What is a physical change that doesn't change substances and a chemical change, changes substances.

What is static electricity? What is human-harnessed electricity?
What is static electricity is when electric charge builds up on something, like when you rub a balloon on your hair. Human-harnessed electricity is the kind we use in homes and buildings, coming from power plants and wires.

What are two examples of constructive processes and two examples of destructive processes that shape Earth's surface?
What is volcanic eruptions and deposition by rivers. In addition, erosion and earthquakes.
100
What is a microorganism?
What is a microorganism is a tiny living organism that can only be seen under a microscope. Examples include bacteria, fungi, protozoa, and viruses.

What is an instinct? What is a learned behavior?
What is an instinct is a behavior an animal is born with. It happens automatically and doesn’t need to be taught.Example: A turtle going to the ocean right after hatching. A learned behavior is something an animal learns by watching, practicing, or being taught.
Example: A dog learning to sit when given a treat.

How can filtration and evaporation be used to separate a mixture of salt and water?
What is filtration cannot separate dissolved salt from water. Evaporation can be used by heating the saltwater until the water evaporates, leaving the salt behind.
200
How are static electricity and human-harnessed electricity different?
What is the difference between static electricity is caused by a build of up friction causing static electricity. Human-Harnessed electricity is gained from power plants.

How does erosion differ from deposition in shaping Earth's surface?
What is erosion wears down things meanwhile deposition builds up.

What is the function of the cell membrane?
What is the cell membrane controls what enters and exits the cell. It acts like a gatekeeper.
200
Question: What is one way that an instinct is different from a learned behavior? What is one way they are similar?
What is different: Instincts happen without teaching, but learned behaviors require training or experience. Similar: Both are behavior patterns that help animals survive and adapt to their environment.

Explain why some substances dissolve in water while others do not. Use scientific reasoning to support your answer.
What is substances dissolve in water based on their molecular structure and polarity. Water is a polar molecule, meaning it dissolves other polar substances (like salt and sugar) but does not dissolve nonpolar substances (like oil).

You tested a metal spoon and a wooden spoon in a circuit. The light bulb turned on with the metal spoon but not the wooden one. Why?
What is the metal spoon is a conductor, so it lets electricity flow. The wooden spoon is an insulator, so it stops electricity.

Given a specific landform, such as a delta or a sand dune, analyze the processes that contributed to its formation. What evidence supports whether it was created by constructive or destructive forces?
What is deltas are formed at the mouth of the river and is made by constructive force which means a deltas is made by deposition, and sediment layers and the change in the river channels are proof.

Explain how the structure of a plant cell supports its function in a plant's survival.
What is the cell wall provides rigid structure for support and helps the plant stand upright. Chloroplasts allow the plant to perform photosynthesis, creating energy. The large central vacuole (not explicitly in the standard, but often present) stores water and helps maintain pressure inside the cell.

Create an interview with a zookeeper, wildlife expert, or pet owner. Include at least 3 questions about animal instincts and 3 about learned behaviors. Afterward, explain how the answers help you compare and contrast the two types of behavior.
What is Instincts:What is a behavior your animal does without being taught? Are all animals of that species born with the same behavior? How does that behavior help the animal survive?
Learned Behaviors: What is something you taught your animal to do?How long did it take the animal to learn it? What tools or techniques helped with training?

Develop a step-by-step procedure for separating a mixture containing sand, salt, and iron filings. Justify why you chose each separation method and how it demonstrates physical changes.
What is Step 1: Use a magnet to remove the iron filings (magnetism). Step 2: Add water to the sand and salt mixture. The salt will dissolve while the sand remains. Step 3: Use filtration to separate the sand from the saltwater solution.Step 4: Evaporate the water to retrieve the salt.

Plan an experiment to test if different objects are conductors or insulators. What materials will you need? What steps will you take?
What is, 1:Gather materials: battery, wires, light bulb, different objects (penny, rubber band, paperclip, plastic spoon). 2:Connect the circuit with the battery, wires, and light bulb. 3:Test each object by placing it in the circuit. 4:Observe if the light bulb turns on (conductor) or stays off (insulator). 5:Record the results and classify each material.

Construct an argument using scientific evidence to explain how both constructive and destructive processes have interacted to shape a well-known surface feature, such as the Grand Canyon or a volcanic island. How do these processes continue to shape the landscape over time?
What is constructive and destructive processes have been used to make things like the Grand Canyon or many other things the Grand Canyon was made by destructive processes and you can tell by just looking at it because you can see that dirt, rocks, and sediments have been eroded and weathered. These processes never stop continuing to shape the landscape over time because the weather never stops.

Given two unlabeled diagrams—one of a plant cell and one of an animal cell—develop a model to correctly label and distinguish them using evidence.
What is look for the cell wall and chloroplasts to identify the plant cell. If these are absent, and the shape is more rounded or irregular, it's likely an animal cell. Label the membrane, cytoplasm, and nucleus in both. For the plant cell, also label cell wall and chloroplasts.

What is an inherited trait? What is an acquired trait?
What is an inherited trait is a physical characteristic passed down from parents to their offspring through genes. Example: Eye color, hair type, dimples. An acquired trait is a physical characteristic a person develops over time due to environment, experience, or lifestyle. Example: Scars, dyed hair, muscles from exercise.

Create a model or simulation to show how mixtures can be physically separated using different techniques like filtration, magnetism, and evaporation. How could this knowledge be useful in environmental science or industry?
What is Use different materials (iron filings, sand, salt, water) to create a demonstration of separation techniques. Applying in environmental science:Cleaning polluted water by filtering out impurities. Applying in industry: Separating useful materials in mining and recycling.

Construct a well-supported argument using experimental data to explain why electromagnets are used in MRI machines instead of permanent magnets.
What is MRI machines use electromagnets to able to turn on and off to able to be used and not always staying on, and therefore a permanent magnet cannot be used in a MRI machine because it doesn't turn off and on.

Given a specific landform, such as a delta or a sand dune, analyze the processes that contributed to its formation. What evidence supports whether it was created by constructive or destructive forces?
What is deltas are formed at the mouth of the river and is made by constructive force which means a deltas is made by deposition, and sediment layers and the change in the river channels are proof.

Design and create a 3D model or digital animation comparing the structures and functions of plant and animal cells. Explain the significance of each labeled part.
What is Nucleus: Controls cell activities (both).Cell membrane: Regulates materials entering/exiting (both). Cytoplasm: Holds organelles and supports reactions (both).Cell wall: Adds support and structure (plant only).Chloroplasts: Site of photosynthesis (plant only). In a video or model, explain how each part helps the cell survive and how plant-specific parts support photosynthesis and structure.
