Explanations1. Heat is energy. After scrambled eggs are cooked with heat energy, they are not gooey anymore. They become solid. Cooked scrambled eggs are soft and fluffy.2. The rod will come out of the fire red-hot. The glowing red color is a reflection of increased energy added to the metal by the heat. The heat from the fire will also make the steel more pliable.3. An object's weight is always equal to the sum of the weights of its individual parts.

If each block weighs 1 ounce and there are 5 blocks blocks in the structure, it is possible to find the weight of the structure by adding the weights of the 5 blocks together.

1 + 1 + 1 + 1 + 1 = 5 ounces4. An object's weight is always equal to the sum of the weights of its individual parts.5. Heat is energy. Heat energy can change things. Heat changes a potato from being hard to being soft and mushy.6. The weight of the wall must be equal to the sum of the weights of all its parts. So, the architect could count all the bricks and multiply by three pounds, because that is the weight of each brick.

This estimate leaves out the weight of the mortar that holds the bricks together.

7. When things are mixed, some of their properties may change. For example, if red paint is mixed with blue paint, the color of the new paint won't be red or blue. It will be purple.

But sometimes when things are mixed, the properties of the objects or materials stay the same. For example, if red jellybeans are mixed with blue jellybeans, the properties of the jellybeans stay the same. The objects are just together in the same container.8. Ice is a solid. Water is a liquid. Melting is a change from a solid to a liquid.9. The Law of Conservation of Matter say that the amount of matter in a whole object is equal to the amount of matter in the sum of its parts. So, the weight of a whole object is equal to the sum of the weights of its parts. This is why the weight of the full backpack is equal to the sum of the weights of everything in the backpack, plus the weight of the backpack itself.10. The Law of Conservation of Matter says that the amount of matter in a whole object is equal to the amount of matter in the sum of its parts. So, the weight of a whole must be equal to the sum of the weight of all its parts.

This law applies to the group of marbles. The weight of all the marbles together is equal to adding up the weight of the eight individual marbles.11. The weight of an object is equal to the sum of the weight of its parts. In this case, the total weight of the cubes that spell out the words is equal to the weight of each cube times the number of cubes (letters) in the word.

So, the total weight of the cubes that spell out "cage" is 12 ounces.

3 ounces X 4 blocks = 12 ounces12. A chemical change changes things into different materials. The new material might be very different.

Mixing baking soda and vinegar makes a chemical change. The solid and the liquid change into a gas. A gas is invisible and will spread out to fill the room. The gas is very different from the baking soda and vinegar.13. Many things change when they are heated. The air and sunlight will warm the ice cube so that it melts and becomes liquid water. So, the ice cube will be a clear liquid.14. A chemical change makes something change into a new material. The new material might be very different.

Burning a candle changes the wax and the wick into soot, ash, and gases. Gases are invisible, so it seems like the candle disappears. It does not disappear. The candle only changes into different materials.15. An object's weight is always equal to the sum of the weights of its individual parts. So, add together the individual weights of the parts to get the weight of the chair:

15 pounds + 2 pounds + 3 pounds = 20 pounds16. When liquids are cooled down, they may become solid. Milk in an ice cream maker freezes into ice cream, and it becomes more solid than liquid milk.

17. Folding a shirt changes its shape.

After it is folded, the shirt still has pink stripes, and it can still bend easily. Folding a shirt does not make it hotter or colder.18. The size of the half piece of toast is different from the whole piece.

Some properties of an object can be changed by doing things to the object. Cutting something into pieces makes more pieces, and the pieces are smaller. Wetting something might make it change color.

Mixing two things, like salt and water, might make a third thing (salt water) with some properties that are the same and some properties that are different from the things that were mixed.19. During the process of cooking, materials change into other materials with different characteristics.

Cooking is a chemical change that causes the identity of the original material to change. Chemical changes cannot usually be reversed. For example, it is not possible to "uncook" an egg.

Compare this type of change to physical change, which only causes changes in the physical properties of a material. An example of a physical change is a change in the state of matter (such as freezing or evaporating). In a physical change, the identity of the material stays the same, and the process can be reversed. For example, water can be frozen to create ice, which can then be melted to form water once again.20. When water is cooled in a freezer, it changes from a liquid into a solid. When water is solid, it is called ice. Ice takes up more space than liquid water, so when the water in the straw froze, it grew bigger and poked out of the straw.

So the water in the straw became a solid and it grew bigger.21. Sandpaper changes the texture of wood. It makes the wood feel smooth.22. Mixing red paint with yellow paint will change the properties of the paint. The new paint mixture will be colored orange.

Doing the other things will not change the properties of an object or material.23. Many things change when they are heated. Adding a little bit of heat can easily melt chocolate chips so that they become brown and gooey.24. Based on the chart, the waxed paper, plastic wrap, and desk top act the same when they get wet.

If a small amount of water is placed on them, these items will not absorb any of the water.25. Since an object's weight is always equal to the sum of the weights of its individual parts, the total weight of the suitcase plus the contents of the suitcase could not be greater than 15 lbs.

Since the suitcase already weighed 5 lbs, the contents could not weigh any more than 10 lbs. The only combination given that weighed 10 lbs included her clothing, shoes, toiletries, books, and

movies.26. Heat can make things change. When an egg is raw, it is a liquid. There is a clear part and a yellow yolk. After the egg is hard boiled, the inside of the egg is solid and the clear part becomes white.27. Cutting paper changes its size and its shape. The paper becomes smaller.

The paper is still white. It does not get hotter or colder, and it can still bend easily.28. An object's weight is always equal to the sum of the weights of its individual parts. If the total weight of the groceries and the bag was equal to 35 lbs, it is possible to find the weight of the canned goods by subtracting all of the other items from the total weight.

35 lbs - 1 lb - 4 lbs - 8 lbs - 2 lbs = 20 lbs29. As the sponge gets wet and soaks up water, it will get heavier.

Since water will go inside the sponge, the weight of the wet sponge will be equal to the weight of the dry sponge plus the weight of the water it has soaked up.30. Burning is an example of a chemical change in which a new material with different characteristics is formed. If you burn a piece of paper, the ashes that are left are no longer paper. They are a different substance.

Melting, tearing, and breaking are examples of physical change because the material created by the change has the same identity as the original material. For example, if you break a glass vase, the pieces of the vase are still glass.
