Online Science Tutor

Science is the organized knowledge that includes a systematic and logical study of the natural world and how it operates. It is based on empirical evidence and is designed to be challenged by research. Our online science tutors help students at all skill levels, from the basics to mastering tough concepts and provides homework help. Our expert science tutors cover Earth Science, Biology, Chemistry and Physics.

The Nature of Science

The term Science comes from the Latin word, ‘scientia’, which means ‘knowledge’. It is not just about laboratories, microscopes, space shuttles etc. Explained in a simple way, Science is everything that you see around you, both living and nonliving. It tells us how things in the universe work.

1. Understanding Science
2. Scientific Data
3. Working Scientifically

The World of Living Things

We are surrounded by organisms of every size and shape. The world of living things is vivid and diverse. This branch of Science that studies living things, is called Biology. Living things range from the lowest and smallest organisms to the highly evolved plants, animals and human beings.

1. Classifying Living Things
2. Living Things and their Habitats
3. Adaptations

The Structure of Living Things

Have you ever wondered what we are made of? When you build a house, you use bricks of different shapes and sizes for each area of the house. Living things too are made up of bricks called Cells, which are unique to that particular type of organism. For example, a plant body will have only plant cells and an animal body, only animal cells.

2. Cells to Organisms
3. Plant Structure
4. Animal Structure

Human Body Systems

Ever been inside a factory? It is marvelous to see the machines working in coordination. What happens inside the human body is somewhat similar to it. Here organs and organ systems replace the machines and they work hand in hand like best friends.

1. The Human Body
2. The Digestive System
3. The Respiratory System
4. The Circulatory System
5. The Excretory System

Life Cycles and Reproduction

Each living being follows a particular growth pattern. Some stages are similar whereas others may be unique to each group of organisms. Even producing young ones is different in each organism. Let’s look at the details.

1. Life Cycle of Plants and Animals
2. Plant Reproduction
3. Animal Reproduction

Ecosystems

We are all part of a family and the place we live in is called home. Close your eyes and imagine the world as a home. Now your family includes all the living things that surround you. This new home can be called an Ecosystem. Let’s learn more about our Ecosystem.

1. Understanding Ecosystems
2. Energy Transfer in Ecosystems

Matter and Change

What is Matter? Is it anything that matters? Actually it is. When we say that everything around us is Science, each object or component of Science is called Matter. All things whether living or nonliving are made up of Matter. Let’s find out what Matter is composed of.

1. Atoms, Molecules and Compounds
2. Elements and their Properties
3. Changes in Matter

Matter and Energy

Are Energy and Matter connected? Scientists say that Matter can neither be created nor destroyed. It can only change to another form. Energy too has the same characteristic feature. So what are the different forms of Energy that we see in everyday life? Come, let’s learn.

1. Sound
2. Light and Heat
3. Electricity

Forces

A Force is nothing but a push or a pull. When we need to do some work or move something, we exert a force. Force is almost always connected with movement. Find out more about this relationship.

1. Forces and Motion
2. Simple Machines

Earth and Space

The Earth is the most beautiful planet in our Solar System, with its mountains, valleys and water bodies. It could be sunny or cloudy, raining or snowing – the seasonal changes in weather. How does all this happen? Find out here.

1. Rock Cycle
2. Water Cycle
3. Changes in Weather
4. Planets and Other Bodies in Space
