Kõrv loodusesse - loodushelid ja helid looduses
Loodushelid ja helid looduses. Veebilehed info ja illustratsioonidega vastavatest liikidest, võimalik kuulata helindeid. Kõrv loodusesse kasutab kahte erinevat kokkusurutud helifaili formaati: mp3 ja real audio. Üldjuhul võimaldab mp3-formaat paremat kvaliteeti, kuid faili maht on suur. Real audio on väiksema failimahuga, kuid sellega kaasneb kehvem kvaliteet. Aeglase ühenduse korral on seetõttu otstarbekam valida real audio helindid. Kiirema ühenduse korral tasub kuulata parema kvalitee
TÜ Loodusteadusliku hariduse lektoraadi vastavatel kursustel (Loodusteaduste visualiseerimine) osalenud õpetajate koostatud interaktiivsed mudelid bioloogiliste protsesside tundmaõppimiseks. Kuigi mudeleid ei saa lugeda lõplikult viimistletuks, on nad õppeprotsessi visualiseerimiseks asjakohased: kasvõi ideede saamiseks. Kasutajal on soovitav fail enne oma arvutisse salvestada ning vajadusel täiendada.

California has always been a place of cultural interaction. Early California evolved and changed with each new group of settlers. These images depict the developing interconnectedness of California's early cultures. They also underscore the importance of movement and later settlement of peoples in California. Some of the modern images underscore the contested and often romanticized nature of California’s Spanish and Mexican heritage. This is a collection of primary source images.
Butterfly pupa anatomy
The pupa is the third stage of the butterfly's life cycle. The caterpillar creates a pupa, sometimes called a chrysalis, and emerges as the adult butterfly after metamorphosis. The butterfly's wings will be used for flying.
Blood flow of moving Lumbriculus
Observe blood flow and muscle contractions in each body segment of Lumbriculus variegates (note how blood flows in relation to the worm turning in the capillary tube).
Bee on flower
Bees visit flowering plants to collect nectar so they can store it as honey back at their hives. As a bee visits one flower after another, pollen collects on its entire body and especially on the legs. Bees help pollinate flowers while they collect nectar. This is a mutualistic behavior.
