+# Structured House
+
+Your task is to use variables to build the house.
+
+Change all the inputs in the functions to use variables.
+
+Set all the variables at the top before the first functions are used. We've set the first few to get you started.
+
+Every variable should either be:
+
+- A number that is specified in the instructions (e.g. the height of the frame); or
+- A formula between two variables (e.g. `set roof_left to house_left - roof_overhang`) or a variable and a number specified in the instructions (e.g. `set door_knob_right to door_right - 1`).
+
+Do **not** manually set variables to numbers you've calculated yourself (e.g. DO NOT set `roof_left = 16`)
+
+The purpose of this exercise is get keep pushing you towards structured, ordered thinking. Take your time.
+
+As a reminder, the house should continue to look like this:
+
+<img src="https://assets.exercism.org/bootcamp/graphics/jumbled-house-finished.png" style="width: 100%; max-width:400px;margin-top:10px;margin-bottom:20px;border:1px solid #ddd;border-radius:5px"/>
+
+### House Instructions
+
+- The frame of the house (the big square) should be 60 wide and 40 height. It should have it's top-left corner at 20x50.
+- The roof sits snuggly on top of the house's frame. It should overhang the left and right of the house by 4 on each side. It should have a height of 20, and it's point should be centered horizontally (50).
+- The windows are both the same size, with have a width of 12 and a height of 13. They both sit 5 from the top of the house frame, and 10 inset from the sides.
+- The door is 14 wide and 18 tall, and sits at the bottom of the house in the center.

+# Sunset
+
+Your task is to animate the following scene to make the sun set.
+
+The animation should last `100` iterations and look something like this.
+
+<img src="https://assets.exercism.org/bootcamp/graphics/sunset-frames.png" style="width: 100%; margin-top:10px;margin-bottom:20px;border:1px solid #ddd;border-radius:5px"/>
+
+We've drawn the initial scene for you. You need to animate a few things:
+
+- The size of the sun. It should start with a radius of `5` and grow by `0.2` each iteration.
+- The position of the sun. It has an initial center of `50, 10`, and should lower in the sky by `1` each iteration.
+- The color of the sun from yellow to orange. You can use RGB or HSL. Use a color picker such as [this](https://htmlcolorcodes.com/color-picker/) to find a starting point and ending point you want to animate between.
+- The color of the sky. Again, you can use RGB or HSL. It's not possible to animate a true set of sunset colors this way, but be creative and choose something you like.
+
+Remember to `set` the initial values **outside** of the `repeat` block, and then `change` them **inside** the block.
+If you need a recap on how to animate things, make sure to watch the Level 2 live session back.
+
+The animation will flash a bit. That's expected. We'll learn how to fix that in a future lesson.
+
+The functions used in this exercise are:
+
+- `circle(center_x, center_y, radius)`
+- `rectangle(x, y, width, height)`
+- `fill_color_rgb(red, green, blue)`
+- `fill_color_hsl(hue, saturation, luminosity)`
+
+If you need help remembering how to use any of these functions, you can watch back the video from week 1.
+
+None of the individual things you need to do are hard. But putting them together may feel daunting and unfamiliar. Plan first. Then take each step at a time, and you'll get there. If you need help, please ask on the forum, and remember to give us lots of information about what's not working and why you think that's the case!

+# Rolling ball
+
+Your task to animate the ball to move ("roll") from the tee on the left to the hole on the right.
+
+Some details:
+
+- The ball has a radius of `3`.
+- It sits on the grass at a `y` of `75`.
+- It starts on the tee at `28` from the left.
+- It should roll until it is `88` from the left
+
+You'll need to use the following functions to draw things:
+
+- `clear()` (Remember you need to use this at the start of each iteration)
+- `circle(center_x, center_y, radius)`
+- `fill_color_hex(hex)`
+
+You'll also need to use the `set`, `change`, and `repeat` keywords.
+
+You can use whatever color your like for the ball, but a bright blue might be helpful as it's a little small to see!
+
+- `fill_color_rgb(red, green, blue)`
+
+If you feel stuck or overwhelmed, watch the Level 2 video back.

+# The Penguin
+
+Your task is to make the penguin symmetrical.
+
+It should look like this:
+
+<img src="https://assets.exercism.org/bootcamp/graphics/penguin-finished.png" style="width: 100%; max-width:400px;margin-top:10px;margin-bottom:20px;border:1px solid #ddd;border-radius:5px"/>
+
+We've drawn the left hand side for you, and added `TODO` comments for each of the things you need to do.
+
+You'll need to think about setting the right colors before drawing things.
+
+For the nose, you should **change** the middle coordinates of the triangle. Don't add a new triangle.
+
+The functions used in this exercise are:
+
+- `circle(center_x, center_y, radius)`
+- `rectangle(x, y, width, height)`
+- `ellipse(center_x, center_y, radius_x, radius_y)`
+- `triangle(x1,y1, x2,y2, x3,y3)`
+- `fill_color_hex(hex)`
+
+If you need help remembering how to use any of these functions, you can watch back the video from week 1.

+As you get each bit right, tidy up the comments by removing the `TODO` and replacing it with a nicer comment.

-# The Penguin
+# Rainbow
 
-Your task is to make the penguin symmetrical.
+Your task is to make a beautiful rainbow like this:
 
-It should look like this:
+<img src="https://assets.exercism.org/bootcamp/graphics/rainbow-finished.png" style="width: 100%; max-width:400px;margin-top:10px;margin-bottom:20px;border:1px solid #ddd;border-radius:5px"/>

+The rainbow is made up of lots of bars.
 
