En båt som kantrar kan ibland sjunka ner till botten på havet. Vad beror det på? (Varför kunde regalskeppet Vasa sjunka när det var gjort av trä?)
Markera det rätta svaret.
Båten krossar ytspänningen Vatten kommer in i båten vilket gör den tyngre och den kantrar Vattnets kraft orkar inte hålla upp båten när den kantrar Varför är det lättare att spika in en tunn spik i en träbit än en tjock spik?

Ytan på spiken kan lättare tränga igenom träet, eftersom att spiken behöver inte tränga igenom lika mycket trä Den tunnare spiken får mindre friktion och det gör att den kan spetsa träet mycket lättare än en tjockare spik. Den tjocka spiken kommer att mosa träet Because physics!!!!!!!!!!!!!! Om en isbit smälter i ett glas vatten, vad händer med vattenytan?

Ytspänningen håller upp dig Saltet i döda havet håller upp din tyngd {"uid":"MxxZnVaizuigmlOG","settings":{},"pages":[{"pagehead":{"header":{},"text":{},"image":{},"audio":{},"video":{}},"questions":[{"uid":"XLsKaiditC5Fp7ss","header":{"text":"En%20b%E5t%20som%20kantrar%20kan%20ibland%20sjunka%20ner%20till%20botten%20p%E5%20havet.%20Vad%20beror%20det%20p%E5%3F%20%28Varf%F6r%20kunde%20regalskeppet%20Vasa%20sjunka%20n%E4r%20det%20var%20gjort%20av%20tr%E4%3F%29","size":20,"bold":false,"italic":false},"instruction":{"text":{"text":"Markera%20det%20r%E4tta%20svaret.","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{}},"answers":[{"uid":"buUSGRVVAwHHXfsu","text":{"text":"B%E5ten%20krossar%20ytsp%E4nningen","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{},"correct":false},{"uid":"5lWVoucutQvPcTF6","text":{"text":"Vatten%20kommer%20in%20i%20b%E5ten%20vilket%20g%F6r%20den%20tyngre%20och%20den%20kantrar","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{},"correct":true},{"uid":"Rp7KLpdyOxcZapNg","text":{"text":"Vattnets%20kraft%20orkar%20inte%20h%E5lla%20upp%20b%E5ten%20n%E4r%20den%20kantrar","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{},"correct":false},{"uid":"i4CaAx75gMP03NZO","text":{"text":"Jag%20vet%20inte","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{},"correct":false}],"randomizeLeft":true,"type":"MultiChoice"},{"uid":"K8vv8TuEA21on0zJ","header":{"text":"Varf%F6r%20%E4r%20det%20l%E4ttare%20att%20spika%20in%20en%20tunn%20spik%20i%20en%20tr%E4bit%20%E4n%20en%20tjock%20spik%3F","size":20,"bold":false,"italic":false},"instruction":{"text":{"text":"Markera%20det%20r%E4tta%20svaret.","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{}},"answers":[{"uid":"XuwGtXdqyMFhkwXe","text":{"text":"Ytan%20p%E5%20spiken%20kan%20l%E4ttare%20tr%E4nga%20igenom%20tr%E4et%2C%20eftersom%20att%20spiken%20beh%F6ver%20inte%20tr%E4nga%20igenom%20lika%20mycket%20tr%E4","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{},"correct":true},{"uid":"mQAC31RSHFTRwufN","text":{"text":"Den%20tunnare%20spiken%20f%E5r%20mindre%20friktion%20och%20det%20g%F6r%20att%20den%20kan%20spetsa%20tr%E4et%20mycket%20l%E4ttare%20%E4n%20en%20tjockare%20spik.","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{},"correct":false},{"uid":"mls3TmQlg1IZT9pu","text":{"text":"Den%20tjocka%20spiken%20kommer%20att%20mosa%20tr%E4et","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{},"correct":false},{"uid":"IQEW6GlWV8i2PEPx","text":{"text":"Because%20physics%21%21%21%21%21%21%21%21%21%21%21%21%21%21","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{},"correct":false}],"randomizeLeft":true,"type":"MultiChoice"},{"uid":"334OJdwVprTe6uIM","header":{"text":"Om%20en%20isbit%20sm%E4lter%20i%20ett%20glas%20vatten%2C%20vad%20h%E4nder%20med%20vattenytan%3F","size":20,"bold":false,"italic":false},"instruction":{"text":{"text":"Markera%20det%20r%E4tta%20svaret.","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{}},"answers":[{"uid":"ES1eaiN6UtJM6fO8","text":{"text":"Den%20h%F6js","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{},"correct":false},{"uid":"sD8MiolNavLyGRFd","text":{"text":"Den%20s%E4nks","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{},"correct":true},{"uid":"vQr8rHd2LzZk1RQT","text":{"text":"Ingenting","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{},"correct":false},{"uid":"9De9SW7ffbD3coTF","text":{"text":"Bryr%20mig%20inte%2C%20l%E5t%20mig%20dricka%20vattnet%2C%20jag%20%E4r%20t%F6rstig","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{},"correct":false}],"randomizeLeft":true,"type":"MultiChoice"},{"uid":"Ruf0nMoBAtM0yv1y","header":{"text":"Varf%F6r%20flyter%20du%20s%E5%20l%E4tt%20i%20d%F6da%20havet%3F","size":20,"bold":false,"italic":false},"instruction":{"text":{"text":"Markera%20det%20r%E4tta%20svaret.","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{}},"answers":[{"uid":"4olloA4OFqa0Onb2","text":{"text":"Vattnet%20%E4r%20varmt","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{},"correct":false},{"uid":"gTx0rVKzHKBk5973","text":{"text":"Ytsp%E4nningen%20h%E5ller%20upp%20dig","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{},"correct":false},{"uid":"B9ZTQkbhk6dIwMQb","text":{"text":"Saltet%20i%20d%F6da%20havet%20h%E5ller%20upp%20din%20tyngd","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{},"correct":true},{"uid":"LmkB8D4PcZAEZT8o","text":{"text":"St%E5r%20v%E4l%20i%20boken...","size":14,"bold":false,"italic":false},"image":{},"audio":{},"video":{},"correct":false}],"randomizeLeft":true,"type":"MultiChoice"}]}],"specialpages":{}}
