Explaining Greater Diversity - 2nd Grade Science

Which observation best shows greater diversity: more of one species or more different species?

More different species. Diversity counts types, not total numbers of one type.
Which measure is better for diversity: number of species or number of individuals?

Number of species. More species means more diversity, regardless of individual counts.
Identify the best conclusion: A has $4$ kinds and B has $6$ kinds. Which habitat has greater diversity?

Habitat B. $6$ kinds is greater diversity than $4$ kinds.
What is biodiversity (diversity) in a habitat?

The variety of different living things in a habitat. Diversity means many different types, not just many individuals.
What is a fair test when comparing habitat diversity?

Compare habitats using the same method and conditions. Fair tests keep all variables the same except what you're measuring.
What is evidence in science?

Observations that support a claim. Evidence must be observable facts that prove or disprove something.
What does it mean if a habitat has many different plants and animals?

It has high diversity. More species types means higher biodiversity.
Which count is most important for diversity: number of individuals or number of kinds?

Number of kinds (species). Diversity measures variety of species, not population size.
Identify the best evidence to support a diversity claim: a photo, a list of kinds seen, or a personal opinion.

A list of different kinds seen (recorded observations). Written records provide specific, countable evidence of variety.
Identify the best comparison rule: should you observe the same size area in each habitat?

Yes, use the same size area in each habitat. Same area size makes the comparison fair.
What is a habitat?

A place where a living thing lives and gets what it needs. Living things need food, water, shelter, and space from their habitat.
Which habitat has greater diversity if A was sampled in a small area and B in a large area, even if B shows more kinds?

You cannot tell; the area size was not the same. Different area sizes make comparison unfair.
What does the word species mean in a simple classroom study?

A kind or type of living thing. Each species is a group of similar organisms.
What evidence should you use to compare diversity between two habitats?

Counts of different kinds of living things observed. Count each different type you see, not total individuals.
Which statement is a complete evidence-based explanation of greater diversity?

The habitat with more different kinds observed has greater diversity. Complete explanations connect evidence to conclusions.
Identify the habitat with greater diversity: Garden has bee, butterfly, worm, bird; Parking lot has pigeon only.

Garden. 4 different species vs. 1 species shows clear difference.
Which sentence uses evidence correctly: "A is diverse" or "A is diverse because I saw 8 kinds of organisms"?

"A is diverse because I saw 8 kinds of organisms.". Evidence-based claims include specific observations.
Which habitat has greater diversity if A has $12$ animals of $2$ kinds and B has $8$ animals of $4$ kinds?

Habitat B. $4$ kinds is more diverse than $2$ kinds, regardless of totals.
Which habitat has greater diversity if you observed $6$ kinds in A during $10$ minutes and $6$ kinds in B during $5$ minutes?

You cannot tell; the observation time was not the same. Different observation times make comparison unfair.
Which habitat is more diverse: Forest has 4 kinds of trees and 2 kinds of animals; Field has 2 kinds total?

Forest. 6 total kinds (4+2) is more diverse than 2 kinds.
What does it mean if a habitat has greater diversity than another habitat?

It has more different kinds of living things. Greater diversity means more variety of species, not more individuals.
Identify the best way to explain your choice: "Habitat A is better" or "Habitat A had more kinds observed."

"Habitat A had more kinds observed.". Specific observations justify conclusions; opinions lack evidence.
Choose the correct conclusion: A has 5 kinds seen, B has 5 kinds seen. Which has greater diversity?

Neither; they have equal diversity based on the observations. Same number of species means equal diversity.
Which option is better evidence for diversity: "I like Habitat A" or "I saw 7 kinds in Habitat A"?

"I saw 7 kinds in Habitat A". Numbers provide measurable facts; opinions aren't evidence.
Which habitat has greater diversity: A has 10 birds of 1 kind, B has 2 birds each of 5 kinds?

Habitat B. 5 different kinds beats many of just 1 kind.
Choose the correct evidence statement: A is more diverse because it has $6$ kinds; B has $6$ animals total.

A is more diverse because it has $6$ kinds. Kinds count diversity; individual totals don't matter.
Which observation should be counted for diversity: two robins and one robin, or a robin and a squirrel?

A robin and a squirrel. Different species count for diversity; duplicates don't add variety.
Which claim uses evidence correctly: "B is more diverse" with evidence "B has $2$ more kinds than A"?

