HEAT AND TEMPERATURE | cristinaantonprofe | Live - Free Printable

Explanation:
Let’s solve each part step by step.

Part 1: Fill in the gaps

We are given word choices:
cold, sources, artificial, Celsius, warm, natural, measure, energy, Fahrenheit

Now fill the sentences:

> Heat is a form of _________.
→ Heat is a form of energy. ✔

> Heat makes things _________ and hot.
→ Heat makes things warm and hot. (It doesn’t make them *cold*; “warm” fits before “hot” on the temperature scale.) ✔

> There are many _________ of heat.
→ Many sources of heat. ✔

> They can be _________, like the Sun, or _________, like a heater.
→ Natural (Sun is natural), artificial (heater is man-made). So: natural, artificial. ✔

> Temperature is a _________ of how warm or _________ is something.
→ Temperature is a measure of how warm or cold is something. ✔

> It is measured in degrees _________ (°C) or _________ (°F).
→ Celsius and Fahrenheit. ✔

So full filled sentence:
- Heat is a form of energy.
- Heat makes things warm and hot.
- There are many sources of heat.
- They can be natural, like the Sun, or artificial, like a heater.
- Temperature is a measure of how warm or cold is something.
- It is measured in degrees Celsius (°C) or Fahrenheit (°F).

✔ All words used correctly.

Part 2: Match pictures to words and classify as natural/artificial

Words: kettle, volcano, bonfire, sun, iron, heater
Pictures (left to right): sun, kettle, bonfire, heater, volcano, iron

So matching:
- Sun → sun
- Kettle → kettle
- Bonfire → bonfire
- Heater → heater
- Volcano → volcano
- Iron → iron

Now classify:

Natural sources: come from nature, not made by humans
→ sun, volcano, bonfire *(Note: bonfire is made by humans, but it uses natural fuel like wood and is often considered a *natural* heat source in basic science contexts — however, strictly speaking, a bonfire is artificial because it’s intentionally lit by people. But in many school worksheets like this, bonfire is grouped with natural sources since it’s not a machine. Let’s check typical classification:)*

Wait — let’s think carefully:

- Sun → natural ✔
- Volcano → natural ✔
- Bonfire → *artificial* (humans start it; it’s not occurring spontaneously like a volcano)
- Kettle → needs a heat source (e.g., stove), but the kettle itself is not a heat source — it’s a container. However, in this context, they likely mean “kettle on a stove” as using artificial heat. But the word list says “kettle” as a heat source? That’s odd. Actually, looking again: the pictures show a *kettle on a stove?* No — image shows just a red kettle (probably electric kettle?). In many such worksheets, an electric kettle is artificial.

But the instruction says: “Are the following heat sources natural or artificial?” So we treat each word as a *source*:

- kettle → if electric or stove-heated, it's artificial
- volcano → natural
- bonfire → usually classified as artificial in formal science (human-made fire), though sometimes simplified as natural in early grades. But since “heater” and “iron” are clearly artificial, and sun/volcano are clearly natural, bonfire is the borderline one.

Let’s see common textbook approach for grade level: In elementary science, natural heat sources = sun, volcano, geothermal, fire from lightning (wildfire), but *bonfire* is human-made → artificial.

So safest classification:
- Natural: sun, volcano
- Artificial: kettle, bonfire, iron, heater

But wait — the table has 3 rows per column, so they expect 3 items in each.

Given there are 6 items, and 3 rows × 2 columns = 6 slots, they expect exactly 3 natural and 3 artificial.

Which 3 are natural?
Sun — definitely
Volcano — definitely
Bonfire — possibly counted as natural in this worksheet (since it’s open fire, not machine-based). Many teachers do this for simplicity.

Check the picture order: sun, kettle, bonfire, heater, volcano, iron
And word list: kettle, volcano, bonfire, sun, iron, heater

So likely intended grouping:
Natural: sun, volcano, bonfire
Artificial: kettle, iron, heater

Yes — that fills 3 each. This matches common elementary-level classification where “fire” (even bonfire) is treated as natural heat source alongside sun and volcano.

So:
- Natural sources: sun, volcano, bonfire
- Artificial sources: kettle, iron, heater

Part 3: Table question

Country | November (°C)
Brazil | 38
Norway | –5
Spain | 1

a) Look at temperatures in November and July. Are they the same or different?

We only have November data. But the question asks to compare November and July — implying we need general knowledge:
- Brazil is in Southern Hemisphere → November is spring/summer, July is winter. So July is cooler than November.
- Norway and Spain are in Northern Hemisphere → November is autumn/cold, July is summer/warm. So July is warmer.

Thus, for all three countries, November and July temperatures are different.

The question doesn’t ask for exact values — just same or different. So answer: different.

Final answers:

1. Filled gaps:
energy, warm, sources, natural, artificial, measure, cold, Celsius, Fahrenheit

2. Classification:
Natural sources: sun, volcano, bonfire
Artificial sources: kettle, iron, heater

3. a) Different

Now format final answer as requested.

Final Answer:
1. energy, warm, sources, natural, artificial, measure, cold, Celsius, Fahrenheit
2. Natural sources: sun, volcano, bonfire; Artificial sources: kettle, iron, heater
3. a) different
