Earth and Orbit
Can you name them? Can you name the planets within the solar system
How can we remember them? This is called a ‘mnemonic’ a way to help us remember the order the planets are in Planet

Mini-lesson What is orbit and how do we get there?
Vocabulary Match or define keywords in your workbook ● Orbit ● Rocket ● Space race ● Low earth orbit ● Satellite
Checks for understanding
1. What does LEO stand for? A. Large Earth Orbit B. Long Earth Orbit C. Low Earth Orbit
In your workbooks complete the missing gaps using the keywords from the word bank.
Worked Example Step 1. Turn on and pair a DC Motor block. Step 2. Drag on the following blocks to the Workspace: ● DC Motor block ● Switch Direction block ● Key Press block Step 3. Connect the blocks together in a sequence.
Worked Example
Step 4. Use the Key Press to test your system!
Step 5. Open the DC Motor block settings to change the speed.
Challenge 1 Step 1. Using card paper create a solar system. Add the orbits of each planet except the Earth. Step 2. Create the Earth separately and attach to a tennis racket-like shape. Step 3. Put a small hole in the end of the paddle and through the Sun. Put the DC Motor block through both using blu-tack or plasticine to hold in place.
Challenge 1 Step 4. Add the Slider block and the DC Motor block to the Workspace.
Step 5. Pair up the physical blocks and watch the Earth spin when the slider is moved.
Checks for understanding 1. What is the purpose of the slider? A. To just turn the motor on and o B. To adjust the speed C. To change the direction of the motor
2. How long is one orbit of the sun? A. 365 days B. 1 year C. Both A and B are the same
Challenge 1- Debug it! â—? The speed of the motor is too fast Step 1. Drag a Filter block to the Workspace.
Step 2. Edit the range of the block to 0-25.
Step 3. Connect the Filter block to the rest of the system and test it!
Challenge 2 Step 1. Look at the days it takes each planet to orbit the Sun.
Step 2. Calculate the relative time it takes for each planet to orbit the Sun, comparing them to Earth. Step 3. Set the speed of the Slider block to ‘20’ to represent Earth’s speed around the Sun. Now calculate what setting you would have to pick to represent Mercury’s Speed around the Sun.
Checks for understanding 1. Which planet is the quickest to orbit the sun? A. Mercury B. Earth C. Mars
1. Which planet takes the longest to orbit the sun? A. Earth B. Saturn C. Neptune
