The shape of the Earth and its space
1. Ask learners to choose the correct shape of the Earth from the items inthe box. They must explain why they chose that shape.
2. Hand out sheets of newspaper and strips of white paper.3. Make water and flour glue.4. Give learners a copy of the map of the world (see pages 36–37) to cut
and paste onto the dry Earth models.5. Also supply the learners with a piece of pantihose to put around their
models to represent the thin air.
Make a paper model of the Earth1. Crumple 10 sheets of newspaper to make a tight ball shape.2. Tear two or three sheets of white A4 paper into thin strips.3. Make a glue paste out of flour and water.4. Spread the glue paste onto the strips of white paper with your fingers.5. Bandage the strips around the ball of newspaper until the ball is
completely covered.
6. Put your model in the sun to dry.Next day:1. Draw an equator line on your globe (model of the Earth).
Draw a spot for the North Pole and the South Pole.2. Cut out the continents from the map of the world.3. Paste the continents onto the model in the correct position (use a
map and the equator line to help you).4. Colour the land in orange. Colour the water in blue.5. Put on the air – remember it is a very thin layer. (Stretch a piece of
pantihose around your model to represent the thin layer of air.)6. Complete the task card “Our Earth is like a ball moving in space”.
• The Earth is round like a ball. It is spherical in shape.• The Earth’s surface consists of land and water.• There is more water than land on the surface of the Earth.• The atmosphere is a thin layer of air surrounding the Earth.• Outer space is beyond the atmosphere.

Day and night
Introduction1. Introduce the words rotate and rotation, revolve and revolution. Refer
to the reading below in order to explain these words.
The Earth moves in two different waysThe sun is a star. The sun is at the centre of our solar system. It spins
but it always stays in its same position at the centre.
There are nine planets that move around the sun. Each planet
travels in its own, almost circular, pathway around the sun. This
pathway is called the planet’s orbit. The Earth takes one year to travel
around the sun. When it travels in its orbit we say it is
revolving. It revolves once around the sun each year.
But at the same time each planet spins on its own
axis like a top. We call this spinning motion rotation.
So each planet spins on its own axis at the same time as it is
moving around the sun. A planet rotates on its axis and revolves
around the sun at the same time.2. Demonstrate rotating:
Ask one learner to turn round and round on thesame spot.
• The Earth’s light comes from the sun• When light from the sun falls on the Earth’s surface, it is daytime• The Earth spins on its axis (the imaginary line passing through the
Earth from North Pole to South Pole)• As the Earth spins (rotates) and it is daytime on one side of the
Earth, it is night time on the opposite side of the Earth

4. Then demonstrate spinning (rotating) and revolving at the same time:one learner stands in the middle and is the sun; the other learnerstands some distance away and begins to spin. Then at the same timeshe moves around the sun keeping the same distance from the sun.
4. Explain to the learners that our Earth moves in two ways. It rotates andrevolves around the sun at the same time. The Earth rotates once aday (24 hours), but it takes a whole year (365 ¢ days) for it to revolvearound the sun.
Showing how the Earth’s movement causes day and night1. Show the pictures representing day and night (page 33)2. Discuss with learners some of the differences between day and night3. Demonstrate how the rotation of the Earth causes day and night:
A Use two learnersA One will hold a torch and the other will hold a globe (model of the
Earth).A The learner holding the torch represents the
sun. She stands still and shines light ontothe Earth held by the other learner.
A The learner holding the Earth slowly rotates(spins) the earth.
A Learners will see that as the Earth spins,part of it is in the light and part is in thedark.
A The part in the light is experiencing day time and the part in thedark is experiencing night time.

1. Use the model of the Earth that you have made.2. Draw a cross on South Africa to mark its position on the Earth.3. Now complete the following task card.
Activity 3 Task cardDay and Night
1. Shine the light brightly onto South Africa (don’t move the torch).
A Is it day or night in South Africa when the light shines on it?
It is day time in South Africa when the light from the sun shines on it.2. Keep the Earth still.
A Is it day or night in North America when the light shines on South Africa?
It is night time in North America when the sun shines on South Africa.3. When it is day time in South Africa it is night time in North America.
4. Slowly turn the globe clockwise until it is day time in North America. Is it daytime or night time in South Africa?
It is night time in South Africa.
5. In your own words, explain how we get day time and night time.
We get day time in South Africa when our side of the Earth is facing the sun. We get night time when the Earth spins around untilour side of the Earth faces away from the sun.

