How ACIDIC is the water? And how about soil? Examine the acidity of the soil or water in your area using some magical RED CABBAGE

Acid meter

Let’s examine how much PARTICULATE MATTER is in the air. Tiny particles are floating in the air. We do not see them, but breathe them every day. Make a simple measuring device using a MILK CARTON and VASELINE

Particulates meter

You’ll be investigating the SOIL in your area. There are millions of microorganisms, tiny fungi and bacteria called MICROBES, in the ground beneath you and they can function as a BATTERY!

Microbes meter

Investigate NOISE POLLUTION in your area. Where is it QUIET and where is it TOO LOUD? Is the screaming on the playground too noisy? Maybe it’s your sister’s violin lesson? Use a simple smartphone APP to measure it.

Ever heard of the GREENHOUSE EFFECT? Your farts contain something called METHANE GAS (CH4), which is a GREENHOUSE GAS! But Cows are the biggest offenders to our planet. Build a fart-o-meter using custom electronics.

The sun is our friend, but some of its LIGHT can’t be seen with the human eye . For example, ultraviolet light (UV radiation) which, by the way, is NOT GOOD for humans. Use a chemistry experiment to reveal invisible light.

UV-radiation meter

If water doesn’t let through enough light, it becomes difficult for plants and animals to live in. Build your own water clarity meter using an old record (LP, ask granddad!) and a piece of rope.

TREES and PLANTS are both beautiful and VERY USEFUL! They contribute to a pleasant CLIMATE in urban areas. Take a look at our world from ABOVE using a KITE to measure the amount of GREENERY growing in you area.

In almost all WATER, you can find MINERALS. Salt, for instance, is a mineral and the sea is full of it. Living ORGANISMS need minerals, but you can have TOO MUCH of a good thing. Build a water measuring device by using ELECTRICAL current from a BATTERY.
