Thugainn a’ rannsachadh còmhla ri Piseag agus Cuilean! Tha Piseag agus Cuilean ag ionnsachadh mu dheidhinn Luath agus Mall. Tha iad a’ tòiseachadh an cuid rannsachaidh air bòrd roilear-còrsair. Chan eil Piseag a’ saoilsinn cus dhen roilear-còrsair nuair a tha e a’ gluasad gu mall suas bruach, ach tha i air bhioran nuair a thòisicheas e a’ gluasad gu luath sìos a’ bhruthaich. An uair sin, tha Piseag agus Cuilean a’ lorg diofar rudan a tha luath agus diofar rudan a tha mall. Le cuideachadh bho luchd-rannsachaidh òga, tha Piseag agus Cuilean a’ dearbhadh am bi càraichean mòra an-còmhnaidh a’ gluasad nas luaithe na càraichean beaga? Am measg a’ bheothachaidh, tha neach-rannsachaidh òg a’ siubhal gu mall ann an rocaid, ach nuair a phutas iad putan, tha an rocaid a’ dol nas luaithe.

Kit and Pup explore the opposites fast and slow. They start by jumping on a roller coaster. Kit is bored as a roller coaster slowly makes its way up the slope before getting excited as it moves faster down the slope. Kit and Pup then try and find as many fast and slow things as they can. In the live action investigation, Kit and Pup help the little investigators discover whether big toy cars always travel faster than small toy cars. And in the stop motion moment, a little investigator is travelling in a slow rocket before deciding to hit a button to make the rocket go fast. Show less
