The following technologies have been recently developed to provide solutions to various problems. Determine what pollutant is being addressed, what system is impacted, and the scientific
idea upon which the solution is proposed.
. A new motorboat has been developed that is powered by solar panels on its roof, making it entirely electric.
"
A method of making chlorine from dissolving salt (NaCl) in water has been developed.
"
A new floating trash bot prototype has been developed.

Sucrested Solution
What pollutant was this
solution designed to remove?
What system is directly
impacted by this solution?
What scientific idea supports
this solution?
Boat with solar panels
Lack of sewage treatment plants
Liquid chlarine made from
water and regular salt
Lack of disposal opportunities
Trash bot
The technologies mentioned above had the following criteria and constraints
Boat with solar panels
Technology
Criteria
No emissions, large enough to carry people
Safety, cost
Liquid chlorine made from water and regular salt
Kills disease-causing bacteria, easy to use
Trash bot
Picks up floating trash, remote steering mechanism
Cost, safety
Weight, size
V
Constraints
During a presentation of each of the technologies, classmates were asked to evaluate and make recommendations for them. Evaluate their recommendations, and provide a reason for your
decision.
Technology
Boat with solar panels
Recommendation
Put solar panels along the side of the boat
so it will have more power and be able to
go faster.
Liquid chlorine made from water and
regular salt
Build a factory to make chlorine so that
more can be made.
Trash bot
Make it lighter so it can go faster.
