What do we know about the structure of living things? How do we know what we know about the structure of living things? How do we know that what we know about the structure of living things is correct? What do we do to improve and/or revise what we know about the structure of living things? How does our understanding of the structure of living things help us understand the natural world?
What we know about the structure of living things That the cells, tissues, organs, and organ systems make up our body by working together. Different things (bone, skin, etc.) in the body help protect it. An organ can effect more than one organ system. Blood cells are produced in bones. Although the many organs, bones, and systems make the body so complex, it is really made of cells-the building blocks of life.
How we know about the structure of living things By going to museums with specimens of experiments that professional scientists did. And looking at the explanations under them. We do labs in science class that help us understand where things in the body are located and how they work together. We look through microscopes to see the cells and tissues up close. Then we can compare data and make sure we all understand it. We can compare information from animal organs/bodies with those of a human because they are very similar. That way we can see the internal body up close. =
How we know about the structure of living things is correct By using previous knowledge and research we can compare the data and see if we made a mistake. We can do multiple trails to find and average. If any data isn’t anywhere close to the average, we would know it was incorrect. We can use data from tests that scientists have previously done. We can find this data in books, the internet, and magazines. We can go over the answers in class with Mr. Bormann (a teacher) and our other classmates. If the answer a group has is different than everybody else’s, the class can redo the experiment as a whole, or help the group that messed up. Working in groups is the strongest because if one person makes a mistake, everyone else is there to help them. And the person won’t know about the mistake until someone else has a different answer and points out that a mistake had to be made.
How we improve/revise what we know about the structure of living things We can look at experiments done by scientists to understand our mistakes. And then we can compare the data to see what they did, and what we can do. We can use posters in Mr. Bormann’s classroom, previous knowledge from prior labs, and research from the Internet, books, and magazines. This way we can look at what we’ve done wrong and see what we can do right. We can add more trials to see if the new data matches up to either of the old. And we can share data with other groups to see if it is similar. That way, we can come up with a more accurate conclusion, which is revision and improvement. Pay attention in class and use dissected animals to understand the mistakes we’ve made.
How our understanding of the structure of living things help us understand the natural world In class, Mr. Bormann said that if we don't know how our bodies work then we won't be able to cope with the problems we will all have with one or more organs in our body. So if we don’t know the structure of our body, then–since nature is similar—we will be clueless. When we dissect animals, we can see what our body looks like… because of the similarity. So understanding what the inside of our bodies look like, and how they work, helps us figure out how animals live. It shows us that if we didn't know about our body, then we wouldn’t know how the natural world works. This is because most of the structures in nature and the world today are based off of the structures inside of our body. Like the bone structure is like a honeycomb. And the Eiffel Tower is made based on the bone structure as well.
