Why do they need those skills?
For 2 of your words
Explain why a scientist needs that skill
e.G Observant – Scientists need to observe
because then they can see any changes
that happen in an experiment.
Why do they need those skills?
All scientists need to be able to
• Communicate with others
• Solve problems
• Think clearly
In order to do these they must use their
_________
Senses
• What are the senses?

Senses
SEEING uses your EYES
HEARING uses your EARS
TOUCH uses your HANDS
SMELL uses your NOSE
TASTE uses your TONGUE
And these are all linked to your BRAIN by
the NERVOUS system.
The Eye
• Sees the world upside down
The Ear
• Helps us to balance
The Skin
• Reacts to temperature, humidity, pain
The Nose
• Affects the taste too
The Tongue
• Has lots of taste buds
YOUR TASK
• Choose ONE of the senses and write a
journal reflecting on the job you perform
each day and how you help people to do
different things. (1 page)
• Example – My name is Terry the tongue
and I …….
YOUR TASK
• Design a rap song, song or a poem based
on the equipment you would find in the
laboratory and why it is so important to
use it safely.
• 6 – 8 lines.
Before we start…
• Before prac – playing it safe in the lab

• Matching game with equipment

Practical 4
Where does the sound come from?
All students close their eyes
Students to walk around the room
When a sound is heard student point in the
direction of sound
Volunteer will record results
Discuss
Basketball video
• Basketball
• Watch the video and count how many
times the white team passes the ball to
each other.
Observing - recording
• Draw a map of the laboratory
• Mark the safety equipment
• Mark on the lab equipment
Safety
Why do we have safety rules?
What rules do you know already?
Watch safety video
Design your own poster
Before we start..
Before we start every practical we need to
outline our AIM (What we hope to achieve)
and our HYPOTHESIS (what we think might
happen)
Title = Boiling Water Practical

Before we start…
Now we need to draw up a table for our
results

Time Taken (min/secs)
Lets get started
with….Laboratory Equipment
You must find and place on your desk:
• A beaker
• Safety goggles
• A heatproof mat
• A pencil/pen and our workbooks
• A measuring cylinder
• Bunsen Burner
• Gauze mat
• Tripod
• Boss
• Retort stand
Boiling Water Practical
Method
1. Put on safety goggles and apron
2. Set up your Bunsen burner as practiced
but leave burner UNLIT! (heat proof mat
under Bunsen, Bunsen attached to gas)
3. Measure out 20mls of water into your
beaker using your measuring cylinder
4. Light your Bunsen Burner then put tripod
and gauze mat ontop.
Boiling Water Prac (cont.)
5. Place beaker ontop of tripod (carefully)
and start stopwatch
6. Once water begins to bubble stop timing.
7. Attempt steps 1-6 three more times and
record the result in your table.
8. Draw a graph using the next slide as an
example.

So what happened?
Discussion
1. Why did we do this practical 3 times?
2. Did the time taken for the water to boil
vary? Why/why not?
3. What conclusions can you draw from
your results?
Conclusion?
Equipment – drawing and diagrams
Can you match them up?
Equipment – drawing and diagrams
Can you identify the equipment from it’s diagram?

Using a Bunsen burner
• Flame colours
• Safety
• Lighting the burner correctly
Practical write -ups
• Watch video
• Read through guidelines
What is needed in a write-up?
Graphs
List the types of graph that you know
Did you get
Bar chart
Line graph
Scatter graph
Choosing the right graph
In Science we nearly always use line graphs
to illustrate our findings.
Bar charts are used to show results from
surveys OR when data is not numerical
Scatter graphs are rarely used
Measuring devices
How many instruments can you
name that measure…
1. Time
2. Length
3. Mass

How could we test each of
these?
TASK
- Outline a practical (Aim and hypothesis) that
would allow data to be collected using each of these
measuring devices.
• E.g Time =
Aim – To measure the time it would take a human to
carry a washing machine 100m.
Hypothesis – The heavier the washing machine, the
greater the time taken to cover 100m.
How could we test it further?
TASK – for ONE of your outlined practical's,
design a materials list, method, predict
results (see me if confused!!) draw a graph
or table and write a conclusion to test your
practical.

universal units … SI units