The seasons
Introduction1. Start by asking questions to get the learners to think about the
seasons and how they affect us. Ask questions like:A What season is it now? A How do you know what season it is?A Is it hot or cold today?A Does it stay hot/cold all day? etc.
2. Collect pictures showing different seasons. Compare and discussthese with the learners.
3. Use the following questions to help you to compare the pictures:A What is different in the different pictures?A What kind of clothes are people wearing?A Is it summer or winter in these pictures? How do you know?
4. Read the following as background information for yourself. (You candecide whether this information is necessary for your learners at thisstage.)
The SeasonsA The seasons are caused by the Earth’s revolution around the sun.A The seasons are also caused by the fact that the Earth’s northern and
southern hemispheres are tilted towards the sun at different times inthe year.
• The Northern and Southern hemispheres experience summer and winter at different times of the year.
Activity 44
Key concept
Teacher tasks
13
A During the summer in the southern hemisphere the sun’s rays shinedirectly on the southern hemisphere and this makes it warm there.
A During the summer months in the northern hemisphere the sun’s raysshine directly onto the northern hemisphere and so it is warm in thatpart of the world.
A When it is summer in the southern hemisphere it is winter in thenorthern hemisphere.
A When it is winter in the southern hemisphere it is summer in thenorthern hemisphere.
A The sun’s rays always shine directly onto the equator throughout theyear and so this region of the Earth is always warm.
Finding out about the seasons in differenthemispheres
A Is it hot or cold today?Explain to the learners that we can find out how hot or cold it is today bymeasuring the temperature of the air.1. Supply learners with a thermometer and show learners how to
measure the air temperature with it.Note: Remember to hold the thermometer so that the bulb at thebottom is surrounded by air. Don’t hold it on the bulb because yourfingers will be in contact with the bulb and so the thermometer will bemeasuring the temperature of your fingers.
2. Explain maximum and minimum temperatures to the learners. A The minimum temperature refers to the lowest temperatures
measured on that date in that city. This is usually the night timetemperature.
A The maximum temperature refers to the highest temperaturemeasured in that city on that date. This is usually the daytimetemperature.

Finding our own maximum (highest) and minimum(lowest) temperatures at school for today:1. Are you feeling warm or cold this morning?2. Use the thermometer to measure today’s temperature at school.
Write your temperature measurements here:Early morning temperature (when school starts) = _____°C.Afternoon temperature (when school ends at 2.30pm) = ______°C.
3. What was the maximum temperature for the day? ________°C.4. What was the minimum temperature for the day? ________°C.
Supply learners with a map of the world (see page 36 and 37 ) andsynoptic charts for January and June (see page 15 and 16).
Finding out about the seasons in different partsof the world1. Look at the synoptic charts. Find the national and international
maximum and minimum temperatures.2. First find the city nearest to where you live on the synoptic chart and
also find it on the world map. 3. Then find the international cities on your synoptic chart and find them
on the map of the world. In which hemisphere is each city? Look at the map.

SummarySummer and winter seasons
Today in science we learned about summer and winter seasons.
I learned the temperature measured in a place can tell us whetherit is summer or winter there
I also learned when the maximum and minimum temperatures in aplace are high then it is summer there. When the maximum andminimum temperatures in a place are low then it is winter there.
Furthermore, I learned that when it is summer here in the southern hemisphere, then it is winter in the northern hemisphere.

Keeping a weather chart
1. Explain how to fill in the weather chart.2. Use Sunday as an example to explain how learners should fill in the
chart.3. Explain how the wind chart called the Beaufort scale works for
determining the strength of the wind (see page 20).
1. Observe the weather closely every day for one week.2. Fill in the spaces every day starting with Monday.3. Place an empty coffee bottle outside to catch the rain. Measure how
deep the water is every day in mm (millimeters). Empty the bottle outagain after you have measured the amount of water for that day. Thenleave it outside again to catch any rain in the next 24 hours until youmeasure it again.
4. Measure the temperature ofthe air in the classroom everyday at the same time (e.g.big break)
5. Use the wind chart on pages20 and 21 to observe anddecide on the wind speed.
6. Compare your completedchart with other learners.(You can also compare yourchart with the weather chartin the newspaper each day)
• Weather refers to the local climatic conditions every day• During each season we get daily local weather conditions such as:
wind, rain, thunderstorms, fog, cloud, sunny weather, partly cloudy.

