Class Experience

Students will use what they learn about buoyancy and density to create a Lego boat that can hold a dry Minifigure.  Students will make and test design changes as necessary.
I have taught third-grade science in a classroom setting for four years.  I have served as my school district's third-grade science content expert.  I have also served as my school's science academic leader.  I have a Master's degree in biological anthropology.  More generally, I am an advocate for scientific literacy and I love exploring scientific concepts with students!

I have several years of experience teaching elementary science labs.  I always set clear safety expectations and actively monitor the class to ensure that these expectations are followed.
No homework will be assigned.
Required Legos-2 or 3 larger flat base plates of the same size (6 x 10 or larger) will be needed to make a Lego craft that won't sink I also recommend an assortment of other standard bricks (1x1, 1x2, 1x3, 1x4, 1x 6 2x2, etc.). Other supplies: 1) A container filled with 1-2 inches of water. I recommend a clear container (such as a Tupperware container) that is at least large enough to hold a standard peanut butter jelly sandwich. Smaller containers will limit the size of learner's boats. 2) At least 1 Lego Minifigure 3) Paper towels to wipe up spills. You may also want to cover your work surface with wax paper (optional)
Learners will not need to use any apps or websites beyond the standard Outschool tools.
At the end of the classes, each learner will share his or her boat with the class and discuss the design changes tested.
40 minutes per week in class, and maybe some time outside of class.
I will show a "Kids Want To Know" video that contains a brief cartoon image of the philosopher Archimedes' naked bottom.  I've chosen to show this video because it is more accurate and accessible than other videos on the topics of density and displacement.

Here is a link to the video if you would like to preview it:

The potentially sensitive content occurs at 2:16 in the video.