-We've drawn the left hand side for you, and added `TODO` comments for each of the things you need to do.
+**Before reading any more of the instructions**, take a few minutes to work out conceptually how to achieve this. Write down the steps you think you need to follow on a piece of paper.
 
-You'll need to think about setting the right colors before drawing things.
+**Once you've got a solution** you're happy with (or given up), **scroll down** to see the instructions...
 
-For the nose, you should **change** the middle coordinates of the triangle. Don't add a new triangle.
+<hr class="border-borderColor5" style="margin:80px 0"/>
+
+## How to solve it...
+
+- The rainbow is made up of `100` bars, each with a width of `1`, starting at the top and being `100` high.
+- You need to set variables for `x` and for the `hue` of the color (both starting at `0`)
+- You need to write a repeat loop that repeats 100 times.
+- In each iteration of the repeat loop you need to increase `x` by 1 and increase the hue by `3`.
+- You then need to use the `fill_color_hsl` (with saturation and luminance set around 50), and `rectangle` functions to draw.
 
 The functions used in this exercise are:
 
-- `circle(center_x, center_y, radius)`
 - `rectangle(x, y, width, height)`
-- `ellipse(center_x, center_y, radius_x, radius_y)`
-- `triangle(x1,y1, x2,y2, x3,y3)`
-- `fill_color_hex(hex)`
+- `fill_color_hsl(hue, saturation, luminance)`
 
-If you need help remembering how to use any of these functions, you can watch back the video from week 1.
+If you need help remembering how to use any of these functions, you can watch back the video from week 1. If you need help with variables or animation, watch back the video from week 2!

+# Sprouting Flower
 
-This is definitely a tricky exercise and will take time to get right!
+Your task is to make a flower that grows.
 
-If you need help, please ask on the forum, and remember to give us lots of information about what's not working and why you think that's the case!

+
+The key to this exercise is to build relationships between the different elements. This is a key skill in programming.
+
+**Before reading any more of the instructions**, take a few minutes to work out conceptually how to achieve this. Write down the steps you think you need to follow on a piece of paper.
+
+**Once you've got a solution** you're happy with (or given up), **scroll down** to see the instructions...
+
+<hr class="border-borderColor5" style="margin:80px 0"/>
+
+## How to solve it...
+
+The key component of this is the center of the flower. Everything else can be calculated off that center point. On each iteration of the loop, the center point should move up by `1` (before drawing).
+
+Here are some other things you need to know:
+
+- The `flower_radius` starts at `0` and should increase by `0.4` on each iteration (before drawing)
+- The `pistil_radius` starts at `0` and should increase by `0.1` on each iteration (before drawing).
+- The `stem_width` is 10% of the `stem_height` (so `stem_height / 10`).
+- Everything is centered on the horizontal axis.
+- The `x_radius` of the leaves is 50% the radius of the flower.
+- The `y_radius` of the leaves is 20% of the radius of the flower.
+
+The functions you'll use are:
+
+- `circle(center_x, center_y, radius)`
+- `ellipse(center_x, center_y, radius_x, radius_y)`
+- `rectangle(x, y, width, height)`
+- `fill_color_hex(hex)`
+
+It is **essential** to work on one thing at a time:
+
+- Start by drawing the pink flower and getting it to move up.
+- Then get it to grow.
+- Add the smaller yellow center..
+- Add the stem.
+- Add the left leaf.
+- Add the right leaf.
+
+Use the scrubber bar to scroll through the code and work out where things are going wrong.
+
+### The final flower
+
+If something's not working, here are some values you can check against (toggle the switch on the scrubber bar to get information):
+
+First drawn flower:
+
+- Flower: `circle(50, 89, 0.4)`
+- Pistil: `circle(50, 89, 0.1)`
+- Stem: `rectangle(49.95, 89, 0.1, 1)`
+- Left leaf: `ellipse(49.75, 89.5, 0.2, 0.08)`
+- Right leaf: `ellipse(50.25, 89.5, 0.2, 0.08)`
+
+Final drawn flower:
+
+- Flower: `circle(50, 30, 24)`
+- Pistil: `circle(50, 30, 6)`
+- Stem: `rectangle(47, 30, 6, 60)`
+- Left leaf: `ellipse(35, 60, 12, 4.8)`
+- Right leaf: `ellipse(65, 60, 12, 4.8)`
+
+### This is a tough exercise!
+
+This is a challenging exercise. Take your time, and if you get really stuck, ask for help on the forum, and remember to give us lots of information about what's not working and why you think that's the case!
+
+Remember, the learning is in the struggle! Every time you get something wrong and solve it, you're becoming a coder, and eventually it will feel easy. Just keep going!

+Last week we touched on the absolute basics of coding - using functions. Hopefully you had lots of fun testing your drawing abilities, and getting creative with colors.

-In Level 2, we're going to build on what we learned last week, and look at when code moves beyond a linear list of commands, exploring loops, conditionals, variables, and writing our own functions. This is the most full content-rich week of the whole Bootcamp, and we'll cover quite a lot of ground, so take it slowly and make sure you understand each part thoroughly.
+I think this is one of the most challenge weeks of the whole bootcamp. Stick with it - you'll get through it. Just keep watching back the video if you need a reminder, keep asking yourself what each line of code does and visualise Jiki as you do so.
+
+Good luck, and use our support on Discord and the forum if you get stuck!

 ## Overview
 
-With a little bit of code, you can draw almost anything!
+In this project, we're going to learn use animation, functions and conditonals to build some basic game mechanics.
 
-In this project, we'll explore drawing and animation, teaching you some of the key programming concepts, and getting you familiar with how to make your own graphics that you can use in your games, applications and websites.
+We'll start by animating a simple ball, then work out when it drops into the hole, and add scoring.
