Snapshot: 7A Popcorn Container Challenge
Last Thursday, 7B took their class to the garden for a design challenge. They were given a piece of 8.5 x 11 paper and challenged to construct a rectangular prisms popcorn container with the largest volume. They had access to scissors and tape. Their container was then filled with popcorn.
There were lots of interesting ideas at the beginning:
-"All the volumes will be the same because we all have the same size piece of paper."
-"A taller container will hold more."
-"A container with the largest surface area on the bottom will be the biggest."
They went to work and as the containers were constructed and volumes calculated and recorded, they were able to refine their hypotheses. We will follow up on class this week with further analysis of their findings.

Snapshot: 8A Food Deserts
Berkeley, CA |
This year, the class took on the idea of food deserts. This is a project I have been tossing around for about a year. The essential question was, "What is a food desert? Who is impacted by food deserts?" We researched and defined a food desert. They looked at research about the impact of food deserts. For four classes, a group of students were charged with locating grocery stores on a set of maps from AAA of the Bay Area, Lake Tahoe, and Portland, OR. They had to cut out 1-mile radius circles to represent the reach of the grocery store. The areas that were not covered by the circles are defined as food deserts. These maps are not comprehensive because we were limited in time, but students were able to get a sense of how food deserts occur and who is impacted by these deserts.
Our discussions centered around how they live in an region of the country were access to fresh fruits, vegetables, dairy, and whole grains is easy. They recognized the high density of markets and grocery stores is high in the Bay Area and that affluent areas had great overlap of circles. Some students were able to recognize living in Northern California is not representative of the issue of food deserts. If we had more time and I had planned ahead, we would have done a second round of maps that represent cities where food deserts are a significant issues, such as New Orleans, Atlanta, and Detroit, and compared maps with the Bay Area. I would extended this to look at grocery stores per capita and other ratios that might have helped us understand the issue.
This activity turned out better than I had hopes and I was pleased with how we were able to use math to explore this topic. I look forward to refining and extending this project for future classes.

Snapshot: 8A Barbie Bungee Jump
Students are always asking,"When will I ever use this?" in math class. I do my best to give them real world contexts for the skills they are learning. In the 8th grade, we began the year learning about linear functions and figuring out how to graph them. To help make these skills real, the students did an activity where they had to use linear functions to figure out how many rubber bands a Barbie required to get the most thrilling bungee jump off QLab 201's balcony (16 feet). Thrilling was defined as getting as close to the ground without actually touching the ground. Here is a compilation of shots from our jump day.
Thank you to Blake Hansen for the video footage and editing.

Make Way for Fishes (in the Reef Aquarium)
Today was the day so many BPC students were waiting for... fish in the reef tank! (Although, as a science teacher, this blog post author does think that vertebrates get an unfair share of the love--invertebrates are pretty awesome and important, too!) You can check out the video of the fish release below.
Here is the list of fish added:
One Coral Beauty Angelfish (Centropyge bispinosa) - These fish are omnivores--they eat algae and are also known to nibble on soft coral. Like the Cardinalfish above, the Coral Beauty is in the Chordata phylum, Actinopterygii class, Perciformes order, though in a different family.
One Algae Blenny (Salarias fasciatus) - This fish is also in the - you guessed it - Perciformes order and there are 13 species in the genus Salarias. This
Blenny is best known for eating the algae growth from rocks and glass,
although they are primarily detrivores--scraping material off hard
surfaces such as rocks and coral. Blennies end up eating protists such
as filamentous algae, diatoms, foraminiferans as well as tiny
crustaceans, detritus, and sand. This fish can grow up to 5" in an
aquarium--that's one big Blenny!
One Orchid Dottyback (Pseudochromis fridmani) - Also in the Perciformes order, these fish are found only in the Red Sea. Orchid Dottybacks are carnivores, and will even prey on bristleworms!
One Flame Hawkfish (Neocirrhites armatus) - Also in the Perciformes order, Hawkfish belong to the family Cirrhitidae which has 12 recognized genera and 38 species--one of these is the Neocirrhites armatus! Like most hawkfishes, the Flame Hawkfish lacks a swim bladder--instead it spends a lot of its time perched on rocks, or dwelling on the sandy tank bottom. Their lower pectoral fin rays are also thickened, which helps to wedge them places and and hold them in a current (which, in our tank, comes from the powerheads). Perching helps them conserve energy.
Five Banggai Cardinalfish (Pterapogon kauderni)
- These fish can most often be found swimming around in a group in our
tank. They are named after the Banggai Islands of Indonesia, their
natural home. They are in the Chordata phylum, Actinopterygii class, Perciformes order, and are the only organisms in their genus Pterapogon!
A fun fact: the Banggai cardinalfish is a paternal mouthbrooder--which
means the male carries the eggs in his mouth while they incubate! Read
more about it on this Creature Feature at the Seattle Aquarium or watch this video to see mouthbrooding in action. Or this video, hilariously entitled "Banggai Cardinalfish With Big Babies In Mouth"!

