Candle Experiment

This experiment helps us observe the role of oxygen in burning.

Materials for this experiment:

A candle, a glass cup and a lighter.

Firstly, light the candle. Then turn the glass cup upside-down and put it on the candle. After a few minutes, you can see the candle slowly goes out.

Result:

Candle uses the oxygen around it while burning. When the cup is placed over the candle, no oxygen cam enter the cup, so the burning stops and candle goes out. This experiment shows that oxygen is necessary for burning. This experiment is simple, fun and educational!

I did a balloon experiment with vinegar and baking soda.

First, I put vinegar in a bottle. Then, I added baking soda into a balloon.

When I mixed them, a gas formed and the balloon got bigger.

It was fun and interesting.

I did a simple science experiment.

I used vinegar and baking soda.

When I mixed them, a gas called carbon dioxide filled the balloon.

I learned that a chemical reaction can make gas.

It was easy and fun.

The experiment works due to refraction of light. Light passes through air, glass, and water, changing direction. The glass of water acts like a lens, flipping the image. As a result, the arrow drawn on the paper appears to reverse direction when viewed through the glass. (Anghel Ioan-Adrian)

Volcanic Eruption Experiment
I did an experiment using baking soda, food coloring, and vinegar. First, I added the food coloring, then the baking soda, and finally the vinegar. This creates carbon dioxide gas, which makes the bubbles.I called this experiment a ‘volcanic eruption experiment’ because it looks like a volcano erupting.

Experiment – Red Lava
This experiment shows a chemical reaction.
I mix baking soda, vinegar, and red food coloring to make a fun eruption.
The baking soda (a base) reacts with vinegar (an acid) to produce carbon dioxide gas, which makes the bubbles and eruption.
The red color makes the “lava” bright and colorful.
It is very fun to watch!

Experiment
I put black pepper in water. The black pepper stayed on the surface.
Then I dipped a cotton swab in soap and touched the water.
The black pepper moved to the sides.

Why
Soap changes the water’s surface tension, so the black pepper moves away.

My Opinion
The experiment was very fun, and I was very surprised.

I conducted a simple experiment to observe which materials float or sink in water. I used three glasses and tested small pieces of wood, stones, and plastic straws. First, I placed the stones in the water, and they sank to the bottom. Then, I added the plastic straws, and they floated on the surface. Finally, I put the pieces of wood into the glasses, and they also floated. Based on my observations, I concluded that stones sink because they are denser than water, while plastic straws and wood float because they are less dense.

Experiment: Dissolving Sugar in Hot and Cold Water

In this experiment, we see how sugar dissolves in hot and cold water.
We take two glasses, one with hot water and one with cold water. We add the same sugar to both and stir.
We notice that sugar disappears faster in hot water. This happens because hot water moves faster, helping the sugar mix quickly.
So, warmer water makes sugar dissolve faster.

Experiment: Dissolving Sugar in Hot and Cold Water

In this experiment, we compare how sugar dissolves in hot water and cold water.

First, we take two glasses. One is filled with hot water and the other with cold water. Then, we add the same amount of sugar to both glasses and stir them equally.

We observe that sugar dissolves faster in hot water than in cold water. This is because the molecules in hot water move faster, which helps the sugar break down and mix more quickly.

In conclusion, temperature affects the rate of dissolving. Higher temperature makes substances dissolve faster.

Candle Experiment
The candle burned brightly at first, but when covered with an upside-down glass jar, it quickly flickered and went out. This happened because the flame used up all the oxygen trapped inside the jar, and without oxygen, fire cannot continue to burn.

Red Cabbage Experiment (Acid-Base Indicator)

Purpose of the experiment: This experiment demonstrates how chemical substances change color according to their pH value. Materials used: Red cabbage, hot water, clear glasses, lemon juice, baking soda, vinegar, dishwashing liquid.

Instructions: Chop the red cabbage and let it sit in hot water for 15 minutes to obtain a dark purple liquid. Pour this purple liquid over glasses containing different chemical substances (lemon juice, baking soda water, etc.).

Result of the experiment: Each substance has a different pH value. Therefore, they all turned different colors. Substances with a pH value between 0-7 (Acids) are red or pinkish, while those with a pH value between 7-14 (Bases) are blue or greenish.

🧪 Our Simple Science Experiment: Finding the Density of an Irregular Object

# data[].attributes.body
As part of our "17-21 April: Experiment Padlet Completion" task, our students became little scientists! In this video, our students practically demonstrated how to calculate the density of an irregularly shaped object.

How did we do it?

Step 1: First, we measured the mass of our object using an equal-arm balance and found it to be 200 grams (g).

Step 2: To find the volume of the object, we dropped it into a graduated cylinder filled with water. Based on the amount of displaced water, we measured its volume as 200 milliliters (ml).

Step 3: We used one of the basic formulas of science: "Density = Mass / Volume". By calculating 200 g / 200 ml, we found the density of our object to be 1 g/ml.

Through this experiment, our students successfully transformed their theoretical science and math knowledge into a real-life problem-solving skill!

We lit a candle. Then we poured two tablespoons of baking soda into a glass of vinegar. We waited for it to settle at the bottom because it was heavier, then we placed the lit candle in the glass, We lit a candle. Then we poured two tablespoons of baking soda into a glass of vinegar. The reaction created a lot of foam and released carbon dioxide. We waited for it to settle at the bottom because it was heavier, then we placed the lit candle in the glass, being careful not to get it wet.
The candle went out because the invisible gas (CO2) reduced the amount of oxygen in the glass being careful not to get it wet.

First, put a balloon over the mouth of a bottle.

Then place the bottle in hot water. The balloon starts to inflate.

After that, place the bottle in cold water. The balloon deflates.

Explanation:

When the air inside the bottle is heated, it expands and fills the balloon.

When it cools down, the air contracts, so the balloon shrinks.
