3. 1. INTRODUCTION
Everything has an origin. Objects that
we use are made out of different kind
of matter and materials.
In this unit we are going to see the
ways we find matter in our everyday
life, characteristics of different
materials and how can we save
materials by recycling.
4. 2. PROCESS
This is an individual work.
1. You need to see “UNIT 9: MATTER AND
MATERIALS” power point.
2. Do the activities proposed for:
• Matter states
• Materials
• Recycling
3. Send by e-mail or give to me in a paper the
answers to the questions asked.
4. Ask me (in class, e-mail, blog) any questions
related to the activities or contents.
5. 3. ACTIVITIES AND RESOURCES
MATTER STATES
1. Choose 1 experiment from the experiments slides. Do it and answer
the questions.
2. Do the games in these websites:
• http://www.sciencekids.co.nz/gamesactivities/gases.html
• http://www.sciencekids.co.nz/gamesactivities/statematerials.html
• http://www.sciencekids.co.nz/gamesactivities/detectivescience/statesofmatter.html
3. Make an outline about matter states and their changes.
6. MATTER STATES: EXPERIMENTS
WATER MOLECULES ON
THE MOVE
You need:
• A glass with hot water
• A glass with cold water
• Food colouring
Process:
• Put both glasses together on a
table.
• Put one drop of colouring in both
glasses.
• Watch carefully.
QUESTIONS
1. Where does colorant move
faster?
2. Why do you think this
happens?
3. What do you have to do to
change water into steam?
4. Where do molecules have
more space between each
other: in solids, liquids or
gases?
5. Where do molecules move
faster?
7. MATTER STATES: EXPERIMENTS
MELTING CHOCOLATE
You need:
• Small pieces of chocolate, all the
same size.
• Paper plates.
• Paper and pencil to record your
results.
Process:
• Put a piece of chocolate in a paper
plate in the SHADE. Record how
long does it take for chocolate to
melt or get soft. If it didn t melt or
get soft, what happened after 10
minutes?
• Put a piece of chocolate in a paper
plate in the SUN. Record how long
does it take for chocolate to melt or
get soft.
QUESTIONS
1. Where did chocolate melt
faster? How long did it take
for it to melt?
2. Why does chocolate melt?
3. What happens with
chocolate molecules when it
melts?
4. What happens if you put the
melted chocolate in the
fridge? Why?
5. Where do chocolate
molecules move faster? In
the shade, in the sun or in the
fridge?
8. MATTER STATES: EXPERIMENTS
WATER STATES
You need:
• 1 ice cube
• 1 bowl
• Paper and pen to record your
results.
Process:
• Put the ice in the bowl.
• Leave the ice in the kitchen and
write how long does it take for the
ice to melt completely.
• Leave the melted ice(water) in the
bowl in the kitchen for several days.
• Record how long does it take for the
water to evaporate (there is no
water in the bowl)
QUESTIONS
1. How long did it take for the
ice to melt?
2. What happens to ice
molecules when it is melting?
3. How long did it take for water
to evaporate(disappear from
the bowl)?
4. What happens to water
molecules when it
evaporates?
5. Where did the evaporated
water go? What is it now?
9. 3. ACTIVITIES AND RESOURCES
MATERIALS
1. Take 5 objects and write the materials they are made out of.
1. Classify into:
• Natural materials
• Artificial materials
2. Classify according to properties:
• Strong
• Flexible
• Elastic
• Weak
3. Do the experiment that you can find in the next slide.
10. EXPERIMENT: BUILDING PAPER BRIDGES
Take a piece of paper and hold it
between 2 boxes as a bridge.
Put something on it. What
happens?
Now fold the paper as a paper fan
and hold it between 2 boxes again.
What happens now?
Why do you think that happened?
Try to explain what you have seen.
11. 3. ACTIVITIES AND RESOURCES
RECYCLING
1. Do you recycle at home? What do you do to recycle?
2. Explain the three R s:
• Reduce
• Reuse
• Recycle
3. Play these games:
• http://www.sciencekids.co.nz/gamesactivities/recycling.html
• http://kids.nationalgeographic.com/kids/games/actiongames/recycle-roundup/
4. Have a look at this website to get some ideas on recycling:
• http://www.epa.gov/recyclecity/mainmap.htm
12. 4. EVALUATION
The last day to give in the work is:
Friday 31st May 2013
The teacher will evaluate:
• Giving in the work in the set day.
• Doing all the activities proposed.
• Presentation and organization.
Remember: you can send it to me by e-mail or give it to
me in class.
Ask me every doubt you have.
