My family thinks I’m really annoying. I ask questions about lots of different things. Sometimes they don’t answer me – I really hate it! It’s not my fault that everything is interesting. My cat, my parents, cooking... even the plants on the balcony!

I’ve got so many questions...

What do you think?

Do you ever feel the same as Elisa?

Can you answer your own questions?

Does learning about the world help us to look after it?

1 How does science work?

Our world is full of mysteries. Scientists use a special method to help us understand them. You can learn this method too.

The scientific method: steps

1

Looking for answers

Ask a question

Our world is full of things that we don’t understand.

That’s why we ask questions, like why does it get dark? Which is bigger: the Moon or the Sun? Does my dog see like I do? Why do I get thirsty?

2 Look for information

Scientists use the scientific method to look for answers to our questions.

3 Suggest answers

A way to look for answers In the scientific method, we follow steps to find answers to our questions.

4 Observe or experiment

Study the picture on the right. It shows the steps that scientists follow.

5 Analyse data and make conclusions

1 Guess what: scientists use it to help us understand the world around us. What is it?

2 Say the name of a scientist you know. Tell the class about them and about their scientific work.

3

10

Draw a picture of a scientist (don’t let anyone see it). Then show your drawing to the class. Which parts of your classmates’ drawings are similar? Which parts are different?

6 Share your conclusions

Take note!

Following the scientific method. Is it cientists make many discoveries that help you every day!

Asking scientific questions

Language Bank

Elisa asks lots of questions. She’s curious about everything. Are you like Elisa? Curiosity lets us discover new things.

Writing. Think of a problem and use the steps of the scientific method to show how you can solve it.

Speaking.

Explain the steps of the scientific method to your classmates and share your conclusions.

What questions can you ask?

You can use the scientific method to answer some questions about the world around you.

But you can’t use this method to answer every question. Science can’t answer questions about what people like. For example, why do you like chocolate more than soup? And science can’t explain why we think something is good or bad, beautiful or ugly, interesting or boring...

Questions, questions and more questions Read these two situations. Then answer the questions in your notebook.

Take note!

You can’t use the scientific method to answer every question. Use it in the right situations.

It’s the final of the ‘Be st Singer’ contest! Th e public votes for the winner.

There’s a huge dead animal on a beach. It’s soft and long. It has two really long tentacles and giant eyes. Lots of people want to see it.

What is it?

Where is it from?

Who is the best singer?

It is an alien?

1 Which questions can you answer with the scientific method? Which questions can’t you answer with this method?

Who is the public’s favourite?

2 Which questions are about people’s preferences?

3

Suggest another two questions for the beach situation that you can answer with the scientific method.

Question

3 Looking for scientific information Science sounds so exciting! Before you start your research, check if other people already know something about your topic.

Why do we look for information?

One of the first steps in the scientific method is looking for information.

Looking for scientific information means finding out what people already know about our topic.

For example, imagine you want to know why fish don’t drown in water. First, you need to look for existing information about this topic. Then you can make your own observations.

Where to find information

1 Where can you find printed information?

Where can you find digital information?

2 Find a printed scientific book.

Write its title, the author and the topic.

3 Find a science documentary. Say the title and what it is about.

Always use scientific sources. Look at the picture. It shows the main sources of scientific information.

Sources can be printed, such as books, or digital, such as websites.

Sources of scientific information

3 Find out when World Whale Day is. Why do we celebrate this day? Say which sources you use to find the answers.

Take note!

You can find scientific information in lots of different sources.

Are you familiar with all of them?

4 Suggesting answers and checking them Language Bank

When we research something that we don’t understand, we usually have some ideas to explain what is happening. Let’s start there!

Speaking. Follow the steps at home and share what happened in groups.

1. Fill a plate with water.

After we look for information, we suggest answers to our scientific question, or explanations for what is happening. These explanations are called hypotheses.

What is a hypothesis?

A hypothesis is a possible answer to a scientific question.

When we make a hypothesis, we don’t know if it is correct. We have to do experiments or make observations to check our hypothesis.

The results of our experiments and observations tell us if our hypothesis is correct. If the results don’t match our hypothesis, we need to make another one!

2. Sprinkle pepper across the surface of the water.

3. Make a hypothesis about what you think is going to happen.

4. Put your finger in detergent and dip it into the water.

5. What happens? What can you see?

Writing. Answer the question in your notebook: What can you do to check a hypothesis?

