Blood Experiment

Our lesson for the first term is on Blood. As a culminating activity, we had Parent-Child Experiment to determine if Blood Type A can donate to Blood Type B or vice versa.

I did the experiment before our final experiment, and my children were telling me, “Wow, teacher, you are a teacher and a scientist. You are a scientist teacher!”

This simple experiment will make a child understand the concept.

Materials needed:

  • cups
  • test tube
  • dropper or pipette
  • food color (red and blue)
  • water
  • marker

Procedure:

  1. Label all cups (near the rim) with blood type names (A, B, AB, O).
  2. Pour water until half on all cups.
  3. Add a drop of red food color in Blood A cup.
  4. Add a drop of blue food color in Blood B cup.
  5. Add a drop of blue and red food color in Blood AB cup.
  6. Do not add any food coloring in Blood O.
  7. If the receiver is Blood A, then use a dropper to transfer the liquid in a test tube. Then, again use a dropper to add another Blood Type as the donor and see if there is a change in the color. If the color changes, it means that the blood types do not match.

Results:

  1. Blood O can donate to all blood types. In the experiment, it is colorless. Definitely, it won’t change the color of the receiver when it is mixed together.
  2. Blood AB can receive blood from all blood types.
  3. Blood A can receive from A and O.
  4. Blood B can receive from B and O.

After the Parent-Child experiment, the parents and children played Blood Game whereby we called someone who, for example, had Blood Type A, then those parents and children with matching blood types would huddle together.

It’s a fun way to make a child understand a challenging topic, and most of all, parents and children were able to spend time together doing a simple investigation!

Child’s first aid on how to stop bleeding: A talk by Mummy Christine

Do you think children should learn first aid? First aid is important because accident can happen anytime, and yes, children should learn the basic first aid because it is not at all times that adults are with them. When they know first aid, they will be able to help themselves in case of emergency.

Since we believe that first aid is a life skill that children should learn, we invited Mommy Christine to our school and share ways on how to stop bleeding. She taught our 5-6-year old children what to do when they have nose bleed and a cut.

What to do when there is nosebleeding:

Image from Google
  1. Sit down on a chair.
  2. Lean head forward.
  3. Pinch the soft part of nostrils below the bridge of the nose for at least ten minutes.
  4. Breath through mouth while applying pressure on the nostrils.
  5. Apply ice pack or cold cloth.

What to do when there is a cut:

Image from Google
  1. Take a clean cloth.
  2. Put it on the wound.
  3. Apply pressure to stop bleeding.

It had been a very informative and beneficial talk! Days and weeks after the talk, we have children sharing, “Teacher, I had nosebleed at home. I did what Mommy Christine said.”

Printmaking

Bored of doing painting, drawing, coloring or the usual arts you do with your children? Why not try printmaking?

Printmaking is an art technique of making prints. You can create print on a paper using any objects with various shapes and texture.

Here are the steps on how to do printmaking using string as a tool:

1. Prepare the materials that you need like paint, string, paper and magazines.

2. Soak the string in the water for half a minute or one.

3. Use two fingers to apply paint on a string.

4. Put the string on a paper in any design you want.

5. Cover it with another paper (magazine or newspaper) and press it as you gently shake and pull the string.

Remove the magazine, and there you will see your wonderful print design!

Heart Pump: A Science Project

Making a Heart Pump Model is a good way to make children visualize what happens when the heart pumps blood.

Here are easy steps on how to make a Heart Pump for your Science project:

1. Pour water in a jar until its almost full.

2. Cut the balloon’s neck.

3. Cover the top of a jar by stretching the balloon’s head.

4. Poke two small holes opposite with each other using a satay stick.

5. Insert a straw on each hole. 

6. Tape the balloon’s neck on one of the straws.

You’re done! Now, press the centre of the balloon cover (heart) to see how water (blood) moves…

Blood Donation Drive

To investigate more about blood, our K2 children went to witness a Blood Donation Drive. Here they had the chance to witness how a blood donation drive was done, observe how blood was taken out from a person, see the tools and equipment needed to take blood and interview a person who was knowledgeable about blood.

The children themselves were empowered to do the activity. They did a great job with their roles. They were seen serious with the task they needed to do. They knew the structure of a formal interview and how to operate a camera and an audio-recorder.

In the future, when similar activity is to be done, the event can be structured in this way:

1. Have children go around the different processes before a person can donate blood such as registering their names and then screening.

2. Interview the Donor Manager. Do a formal interview. Ask prepared questions.

3. Let children observe the blood extraction focusing on what needs to be done before taking blood, what are the tools and equipment needed to take blood and how blood flows from the person’s body to the bag.

4. Do an informal interview. Ask questions to the person who donated blood and the nurses. This should be done after the donation, and not when the blood is being taken out as this might stress the person donating blood and the nurse who is performing his/her duty.

5. Group photo and giving of tokens. At the end of the activity, pass the token of appreciation to the host as a sign of gratitude and then take a picture.

Overall, it was a good opportunity for the children to interact with various people to get information about blood.

Thank you Red Cross Singapore and NCS for accommodating our curious learners!

Blood Model: The Four Components of Blood

Learning about blood can be unfathomable to 6-year old children. However, with diagrams and models, it is easy for kids to have a better understanding of topics as such that might be too abstract for them.