The Invertebrates Have Arrived in BPC's New Reef Aquarium
BPC Reef Tank - September 2016 |
On September 12th, the first animal was added - a pioneering hermit crab. (You can watch the video of Mr. Nelligan adding this pioneering invertebrate by clicking the video below or accessing this link.)
Invertebrates awaiting their release |
- a few Nassarius snails - These carnivorous snails are scavengers and are important members of the reef aquarium's cleanup crew. Nassarius is a genus under the phylum Mollusca and class Gastropoda, and there are many, many species in this taxon! If you look carefully, you'll see them buried in the sand with just their proboscis ("nose") sticking up until it is feeding time.
- A Stomatella snail - These snails look more like slugs than regular snails, although they do have small flat shells. They belong to the Stomatella genus in the phylum Mollusca and class Gastropoda, and there are around 20 different species. These snails are herbivores, and help keep the tank clean of algae.
- A Trochus snail - Trochus is a genus under the phylum Mollusca and (you guessed it) class Gastropoda, and there are about 24 species in this genus. [UPDATE: We now have two in there, as a second Trochus snail hitchhiked on an incoming rock!]
- A number of crabs - these scavengers (all in the phylum Arthropoda) help keep the tank free of uneaten food and algae, especially of "nuisance algae" and cyanobacteria (also known as "red slime algae"!)
- Four Emerald Crabs (Mithraculus sculptus)
- Two Red Legged Hermit Crabs (Clibanarius digueti)
- Two Halloween Crabs (Ciliopagurus strigatus)
- One Decorator crab - Decorator crabs are part of the superfamily Majoidea (although not all Majoidea are decorators). Decorator crabs may belong to a number of different genera. It looks like we have a Spider Decorator Crab (Camposcia retusa). Decorator crabs stick materials from their environment on themselves for camouflage.
Sonam watches as the decorator crab is dropped into the tank. |
- One Tiger Tail Sea Cucumber -This scavenger is an omnivore and in the phylum Echinodermata, most likely in the genus Holothuria. Fun fact: these sea cucumbers have the potential to be poisonous if stressed, which shouldn't happen unless it gets sucked into a pump or something. [UPDATE 9.26.16: Erin suspects the sea cucumber has been eaten by the crabs and or the Nassarius snails! So, it is either buried in the sand or digested (also known as being "at one with the system"!)]
- lots of other tiny invertebrates, like tiny worms, sea stars and shrimps got in there, too!
Last Tuesday, Erin added two living rocks, two powerheads (flow pumps), and lights to our tank. The powerheads are held to the glass by powerful magnets.
Erin adjusts the underwater fans. |
The powerheads provide a turbulent water environment for these sessile (or non-mobile) organisms. Because some animals are attached to the rock, their food must come to them. They passively wait for food to pass by and touch their tentacles--then they discharge their nematocysts (basically tiny, poisonous harpoons) to capture their prey and draw it toward their mouths. (Check out this cool video of sea jelly nematocyts firing!) The fans are also necessary to blow the animals' waste away from them. (Fun fact: these simple animals have one opening--food goes in and waste goes out of the same hole!)
The LED lights are on timers and give a rhythm to the reef creature's day. Since many of the organisms are photosynthetic autotrophs, they need the light to make their own food. And the creatures need the darkness to know when to sleep!
We've even started a little reef library in the lobby (pictured left), and some students made welcome paper flowers for the crabs (pictured right).
Stay tuned for even more tank news!

Tapigami in BPC Art Classes
Today, BPC 7th graders had the opportunity to learn Tapigami with Danny Scheible in the art studio. Danny created his art form while studying contemporary and fine art at the University of California, Santa Cruz. Now he travels the world teaching Tapigami and making work on commission for museums, galleries, private collections and, of course, the san Mateo Maker Faire! You can see more of his work on his Instagram.
The BPC community is invited to learn, too! Come join us at the upcoming Art Exhibit where 7th graders will have a booth were they will teach others the art of Tapigami!
At its core, Tapigami is the art of applying imagination to rolls of tape. Any kind of tape – but mostly masking tape. (website)