Hypotheses are really important!

Paula’s dad put a bottle of water in the freezer and forgot about it. Now it’s broken!

It’s Manuel’s birthday today, and it’s really hot. Manuel is decorating the garden with balloons. At midday, almost all the balloons are burst!

Scientific question: Why are the balloons burst?

Scientific question: Why is the bottle broken?

1

14

Suggest a hypothesis for each scientific question.

Prediction

2 In your notebook, write the steps for checking each hypothesis.

U1 Hi! I’m Teo and I’m a chemist. I love to do experiments!

Checking hypotheses Sometimes we do laboratory experiments, and sometimes we make field observations.

I do experiments! I make observations! out if a hypothesis is correct.

An experiment is a test to find trol certain things, such as the When I do an experiment, I con stances I use. This means I can temperature or how many sub experiments. compare the results with other tory. It has lots of scientific I do my experiments in a labora equipment. eriments in a laboratory I write everything about my exp notebook.

Hi! I’m Ana and I’m a zoologist. I observe animals outside in their natural environment.

Sometimes it rains, sometimes it’s cold, and sometimes it’s really hot. I can ’t control the field conditions when I make my obs ervations. I write everything in my field notebo ok.

I use my binoculars to observ e things that are far away, and a magnifying gla ss to study small animals in detail.

Sometimes I take photos of the things that I see.

And I always take a compass and a map so that I know where I am.

1 Who can answer these scientific questions – Elisa or Teo? a) How many vultures live in this area? b) How much sugar does packaged juice contain? c) What do ladybirds eat? d) Which freezes first: sugar water or salt water?

Take note!

It’s easy to experiment and make observations.

You can even do it at home!

15

5 Analysing data, making conclusions and sharing them When we experiment, we collect lots of data. How can you use the data to check your hypothesis?

1 Use your own words to explain why we gather data.

Collecting data Data is the information that you get when you observe or experiment.

There are three main types of data: • Numerical data. This data is made up of numbers. For example, the number of flowers on a plant, the temperature of a liquid, the weight of a dolphin…

We use measuring devices to get this data (thermometers, scales, etc.).

• Observations. We use our sight, hearing and other senses to gather this data.

You can use special equipment like binoculars (for far away things), a magnifying glass (for small things), or a microscope (for really small things).

• Audiovisual records. This type of data includes photos, videos and audio files. For example, a recording of dolphin calls or whale songs.

3 Put the date below into the correct categories: a) Numerical or nonnumerical b) Observations or audiovisual records.

U1

Analysing and making conclusions

Analysing data and making conclusions After you write down all the data from your research, it’s time to analyse it and make conclusions.

Look at the data in these tables. Analyse the data and make your own conclusions.

Kilograms of tomatoes picked:

Analyse means to compare the data to make conclusions.

Use drawings and graphs to show your data in different ways.

A conclusion is an explanation about the data.

Conclusions let you check your hypothesis. If your hypothesis is correct, you can share your results. If it is not correct, make another one.

Do more experiments and make more observations to check your new hypothesis.

Weight Fertilised tomatoes

250 kilograms

Unfertilised tomatoes

65 kilograms

Most popular party snacks:

Sharing your research Scientists share their results with the world.

We share scientific research in different ways.

• A report is a document that tells people about your materials, steps, results and conclusions.

• A talk is a verbal presentation of your research.

• You can also use other methods, such as an article for a journal, a video or a TV report.

Language Bank Speaking. Ask your classmates about things that interest them. For example, their favourite meals or their subjects. When you get the results, talk about your conclusions with your group.

Writing. Imagine you are going on a trip with your classmates and write a report about things you need, like food, clothes, and other materials.

4 A scientist wants to share their findings about zebras. How can they share the information with these groups of people? a) Primary school children. b) Other scientists. c) The general public.

6 Solving problems

We use technology and computers every day. Learn to ‘think like a computer’!

1 What is an invention?

Give an example of an invention that you know.

2

Technology helps us to solve day-to-day problems.

All technology products start in the same way. First, we identify a problem that we want to solve. For example, how to travel quickly to faraway places. Then, we look for a solution. For example, building planes.

Some problems are easy to solve. For more difficult problems, we need to use computational thinking.

Computational thinking

Brainstorming

Say:

a) Something that you need instructions for. b) Something that you need symbols for. c) Something that you need a diagram for.

