Chemical and physical
what is a physical and chemical?
a physical change is like changing the way something looks or feels without making it into something new, like tearing a piece of paper or melting ice. A chemical change is when something transforms into a new substance altogether.
What is an example of static electricity?
what is A common example of static electricity is experiencing a small shock when touching a doorknob after walking across a carpet
What are two examples of constructive forces that build up landforms?
two examples of constructive forces that build up landforms are volcanic eruptions and deposition of sedimen.
What is a cell?
what is the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm.
What is the definition of an instinct?
what is An instinct is a behavior that an animal is born with and does not need to learn.
How is melting ice different from burning?
what is Melting ice is a physical change where a solid transforms into a liquid, while burning is a chemical change that involves a reaction with oxygen, creating new substances and releasing energy as heat and light.
Explain how a battery is used to make a lightbulb turn on?
what is A battery makes a lightbulb turn on by providing electrical energy that flows through a circuit, including the lightbulb.
Describe how weathering and erosion work together to change a mountain over time.
what is Weathering and erosion work in tandem to reshape mountains over time. Weathering breaks down mountain rock into smaller pieces, while erosion then transports these fragments away, ultimately leading to a reduction in the mountain's height and changes in its shape.
How do cells help the human body?
What Cells are the tiny building blocks that make up everything in your body, including your skin, bones, and organs. They work together to help your body grow, stay healthy, and function properly. Just like bricks in a wall, they provide structure, take in nutrients, and make energy.
What is the definition of a learned behavior?
what is A learned behavior is a behavior that an animal learns through experience or observation.
A student mixes baking soda and vinegar and observes bubbles forming. Is this a physical or chemical change and why?
what is The mixing of baking soda and vinegar to produce bubbles is a chemical change. This is because the reaction results in the formation of a new substance, carbon dioxide gas, as evidenced by the bubbles, and a change in the mixture's properties.
How can you use a magnet to create an electromagnet?
what is A permanent magnet can be used to enhance the magnetic field of an electromagnet by making it a core for the electromagnet?
How do both constructive and destructive forces work together to shape the Earth's surface?
what is Constructive and destructive forces work together to shape the Earth's surface through a continuous cycle of building up and breaking down landforms.
What's the difference between a plant cell and an animal cell?
what is Plant cells possess a cell wall, chloroplasts, and a large central vacuole, while animal cells lack these features and instead have lysosomes.
Explain the difference between an instinct and a learned behavior, and give one example of each in animals?
what is An instinct is a behavior that an animal is born with and does not need to learn and A learned behavior is a behavior that an animal learns through experience or observation.
Design an experiment to determine if adding heat to a substance causes a physical or chemical change?
what is to determine if adding heat causes a physical or chemical change, you can design an experiment involving heating a substance like ice or water.
Compare and contrast static electricity and current electricity?
what is static electricity is the buildup of an electric charge on an object, like when you rub a balloon on your hair. Current electricity is the flow of electric charge through a conductor, like a wire, and it can create a magnetic field. Both involve electrical charges, but static electricity doesn't involve a continuous flow like current.
Imagine you are observing a river. What constructive and destructive processes might you see happening
what is Observing a river, you'd see both constructive and destructive processes shaping the land. Constructive processes, like deposition, build up landforms, while destructive processes, such as erosion, wear them down.
Explain how different types of cells work together in a living organism. Compare and contrast the roles of different microorganisms.
what is In multicellular organisms, different cell types cooperate through a division of labor, performing specialized functions to maintain the organism's overall health
How might an animal learn a new behavior?
what is Watching other animals and imitating their actions and Trying different actions until they find one that works.
Design an experiment to demonstrate a chemical change?
what is A classic experiment to demonstrate a chemical change is the combination of baking soda and vinegar, resulting in the production of carbon dioxide gas.
Design an experiment to investigate the relationship between the strength of a magnet and its ability to attract objects?
what is Students would need to develop a plan, such as using a magnet of varying strengths and a collection of objects of similar material (like metal) to observe the distance at which objects are attracted. Then, they would need to draw conclusions about the relationship between magnet strength and attraction based on their observations.
Develop an argument about whether constructive or destructive forces have had a greater impact on the Earth's surface over the last 1000 years. Support your argument with examples?
what is Over the last 1000 years, destructive forces have likely had a greater overall impact on the Earth's surface compared to constructive forces While constructive forces build up new landforms, destructive forces constantly break down and reshape existing ones.
How could advancements in our understanding of cells and microorganisms impact our future
what is advancements in understanding cells and microorganisms will significantly impact future health, environmental sustainability, and biotechnology.
Why are both instincts and learned behaviors important for animal survival?
what is Allow animals to adapt to changing environments and learn new skills that can help them survive in different situations.
