Terms to know!!!!

Use the chromebooks to write down key words & their definitions onto more study cards!
WORD/CONCEPT on ONE SIDE, DEFINITION on the BACK I’ll give you extra credit if you still have your old homemade study cards from bio-evolution! Go to THIS QUIZLET: google “QUIZLET” and in the search bar type: “hey_mr_mason” look for 8th science food web energy OR webenergyabioticbiotic-factors-aaps-flash-cards/

Skip the terms: “tertiary consumer” and “commensalism”

What’s the difference between biotic & abiotic?

Biotic or Abiotic? Biotic!

Biotic or Abiotic? Abiotic!

biotic or abiotic?

Can you spot the biotic and abiotic parts of this diagram?

Biotic or Abiotic? Biotic!

Biotic or Abiotic? Abiotic! Unless you said the hand…

Biotic or Abiotic? Abiotic!

All living organisms are biotic or abiotic?

All living organisms are
BIOTIC!

All non-living parts of an ecosystem are
ABIOTIC!

What are all the biotic and abiotic things in this picture?

How do scientists classify ALL LIFE?
aka BIOTICS

HOW do we BEGIN?

HOW do we BEGIN? How did you classify the contents of your school bags & such?

We ORGANIZE it!

First, we have to CLASSIFY WHERE THINGS GO.

If you had to CLASSIFY life at BMS, how would you do it?
discussion point

Can you divide BMS into 2 big groups?

Can you divide BMS into 2 big groups?
ADULTS KIDS

Can you divide these 2 BMS groups into smaller groups?
ADULTS KIDS

Can you divide these 2 BMS groups into SUB-groups?
ADULTS KIDS TEACHERS ADMINISTRATORS PARENTS 6th GRADERS 7TH GRADERS 8TH GRADERS

Can we do it even FURTHER?

See how we can divide our grade-level groups even further into SUB-groups?
ADULTS KIDS 6th GRADERS 1. Pandas 2. Koalas 3. Mangroves 7TH GRADERS 8TH GRADERS HORNETS PANTHERS TEACHERS ELA MATH SS SCIENCE ADMINISTRATORS PARENTS

COULD WE BREAK IT DOWN EVEN FURTHER?
GETTING MORE SPECIFIC???

BIOLOGISTS use a TAXONOMY to CLASSIFY LIFE

Classifying all LIFE with a universal BIOLOGICAL TAXONOMY organizes LIFE down to the species!
KINGDOMS (the 5 kingdoms of life) PHYLUM (each kingdom broken down into dozens of phyla) CLASS (each phyla broken down further) ORDER (each class broken down into smaller “orders”) FAMILY (even more specific) GENUS (only the most closely related species here) SPECIES (only one SPECIFIC TYPE here!)

Pair ‘n’ share… What are the benefits of TAXONOMY?

Why a worldwide UNIVERSAL system? How many levels are there? Why have 7 levels? Is TAXONOMY FIXED and/or EVERCHANGING? The way we classify life doesn’t change, but the life we discover and life that disappears or evolves does!

How good are you at CLASSIFYING LIFE?

We will be looking at just the two BROADEST, most GENERAL classifications of life: Our 5 BIOTIC KINGDOMS and their PHYLA. KINGDOMS (the 5 kingdoms of life) PHYLUM (each kingdom broken down into dozens of phyla) CLASS (each phyla broken down further) ORDER (each class broken down into smaller “orders”) FAMILY (even more specific) GENUS (only the most closely related species here) SPECIES (only one here!)

show poster…

6-8 teams will compete for fun, knowledge, pride & prizes.

POINTS WILL BE AWARDED TO EACH TEAM FOR EACH ROUND.
There will be 2 rounds! POINTS WILL BE AWARDED TO EACH TEAM FOR EACH ROUND.

keep this in mind…. the OLDEST & MOST PRIMITIVE forms of life go at the TOP & TO THE LEFT of your taxonomy charts. the more RECENT, MOST ADVANCED forms of life go towards the BOTTOM & RIGHT of your charts

Your taxonomy chart should START like this:
MONERA MYCOTA CHYTRIDS NEMATODA SARCODINAS ANGIOSPERMS

FIRST IDENTIFY THE 3 ADDITIONAL KINGDOM CARDS
MONERA CARD MYCOTA CHYTRIDS NEMATODA SARCODINAS ANGIOSPERMS

Mr. G will group each student into 3-4 person teams.

EACH TEAM WILL ISOLATE THEMSELVES FROM OTHER TEAMS to avoid cheating!

EACH TEAM WILL ISOLATE THEMSELVES FROM OTHER TEAMS to avoid cheating! THEN, EACH TEAM WILL GET A COLORED POSTER AND 21 CARDS (3 kingdom cards, 18 phyla cards)

EACH TEAM WILL ISOLATE THEMSELVES FROM OTHER TEAMS to avoid cheating! THEN, EACH TEAM WILL GET A COLORED POSTER AND 21 CARDS (3 kingdom cards, 18 phyla cards) IF YOUR TEAM HAS THE PHYLA CARDS UNDER THE CORRECT KINGDOM, BUT IN THE WRONG ORDER, I WILL TURN THESE CARDS ON ITS SIDE. If they aren’t even in the right phyla, I will turn them upside down.

The 1st team to get all cards in the exact right spaces gets 5 points
2nd place gets 4 points 3rd place gets 3 points 4th place gets 2 points all other color teams get 1 point

WAIT TIL EVERYONE IS READY AND Mr. G says “GO”

Good luck…and intelligence!

Remember the birds & bees who pollinate flowers, what kind of advantage does this give these plants?

If you are a tree stuck on a mountain, which type will seeds travel farther?

Don’t flowering plants have GREATER RANGE to distribute seeds?

If you are a tree stuck on a mountain, which type would you expect more genetic diversity?

Think how much more mixing of genotypes happens when birds and bees help!

EXCERPTS FROM FIRST FLOWER?
