Explora Explorations~Water & Sound Waves

While Jackson & Jeremiah participated in this week's Homeschool Science Club class, Jenna and I explored our usual favorite exhibits...anything that included water!

Jackson & Jeremiah's class was called:
Classy Investigation (Grades 3–5)
We take the mystery out of animal classification! Students discover the five major vertebrate classes, build 3-D classification keys, and use their new skills to solve an animal mystery.

Taxonomy has always been one of my favorite subjects, so it was exciting discussing the classification of organisms, including mammals, birds, fish and insects. The rankings are separated into Kingdom, Phylum, Class, Order, Family, Genus, Species, and Subspecies, with over 40 various other ranks , such as subphylum, superorder, subfamily, subtribe, etc.(Which is very helpful in regards to classifying insects).
Jackson & Jeremiah learned mostly about the subphylum of Vertebrates, which includes most creatures with spinal cords or backbones. Vertebrates include: Fish, Amphibians, Reptiles, Birds, and Mammals. They seemed to enjoy finding out how to classify animals in a scientific way.

Here's Jenna playing at the water table. She created a River Rapid for her Triceratops to ride down stream.

Jenna enjoyed letting her Triceratops bury through the sand on the Erosion Table.

The details of the scales and skin on her plastic Triceratops fascinated Jenna.
Jenna creating watercolors using markers and a dropper.
Making music is one of Jenna's favorite things to do.

Jackson & Jeremiah never tire of this exhibit in the Sounds and Vibrations area. It's called Sound Circuits, and here they can create their own personal Soundbytes using various sounds and rhythms. They then record it and play it back. Jackson is below making the background sounds for a 'music video'.

Jeremiah and Jenna exploring an exhibit called a "Nomograph", which basically shows the speed of sound by measuring between the wave lengths when the water vibrates from the sound played.
