Different materials have specific purposes and are best suited for certain tasks. In this case, "Item 1" is not absorbent at all, and Grace is trying to clean up a spill. This item would NOT be the best choice to clean up a liquid. If Grace wants to clean it up quickly, "Item 3" would be her best choice instead!

Some materials are suited for a specific purpose and were designed to be the best material for the job. Analyzing the properties of a material can help someone to determine if it is a good fit for a specific purpose or project. An example could be analyzing the softness of an object if you want to turn it into a pillow. You do not wish to pick something hard or rough.

Building materials for a house have to be selected with a specific purpose in mind because the structure of the house has to be secure and safe. Of the four materials, the best option would be the bricks. Bricks are sturdy, stable, and reliable building materials. They are level, so they stack neatly and are not going to crumble or slide when wet. Straw, sticks, and mud would not be the best materials suited for this purpose.

"Bridge B" did well until a fourth car was added, so there may have been a failure in the materials somewhere. None of the objects they initially chose are very strong or sturdy, and if the gum were freshly chewed, it would be wet, and things could slide. By choosing building blocks that stack neatly and fit together well, very strong super glue, masking tape to wrap around the blocks, and paint for decoration, they may create a much stronger structure. Construction paper and tape are good for arts and crafts but may not be the best materials suited for bridge-building.

If Jamal is looking for a rock that is best suited to his specific purpose (replacing his baseball), he needs to find a stone that will not break when hit with the bat. The rocks that Jamal should not choose are "Rocks 1, 3, & 4" because they broke when shaken or squeezed. The best rock to use would be "Rock 2" because it did not break when tested at all.

Different materials have specific purposes and are best suited for certain tasks. Jessa has to remove small, metal paperclips without touching them. The size and color of the tool do not matter in this case, and they do not affect Jessa's decision. The bar magnet is magnetic, so it should pick up the paperclip when it is moved close to it. Magnets do not need to touch other objects to affect them if they have magnetic qualities. This would be the tool most suited to her task.

Materials can be analyzed to determine if they would work for a specific purpose. Someone can observe the properties of the object or material and see if it fits their needs. Absorbancy, magnetism, size, and shape are just a few properties that might make something suited for a specific purpose.

"Bridge B" did well until a fourth car was added, so there may have been a failure in the materials somewhere. None of the objects they initially chose are very strong or sturdy, and if the gum were freshly chewed, it would be wet, and things could slide. The materials selected were weak and not suited for this project.

Different materials have specific purposes and are best suited for certain tasks. In this case, "Item 1" is not absorbent at all, and "Item 2" absorbs some liquid. Background knowledge about sponges allows readers to recognize that "Items 1 and 2" do not have the characteristics of a sponge. They are porous, absorbant, and used to clean up spills. "Item 3" is described as very absorbent, so this item is most likely the sponge.

Different materials have specific purposes and are best suited for certain tasks. Angelica has to separate rocks from dirt in one minute. The size and color of the tool do not matter in this case, and they do not affect Angelica's decision. The sifter would be the best tool to use to get the job done quickly. She can scoop up the dirt and rocks into the sifter and shake it, so the dirt falls out, and the stones remain. She can repeat this until her one-minute timer is complete.
