Journey Trip to the Bog

October 17th, 2011 by · No Comments · field trips

The Journey class took our 3rd annual trip to work on our habitat restoration project over at Ronald Bog.  The Sustainable Shoreline organization has a section of the park where the bog is located that they have replanted with native plants which provided shelter an habitat that the invasive species do not, and the native plants are GROWING like crazy, but in order to keep the native plants healthy, someone has to go in and remove the invasive species such as the ridiculously common Himalayan blackberry and Japanese knotweed, which will quickly chose out native species if left unchecked.

For the last 3 school years, the Journey program at RNCS has taken field trips at least once a year (hopefully twice this year) to work on removal of invasive plants to help keep the replanted natives healthy.  This year we pulled out nearly our combined volume in blackberry and knotweed plants, creating whole new corridors for natives such salmonberry, thimbleberry, red-twig dogwood, snowberry and many more important native plants to thrive and produce food for wildlife species in the area.  Good Job Kids!  Also, a big thanks to our chaperones: Gienna, Linda and Bob, and our fearless volunteers from Sustainable Shoreline – Boni Biery Bill Bear.  It was a great, and highly productive day.

 

Oobleck & Gak: The recipes

September 26th, 2011 by · No Comments · science links

All of my students have been introduced to, or had a chance to experience oobleck and gak over the past two weeks – both are strange substances with some of the properties of solids and some properties of liquids.  They are also extremely fun to play with.  There are many recipes for Oobleck and Gak out there, and I am linking to some of my favorite recipes.

Oobleck is easier to make – it works every time – while Gak requires that you be a bit more fiddly about ingredients.  For example, “School Glue” does not work for Gak recipes made with liquid laundry starch, it must be Elmer’s Glu-All in order to have the right chemical reaction and the right Gak-like texture.  Gak made with Borax may work better but is also somewhat toxic and must be kept away from mouths and from younger siblings.

Welcome to 2011-12

Welcome to my science blog this year.  Be aware that many of the “recent posts” are actually from a while ago, as I have been using different online tools the past couple of years, and am just getting back to using this Blog.

This will be a place for Room Nine students and parents in grades 3-8 to find information about what we’re doing in science and math this year.  I will be attempting to update at least weekly, with information about what we’ve been studying, links to interesting related sites, and necessary information about homework.

Welcome, I hope you visit often!

Mind the Gap – 3rd to 6th Grade Science in late November and December

January 8th, 2010 by · No Comments · Uncategorized

My sincere apologies.  I wish I’d been able to keep this fully up to date, but there were a couple of weeks when technical problems and just plain busyness got the better of me. This post will be a general update of what students did in science during the gap in communications.

Grades 3 & 4

We have been studying insects and working on our Bug Books.  Some parts of this project were done as a whole group, some parts in small groups and some parts were completely individual.  The final product is due on January 19th, 2010, turned in to homeroom teachers so that we can put it with your portfolios.

Assignment: Bug Book

Due Date: 1/19/10

Grades 5 & 6

While we spent some time in November and December on cells – what are they, what are they made of, how do they work? We also looked at identifying living things using dichotomous keys and we practiced with jellybeans – identifying the flavors based on color patterns- and on simple drawings of imaginary beings, but these kinds of keys are used all the time in the identification of different types of plants and animals that are actually a part of our world. In December we moved on to studying the scientific method in general, and how to write scientific questions, procedures, and hypotheses.  We will be focusing for at least the next month on scientific methods, and we are leading up to science fair projects.

Class Update – Science Week of 11/16/09

November 24th, 2009 by · No Comments · class updates

Grades 3 & 4

Last week we looked at honeybees, and today we continued our study of insects by studying cricket behavior today. Students observed crickets and over a 3 minute period, we studied what the crickets spent most of their time doing.  Before we started watching the crickets, kids predicted that they would be jumping and singing, but most of the time the crickets just found a dark corner and sat.  I introduced a project we will be doing between now and the Winter Break called the “Big Bug Book” where your kids will be putting together a book about insects, arachnids and other “bugs”.  This includes illustrations and a little bit of text.

Assignments: Cricket Observations, introduced the “Big Bug Book”

Grades 5 & 6

Because of the 4th and 5th grade field trip on Wednesday, our class was cut a bit short this week, but we did an introduction to cells with a focus on getting an idea of what the parts of a cell are and what they do.  We won’t be spending a lot of time with this, but it’s useful to have a general idea of what cells are when talk about the differences between plants, animals, bacteria, fungi, etc.

Assignment: Your school as a Cell, Organelle interview

Grades 7 & 8

Many 7th and 8th grade students still owe me lab write-ups for the baggie garden experiment or plant life cycle posters.  These must be in by 11/25 in order to count, as I have to start doing grades, and these are a part of the grading process.  This week we were going into more depth about cells, examining our jello cells, drawing cell pictures, taking notes, comparing the cell to a factory, etc.  We also started eggs soaking in vinegar to remove the shells while keeping the membrane intact.  We will use these next week for experiments on osmosis and diffusion.  We also started learning the parts of a microscope for a more detailed microscope lab next week.

Assignments: Cell as a Factory, Vinegar eggs, (overdue) Baggie Garden Write-up, (overdue) Plant Life Cycle Poster.

Science Update – Week of 11/9

November 13th, 2009 by · No Comments · class updates

Grades  7 & 8

This week the focus was on cells – we drew diagrams of cells, and made model cells from jello and various candies.  Students took notes on the functions of different structures within the cells.  In this coming week, we will look at some of the crucial processes that make cells work, such as osmosis, and we will examine various cells under the microscope.

Assignments: Cell Diagrams & Notes, Jell-O cell model

Grades 5 & 6

We only met once this week, and it was a short class, but we introduced the idea of cells – what are they, what do they do for living things, and watched several BrainPOP movies about cell structures.

Assignments: Exit Ticket on Cells

Grades 3 &4

Students read about bees, and worked on questions about how bees make honey.  If they didn’t finish the bee packet in class, they were supposed to take it home and finish it for homework.

Assignments: Bee Packet

Science Update – Week of 11/2/09

November 13th, 2009 by · No Comments · Uncategorized

Grades 7 & 8 Science:

We’re working on learning the structures and functions of cells.  On Monday we had a discussion about what we already know about Cells, and Tuesday we devoted some time to finishing up assignments that were due the previous week, as well as beginning to study the different cellular functions.

Assignments: Turn in Life Cycle of a Plant, and Lab Write-Up.

Grade 5 & 6 Science:

We finished plant life cycles Wednesday, and students turned in labeled drawings of a plant life cycle. We also spent some time working on observations by observing the larval crayfish that came from my crayfish pair.

Assignments: Life Cycle of flowering plants – labeled drawings, crayfish observations.

Grades 3 & 4 Science

Thursday 11/5 we spent some time reading about hydroponics and how they can be used to grow plants on a space station, and we practiced making observations of the larval crayfish.

Assignments: Observations of crayfish