Correct: B is more diverse because it has $2$ more kinds. Evidence correctly shows B has more kinds.
Choose the word that completes the claim: "Habitat A has _____ diversity than Habitat B" when A has fewer kinds.

less. Fewer kinds means lower diversity compared to the other habitat.
Identify the best comparison rule: should both habitats be observed for the same amount of time?

Yes, observe both habitats for the same amount of time. Equal time ensures fair comparison of what you might see.
Which option is the correct claim sentence: Habitat A has greater diversity because it has more individuals or more kinds?

Habitat A has greater diversity because it has more kinds. Diversity is about variety of kinds, not quantity.
Which observation is best evidence of greater diversity: more kinds or more of one kind?

More different kinds of living things. Diversity counts types of organisms, not quantities of one type.
Identify the habitat with greater diversity: A has 12 squirrels only, B has 6 squirrels and 6 birds.

Habitat B. 2 different kinds beats 1 kind, even with fewer total animals.
Identify the habitat with greater diversity: A has 4 kinds, B has 4 kinds.

Neither; they have the same diversity. Equal number of kinds means equal diversity levels.
Identify which habitat is more diverse: Pond has frog, fish, snail; Yard has ant, ant, ant.

Pond. Pond has 3 different species; yard has only 1 species.
Which option is better evidence for diversity: a guess or a recorded observation?

A recorded observation. Written records provide reliable evidence, guesses don't.
What is a species in simple terms for comparing habitat diversity?

A kind of living thing (for example, robins are one kind). All robins belong to the same species, even if there are many.
Which option is a fair comparison when judging diversity in two habitats?

Observe both habitats for the same amount of time. Equal observation time ensures both habitats get fair assessment.
What should you do if you cannot identify an organism but want to include it as evidence?

Record it as an unknown kind with a description or sketch. Unknown species still count toward diversity if documented.
Which is the best way to compare diversity fairly in two habitats during a class walk?

Observe for the same amount of time and record kinds seen. Equal observation time ensures fair comparison.
Which observation best shows greater diversity: more total animals or more different kinds of animals?

More different kinds of animals. Diversity counts types, not total individuals.
Identify the best conclusion: Habitat A has 6 kinds observed; Habitat B has 9 kinds observed.

Habitat B has greater diversity. 9 kinds exceeds 6 kinds, proving greater variety.
Which option is the best evidence that a habitat supports many organisms: many food sources or no water?

Many food sources. Food variety supports different organisms needing different diets.
Identify the better claim: "Habitat A is more diverse" or "Habitat A is more diverse because it has 7 kinds."

"Habitat A is more diverse because it has 7 kinds.". Good claims include evidence (the count) to support them.
Which option is the best way to show diversity with numbers: count total organisms or count different kinds?

Count the number of different kinds (species types). Species variety, not population size, determines diversity.
Which habitat has greater diversity if Habitat A has $7$ kinds and Habitat B has $4$ kinds?

Habitat A. $7$ kinds is more diverse than $4$ kinds.
Which habitat has greater diversity if Habitat A has $5$ kinds and Habitat B has $5$ kinds?

Neither; they have the same diversity. Equal number of kinds means equal diversity.
Identify which habitat is more diverse: A has kinds {ant, beetle, worm}; B has kinds {ant, ant, ant, worm}.

Habitat A. A has $3$ different kinds; B only has $2$ kinds (ant, worm).
Which observation supports higher diversity: "Many squirrels" or "squirrels, rabbits, birds, and insects"?

"squirrels, rabbits, birds, and insects". Listing 4 different species shows more diversity than 1.
Which habitat has greater diversity if A has $3$ kinds of plants and $1$ kind of animal, and B has $2$ plant kinds and $2$ animal kinds?

Neither; both have $4$ kinds total. Add all kinds: $3+1=4$ and $2+2=4$ , so equal diversity.
Which habitat likely has greater diversity: one with many plants, or one with almost no plants?

The habitat with many plants. Plants provide food and shelter for various animal species.
Which habitat has greater diversity: Habitat A has 6 kinds, Habitat B has 3 kinds?

Habitat A. 6 kinds is greater than 3 kinds, showing more diversity.
Which option helps make observations more accurate: guessing or using a checklist?

Using a checklist (or data table) to record organisms. Checklists prevent forgetting and ensure systematic recording.
Identify the evidence you should use to compare diversity between two habitats.

Observed list or count of different kinds of organisms. Counting different species provides measurable diversity data.
Identify the habitat with greater diversity: A has 8 kinds of organisms, B has 5 kinds.

Habitat A. 8 kinds is greater than 5 kinds, showing more diversity.
