Lego Robotics Water Conservation Challenge

What should you do?
Use legos to make a device that will tell you when to stop filling up the bathtub. Your creation must measure 2-4 inches of bathwater depth. It does not matter what kind of Legos you use. They can be regular size legos or Duplo-sized, as long as they are the Lego brand. Take a picture or shoot video of your creation with a small description. After you have created your Lego device, please submit your creations by posting to social media with the hashtag #whateverfloatsyourlego
Please Share!
Why should you do it?
  • This prevents us from wasting fresh water in the bath or shower.
  • The more water you use, the more water that needs to be cleaned, transported, and then recycled.  Not using too much water saves energy and resources.  
  • This is an easy way for kids to be involved in conservation.
  • We will recognize our favorite entries on our website and on the St. John’s Lutheran School Facebook page!
  • Kids love to build with Legos!
Why are we doing this?
  • Our team name is Eagle Tech.   We are a team competing in the First Lego League competition.
  • The theme this year is Hydro Dynamics.  As a part of the competition, we are looking at a problem. The problem is to look at ways to improve the ways people find, transport, use, or dispose of water.
  • Our team is looking at the ways people use water in bathtubs/showers.
  • We are trying to figure out how to tell people that they need to conserve water when taking baths.  Our solution is to ask people to create a small LEGO toy to make it fun to measure the water level in the bathtub so it is not overfilled.  We would like this video to be spread through social media so that more people can see it.

Our Top Entries of the Week:

2. These sisters use some of the Lego animals from last year's FLL challenge, Animal Allies. When the animals are underwater, you have enough water in your tub!


3. This creator said he color coded his creation.   It sits at the bottom of the tub and when water hits the yellow Legos you know you are getting close to having enough water.  When it hits grey, even closer, red is STOP... black is you have too much water!

4. This creation sits with the black stand on the bottom of the tub. When the water is high enough that the platform floats, you can turn off the water.  

5. When SpongeBob takes a bath, you can take a bath!
