Explain in your own words how the sense of sight works . 1
Our sight
2
We can see because our brain interprets the information it receives from our eyes . First, the eyes capture an image from the outside world .
Then, the eyes convert this information into nerve impulses . Nerve impulses are small electric currents than run through our nerves .
After that, the nerves carry this information to the brain .
Finally, the brain receives and interprets this information . This is how we see .
Sometimes the brain interprets the information it receives from the eyes in a different way . This produces an optical illusion: we see something differently from reality . An optical illusion is not real .

Get moving!

Some animals stay in one place all their lives . They do not move . For example, sponges and barnacles live attached to rocks . However, most animals can move around,
and they do it in different ways .
Birds, bats and insects fly . Lizards and crocodiles crawl .
Fish, whales and sea turtles swim . Humans, ostriches and mice walk .
Snakes slither .
Animals move at different speeds . Walking at a normal pace, human beings usually walk five or six kilometres per hour . Some animals can travel in one hour a distance that takes other animals a whole year! Here are some examples:

During the winter, the days get shorter
and the temperatures drop . So, animals need to protect themselves from the cold .
Some animals, such as rabbits, dogs, cats and polar bears, grow thicker fur to keep them warm .
Some animals hibernate . This means they sleep during the coldest months of the year . For example, squirrels, bears, turtles, bats and frogs hibernate and sleep all winter .
Some animals migrate . This means they travel long distances to find warmer climates . For example, storks, antelopes, whales, swallows and ducks migrate .

What does cephalopod mean?
Are cephalopods vertebrates or invertebrates? Explain .
Are all marine animals invertebrates? Explain .
Name three other animals that can swim . 1
Cephalopods are animals such as squids, octopuses and cuttlefish . These sea creatures are unusual because their feet, which are actually long tentacles, surround their mouth and are attached to their heads . Cephalopod means head-foot .
Did you know that the octopus is one of the most intelligent of all the invertebrates in the marine world? Octopuses also have excellent eyesight, although they cannot hear .
An octopus’s soft body looks like a large bag . It lives on the ocean floor, and its eight tentacles help it to move about and catch food . An octopus moves by jet propulsion: it sucks water in then squirts it out of its head so fast that it moves through the water!
Octopuses protect themselves in two ways . They squirt dark ink which blinds their enemies and gives them time to escape . They also change the colour of their skin so that they blend in with their surroundings . This helps them hide from their enemies .

made of solid wood . Wheels with spokes were invented over 1,000 years later .
Later, wheels were made of metal . This allowed heavy objects to be moved from one place to another .
After that, metal wheels were covered with rubber and cork . These wheels are still used today because they are so light and resilient .

How does drinking
water get to our homes?
River water collects in reservoirs . This water is not clean and it is not safe to drink .
First, this water goes to treatment plants through pipes . Here it is cleaned of impurities .
Once it is safe to drink, this water is distributed to homes through pipes .
Used water from our homes is collected through a network of sewers . Then it flows to treatment plants to be cleaned of impurities again .
Finally, the treated water goes back into rivers . Sometimes, it is recycled and used for watering parks and gardens .
Answer the questions.
Where is river water collected?
