
The function of the cytoplasm in BOTH the plant and animal cell .
What is the thing that helps hold all the organleles in place and helps stop them from crashing or bumping into each other ?
Compare the definition of an inherited trait and acquired trait .
What is a trait that is passed down from either parents onto the offspring , while an acquired trait is a trait that is learned from your environment or the things around you .
An example investigation that would provide evidence of a chemical change .
What is the investigation that would provide evidence of a chemical change : one answer / putting a actid tablet in water : new substance produced and bubbles are being formed
The difference between a conductor and insulator .
What is the thing that conducts electricity from a circuit and helps electrons move. While a insulator does not let electrons move and blocks electricity ?
The reason why tree roots get exposed over time .
What is weathering with water and it washes away the soil / sediment over time creating exposed tree roots and carries it into the lake .
Compare beneficial microoganisms and harmful micoroganisms .
What is the bacteria that helps keep the human body healthy and helps with digestion making it a beneficial microoganism. While harmful microoganism harm the human body and makes people sick, (ex: e coil can be harmful while the bateria in yogurt can be helpful ) .
The reason why animals need instincts and learned behaviors .
What is the thing that helps animals survive and stay alive and the thing that helps animals survive or stay safe in that environment .
The things that show us a chemical change has been made
What is a new odor being produced, a color change , a gas being produced , etc ?
The things needed to create a working circuit .
What is a wire (conducts electricity), a battery (powers the circuit) , switch (turns the circuit on and off) , and a light bulb or device (the thing that is being powered by the circuit) ?
The reason why a rock gets smoother over the span of 100 years .
What is the rock getting weathered over time making the surface of the rock become smoother also making it more dull and easier to crack
The reason why yeast used in bread is considered beneficial .
What is the bacteria feeds on sugars and produce carbon dioxide gas which helps the bread rise, it also makes the bread light and fluffy and helps infermnation in food production .
The difference between a seed plant and non seed plant when reproducing .
What is the plant that uses seeds to reproduce ( ex : cones , fruits , flowers ), and the plant that uses spores to reproduce (ex : tiny holes ) .
The reason why temperature changes effect water in all three of the states .
What is different temperatures effect the different states of water ex: if you have a water vapor, condensation might help that turn in a liquid since the heat is descreasing , or if you have a liquid and it turns into a gas, it is because of evaporation, the heat is increased taking all the water into the next state of water .
The reason why a electromagnet is used for MRI machines .
What is the magnet that can be turned on and off making it more useful for a MRI machines instead of it always going like a permanent magnet would .
The reason why a volcanic eruptions can have both construtive and destrutive forces .
What is the volcano erupting destroying everything in its path (ex : homes , landscapes , ecostyems , etc ) making it destrutive, however it is construtive because over time the lava hardens creating new landscapes such as islands or mountains .
The reason why there is a chlorplast and cell wall in the plant cell and not the animal cell .
What is the thing that helps the plant cell produce food since it can not move and find food by its self (chlorplast / helps create photosynies which is sunlight and give the plant the things it need ) . What is the thing that provides extra protection to the cell since it can not move and protect its self from preadators, also provides the cell its strong structure (cell wall) .
Give examples of the vertebrate group and things that they usually have .
What is a fish , aphmibian , reptile , bird , and mammal ? Fish : Skin=scales Birth=soft eggs Breath=gills Blood type=cold Limbs=2 fins and tail , Amphbian : skin=moist birth=soft eggs Breath=gills lungs blood=cold Limbs- 2 arms 2 legs , Reptile : skin=scales birth=leathery eggs breath=lungs Blood type=cold Limbs- 0 or 4 , Birds : skin =feathers birth=hard egg breath=lung blood=warm Limbs- 2 feet 2 wings and beck, and mammal : skin=hair or fur birth=live breath=lungs Bloods type=warm Limbs- 2 arms 2 legs .
