Reducing resource use means just what it says using fewer resources. There are lots of ways to reduce our use of resources. Buy durable goods. Choose items that are well made so they will last longer. Youll buy fewer items in the long run, so youll save money as well as resources. Thats a win-win! Repair rather than replace. Fix your bike rather than buying a new one. Sew on a button instead of buying a new shirt. Youll use fewer resources and save money. Buy only what you need. Dont buy a gallon of milk if you can only drink half of it before it spoils. Instead, buy a half gallon and drink all of it. You wont be wasting resources (or money!) Buy local. For example, buy local produce at a farmers market, like the one in Figure 2.20. A lot of resources are saved by not shipping goods long distances. Products bought at farmers markets use less packaging, too! About a third of what we throw out is packaging.

Question: "What are two examples of repair rather than replacing?"

Response: "Fix your bike rather than buying a new one, and sew on a button instead of buying a new shirt"

Problem: How would the universe look without gravity? It would have no planets and no stars. Thats how it looked when it was young. When the universe was young, there was only gas and dust. From this gas and dust, everything we now see was made. How were stars and planets created from just gas and dust? The answer is gravity. The same gravity that holds you down on Earth. The same force that causes your pencil to roll off your desk. The same force that causes it to fall to the floor. The invisible force of gravity caused dust and gas particles to be pulled together. This force is what formed all the objects in our solar system. This force formed the smallest moons. It also formed our Sun. This force caused more than just our solar system to form. It caused all the other solar systems to form. It caused the formation of all the galaxies of the universe.

Question: "Did gravity cause more than one solar system to form?"

Answer: "Yes"

OPTIONS:
- no
- yes
Answer: yes

Question:
Mechanical energy is a combination of the energy of motion or position. This type of energy describes objects that are moving or could move. A moving ball can have energy from motion. An arrow can also have the energy of motion. Both are types of mechanical energy. Can you think of some other examples? Where does the energy of motion come from? It comes from the energy created by position. This energy is stored energy. This means it is not moving yet, but it has the potential to move. How can you store energy? The arrow gains energy from the drawn bow. As the arrow is released, the bow releases its stored energy and puts the arrow into motion. Can you think of some other ways to store energy using position? After reading the above, is "Energy of motion" the correct answer to the question "What kind of energy does a moving ball have?"? OPTIONS:
- no
- yes

Answer:
yes

Input: Magnets are able to place a force on certain materials. This force is called a magnetic force. The force a magnet exerts is a little different from the forces you may normally think about. You exert a force on a book when you lift it. You also exert a force on the pedals of your bicycle. In both those cases, those forces cause a change. The change you see in both these cases is called motion. Magnets, too, can produce change. They can produce motion just like you do. Unlike you, magnets do not have to touch something to exert a force. A magnetic force is exerted over a distance. Thats right, a magnet can push or pull certain items without ever touching them. Thats how the maglev train works. Do you know another type of force that does not require objects to touch? These forces are known as non-contact forces. Another type of non-contact force you may be familiar with is gravity. Gravity too can cause changes in motion. Gravity holds our moon in orbit without touching it.
"What are non contact forces?" is "Force that does not require objects to touch"?

OPTIONS:
- no
- yes
Output: yes

Input: The dermis is the inner layer of skin. The dermis has blood vessels and nerve endings. The nerve endings explain why your skin is sensitive. You can sense pain, pressure, and temperature. You cut your finger and it starts to bleed. What has happened? If your skin bleeds, it means you have cut the dermis layer and damaged blood vessels. The cut really hurts. It hurts because of the nerve endings in this skin layer. The dermis also contains hair follicles and two types of glands. Hair follicles are structures where hairs originate. Each hair grows out of a follicle. Hair passes up through the epidermis. It then extends above the skin surface. Oil glands produce an oily substance. The oil is secreted into hair follicles.

Does the response "The dermis has oil glandes" correctly answer the question "Why do I feel pressure when someone pokes me?"?

OPTIONS:
- no
- yes

Output: no

Input: In actual practice, however, we act too often as if we only cared for economic values. If we are to live up to our educational profession, we must look our aim in the face and honestly practise what we believe. While training of character and conduct is the accepted aim for education in general, to make this useful and practical each teacher must fix her attention on how this ultimate aim affects her own special part of the whole work. By watching the free child she will discover how best she can help him: he knows his own business, and when unfettered by advice or command shows plainly that he is chiefly concerned with _gaining experience_. He finds himself in what is to him a new and complex world of people and things; actual experience is the foundation for a complete living, and the stronger the foundation the better the result of later building. _The first vital principle then is that the teacher of young children must provide life in miniature; that is, she must provide abundant raw material and opportunities for experience_.

Does the response "By guiding every step of the child education with advice and command" correctly answer the question "How can a teacher discover the best way to give a strong foundation for complete living?"?

- no
