Run, and Your Heart Speeds Up
Why does your heart pound after running up stairs? 💓 Tap through lying down to jumping rope. Bars show how many times your heart beats per minute, with matching “thump-thump” sounds. The dotted line marks your resting level, so you can see how much faster it got. 🫁 Next, breathing: when your heart works harder, your breathing speeds up too. Compare the two bars to solve questions you couldn’t answer by looking at the heart alone. ⏱️ Finally, recovery: your heart doesn’t slow down right away when you stop running. Find out how much it drops each minute and when it returns to normal. This app was made with code too · Remix it with your favorite exercise!
Keep It Clean
Teeth have more than one side! 🪥 Split the outer, inner, and chewing surfaces into upper and lower parts—six spots in all. Brush each spot for 20 seconds, and all six take exactly 2 minutes. Check what gets missed if you brush only the outside. 🍬 Next: sweets. Each time you eat candy, your teeth dissolve for 20 minutes—so the number of «times» matters more than how «much» you eat. Tap to see what happens when you spread it out. 🧼 Finally, handwashing. How much is left behind depends on how many seconds you wash. Tap to see what happens if you don’t wash. This app was made with code too · Remix it to make a toothbrushing timer for your class!
What Sleep Does
How much should we sleep in 24 hours? 🛏️ Each square is one hour. Tap the hours to split the day into sleep and awake time. When you reach the green spot, you’ve got the right amount. 🕘 Next, count backward: if you wake up at 7 a.m., what time should you go to bed? Go to bed an hour later and you lose exactly one hour of sleep—tap to check it out. 😴 Finally, watch sleep debt pile up. If you miss just 3 hours a day, how much builds up after several days? Find the day it passes half a day, then a whole day. It happens sooner than you think. This app was made with code too · Remix it and add your family’s wake-up time!.