3 Which computational thinking techniques do you need for the above examples?

Computational thinking is a type of logical thinking.

It uses computing techniques to solve problems.

These are the most common computational thinking techniques: Pattern recognition Looking for repetitions.

Codification

Decomposition Dividing something complex into simpler parts.

Abstraction Focusing on the most important information.

20

Representing ideas and information with simple symbols.

Algorithms Suggesting step-by-step instructions to solve a problem or complete an activity.

Checking Checking that your solution works or if you need to improve it.

Identifying problems... ... and finding solutions Before you start to build something, you need to design it carefully and plan what to do.

Language Bank

Think First, decide what your objective is. Ask these questions: What new object do I want to make? What problem do I want to solve?

Writing. In groups, plan a healthy menu for next week. Pay attention to what food is in season and follow the project stages.

Speaking. Present your menu to your classmates. Then, they evaluate your menu.

• For an individual project, think and write down your ideas.

• For a group project, talk, share ideas and write them down.

Design Before you build something, design it. You can make a small 3D model (called a mock-up).

Decide what materials and tools you need and where to find them.

Teamwork motivates everyone to participate.

Do you need help with the materials and tools?

Plan Plan means thinking and writing down all the tasks for your project. Calculate how much time you need and decide who is going to do each task.

Your plan needs to be clear. Everyone needs to understands it. The steps need to be in order.

They created a problem-solving patrol!

Their mission: ask local people what problems they have, and create solutions. The problems and projects are on cards, but they are mixed up. They don’t know which project solves which problem!

Help the problem solvers. Match the problems to the projects.

Is there an extra project? Which one?

What problem can the extra project solve?

Finishing a project

It’s time to make your project real! Building and programming things is really fun.

Complete Completing the project means doing all the tasks from your plan.

Work with your team mates. Everyone can contribute.

Find solutions to problems together.

Evaluate Evaluating a project means analysing the results and the process.

• To analyse the result, compare your completed project with your plan. Check if they are similar or different.

• To analyse the process, compare your process with your plan. Check if you followed your plan or if you did something different. Talk with your team mates about how to improve the process and the result.

Share Sharing a project means telling others about it.

There are lots of ways to share a project: • Use posters, pictures, etc. to represent the results.

• Explain the results in a talk (with or without digital material).

• Communicate the results in articles, videos, etc.

I’m an engineer Eva is an engineer. She is visiting your school to talk about her work.

This is her presentation: out my job.

Can Eva build a bridge by herself? Explain.

If Eva doesn’t plan each project, what happens? What problems does she have?

How is Eva sharing her work?

Take note!

When you finish a project, you need to evaluate the final result. Then you can share it!

Let’s think

Doing a project step by step Try these two projects.

Your teacher will organise the class into groups. Follow the project steps from this unit to create these two projects.

Project 1: building bridges and towers with toothpicks and sweets Problem Build a bridge or a tower with materials that let you test the structure and change it.

Solution Use toothpicks and sweets to build structures that are easy to assemble and disassemble.

Material Toothpicks, jelly sweets, paper and pencil (for designing).

Steps Apply the steps from this unit. Make a task list, plan the materials and tools you need, and assign the tasks to different people.

Advice Try making different model bridges and towers.

Then choose the best ones.

Making a video game Scratch is a tool for creating stories, animations and games.

You are going to use Scratch to make a small video game.

Before you start, go to anayaeducacion.es to see how Scratch works.

Animation What do I do?

Follow these steps to create a video game: • Make an animation: a person moves across the screen.

• Create a story: two characters have a conversation.

How do I make an animation?

Choose a stage Click to choose a stage. Select one of the stages in picture A. The example shows a bedroom.

Choose the characters Click and select one of the sprites in picture B. The example shows Avery. Let’s call her Luz. You can change the size of your character.

Code for the character’s movement

Making your characters move Follow these steps: In the bedroom Tell Luz to move when you click on her.

Luz • She receives the message to move.

• Use the glide block to make her move smoothly.

• Use the next costume block to make it look like

she is walking. Use the wait block to control how fast she moves.

Creating a story Let’s make Luz and Canelo talk. Follow these steps:

Code for the story

• Canelo sends a conversation1 message.

• Luz receives the message and sends conversation2

to Canelo.

• Canelo receives conversation2 and answers Luz.
