Get ready to make a splash! In this Quack’s Apples app, which features, the hilariously quirky duck, Quack, kids roll apples into the pond for his fish museum. Watch out for the rabbit holes! (Bunnies don't seem to share.)

In the Quack’s Apples app, kids can have as many tries as they need to perfect their route for the getting Quack’s apples to roll into the pond. Quack has an unlimited supply of apples, though there seem to be an unlimited supply of sticks too! By encouraging kids to keep testing and tweaking their designs until they get that apple in the pond, they are practicing the engineering design process integral to scientific thinking.

Players can't get rid of the sticks that block the apples from rolling into the pond, but can tap on them to turn them in different directions to create a path for the apples to roll into the water. Once they get it, the next setup will be a little harder.

The PEEP and the Big Wide World Trash Stash app from WGBH was produced by WGBH, the producers of PEEP and the Big Wide World, with additional development work by CloudKid. The animated series PEEP and the Big Wide World gives wings to the innovative idea of teaching science to preschoolers. Wry and distinctive visual humor, charming plotlines, and lovable characters combine with a comprehensive science curriculum to attract and engage kids three to five years old.

Great App but needs one little fix

This is a great game for kids. All the apps for Peep and the Big Wide World are the same ones you can find on their website but much easier to use on the iPad. The only problem is that if you ever hit the "i" button at the top right of the screen it puts you into an information screen that you cannot get out of. The only way we have found to get back to the game is to delete the app and reload it. We found this to be true for all of the games from Peep and the Big Wide World. Hope they get this fixed. But still these are all really great games. Just don't hit that button.

thank you for the ,

Great but...

I am ten years old and I still enjoy Peep and the Big Wide World. But I have a problem with all the iOS games. They always rotate sideways the moment you boot up the app, making it almost impossible to play. Can you please fix this bug?



This game supplied filament in our retirement home for our group o’ lovely old grannies. This was a big hit among those aged 70+! Thank you for the amazing game! -Ethel
