In this experiment you will extract DNA from the cells of strawberries using a home made extraction kit. The experiment is perfect for any young scientist and introduces the concept of DNA extraction with in-depth explanation of the hands-on scientific procedure. All materials and equipment are inexpensive, easy to find and safe to use at home.
One of the most fun experiments that can be performed at home! Ferrofluid is a magnetic liquid that takes the shape of the magnetic field applied to it and can be used to visualize magnetic fields. This experimental explains how a ferrofluid can be made multiple ways by using simple household items.
Make your own homemade pH indicator! Red cabbage juice contains a pH indicator that exhibits a wide range of colours according to the acidity of the solution. This experimental contains in-depth scientific explanation of why certain compounds are coloured and how the colour change occurs. All materials and equipment can be found at home and are relatively safe to use.
A cloud chamber, also known as the Wilson chamber, is a device which makes visible the paths of charged particles emitted as a result of radioactive decay. A very simplified version of the cloud chamber called a “diffusion cloud chamber” can be constructed at schools from available scientific supply companies. This experiment is perfect for teteaching students about radioactive decay and ionising radiation.
In this experiment, you will use a flame test to visually determine the identity of a metal or metalloid ion, based on the colour it turns a flame. This is because each element has an exactly-defined emission spectrum, which scientists can use to identify them. For example, lithium produces a red flame and sodium a yellow flame. This experiment can be performed at home, but must be done under the supervision of a responsible adult.
Using a £10 laser and a syringe you can magnify a water sample 1000s of times over at home. Using this method you will be able to projected on your wall single cell creatures, modketos lave, microscopic worms, etc. This experiment is easy to set up and perform at home and is perfect for a school science projects. The picture below is a 5mm mosquito larvae projected to be 3m long using this method.
You can make at home a simple pulse jet engine that works on the same principle as the engine that propelled the V-1 flying bomb in the second world war. The experiment is perfect to explain pressure differences, flash points and combustion. It is also loud, exciting and potentially dangerous making it perfect for school demonstrations when carried out safely. The pulse jet is also historically interesting and leads onto rocket technology and the space rase.
