Experiments Demonstrating Physical Reactions

The video features a series of fun science experiments for kids. It starts with a hand boiler to test body heat, followed by a color-changing Ulala paper and an energy stick circuit. The fortune teller fish experiment demonstrates moisture detection. A love potion is created using phenolphthalein, and magic beans are used to make a color-changing bracelet. Finally, jelly marbles are grown to demonstrate absorption and color change.

What does the hand boiler experiment demonstrate?

• The effect of cold temperatures on liquids

• The freezing point of liquids

• How liquids react to heat from the body

• The boiling point of water

What happens to the Ulala paper when you place your hand on it?

• It becomes transparent

• It changes color due to temperature change

• It remains unchanged

• It emits a sound

How does the energy stick work?

• By using magnetic fields

• By completing an electrical circuit

• By absorbing sound waves

• By using solar power

What does it mean if the fortune-teller fish curls its head and tail?

• You are in love

• You are angry

• You are jealous

• You are indifferent

What causes the love potion to change color?

• Exposure to sunlight

• A reaction between an acid and a base

• Mixing with water

• Heating it up

What happens to the beads when exposed to sunlight?

• They emit light

• They dissolve

• They change color

• They shrink

What is the purpose of the jelly marbles experiment?

• To demonstrate evaporation

• To show how objects can grow in size

• To illustrate the concept of density

• To measure the speed of absorption

What color do the jelly marbles turn after absorbing the colored water?

• They turn white

• They take on the color of the water

• They turn black

• They remain clear

What is the main takeaway from the jelly marbles experiment?

• Jelly marbles are unaffected by water

• Jelly marbles can change color and size

• Jelly marbles can dissolve in water

• Jelly marbles can float on water

What is the final message of the video?

• To continue experimenting and learning

• To stop watching science videos

• To avoid using science in daily life

• To only watch videos about animals
