Emma's Adventure to the Science Musuem Pt 2
Emma's Adventure to the Science Musuem
The Microbe display caught my attention. The four pictures below are from the display.
The arrow pad that I am standing on is an example of a robot. By standing on a certain arrow I was able to answer the questions on the screen.
This is the cheat sheet that they had posted by the Microbe Quiz station. The separate pieces of paper, picture, and bolded microbe names all made it easier to reference the information quickly as I was completing the quiz.

Zoo Day!!!
Minnesota Zoo Robots and Signage
Day at the Zoo
Now we use their fossils to learn more about evolution.
Lights are something that you use in your every day life but some people use them in their job, to enhance shows. They are controlled through a switch board.

Robot Capture #1: Automatic Doors

When was the last time you walked through an automatic door? Did you know you were interacting with a robot when you did? Why do you think engineers designed automatic doors? Where are they most useful? What are the drawbacks of automatic doors?
You might be wondering how automatic doors work. Most use devices that sense your presence by either bouncing some wave off you or by passively detecting waves that you emit or reflect. The wave-bouncing detectors emit high frequency (ultrasonic) sound waves or radio waves and then look for reflections. If they detect changes in the intensity or frequency pattern of the reflected waves, they know that something has moved nearby and open the door. The passive detectors look for changes in the infrared or visible light patterns reaching a detector and open the door when they detect such changes.
