Define Chemical and Physical changes
What is a Chemical change crates a new substances with different properties and a physical change is only a change in for or state of the subtsance
Name a device that used Electromagnetism
What is a doorbell and an electro motor because these devices use electricity to make a temporary magnet
What is a constructive process that forms new land?
What is volcano euruption because it builds up the Earth's surface when lava flows from a vocano and cools down it hardens into a rock and forms new lands like island and mountains.
What is the basic unit of life?
What is the cell because the cell is the smallest unit that can carry out all the processes needed for life
What are inherited traits
What is inherited traits are traits passed down from their parents to the offspring like for an example, eye color, hair color, and hair type
Predict what happens when you mix vinegar and baking soda
What is it bubbles and fizzes making it a Chemical change?
Descrip what happens when a circuit is open
What is it doesn't work because the electricity cannot flow so devices that uses the circuit wont work
Compare a constructive and destructive processes and give a example of each
What is a constructive process builds up land like a volcano forming a mountain or island and a destructive process breaks down land like erosion carrying away a hill side
Compare plant cells and animal cells, what are two differences
What is plant cells have a cell wall that is stiff that gives them their rectangle shape and helps them protect them and chloroplasts helps them make their own food with photosynthesis from sunlight and animals get their food from by just eating it not making it
What is one difference between inherited traits and learned behaviors?
What is inherited traits come from your parents like hair type, skin color , and eye color while a learned behaviour is something you pick from your peers after you are born like learning to ride a bike or talk
Make a claim about a substance changing and support your claim with evidence
What is burning toast is a chemical change because of a change in color, smell, odor, and it is irreversible.
How can magnetism be used to generate electricity
What is since magnetism is used to generate electricity in devices like generators when the conductor like for example a copper wire it moves through a magnetic field and the motion causes electrons to move making an electric current
Explain how a river can be both a constructive and a deconstructive force
A river can be destructive when it erodes the land and constructive when it deposits sediment because when water is flowing it erodes the banks and carries away soil which is a destructive process and when the water is slowing down its flow it drops the sediments is was carrying and the deposition can build things like deltas or new land making is also a constructive process
Why are some microorganisms helpful and others harmful
What is helpful organisms do good things like helping us digest food and make food while harmful ones cause diseases like yeast is used to help bread rise
Why do some animals species look different even though they have the same inherited traits
What is they can have small differences in their genes and the environment can also affect how traits show up because the genes are also mixed ina different way
Use evidence to argue that condensation is a physical change and not chemical. Explain your answer.
What is the water vapor turns back into liquid and no new substance is formed.
Predict how adding more batteries in a circuit will make the bulb more brighter
What is adding more batteries in a circuit will increase the voltage which will make the current flow faster making it increase the brightness of the bulb because the number of batteries the more energy it gets to get brighter
draw an investigation show how wind cause erosion and how it changes land over time
What is you can use a tray of sand and a fan to show how it changes the surface because the fan could act as wind making it erode the sand making it show flattened areas or new patterns
if you were looking at a cell under a microscope how would you tell if it was a plant cells or animal cell
What is if I looked under microscope I would look for a cell wall and chloroplasts for a plant cell and if it has both it would be a plant cell that being the only two parts a animal cell doesn't have
A student went outside to classify common plants found in her backyard. The student came across a tree and looked down. Near the bottom of the tree, there was a low growing plant. She picked up the damp plant and it peeled off from the tree and noticed there was just fuzz underneath the plant.
Which plant could the low-growing plant be classified with
What is the low growing plant can be classified with algae because they both do not produce seeds nor do they have roots, leaves, and stems
Compare and contrast the effects of physical change on different materials like plastic and metal
What is Heat bends plastic more than metal and they both only change shape but keep the substance the same.
Explain how electro magnets can help move more heavy objects than other magnets
What is Magnet slike electromagnets are used in junkyard to lift old metals like old cars and other heavy medals because when using an electromagnet when you turn it on it can become stronger And it can be controlled
make a plan to protect a coastel like town from both destructive and constructive natural processes (explain)
what is you can build sea walls and plant dunegrasses to stop the erosion and guide sediment with barriers to help form a protective sandbar
If you could design a cell that works like both a plant and animal cell what parts would you include and why would you include it
What is I would include chloroplasts to make food and parts to help it move like cilia or flagella
Create a way to classify animals based on its inherited traits like its skin and how they move
What is to classify animals I could first look at their body covering like if it has fur its a mammal, feathers a bird, scales either a fish or reptile the group them based off there traits I would be able to group them
