Beach

10. Bladderwrack (Seaweed)

Bladderwrack is a seaweed
that gets its energy from
sunlight, just like the
plants on the land. But
it is also very different.
The thick bladders are
filled with air to keep the
seaweed floating close to
the sunlight. Bladderwrack likes to live in shallow
areas of the sea, and it often ends up on the land
when the tide is low. Here you can easily find it
and study it. Important! Be careful when you are
looking for seaweed close to the sea. Low tide will
become high tide again! Always go with an adult.

11. Sand

Sand is made of many different types of grains.
On the beach much of the
sand is made of crushed
shells. Near rivers the
sand is mostly made of
crushed rock. On
volcanic islands the
sand is completely black.
Can you find sand from
different places, and tell them apart in the
Smartscope? Can you tell where each one came
from by looking at it?

12. Salt crystals

If you let seawater evaporate in your object holder,
it will leave behind salt
crystals. Have a look at the
crystals. How many
faces (flat sides) do they
have? If you're not near
a sea you can make your
own seawater by
dissolving a teaspoon of
salt in a glass of water.

At home

13. House flies

You will often find dead
houseflies on window sills
or under radiators.
Houseflies are fascinating
little aerobatic fliers. They
can fly in loops in the air, and they can
sit on the ceiling. Have a good look at the wing of
a housefly and uncover their flying secrets. Do you
see knobbed structures just behind the wings?
These are called the haleteres, and they are flight
stabilizers. Have a look at the legs of the fly. Can
you figure out how flies can stick to the ceiling?

14. Coins

At first glance, coins look
smooth and shiny. But if
you look at them under
a microscope you can
see many little nicks
and scratches from all
the many hands, pockets
and wallets the coin has
been in during its life. Can you see a difference
between coins of different ages? Coins are always
marked with the year in which they were minted
(created).

15. Magazines and newspapers

Pictures in magazines look to
us as if they have all the
same colors as the world
around us. But there are
no printing machines
that can print all the
colors of the world. They
only have black, and three
different colors! A printed image is made of
thousands of little dots of these colors, that are
combined in different ways to look like other
colors. Can you see which three colors are used?
