Top 10 Science Experiments For Kids 7 – 12

Top 10 science experiments for kids 7 – 12 years old are described in a simple language that includes materials needed, steps involved, and a discussion on theories behind them. Kids would love to build a Juice Rocket, an Electric Motor, and an Elephant Toothpaste and several other exciting experiments. With some help from parents this book makes learning a lot of fun for kids. It offers a perfect family activity without the cost of a summer camp.

Following is a complete list of top 10 science experiments from the book:

PHYSICS
Hovercraft,
Solar Cooker,
Electric Motor,
Rubber-band Racer

CHEMISTRY
Lemon Batter,
Juice Rocket,
Elephant Toothpaste

LIFE SCIENCES
Germinator,
Painting Flowers,
Straw Pulse Meter

Each of the top 10 experiments have following sections:
1. Goals
2. Description
3. Materials
4. Building Steps
5. Problem Solving
6. Discussion

and a lot of images showing materials and building steps.

Here is a sample Description for Electric Motor:

Electric motors convert electrical energy into mechanical energy. In other words they use battery or A/C power to spin a shaft which can then be used to move wheels on cars and trains, lift weight for elevators and cranes, or spin CDs and DVDs for players.

Motors have magnets with the same poles (north-north or south-south) positioned to repel each other. One of them is placed on a stationary part called “stator” and other one on the “rotor” which moves because stator’s magnet repels it. It can only move in a circular motion making it spin. To make the rotor spin continuously stator has an electro-magnet instead of a permanent magnet. When electric current flows through its coil, it turns magnetic and repels the permanent magnet on the rotor making it move.

And here is a sample Discussion from Juice Rocket:
