4. Numbered heads together. Name the three smallest living things
and the three biggest non-living things that you can imagine.

5. - All living things are made up of cells.
- Cells are the basic units of life.

microscopes.

10. 2
- Reproduction is the basic life process that living things have to
create new organisms similar to themselves.
Dictation.
11. 2
- We are multicellular living things and our cells work together at
different levels. They are levels of organization.
Dictation.
12. 2
1-2-group. Look and match from the simplest to the most
complex level of organization.
13. 2
Work in group. Watch the video and draw your group
coordinator’s levels of organization. Make his/her nervous system to do it.
Neuron

ear
skin
tongue
eye

16. 3
Work in groups. Read cooperatively, draw each sense organ,
write some information and complete the nervous system poster.
- Sight: The eyes are the sense organs of
sight. They detect light so we can see
shapes and colours. We also estimate
distances.
The receptors are in the retina and the
information travels through the optic
nerve.
- Hearing: The ears are the sense organs
of hearing. They detect sounds, their
properties and where they come from.
The receptors are in the cochlea and
the information travels through the
auditory nerve.
17. 3
- Touch: The skin is the sense organ of touch. It
detects temperature, pain, pressure…
The receptors are the touch receptors and the
information travels through the nerves.
- Taste: The tongue is the sense organ
of taste. It detects different flavours.
The receptors are in the taste buds
and the information travels through
the taste nerves.
- Smell: The nose is the sense organ of
smell. It detects different smells in the air.
The receptors are in the olfactory
epithelium and the information travels
through the olfactory nerves.
19. 3
- The information goes from the receptors to the brain. The brain
interprets the information.
Dictation.
Work in groups. Use your posters to prepare a 3-minute
exposition. Everybody must participate.

21. 4
Look at the parts of the nervous system. Memorize them in one
minute and play ‘Simon Says’.
22. 4
It receives and interprets information from external and
internal environment (stimuli).
It gives you energy from food.
It supports and protects your body.
It gives orders for your body to respond to stimuli.
It controls and coordinates all organs and systems in your
body.
It is a dwarf planet and moves around the Sun.
Work in pairs. Read cooperatively and tick ( ) the 3 tasks of the
nervous system.
23. 4
One member of each group is going to draw a nervous
tissue on the board using a lot of neurons.

- Later, another member is going to label as many dendrites,
bodies and axons as possible in one minute.

- Finally, other members are going to hear some stimuli and
move their fingers (information) from the correct receptor to the
brain.

Nerves
a. It controls movement, coordination and balance.
b. They receive stimuli from the receptors in the
sense organs and send them to the central nervous
system.
c. They send orders from the central nervous
system to others organs.
d. It controls voluntary actions (running, talking…),
stores data and memories, processes thoughts and
controls emotions.
e. It controls internal organs and we don’t need to
think about them (heart and breathing).
f. It produces involuntary responses, for example
when you move your hand away from hot objects.
It’s protected by the spinal column.

Work in groups. Watch this video, look at this diagram and
make a few cards with stimuli and other cards with their appropriate
responses. Then, play a matching game.

Work in groups. Watch this video, look at this diagram and
make a few cards with stimuli and other cards with their appropriate
responses. Then, play a matching game.
Watch this video and
write five examples of reflexes
and learned reactions.
30. 5
A lot of processes are occurring inside our body at all times,
for example, digestion and blood circulation. These processes
are coordinated in order for the body to function properly. This
is called internal coordination. The nervous system is responsible
for the internal coordination.
a. We voluntarily move our stomach. __
b. Breathing is controlled by internal
coordination. __
c. If internal coordination doesn’t work,
we have a problem. __
d. Walking, speaking and writing are
controlled by internal coordination. __
Read cooperatively and write T (true) or F (false).
