5th Grade Interactive Science Chapter 2

How has technology helped us?

• We can study new things such as thermal vents in the ocean.
• It is fun to learn about technology.
• Technology is helpful to us. 
• Technology has not helped us at all.

Microchips have been helpful because they...

• can help doctors find illnesses within your body.
• They take images of bones without hurting the patient.
• They have made computers smaller and more affordable.
• They have made computers neater. 

The first step in the design process is to...

• research solutions.
• develop solutions.
• test a prototype.
• identify a problem.

Why would an engineer watch people using a computer keyboard? 

• to identify a problem
• to be a weirdo
• to solve a problem
• to learn to do research

What should a prosthetic hand be able to do?

• move in different directions
• close and open around an object
• pick up objects and set them down
• all of the above

To research materials and ideas for a prototype, engineers may use what resources?

• magazines
• internet
• encylopedias
• all of the above

Robots can be made to have human-like movements.  In a prototype robot, the wires and strings are like what?

• the skeletal system
• muscular system
• brain system
• a prosthetic hand

Which is the correct order of the design process?

• identify a problem, develop possible solutions, conduct research, test the prototype, and then build the prototype,
• Build a prototype, test the prototype, conduct research, find possible solutions and then identify a problem.
• Identify a problem, research the problem, develop possible solutions, choose a solution, design and construct a prototype, and, finally, test the prototype.
• Identify a problem, ask your friends to solve it, and then go to bed.

What would engineers do after they built a prototype?

• Evaluate the prototype, improve it,  and then reevaluate the prototype to make it better.
• Evaluate the prototype, but throw it out if it does not do well.
• Show the prototype off to their friends.
