Science Experiment: Oil and Water

Supplies Needed:

  • Food coloring
  • Droppers
  • Vegetable Oil

How?

  1. Put water in several cups and add food coloring to the water. Then stir to combine.
  2. Place a dropper in each colored glass of water.
  3. Fill a cup about half way with oil.

Result:

While enjoying this science exploration little giraffe friends explored how oil and water do not mix together. it is a great start to simply explore the two liquids and see how they behave when mixed together.

How Our World Works: “Sink”& “Float”

This week for the science activity, we talked about how do things sink or float. We brainstormed what things could float or sink. The first step, we introduced these two words’ meanings in English.

T: “What does it mean ‘sink’ and ‘float’?’

C: “Sth goes down in the water calls ‘sink’.

“on the top of water is ‘floating'”

T: “What do you think what things could sink?

C: “Blocks sink”

T: “What can float?”

C: “Balls are floating”

After the brief conversation we decided to go outside and collect some nature things that may sink or float.

 

We tried them in the water…

It gets the little giraffes thinking and predicting. We sorted out both sinking objectives and floating objectives. Some children made a comment that “Things are heavy can sink.”

Book Week Activities — Monday

Monday of book week, wearing PJs and reading the favorite stories, we had a chance to show friends our favorite books from home. The stories are in Chinese, English, and Japanese. For some friends that forgot to bring books to school, they chose their favorite books in the class. The little giraffes took a turn to introduce what the story about and one of their favorite picture pages. As little giraffe friends are building up the language skills, we’re encouraging them to use words to describe what their favorite stories are about. 

Book Week!

Dear parents,

I’ve shared the book week calendar with the little giraffe friends for next week. The little giraffes are very excited about the upcoming book events. Please remind your child to wear pajama and bring one of the favorite books from home next Monday. Next Friday, we will encourage everyone to dress up like your favorite story character and participate in Books Come Alive event which is arranged by PSA. 

For this week and next week, we are focusing on a series of stories by Eric Carle: Brown Bear, Brown Bear, What Do You See? Walter the Baker; Do You Want to be My Friend? Polar Bear, Polar Bear, What Do You Hear? From Head to Toe 

Celebrating Lantern Festival

The lantern festival marks the Chinese New Year Spring Festival period. To Chinese people, it’s a fun festival that people will go out to look at the moon, send up the colored lanterns, have a meal, especially have tangyuans to represent the meaning of family members spending time together.

In our class, we followed the traditions to make colored tissue collage lanterns and tangyuans. It was fun that exploring the things we’ve never done before.

 

Color Changing Milk Science Experiment

What You’ll Need:

  • Milk
  • Trays
  • Food coloring (red, yellow, green, blue)
  • Dishwashing soap (Dawn brand works well)
  • Cotton swabs

What To Do:

1. Pour enough milk in the dinner plate to completely cover the bottom to the depth of about 1/4″. Allow the milk to settle.

2. Add one drop of each of the four colors of food coloring — red, yellow, blue, and green — to the milk. Keep the drops close together in the center of the plate of milk.

3. Find a clean cotton swab for the next part of the experiment. Predict what will happen when you touch the tip of the cotton swab to the center of the milk. Did anything happen?

4. Now place a drop of liquid dish soap on the other end of the cotton swab. Place the soapy end of the cotton swab back in the middle of the milk and hold it there for a few seconds. Look at that burst of color!

5. Add another drop of soap to the tip of the cotton swab and try it again. Experiment with placing the cotton swab at different places in the milk. Notice that the colors in the milk continue to move even when the cotton swab is removed. What makes the food coloring in the milk move?

The science activities

•  stimulate children’s curiosity

• help children develop own understanding of the natural world

  • encourage children to be persistent problem solvers.
