Will our Cargo Ship float?

Building is fun, but testing our designs can be even more fun…especially if you get to sink a boat! Making mistakes is part of the engineering process! It helps us to figure out what does NOT work, so we can design it better next time. This experiment encourages you to engineer a stronger boat. You can use strategy and predictions to determine how much weight your cargo ship can carry! Have fun!

Design & Build a strong Cargo Ship!

Materials:

  • Aluminum Foil
  • Painters Tape
  • Large bowl or bin that can hold water
  • Water
  • Pennies, feathers, paperclips, cotton balls, or other small items of varying weights

Step 1: Fill your bowl up halfway with water  

Step 2: Using a piece of aluminum foil (try starting with an approximate 12 inch square,) fold the aluminum in half and then fold up each of the four sides to have a lip around 1 inch tall. Experiment with how many times you fold the foil sides (Do more folds make them stronger? What makes the boat heavier? Are taller or shorter sides better?

Step 3: Wrap tape around the edges to see if sealing the sides helps keep water out.

Step 4: Place your Cargo Ship into the water in your bowl

Step 5: Choose some items to place in your ship. You could start with cotton balls first. How many cotton balls will your ship hold?

Try paper clips next…

How about coins?

Does your boat hold more pennies or more quarters?

How many coins does your ship hold before it sinks?

Try this experiment with a friend and see whose ship holds more cargo!

Have fun being curious and creative!

From the Front Line of Education- The Impact of Distance teaching… on Teachers.

tag! Board Member, Kaneika Nimmons, is a Behavioral Dean at a St. Johns County Title One school. The weight of being separated from the students she serves daily is heavy, but drives her.

“As I placed my groceries on the counter, I found myself in a mental whirlwind. I felt as if my mind was playing tricks on me. I had already sanitized my grocery cart five times, but I still felt it wasn’t enough. My social distancing radar was in full effect and if it were a real thing, sirens would be wailing, alerting me of the masked woman standing in line behind me, who seemed to inch closer and closer towards me every second. I began to ponder, is she wearing a mask to protect herself from others or to protect others because she is suffering from the infamous COVID-19? My emotions were on overload, all while praying the cashier wouldn’t take offense to me placing my coupons on the counter instead of in her gloved hand. 

The feelings of being in a real live horror story were interrupted by the high-pitched sounds of, “Mrs. Nimmons, Mrs. Nimmons!!” I looked up to find a very excited, bright-eyed kindergartener, who attends the school where I work. Her arms were stretched wide, as she ran towards me. Through outbursts of laughter, she gave me a tight squeeze and asked, “When are we going back to school?” At that moment, the social distancing rules did not apply, as I was so grateful. Grateful, that a five year old little girl, took me from a place of darkness and brought me back to a feeling of hope, a feeling that everything was going to be ok. 

My eyes followed the student until she and her mom were no longer in sight. As I exited the store and walked to my car, my thoughts were again in a mental whirlwind.  Are they eating? Do they have adequate shelter? How often and how long are they left at home alone? Are they being  neglected? Are they in an abusive situation? Do they have the necessary supplies and materials for an effective homeschool experience? Daily hugs are so important, are they getting them? Are they surrounded by or lacking unconditional love? In the absence of the daily adventures of being surrounded by over eight hundred kids, these are just a few questions that consume my entire existence. 

Amid the COVID-19 pandemic, the lives of every student, teacher, administrator and school-based personnel have been forced into a new normal. This new way of existing comes along with an abundance of losses, for students and teachers alike. During this devastating time, we miss our students, we worry about our students, we love our students and pray they are well. As we press forward, in this new normal, we will remain on the front lines of education, giving our best effort, to be the calm in the storm for our students, remaining hopeful, that everything is going to be ok.”