Here is how we made the Blood Model in class to make children visualize the four components of blood.

Materials needed

  • white styrofoam – white blood cells (fight germs)
  • red cloth – red blood cells (carry oxygen from the lungs to all parts of the body)
  • red styrofoam – platelets (help in blood clotting to prevent bleeding)
  • water with yellow food colour – plasma (carry blood components to all parts of the body)
  • clear plastic water bottle

Procedure

  • Let the child put the white styrofoam, red cloth, red styrofoam and water in the bottle.
  • Add yellow food colour to make the plasma (water) appear yellow in colour.

As children put the materials in the bottle, the teacher or the adult may ask what each of the material represents. Also, the teacher or the adult can further ask the function of each blood component.

Setting up your classroom for the new school year

Teachers are not only teachers. They are interior designers, too. They plan and organize how their classroom would look like before welcoming a new batch of children. You might ask “How do teachers set up their classroom?”

Well, teachers setup their classroom based on what the school asked, what is appropriate to children, and of course, done according to the teacher’s personality.

As for me, I like a classroom that evokes positivity. So, I would put positive quotes around my classroom.

Take a look at the pictures below of how I designed my classroom in 2012, my first year in Singapore:

Children, parents and teachers who enter my classroom are greeted with positive notes, and they also leave with positive thoughts in mind, because I, myself, is full of optimism in life!

Have fun designing your classroom!

Active Health Fund Run 2017: A culminating activity of K1 Class at Learning Vision NCS

To mark the end of the term on the topic “Be healthy, exercise daily”, the K1 Class of Learning Vision NCS planned a Fund Run activity in collaboration with the Yio Chu Kang ActiveSG. The said activity was held last August 25 at the Yio Chu Kang Stadium. It was co-organized by YCK ActiveSG led by Parry Low and Stuart Low and by the K1 teachers of LV NCS – Teacher Sherilyn, Teacher Lin and Xia Laoshi with the support of the Centre Principal, Teacher Anisah.

Active Health is an initiative launched by the Sports Singapore with an aim to use sport to live a better and healthier life. This will form the basis of all future plans and programmes of the nation to achieve the objective of Vision2030 – a healthier population.

The K1 parents registered for this Active Health Fund Run, and the proceeds from this event went to our beneficiary, which is the Singapore Disability Sports Council. SDSC is an organization that provides sports training and development programmes for persons with disability. They are fielding the biggest away contingent of over 90 athletes to the ASEAN Para Games 2017 this September.

On this day, amidst the scorching heat of the sun, parents and children still had a great day as they were able to spend time with each other by doing various forms of exercises. The children ran 100m while the parents ran 800m. After the run, parents and children enjoyed playing active games like Bear Crawl, Tug of War, Maria Went to Town and Three-Legged Race.

Truly indeed that “it takes a village to raise a child”! The school, home and community have come together for this activity to support children’s development. We thank our K1 parents for participating in this event. We also thank the organizations we work with, the Yio Chu Kang ActiveSG and Singapore Sports Disability Council. Without you, this  event will not be a success! Our sincere gratitude to all of you!

 

Jurong Frog Farm

Overall, the trip was informative, and at the same time, fun and engaging for the children! The programme offered was carefully and meaningfully designed for children. It’s definitely worth a visit!

 

Choice Theory: How and why people behave that way

We often hear Maslow’s Hierarchy of Needs, which states that people are motivated to achieve certain needs. When the first level of needs is satisfied then the person will move up to satisfy the next level. There is another theory in human needs related to Maslow’s Hierarchy of Needs, and that is the Choice Theory.

Choice Theory is developed by William Glasser. This explains that human’s behavior and choices are influenced by their desire to fulfill their needs. The needs in Choice Theory is somewhat similar to the Hierarchy of Needs. Below are the five basic needs in Choice Theory:

  • Survival. This need directs us to behave or choose something in order for us to have food, shelter and others. Examples of Survival Needs are air, food, water, shelter, health and exercise.
  • Love and Belonging. This need requires us to be connected, accepted and appreciated by others. Examples of Love and Belonging Needs are friendship, cooperation, involvement, relationships, connectedness, companionship, intimacy and collaboration.
  • Power. This need is satisfied by achieving and accomplishing and being recognized and respected. Examples of Power Needs are importance, competition, recognition, achievement, competence, attention, respect, skills, being heard, impact, pride and significance.
  • Freedom. This need drives us to make choices and have the control of our life: to set goals, to create plans, to make choices, to evaluate results and to determine the next step. Examples of Freedom Needs are choices, independence, options, liberty, autonomy and moving around.
  • Fun. This need demands us to have joy and satisfaction in our lives. It is the result of accomplishment, recreation and entertainment. Examples of Fun Needs are enjoyment, pleasure, learning, relaxation and laughter.

When a person’s need is satisfied, he will feel the pleasure. Otherwise, he will feel frustrated; he will feel the pain. Whatever the person feels, it will affect his behavior or choices. How a person behaves then is internally motivated, and is not affected by external factors. We can only say what we want to say, but the decision to do it is not ours, but his!

I said a lot in this post, but the only thing I can give is information. Further decision or action is yours to make!
