Fun Experiment: Exploring the Magic of Sounds
Sound Experiment – Clanging coathangers
How about a clanging coathanger sound experiment? The cool thing about this experiment is that it really helps children understand how sounds work!
What is a clanger?
Read more: Fun Experiment: Exploring the Magic of SoundsA clanger is a simple instrument that makes a clanging sound by banging two objects together.
You can make one with two coat hangers, some string, and some tape.
So what is sound?
In case you’ve ever wondered what that sound is, its the sound of thousands of different pitched materials vibrating against each other at once
Sound can be described as vibrations that travel through the air or another medium and can be heard when they reach a person’s or animal’s ear. Sounds create vibrations. For you to hear them, an object has to vibrate in the medium (solid, liquid or gas) that is around it. The medium vibrates and transfers this movement to the air. The air then moves your ear drum which sends the signals through your brain that you actually hear. This all happens within about one second.
Sound changes depending on how fast or slow an object vibrates to make sound waves. Pitch is the quality of a sound i.e. high or low and depends on the speed of the vibrations. Different materials produce different pitches; if an object vibrates quickly we hear a high-pitched sound, and if an object vibrates slowly we hear a low-pitched sound. Sounds are usually a mixture of lots of different kinds of sound waves.
Thus, when you raise and lower your clanger it should make a low and high-pitched sound as you hit different parts of the hanger against the table.
In conclusion, this equipment looks a bit basic but doing this experiment is an almost magical experience and a phenomenal way to get children thinking about sounds!
The wonders of slime
There is a wonderfully slimy hobby you can take part in as well as learn many scientific concepts along the way. It’s called slime-making. You may be surprised to learn that slime has many practical uses beyond its fun form.
Making slime is a great way to have fun with science. Not only can you make several types of slime, but you can also learn while you play. Would you like to know how?
First, what is slime?
Slime is a thick and slippery liquid substance.
Slime is normally made from non-toxic substances and is primarily green in colour.
Uses in Nature
Slime has a number of uses. Here are some amazing ways slime can be used by humans.
Slime in a naturally occurring setting has many practical uses. For example, algae is icky and sticky yet is an essential element of an ecosystem.
And in mucus, for respiratory health. Mucus has an important role in your lung’s immune response because it traps irritants in your airways and helps allow your body to expel them through coughing. This helps protect you from infection.
In snails and slugs, slime is a kind of mucus (an external bodily secretion) that they produce.
In both slugs and snails, slime is used as natural protection from the sun’s rays, bacteria, and cuts. Its protective and regenerative properties have even led to its use as an ingredient in skin care treatments for humans.
Slime is a fun and colorful way to have fun. It’s a wonderful way to play, bond with friends and family, and can brighten up a dull day. Just remember to clean it up after!
Heat Sources
One of the most important types of energy on Earth is heat energy. Heat energy is always being moved from one material to another. Heat energy always moves from the hotter material to the colder material.  When you hold ice, it might feel like the coldness is moving up your hand, but it’s actually the other way around—the heat of your body moves to the ice, which results in the ice melting.
A great deal of heat energy comes from the Sun’s light hitting Earth.
Other sources include:
Jiko (charcoal burner
Gas cooker
Ethanol cooker
Kerosene Stove
Three stones

Exploring parts of a simple plant
Plants are living things that grow from the soil and turn light from the Sun into food. Plants can be big or small. The parts of a plant include seeds, leaves, roots, the stem and flowers. There are different kinds of plants, but they all begin in the same way….
As a seed.
Plants have the following features:
Plants have roots
Plants have stems
Plants have leaves
Plants need soil to grow
Plants need sunlight to grow
Plants need water to grow
Plants make their own food using sunlight and water
Here’s a simple activity for you. Can you name the parts of this plant?
Have you finished….?
Good job!
Let’s see if you got it right.
