A species is a group of living things that are very similar and can produce young (offspring) together.
Examples:
All dogs belong to the same species.
All cats belong to another species.
Humans are one species called Homo sapiens.
For example:
Chocolate is not always bad. Eating a small amount can be okay. But eating too much chocolate can cause problems:
Lots of sugar – Too much sugar can lead to tooth cavities and weight gain.
Less healthy food – If you eat a lot of chocolate, you may not feel hungry for healthy foods like fruits and vegetables.
Too much caffeine – Some chocolates contain caffeine, which can make it harder to sleep.
Stomach problems – Eating a lot at once can sometimes cause a stomach ache.
Energy crashes – Sugar gives quick energy, but later you may feel tired.
A volcano eruption happens when hot melted rock called magma rises from deep inside the Earth and comes out through an opening in the ground.
How a volcano erupts
Deep inside Earth, rocks melt and form magma.
Magma collects in a magma chamber.
Pressure builds up.
The magma pushes upward through cracks.
Chameleons change color using special cells in their skin called chromatophores.
Chameleons have layers of special cells under their skin.
These cells contain different pigments and tiny crystals.
When the chameleon is excited, scared, angry, cold, or trying to communicate, the cells change.
Light reflects differently from the skin, making the chameleon appear different colors.
How do chameleons control the changes? When do they know which colour to camouflage with? Does changing colours have anything to do with mating, do they attract females by changing colours?
Chocolate contains glucose (the same energy molecules we gain by eating food like fruits and vegetables), so if chocolate contains glucose isnt chocolate good for our health and essential?