Effects of different kinds of weather
1. Conduct a brief class discussion about the weather. Use the following questions to guide the discussion:A People usually take notice of the weather every day. Why do you
think they do?A How do rainy weather, and windy weather, and cold or hot weather
affect our lives?A Why do we sometimes say that the weather is bad?
2. Hand out pictures showing the effects of different kinds of badweather to each group of learners (see pages 40–45).
• We experience many different kinds of weather during the different seasons
• Sometimes weather can have bad effects• People have to cope with the effects of different weather

The nine planets in our solar systemAll pictures courtesy NASA
The four Galilean moons
Jupiter has 16 known moons, but four are largerthan the rest and can be seen easily withbinoculars. They are known as the “Galileanmoons” after their discoverer Galileo.
JupiterThe largest planet
Diameter 142 800 km
Mass 318 Earth masses
Distance from the sun 800 million km
Number of moons 16
Rotation period length of day in Earth hours: 9.8
Time to go round the sun length of year in Earth years: 11.9
Jupiter is the largest of the gas giants. The whiteclouds that we see are at a temperature of –153 °Cand consist of ammonia ice crystals. Lower down,the clouds are coloured red and brown by organiccompounds and chemicals such as sulphur. Windsspeeds of over 400 km/h are common. The GreatRed Spot is thought to be a long-lived hurricaneand is larger than Earth. Jupiter probably has a rockor ice core surrounded by liquid hydrogen withhelium dissolved in it.

Venus Diameter 12 104 km
Mass 0.8 Earth masses
Distance from Sun 104 million km
Number of moons none
Rotation period length of day in Earth days 243
Time to go round the sun length of year in Earth days 225
Venus is a hot and hostile planet. An atmosphereof carbon dioxide 90 times as dense as Earth’skeeps the surface hot enough to melt lead.Clouds of sulphuric acid hide its surface.
SaturnLike Jupiter, Saturn is a gas giantconsisting mainly of hydrogen andhelium. Its famous ring in fact consistsof thousands of narrow rings made upof lumps of ice and rock as small asdust grains and as large as minibus.
Diameter 120 660 kmMass 95 Earth massesDistance from Sun 1 400 million kmNumber of moons 18Rotation period length of day in Earth hours 10.2Time to go round the sun length of year in Earth years 29.5
MercuryDiameter 4 878 km
Mass 0.06 Earth masses
Distance from Sun 60 million km
Number of moons none
Rotation period length of day in Earth days: 58.7
Time to go round the sun length of year in Earth days: 88
At the equator it is hot enough to melt lead. At thepoles there are craters with ice frozen to –150°C.Mercury has no atmosphere.
UranusDiameter 51 118 km
Mass 14.5 Earth masses
Distance from the sun 3 000 million km
Number of moons 15
Rotation period length of day in Earth hours: 17.9
Time to go round the sunlength of year in Earth years: 84
Uranus shows an almost featureless green‘surface’ of clouds floating in a cold (–197°C)atmosphere of hydrogen, helium and methane.Beneath the clouds, most of Uranus (85%) isice.
EarthOur home planet
Diameter 12 750 km
Distance from sun 150 million km

The atmosphere of Mars is 100 times less densethan Earth’s and consists mainly of carbon dioxide,with traces of water vapour. In winter temperaturesdrop to –125 °C, giving Mars its well known white‘ice caps’. In summer equatorial temperatures canreach 20 °C. The planet’s reddish colour is causedby iron in the soil. Bacterial life forms may once haveexisted on Mars.
NeptuneDiameter 49 528 km
Mass 17 Earth masses
Distance from sun 4 500 million km
Number of moons 8
Rotation period length of day in Earth hours: 19.1
Time to go round the sun length of year in Earth years: 164.8
Neptune is another ‘ice giant’ like Uranus and evencolder (–225°C). Its bluish atmosphere of hydrogenand helium shows occasional large dark spots, and isprobably the windiest place in the solar system withstorm winds reaching speeds of 1400 km/h.
PlutoDiameter 2 300 kmMass 0.0025 Earth masses Distance from sun 4 400–7 400 million kmNumber of moons 1Rotation period length of day in Earth days: 6.4Time to go round the sun
length of year in Earth years: 247.7
Pluto is smallest of the planets, and usually the remotestand coldest. At –233°C, frost of methane and nitrogencoat the pinkish surface. Pluto’s grayish moon, Charon,is only 19 400 km away, and more than half Pluto’sdiameter.
The Western Cape Primary Science Programme (PSP) has been operating since 1985.
The PSP is an in-service education organisation that aims to improve the quality of teaching
and learning in the most disadvantaged primary schools. We develop teachers’ knowledge
and skills and support them in their work with learners.
We focus on the critical learning areas of the Natural Sciences (including EnvironmentalEducation), Language, Mathematics and the Social Sciences.
The PSP offers a variety of courses, develops learning experiences together with teachersand offers support in their classes.
Based on this interaction with teachers, the PSP produces innovative materials, includingteacher resource books, learner task cards and display material. All our materials are written
in easily accessible language; include careful concept progression; many activities andinvestigations, and include good suggestions for assessment.
The PSP has a vision of an excellent primary schooling for all South Africa’s children, where all educators are highly skilled, committed and confident; and are well prepared
and resourced to teach.
