Based on the data table, which bridge should they select and why?
When building a bridge in real-life, there is a massive amount of planning and testing done to ensure it is safe and sturdy. This class had good plans and materials for building both bridges, but "Bridge A" seems like the most reliable choice for the science fair entry. It was able to hold up six toy cars and did not fall. It did wobble some so the class can make improvements on that portion of the bridge. "Bridge B" collapsed after the weight of three toy cars, so it doesn't seem like the most sturdy bridge.

How can we determine if a material is appropriate for a specific purpose?
How can we determine if a material is appropriate for a specific purpose?
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.

Straw, sticks, bricks, and mud are all materials that can be used to build a house. Which would be the best option and why?
Straw, sticks, bricks, and mud are all materials that can be used to build a house. Which would be the best option and why?
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.

Based on the data table below, which rock(s) should Jamal NOT use for the baseball?
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.

Jessa mixed sand and paperclips. She wants to remove the paperclips without touching them. Her teacher gives her the choice of three different tools to use. Which tool is best suited for removing paperclips without touching them?
Jessa mixed sand and paperclips. She wants to remove the paperclips without touching them. Her teacher gives her the choice of three different tools to use. Which tool is best suited for removing paperclips without touching them?
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.

Based on what you know about sponges, which item is most likely a sponge?
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.
