One question. The next step.

Let's open a music question, work on it in a Space and link what we learned to the map.

From one stuck question to a week you planned yourself.

A student walks beside Aysel the deer along a forest path where glowing waymark stones lead to a stone arch

Why does the Moon follow our car?
Drive down the road and watch what slides past the window.
Tree, 20 m away
0°
Hills, 600 m away
0°
Moon, 384,400 km away
less than 0.001°
Distance driven0 m
Why?
The closer something is, the faster it slides past. The Moon is so far away that driving a whole kilometre hardly changes where you see it, so it seems to come along with you.
How Aysel teaches it
1. Step 1 of 3: Notice: Aysel asks what you see from the car window. The trees rush, the hills creep, the Moon stays.

Up 20%, then down 20%: why isn't it back to 100?
Move the percentage and watch where it lands.
4 short of 100 · The fall takes 20% of 120, not of 100: that's 24.
Percent20
+20% takes 100 to 120; −20% takes 120 to 96, 4 short of 100.
Why?
The rise is a percent of 100; the fall is the same percent of a bigger number, so it takes more. You always land p²/100 below: 20% leaves you 4 short, 40% leaves you 16 short.
How Aysel teaches it
1. Step 1 of 3: Guess first: 100, 96 or 104?

Why “kitaplar” but “evler”?
Tap a Turkish word and watch which vowel decides its plural.
kitaplar
The last vowel “a” is a back vowel → -lar
Try your own Turkish word
Most words follow the rule; some loanwords don't, and Aysel can tell you which.
kitap: kitaplar
Why?
Turkish suffixes follow the word's last vowel. Back vowels (a, ı, o, u) take -lar and front vowels (e, i, ö, ü) take -ler, so your tongue stays where it already is. A few loanwords, like saat, break the rule.
How Aysel teaches it
1. Step 1 of 3: Notice: Aysel puts kitap → kitaplar and ev → evler side by side and asks what's different.

Why does paper give up after about 7 folds?
Fold it in half. Then again. Watch the stack grow.
0 folds
1 layer
0.1 mm thick
Face of the A4 sheet: 297 × 210 mm
Folds
Why?
Each fold doubles the thickness and halves the face. After 7 folds an A4 sheet is 128 layers thick and about the size of a stamp, so your hands can't bend it any more. On paper, 42 folds would reach past the Moon.
How Aysel teaches it
1. Step 1 of 3: Guess first: how thick would the paper be after 10 folds?

Seven words, seven meanings: which one do you stress?
Tap a word to say it louder, and watch the meaning move.
Tap any word above.
A hummed pitch line, not a voice.
Why?
In English the stressed word carries the news. Same words, different meanings: that's why stress and intonation count in IELTS Speaking, where pronunciation is one of the four criteria.
How Aysel teaches it
1. Step 1 of 3: Listen: Aysel gives you the sentence and one situation: “You think I accused her?”
