In this activity, you created a passing drill in which the sprites sensed other sprites,
the edge of the stage, and key presses.
Scratch’s “sensing” blocks allowed you to make a fun, interactive game.
Computer scientists use a computer’s ability to sense to make their programs react to the
world around them.
Many sensing computer programs are used to help others and improve or even save lives.
Thats pretty powerful stuff.
For example, sensors alert rescue workers to the location of natural disaster victims.
This robot uses infrared sensors to find warm areas.
Humans give off more heat than debris, so the warm areas are likely to be people.
This robot also uses sensors to map the land as it moves, so it is less likely to get caught
Robots can survive harsher situations than humans and find people more accurately, thanks
Sensors don’t have to be attached to robots to save lives.
This clip from the Open University Computer-Animal Interaction Lab shows how a dog uses special
sensors to help people with medical conditions.
So we are developing a dog friendly alarm system that diabetes electrons can use to go for help when the
human loses consciousness.
When the dog triggers the alarm by pulling a specially designed tag, the technology calls a family
member or the emergency services.
That’s pretty sweet.
The device senses when the dog pulls on the tag and sends for help, possibly saving the
life of someone who has fallen unconscious or had a seizure.
Computer scientists like you help save lives using sensors all the time!
Next time in Google CS First Sports, you will create a home run derby game in which you'll
calculate the player's baseball stats.
Get ready to crunch some numbers and improve your swing!
While you’re waiting for your clubmates to finish the wrap-up, take a moment to write
As you reflect on today’s activity, consider these words from American soccer legend Mia
She said “Failure happens all the time.
It happens every day in practice.
What makes you better is how you react to it.”
She would know!
With a grueling practice schedule, she led the North Carolina Tar Heels to 4 consecutive national
championships and 2 FIFA World Cup Championships with the Women’s National Team.
Her first was at age 15 and the other was an epic battle versus
China that came down to a single penalty kick.
Next time you fail at something, remember that it happens to everyone--even sports greats!
The best part is, you get to choose how to respond to failure and use it to help you grow.
See you next time.
