CHALLENGE TITLE

SOLAR SYSTEM SAFARI

This is a group challenge.

ABOUT THIS CHALLENGE

In this challenge, you will become space explorers as you journey through the Solar System! First, you’ll test your knowledge with a fun online quiz, before using digital research skills to investigate the planets and create your own colourful planet posters filled with facts and surprising discoveries. Finally, you will build an amazing scale model of the Solar System, measuring out the distances between planets and placing your posters in their correct positions, to show our place in space!

To complete this challenge, you will

MATERIALS REQUIRED

BACKGROUND INFORMATION

Our Solar System consists of the Sun (a star) and many other objects which travel around it, on a path called an orbit. These objects include 8 planets, 5 dwarf planets, over 200 moons (smaller objects which orbit the planets), and thousands of asteroids and comets. Most asteroids (small rocky bodies) are found in the main Asteroid Belt between Mars and Jupiter. Beyond Neptune is an area called the Kuiper Belt where thousands of small icy bodies, as well as the dwarf planet Pluto, are found. All these objects are kept in orbit around the Sun by the Sun’s gravitational pull. The Sun is by far the biggest object in the Solar System, making up over 99% of the mass of the entire Solar System! Our planet, Earth, is the only planet that we know of that supports life.

SOLAR SYSTEM SAFARI

PRELIMINARY ACTIVITY

Part 1 - KNOWLEDGE CHECK

First, you are going to do an online quiz to check your solar system knowledge!

Procedure

1. Using the EduSpots tablet or any other device, copy this link to run the quiz: https://wordwall.net/resource/49447/solar-system-quiz

2. Follow the instructions to answer the multiple choice quiz questions

3. As soon as you answer, you will be told if the answer is correct or incorrect

4. If incorrect, the correct answer is automatically revealed

Did any of the answers surprise you?

If so, you can research online to learn more or find explanations. The following websites have lots of great information on the solar system:

General information on the solar system: https://www.schoolsobservatory.org/learn/space/solar-system

Solar system information from NASA: https://science.nasa.gov/solar-system/ 10 facts you didn’t know about our solar system: https://www.bbc.co.uk/bitesize/articles/zkdbqp3#zwtxwsg

Part 2 - PLANET POSTERS

In groups, you will research a planet using an online solar system model, then create a poster about each planet.

1. Get into groups. (Ideally you will need 11 groups or pairs –one for each planet, plus the Sun, asteroid belt and Pluto. If you don’t have enough club members, each group can research 2 planets instead, or you can stick to just the 8 planets only)

2. Use the SolarSystemScope online model, plus other resources if you wish, to research your chosen object. Find out the basic facts plus at least one exciting “fun fact”! (Details of how to use SolarSystemScope are in the Appendix at the end of this document)

3. Create a colourful and eye-catching poster about your object. Include a drawing of the object, at least 3 basic facts, and 1 fun fact! These posters will be displayed in your classroom or Spot, so use your creativity to make them attractive and informative (see examples below).

4. Each group should present their poster and what they have learned to the other club members

5. Create a video where one Spark from each group presents their planet poster and shares ONE fun fact they discovered about the planet – try to find something that will wow everyone!

Examples of Planet Posters

These examples are just to inspire you - use your imagination to create something original and exciting

SOLAR SYSTEM SAFARI

MAIN CHALLENGE

You are going to create a scale model of distances in the solar system that will be displayed in your Spot/classroom/school for all to see!

Can you say what is wrong with this image:

This image shows us the regions of the solar system and the various objects within it, but it doesn’t give any idea of the actual size of the solar system, and how far away the planets are from the Sun. It looks as though the planets are equally spaced from the Sun. But is that correct? You are going to create a scale model to show you the true picture of distances of planets from the Sun!

The table below shows the actual distances of the planets from the Sun:

Now we can use this scale factor to work out where all the other planets will be along the distance scale

If the Sun is at one end of the room, where will Mercury be?

Mercury is 57 million km from the Sun, so using our scale factor that would be 57/12 cm away from the Sun = 4.75 cm

Venus is 108 million km from the Sun, so using our scale factor that would be 108/12 cm away from the Sun = 9 cm etc

4. Calculate your scale factor (as shown in the example above) using the length of your chosen space

5. Using the scale factor, calculate the positions of the planets on your model, and fill out the table below. You will be using the formula below:

Note: that the 2nd and 3rd columns are showing the SAME NUMBER , but in DIFFERENT UNITS.

1. Your solar system distance scale is going to be put on display somewhere in your school/Spot, so first, find a suitable space. This could be along one wall of a classroom or library, or along a corridor outside several classrooms. Ideally you want a space at least a few metres long.

2. Measure the length of your space - that length (L) will represent the distance from the Sun to Pluto/Kuiper Belt on your scale model

3. To decide where each of the planets will be placed between the Sun and Pluto on your model, you need to work out your scale factor. In other words, if the length of the space represents the distance from the Sun to Pluto, what distance does 1cm represent?

Example

Suppose your room length is

The

from the

is 5,900,000,000km or 5900 million km

So in this case the scale is 500cm to 5900 million km

Which means that 1cm represents 5900 / 500 million km = 11.8 million km

So 1cm represents 11.8 million km, this is your scale factor. For simplicity, let’s round it up to 12 million km

MAIN CHALLENGE (continued)

6. You will need either a long piece of paper that will reach the full length of your space, or you could use a long piece of string, drying line etc.

7. Mark the Sun at one end of your model, and Pluto/Kuiper Belt at the other

8. Using the calculations from the table above, mark the positions of the planets along your distance scale (if you are using paper you can mark the positions with a pen, if you are using string you can mark the positions by tying knots in the string) 9. Now that your scale model is complete you can fix it to the wall 10 Place the posters you created earlier in the correct positions below your scale model (you might find you have to use paper/cardboard arrows or string to connect the poster to the position of the planet on the scale model)

11 Now everyone can see the amazing work you have done and can also learn about our place in space!

Discussion points for your video

Create a short video showing your solar system distance model in place, with different Sparks talking about the following discussion points:

Does anything surprise you about your solar system distance model? What have you learned about the distances of the planets from the Sun?

planet in the Solar System would YOU like to visit, and why? What does the model tell you about what the temperature might be like on each planet?

All life on Earth needs water, so when scientists are thinking about whether life could exist on other planets, the first thing they look for is water. Do you think liquid water could exist on other planets apart from the Earth? Why or why not? Show your scale model on the wall, with different Sparks sharing each discussion point. Make sure all group members get a chance to speak!
