Plant Experiment #2 – The Job of the Stem

As part of our plant unit we have been doing a series of experiments to demonstrate the ‘jobs’ that each part of the plant has in the healthy growth of the whole plant.  This experiment showed the role of the ‘stem’.

We put a stalk of celery and a white flower into a jar with blue food-coloured water.  The next day we noticed quite the difference! Students learned that the job of the stem is to suck the water up from the roots to share it with the rest of the plant. The addition of the blue food colouring showed that this process took place in our experiment.

Plant Experiment #1 – The Job of the Roots

As part of our plant unit we have been doing a series of experiments to demonstrate the ‘jobs’ that each part of the plant has in the healthy growth of the whole plant.  In this experiment we wanted to see what would happen to a plant if it was separated from its root system.  We took two identical plants.  We put one into a new pot; the other we put into a second pot but we cut the root ball off of it first.  Both of these plants have been placed side-by-side on the window ledge so that they both received equal sunlight.  They also received equal amounts of water.  Three weeks later you can see what has happened … Students learned that the role of the roots is to suck water up from the ground, which is then sent to other parts of the plant.  Its second job is to hold the plant securely in place so that it doesn’t get blown away.

Value

In our Art classes we have been studying the element of Art – ‘value’.  Students have learned where the colour that we see is (in the light) and that white and black are NOT colours.  White is the lightest light and black is the darkest dark.  Without light there is no colour.

Students worked with white paper and only a black wax crayon to create a picture. They used ‘contrast’ – a sudden change from dark to light – and ‘gradation’ – a gradual change using the difference in pressure of crayon on paper. The lighter the touch the lighter the result, and vice versa with darkness.

Value is not only with blacks, whites, and greys.

Last week students learned that when black is added to a colour (red, orange, yellow, green, blue, violet) that the result is not a change in colour but that it becomes a darker ‘shade’ of the original colour.  For example, when black paint is added to red it creates a darker, deeper ‘shade’ of red – it doesn’t become black.  Students were reminded that ‘shade’ comes from ‘shadow’, which they know is when there is less light.  In contrast to this, when white paint is added to a colour the result is called a ‘tint’ – a lightening of the same colour.  For example, when adding white paint to red paint we get lighter versions of red which we call ‘pink’.

Students used coloured construction paper, black wax crayons, and white chalk to create these pictures.  Many seemed to think that ‘snow’ was necessary – even in April with our ‘heat-wave’ 🙂

I think they look awesome!

Plant Study

IMG_4793

We have begun our plant study by making bags which have wet paper towels and beans in them.  These are taped to our windows so that they will have the sunlight needed to grow.  Students will be monitoring their seeds’ growth on their recording sheets.

We have also planted some flower seeds in individual pots, along with some beans and peas in other containers.

Over the course of the next several weeks we will be doing many experiments with plants.  Stay tuned …

 

Badminton Lessons

Students had a great week of badminton lessons last week.  Coach Thomas taught them the correct way to hold the racket and how to hit the birdie.  They also used balloons to learn how to be gentle with the rackets and to use a light touch to keep the balloons aloft.

Many students were able to keep the balloon in the air for a long time.  Some counted over 100 hits before the balloon got away from them!!

Report Cards

Hi all,

Term two return cards are being sent home tomorrow, Monday, April 4th.  If you have any questions, please make a note on your child’s report card envelope and return it to class.

Even if you have no questions, please sign the report card envelope and return it so we can use it to send home your child’s term three report card in June.  The papers in the envelope are yours to keep for your files.

JUMP Rope for Heart 2016

Tomorrow morning we will have an assembly put on by the Heart and Stroke Foundation.  Our representative, Sandra Griffin, will be running the assembly.  She will discuss the things that we should do to ensure a strong and healthy heart.  She will also talk about the annual fundraising campaign.

At Rosser we have been very involved in this activity for many years.  This is our 18th year of hosting a fundraising campaign and actively participating in a ‘JUMP’ event!!

Tomorrow afternoon students will be bringing home a letter explaining the programme.  They will also have a fundraising envelope and a paper heart.  Please help your child fill in the heart with the name of someone that they, or your family, knows who has been affected by heart or stroke concerns.  This should be returned to school so I can ‘build’ our heart wall in the gym.  If you can, or choose to, please consider making a donation to this worthy cause. There is information on how to participate on-line which makes it rather easy to do.  Students may also win prizes based on their fundraising.

Last year 40 students participated in Rosser’s fundraising.  If we have one more this year (so 41 students) then the school will be awarded a special set of gym equipment. Last year our little school raised $3101.81 for the Heart and Stroke Foundation!!!!  That is a truly amazing number for such a small school.  Income tax receipts are issued for deductions.

Our actual JUMP event will be on the afternoon of Friday, February 26th from 1:05 – 3:00.  Students will be jumping with their buddy class.  It is a lot of fun that the students really enjoy.
