Test Tube Holder | Holds test tubes when heating or transporting them. |
Test Tube Brush | Cleans the inside of test tubes and other narrow glassware. |
Scoopula | A small spatula-like tool used to transfer solid chemicals. |
Forceps | Tweezer-like tools used to handle small objects or specimens. |
Medicine Dropper | Dispenses small amounts of liquid, drop by drop. |
Test Tube Rack | Holds multiple test tubes upright for storage or during experiments. |
π‘οΈ Heating and Support Equipment
Tool | Usage |
---|---|
Thermometer | Measures temperature of liquids, gases, or solids. |
Glass Stirring Rod | Used to mix chemicals and liquids manually. |
Bunsen Burner | Provides a flame for heating substances in the lab. |

π± Parts of a Plant β A Fun and Educational Guide for Kids
Plants are living things that grow in soil, need sunlight and water, and help make the world green and beautiful. But did you know that every plant has special parts that do important jobs? Letβs explore the main parts of a plant, what they look like, and how they help the plant grow and stay healthy.
πΏ 1. Roots β The Underground Helpers
-
Location: Found underground
-
Job: Roots hold the plant in place and absorb water and nutrients from the soil.
-
Fun Fact: Some roots store food, like carrots and sweet potatoes!
πΎ 2. Stem β The Plantβs Support System
-
Location: Above the ground, connecting roots to leaves and flowers
-
Job: The stem supports the plant and carries water and nutrients from the roots to other parts.
-
Fun Fact: Stems can be soft like a flowerβs or hard like a tree trunk!
π 3. Leaves β The Food Factories
-
Location: Attached to the stem
-
Job: Leaves use sunlight, air, and water to make food for the plant through a process called photosynthesis.
-
Fun Fact: Leaves come in many shapes and sizes β some are even used as food, like spinach!
πΈ 4. Flowers β The Colorful Reproducers
-
Location: At the top or sides of the plant
-
Job: Flowers help plants make seeds so new plants can grow.
-
Fun Fact: Flowers attract bees and butterflies with their bright colors and sweet smells!
π₯ 5. Fruits β The Seed Protectors
-
Location: Grows from the flower after pollination
-
Job: Fruits hold and protect seeds until theyβre ready to grow into new plants.
-
Fun Fact: Apples, bananas, and tomatoes are all fruits β even if some people think theyβre vegetables!
π° 6. Seeds β The Baby Plants
-
Location: Inside fruits or flowers
-
Job: Seeds grow into new plants when theyβre planted in soil and given water and sunlight.
-
Fun Fact: Every seed contains a tiny plant waiting to grow!
π― Why Learning Plant Parts Matters
-
Helps kids understand how plants grow and survive
-
Builds vocabulary and science knowledge
-
Encourages curiosity about nature and gardening
-
Supports early learning in biology and environmental science

Earth holds about 326 million trillion gallons of water, covering approximately 71% of the planetβs surface. Most of this water is saltwater found in oceans, while only a small fraction is freshwater available for human use.
π How Much Water Is There on Earth? A Deep Dive into Our Planetβs Liquid Treasure
Water is one of the most essential elements for life on Earth. It shapes our landscapes, supports ecosystems, and sustains human civilization. But just how much water does our planet actually hold β and where is it located?
π§ Total Volume of Water on Earth
According to the U.S. Geological Survey and other scientific sources, Earth contains approximately 326 million trillion gallons of water, or 1.332 billion cubic kilometers. If all the water were gathered into a single sphere, it would be about 860 miles (1,385 kilometers) wide β roughly the distance from Manila to Hong Kong.
π Where Is Earthβs Water Found?
Water exists in various forms and locations across the planet:
Source | Percentage of Total Water | Type |
---|---|---|
Oceans | 97.2% | Saltwater |
Glaciers & Ice Caps | 2.15% | Frozen freshwater |
Groundwater | 0.61% | Mostly freshwater |
Lakes & Rivers | 0.009% | Freshwater |
Atmosphere | 0.001% | Water vapor |
Biological Water | Trace amounts | In plants & animals |
Sources:
π§ Freshwater: A Precious Minority
Although water is abundant, only about 2.5% of it is freshwater, and less than 1% is accessible for drinking, agriculture, and sanitation. Most freshwater is locked away in glaciers, polar ice caps, or deep underground aquifers.
π¦οΈ Water in the Air and Living Things
Water also exists in the atmosphere as vapor, forming clouds and driving the water cycle. Additionally, water is found inside all living organisms β including humans, who are made up of about 60% water.
π Why Understanding Water Distribution Matters
Knowing where water is and how much is available helps us:
-
Manage water resources sustainably
-
Protect ecosystems and biodiversity
-
Prepare for climate change and droughts
-
Educate future generations about conservation
π§ Fun Fact:
If you could collect all the water on Earth into a giant ball, it would be smaller than the Moon β but powerful enough to shape continents and support every living thing!
