After entering the pupal stage, the adult darkling beetle will emerge. The beetles can then mate and lay eggs, which will hatch into mealworm larvae.
This red algal cell (Chlamydomonas nivalis) gives mountain snow packs a red tint. It uses the pollutants in snow as food. It cannot be seen without a microscope.
Some animals are capable of concealing themselves against their surroundings. The patterns, colors, or behaviors they show that help them accomplish this are called camouflage.
Many animals (gophers, squirrels, rabbits, etc) dig holes to escape predators and for shelter against harsh environmental conditions, such as intense sunlight.
Join students as they observe mosquitoes in different stages of development and learn about the insect's life cycle in this video from Curious George.
For more than twenty years, making bee movies has been a part of the research work of professor Brian Smith.
Many times, an animal's only defense is speed and running away from predators.
Some birds, especially owls, produce pellets as waste. These pellets usually contain undigested fur and bones from whatever animal the owl has eaten. You can pick through these pellets to discover what owls eat.
Cacti have many thorns that prick potential predators if touched or eaten.
This activity will include the students observing the monarch life cycle inside the classroom, a field experience observing monarch life on a milkweed plant and drawing it, and back in the classroom students will make a pop-up book of the monarch's life cycle with a short description on each page.
Many organisms are in a constant predator-prey relationship with other organisms in nature. Over time, prey species develop specialized structures or behaviors to help them better survive against predation. This is called an adaptation.
Exercise is a vital component of staying fit and healthy. There are two main types of workouts. Cardio workouts work to maintain and strengthen the cardiovascular system and burn calories. Weight training workouts work to build muscle and tone the body so that it can move more easily and increase flexibility. Both kinds of workouts should be incorporated to lead a healthy lifestyle.
E. coli (Escherichia coli) cannot be seen with the naked eye and must be viewed under a microscope. Most strains are harmless and live in the human gut, but some strains can cause severe food poisoning.
Species that are not native in a particular area can change the food chain and the environment of the area. Organisms, called biological control agents, may need to be introduced to control the effects of the non-native species.
Objects underneath a microscope can reveal new views of the object that wouldn't be seen without a microscope's aid.
Imagine being the size of an ant. Be careful - a face-to-face encounter with an ant would be scary and potentially life-threatening! But, if you avoided being eaten, you could learn a lot about ant anatomy from a close-up view. Ants have many body parts that are normally hard to see without a magnifying glass or microscope. And each structure has its own special function.
Frogs eat insects, and frogs are in turn eaten by larger animals such as birds. Frogs hibernate, or more correctly, they estivate. During estivation, frogs lowers their body temperatures in cold weather and go into a kind of dormancy. Frogs can "migrate" in that they move across land to find ponds and water sources.
This activity is a classroom activity to invistigate seeds and plants.
Time-lapse photos or video show progressions from the start of an event to the end of the event. This photo illustrates a time-lapse view of the launch of a spacecraft and the support arm falling away as the craft launches.
Grass lawns need to be cut every so often because the grass will grow too long. Some weeds have adapted and grow back with the grass after being cut back.
