00-03263 Dynamo Torch

Turn a simple toy motor into a generator that converts hand

motion into electrical energy and powers a light bulb. No

battery, no pollution, just amazement. The generator could be

used as an awesome emergency torch. Caution: High Voltage

Inspiration & Fun!

00-03266 Soda Can Robug

Millions of soda can are wasted everyday. Help save our

environment. Recycle one of them and turn it into a cool robotic

bug. Switch it on and watch it vibrate causing it to slide across

the ﬂoor. It even emits a “buzz” as it moves along - just like a

real bug. It’s an awesome robotic science kit.

00-03267 Windmill Generator

Build this amazing wind generator and learn about renewable

energy. Watch the LED glow as it is powered by free energy from

the wind. No batteries required!

00-03279 Weather Station

This ultra smart weather station has many functions. You can

keep track of weather changes, learn facts about the weather

and do experiments on the green house effect. When you have

done exploring you can recycle a plastic bottle and make your

very own mini green house.

A. SAFETY MESSAGES

1. Please read all instructions before you start.

2. Adult assistance and supervision is recommended at all times.

3. This kit is intended for children aged over 8.

4. This kit and its ﬁnished product contain small parts which may cause a choking hazard if

misused. Not suitable for children under 3.

5. Do not use sewage water for the experiments. Sewage water contains bacteria and micro

organisms which will contaminate the kits. Follow the instructions to mix artiﬁcial “dirty

water”. This is sufﬁcient to demonstrate the purifying effects of the kit.

6. This is only an experimental kit for demonstrating different methods of purifying water. The

kit is not intended as a ﬁltering device for drinking water. Do not drink the water puriﬁed with

the kit. Some experiments involve hot water. Adult supervision is required.

B. CONTENTS

Remarks: some materials from home are also required. Ask an adult before using these.

C. EXPERIMENT 1 - FILTERING Warning: The filter column is not intended as a filtering device for drinking water. Do not drink the filtered water. Gravels In this experiment, you use the assembled filter column from the kit to purify water. The various filters in the column remove impurities from the water. You will need: 4 x filter sections, 4 x filter plugs, filter base, soft wax, bag of active carbon, bag of sand, bag of gravel, filter paper.
PAGE 3
How it works Each section of the filter column removes particles from the water, purifying it. The different filters remove particles of different sizes. The grains of sand and gravel have small spaces between them. These allow water to pass through, but trap particles in the water. The carbon granules are made from a material called active carbon. Chemicals in the water cling to the surface of the carbon and are removed from the water. This process is called adsorption.

D. EXPERIMENT 2 - DISTILLATION Warning: This experiment requires hot water. Adult assistance and supervision is required when handling hot water. In this experiment you purify water by a process called distillation. The water evaporates, leaving the impurities behind. Distillation is another common method of producing clean water. The method is commonly used in desalination plants. You will need: funnel-shaped collector, small plastic cup.

E. EXPERIMENT 3 - SOLAR PASTURIZATION Warning: The solar-heated water could reach a temperature of 60 degrees Celsius (149 degrees Fahrenheit) or more. Handle the heated water with care. Adult supervision is required. In this experiment you purify water by a process called solar pasteurization. When water is heated to 65 degrees Celsius (149 degrees Fahrenheit), dangerous micro-organisms in the water are killed. Heat from the Sun is used to heat the water to pasteurize it.
PAGE 6
How solar pasteurization works The reflectors are angled to converge and concentrate solar energy. The black plastic cup absorbs the energy, which heat up the water inside. The space in between the glass and cup works like double-glazing. The trapped layer of air inside insulates the cup, preventing too much heat loss. When water is heated to 65 degrees Celsius (149 degrees Fahrenheit) all the dangerous microorganisms in it are killed. Heating water to this temperature is called pasteurization.
