As a bee scientist, students help a honey farm that has low honey production due to wasps. Students learn about bees, heredity and traits to determine which traits will help the bees defend their hives against the wasps. They then pick a new queen bee to pass on these traits to the bee colony.

Lesson Quiz Review
17.3 Darwin’s Theory: Natural Selection
Use the information below to review the correct answers on the Lesson Quiz.
1. Natural selection is the mechanism by which species evolve over time. Nature, or the
environment, determines fitness. Individuals with high fitness are more likely to survive,
reproduce, and pass their traits to offspring. Over time, this mechanism develops
adaptations in species, which are traits that help an organism survive in its environment.
2. Natural selection depends on several factors. A population must have a variety of
inheritable traits, some of which provide greater fitness, or a greater advantage in the
environment. More organisms must be born than can survive, and the individuals with
greater fitness are more likely to survive than those with lower fitness.
3. A fruit fly (an insect) and a fruit bat (a mammal) are distant relatives, and their shared trait
of eating fruit reveals very little about their evolutionary history. Nevertheless, they must
have had an ancient common ancestor, as do all pairs of living things.
4. Adaptations include any inheritable body structure or behavior that helps an individual
survive or reproduce in its environment. Many animals have adaptations for defending
themselves from enemies, and these behaviors are at least partially instinctive, meaning
they are inherited from generation to generation.
5. When environmental conditions remain constant, a species may remain about the same
from generation to generation. Natural selection occurs when the environment of an
organism changes. If the desert should become cooler and wetter, then the kangaroo rats
that could tolerate or thrive in the cool, wet climate would have greater fitness than the
others of their kind. The kangaroo rats with greater fitness would become more likely to
survive and reproduce, and their traits would become more common in the population.
6. The diagram shows that an ancestral bear gave rise to all 8 modern bear species, and did
so through several evolutionary lineages. As Darwin explained, the species developed
because different populations became isolated in different environments. Each population
developed adaptations that allowed it to thrive and reproduce in its environment.

If the Labster Lab does not work for you do this one!

Note: I made a mistake in the video: Question 11 correct answer is A and D.
Question 18 is not scoring correctly and you will receive credit in Aeries.

Turn this lesson in even if it say "in progress".

Note: answer to question 6 is d.

Observe the steps of pollination and fertilization in flowering plants. Help with many parts of the process by dragging pollen grains to the stigma, dragging sperm to the ovules, and removing petals as the fruit begins to grow. Quiz yourself when you are done by dragging vocabulary words to the correct plant structure.

Explore the processes of photosynthesis and respiration that occur within plant and animal cells. The cyclical nature of the two processes can be constructed visually, and the simplified photosynthesis and respiration formulae can be balanced.

Login to your Gizmo account and complete the photosynthesis investigation.
As a marine biologist students learn about photosynthesis to help scientists in Australia determine why the coral in the Great Barrier Reef is bleaching.

Adjust the concentration of a solute on either side of a membrane in a cell and observe the system as it adjusts to the conditions through osmosis. The initial concentration of the solute can be manipulated, along with the volume of the cell.

Explore a wide variety of cells, from bacteria to human neurons, using a compound light microscope. Select a sample to study, then focus on the sample using the coarse and fine focus controls of the microscope. Compare the structures found in different cells, then perform tests to see if the sample is alive.

As a national park ranger, students must restore the ecosystem of a park back to normal. They interact with populations of many organisms including wolves, deer and bees. Students learn the importance of food chains and webs, and how human factors can impact the health of an environment.

Prairie Ecosystem
Observe the populations of grass, prairie dogs, ferrets and foxes in a prairie ecosystem. Investigate feeding relationships and determine the food chain. Bar graphs and line graphs show changes in populations over time.

Observe the population of rabbits in an environment over many years. The land available to the rabbits and weather conditions can be adjusted to investigate the effects of urban sprawl and unusual weather on wildlife populations.

Explore the abiotic factors that affect Caribbean coral reefs. Many factors can be manipulated in this simplified reef model, including ocean temperature and pH, storm severity, and input of excess sediments and nutrients from logging, sewage, and agriculture. Click "Advance year" to see how the reef responds to these changes.

Follow the path of a carbon atom through the atmosphere, biosphere, hydrosphere, and geosphere. Manipulate a simplified model to see how human activities and other factors affect the amount of atmospheric carbon today and in the future.

You have all week to complete this activity. Within this simulated region of land, daytime's rising temperature and the falling temperature at night can be measured, along with heat flow in and out of the system. The amount of greenhouse gases present in the atmosphere can be adjusted through time, and the long-term effects can be investigated.
