And metel rust in a boat

Fire

Medicine

When stomach acids bubble

When you mix baking soda with vinegar

By Joao:

The rusting of metal

During cooking(eg. Yeast)

When we create fires

During science practicals in experiments

In our stomach

1. In the kitchen: When you bake a cake, the baking powder reacts with heat and makes the cake rise.

• 2. In our bodies: When we eat food, our body digests it using chemical reactions.

  3. When something burns: Burning wood or paper is a chemical reaction that produces heat and light.

  4.Rusting: When iron gets wet and reacts with oxygen, it forms rust.

2. Water and metal turns into rust.

3.Opening a fizzy drink.

4.Coke and mentos.

.Washing with bleach

.when metal rusts

2.When baking a cake

.using baking soda

.Microwaving popcorn

When:

1.cooking food

2.rusting iron

3.burning a candle

4.digestion

5.breathing

2.Water and metal(some metals get rusted due to the water )

3.Baking cakes (yeast helps dough rise)

1. In the kitchen – Cooking involves chemical reactions (e.g., baking a cake, browning meat, boiling an egg).

2. In your body – Digestion,even thinking

3. In nature . Plants use photosynthesis

4. In cleaning .using bleach to clean surfaces.

5. In transportation .Car engines burn , a chemical reaction .

Boiling Water

Digestion in my stomach

Breathing oxygen and breathing out carbon dioxide.

2. when the iron crockery touches water and becomes rusty

3. In the air when we breathe oxygen and breathe out the carbon dioxide

2. when you mix vinegar and baking soda that makes a reaction to the particle in baking soda

3. When you put mentos in coke bottle in fizz’s up and it explodes like a volcano.

Baking soda

Using Bleach

Baking a cake

When we’re cooking or baking

1.When iron reacts with water it becomes rusty.

2.Baking soda reacting with vinegar creates a chemical reaction

1. Baking a cake, Whem my mother makes cake, baking powder or soda reacts to release gas, making the cake fluffy.

2. Rusting of iron, When iron nails are exposed to air and water, they form rust. I see them on drawers.

3. Burning a candle, When I light a wax reacts with oxygen to produce heat and light.

4. Using vinegar and baking soda, I think they react to form bubbles of carbon dioxide gas.

   
   

Photosynthesis:transform light into energy.

Rusting:when you put oxygen Rusting is caused.

Cooking:uses heat to change chemically.

Soap with detergent: they both clean by causing chemical reactions.

Gas production: when water boils itturns into gas.

• We will see chemical reactions when cooking or baking something at home.

• We will see chemical reactions outside when burning something like ashes or coal and water.

Rusty metal

•When cooking

•Metal rust

Mostly cooking food

When u put iron into water

When u put mentos into soda it starts fizzing up and flows out of the bottle

Putting lemon juice into water

.Baking a cake and the batter rising

.Rusting of iron

.Coca Cola And Mentos

.Orange juice

.Lemon juice

Cooking!

Soda and Mentos!

Butter melting!

Vinegar!

Rusting of iron: Iron turns reddish-brown when left in water and air.

Baking a cake: The cake rises and changes texture

In the kitchen for example when you’re baking something in the kitchen for example bread, cake, lemon juice, and many more.Also a fun one you can do is put mentos into a coke…

2.Mentos in coke

3.Baking a cake

4.Cooking a egg

5.Boiling some water

Rising bread

Cooking oil

Butter melting

Baking cake

Mentos in soda

Rusting in the water!

rising bread

orange juice

lemonade

burnt cake

boiling water

Metal rusting in water

Volcanic eruption

Coca Cola and mentos

when you melt butter

when you cook

and boiling water

Identify a reaction in your kitchen

ANS:when you bake batter in the oven

What about in the environment?

ANS: when water rusts metal when exposed to moisture for too long.

By Rehan

Mentos and cola

Metal and water

A chemical reaction happens when substances break and form bonds, creating new substances. Examples include rusting iron, burning wood, baking, vinegar and baking soda, and photosynthesis—each causing changes like gas formation, color shifts, or energy release. These reactions drive natural and industrial processes.
