Wotchi ya Padziko Lonse Snyearth ndi wotchi ya padziko lonse yomwe imasonyeza nthawi ya mizinda pa mapu a dziko lapansi oyandama mumlengalenga. Kukhudza pamalo a mzinda kamodzi kumasonyeza nthawi ya komweko pa tray yomwe ili pansi. Mizinda iwiri kapena kuposa iwiri ikasankhidwa, kusiyana kwa nthawi pakati pawo kumasonyezedwa mwaokha. Wonya wowoneka ndithu wokhala ndi magetsi a LED amitundu yonse umawonetsa mitundu ya thambo mu nthawi iliyonse. Mkati mwa mapu a dziko lapansiwo, muli kuwala kochokera kumbali imodzi kosonyeza kusinthana kwa usana ndi usiku. Kuyandama kwake kumachitika mothandizidwa ndi ma magineti osasintha, ma electromagnets, ndi ma Hall sensor.

Werengani mafunso aposachedwa komanso zokambirana pamapangidwe, zaluso ndi luso pakati pa mtolankhani wa mapangidwe ndi akatswiri otchuka padziko lonse lapansi, akatswiri ojambula ndi olemba mapulani. Onani mapulojekiti aposachedwa komanso mapikidwe omwe adapambana Dziwani zatsopano pazapangidwe, nzeru, zaluso, kapangidwe ndi kapangidwe kake. Phunzirani zamapangidwe opanga opanga zazikulu.
