## What are the challenges of human success?

In What are the challenges of human success? you will explore the positives and negatives of our connected world along with possible solutions to our 21st century problems. You will then propose your own vision of the future.

To get started, read carefully through the What are the challenges of human success?learning goals below. Make sure you tick each of the check boxes to show that you have read all your What are the challenges of human success? learning goals.

As you read through the learning goals you may come across some words that you haven’t heard before. Please don’t worry. By the time you finish What rea the challenges of human success? you will have become very familiar with them!

You will come back to these learning goals at the end of What are the challenges of human success? to see if you have confidently achieved them.

## Activity 4.2.1 Objectives

### Learning Goals

• Identify positives and negatives of our connected world
• Explore solutions to 21st century challenges

### Introduction

So here we are!

Today we live in a world with a population of billions of people who are able to connect with each other in an instant. And as you now know, this modern connected world would not have been possible without collective learning and the waves of technological innovation which occurred as a result.

Mission video 22: The positives & negatives of our connected world highlights some of the positives and negatives of the connected world we live in today and explores solutions to some of the challenges we face in the 21st century.

## Mission video 22: The positives & negatives of our connected world

While you watch Mission video 22: The positives & negatives of our connected world look out for the answers to the following questions:

1. 1. What are two examples of how our world is connected?
2. 2. What are some positives of our connected world?
3. 3. What are some negatives of our connected world?
4. 4. What are some possible solutions to the challenges we face in the 21st century?

Your teacher will instruct you whether you will answer the questions: as part of a class discussion; as a group/paired discussion; or independently by writing your answers in your Big History School Junior journal (if you have been provided with one).

## Activity 4.2.1 Review

### Conclusion

When we talk about ‘our connected world’ we are really talking about the world we live in today.

So where does ‘today’ appear on our History of the Universe Timeline?

Either your teacher will help you identify where it appears on the classroom display or you will refer back to the Timeline: history of the Universe worksheet you completed when you did the “3 big mission phase questions” activity. You will find a copy of Timeline: history of the Universe example in Helpful Resources.

## Activity 4.2.2 Objectives

### Learning Goals

• Identify positives and negatives of our connected world
• Explore solutions to 21st century challenges

### Introduction

As Commander Ripley stated in Mission video 22: The positives & negatives of our connected world, we know that humans are capable of amazing things when we work together! And you could be part of the next wave of technological innovation which protects the future of our planet so that humans can continue to survive and thrive.

So let’s get started. In this activity you will read the Reading: Could exciting new technologies like these help to solve our 21st century problems? which could help to spark some ideas for your own technological innovations.

## Reading: Could exciting new discoveries and technologies like these solve 21st century problems?

Your teacher will give you a copy of the Reading: Could exciting new technologies like these help to solve our 21st century problems?. Take 5 minutes to read it carefully and highlight the main points.

## Technology solution: choose a problem

Your teacher will advise you whether you will be working individually or in a group to create your own technological solution to a 21st century problem.

On the Technology solution: choose a problem worksheet you will write down which 21st century problem you would like to solve.

You will then brainstorm different possible technological solutions which could help to solve the problem you have chosen. You can either adapt existing technology or invent your own new technology.

Once you have decided on a particular technological solution, draw a labelled diagram of it in the first box. In the final box write a paragraph explaining how your technological solution works.

## Activity 4.2.2 Review

### Conclusion

If you are part of a class, your teacher will ask you and your classmates to present your technological solutions to the class. Which technological solution/s do you believe are the most likely to succeed?

Now that you have done some serious thinking about solutions to some of our most important 21st century problems, make sure you share what you have learned today with your family and friends. Because the more people who contribute their brain power to solving our 21st century problems the more chance there is we can make the world a better place - that’s the power of collective learning!

## Activity 4.2.4 Objectives

### Learning Goals

• Propose a vision of the future based on your new understanding of the past

### Introduction

You’ve finally completed your 13.8 billion year journey from the beginning of the Universe. The only thing left to do now is to use all the knowledge you have gained during that journey to look 100 years into the future and try to imagine what that future may look like. And, even more importantly, to imagine the part you may play in creating it!

## Future vision: 100 years from now

The Future vision: 100 years from now worksheet contains a giant thought cloud. Inside the thought cloud you will create your vision of the world 100 years in the future. You can use textas/pencils to draw your vision and/or cut out pictures and words to create a collage.

Take some time to brainstorm what sorts of things you could include in your future vision. Here are some ideas:

• It could be a drawing of a scene from the future
• It could be a collage of different ideas about the future
• It could be fun and very “science fiction”
• It could focus on sustainability solutions.

You then need to complete the sentence: “In the Future I will…”

Again, take the time to brainstorm some ideas:

• Is there a particular type of “expert” you would like to be in the future?
• Is there somewhere in the Universe you would like to travel?
• Is there a particular problem you would like to solve?
• What would you like to achieve?

## Activity 4.2.4 Review

### Conclusion

If you are part of a class, your teacher will ask you and your classmates to present your future visions to the class.

So you’ve made it to the end of the history of the Universe! Here are a couple of important questions for you:

• What are the most surprising things you learned about the Universe during their 13.8 billion year journey?
• How has going far back to the beginning of the Universe changed the way you see the world today and the way you see the future?

And most importantly, are you ready to embark on the your final two Mars Mission Control Reports? You will be expected to use all the critical thinking skills and Big History knowledge you have gained to successfully complete your Mars Mission.

Best of luck!

## What are the challenges of human success?

In What are the challenges of human success? you explored the positives and negatives of our connected world along with possible solutions to our 21st century problems. You then proposed your own vision of the future.

Now it’s time to revisit your What are the challenges of human success? learning goals and read through them again carefully.

As you read each learning goal, tick the check box beside it if you are confident you have achieved that learning goal.

You’ll find that some learning goals are harder to achieve than others. If you find that there are learning goals that you’re not confident you’ve achieved yet, you may like to re-watch the Mission video which relates to that learning goal and/or ask your teacher for help.
