Mr. Robin Lyman's 7th Grade Integrated Science

Eisenhower Jr. High


Welcome to Quarter 1 of 7th Grade Integrated Science! 

We started the study of Botany at the start of this quarter.  Please note the instructions for the Quarter 1 leaf collection is due

Wednesday, Oct. 14, 2015

 

 

 

You need to make a leaf collection of woody plant leaves.  You have  given 2 dichotomous keys to indentify most of the native trees and most of the non-native ornamental trees.  For full credit, leaf collection must be from trees that are on the dichotomous key.  You will need 5 leaves from ten different species of tree.  (10 leaves for GT students) Herbaceous plant leaves, like tomato or squash leaves will not count for any credit.  The leaves must be from trees found on the keys.

Are the leaves whorled on the branch?

Is the leaf alternately placed on the  branch?

OR is the leaf placed oppositely on the branch?

Remember you need to press and dry the leaf between pages of newspaper or a notebook with some wieght on top of it. 

Mount the leaf with tape on a piece of paper and slide it into a sheet protector.  OR you could tape the leaf onto a posterboard.  The leaf MUST be protected, like with wide clear tape or plastic. 

Be sure to use your dichotomous keys that I Gave you... to identify the leaf / tree by Genus and species.  Also put both scientific names down (Genus & species), and the comnmon name. Genus name is capitalized but species is not capitalized.

This is an example.:

Norway Maple

Acer platanoides

Found at 4351 S. Redwood Rd. in Taylorsiville, UT

(extra credit for including the fruit)

This quarter we are also studying the Particulate Nature of Matter...or basic Chemistry...the below information is on Basic Chemistry:  states of matter, atoms and molecules, density, etc.

 

 

 

 

This includes the States of Matter:

 

 

 

 

 

Atoms=the smallest unit of matter with it's own identity and can not be divided under normal circumstance.  .  .  for example, a Hydrogen and a Helium atom:

 

 

Molecules = Two or more atoms bonded together...such as a water molecule; check out this website: 

The Periodic Table helps us understand the different types of atoms/elements.

http://utahscience.oremjr.alpine.k12.ut.us/sciber01/8th/matter/images/table.jp. 

Density = mass/volume

 

We'll be  studying  Geology

This unit includes the Layers of the Earth.

Inner Core, Outer Core, Mesposphere/Deep Mantle or just Mantle, Asthenosphere, Lithosphere/Crust 

Term project is making a model of the layers of the Earth OR making a poster of the layers of the Earth.  See Page 94 of the Holt Science textbook.

The below particles represent sorting in a streambed or lake.

silt

sand

pebbles

gravel

 

The order of particle sorting in a lake or stream bed is Gravel on the bottom, then pebbles, then sand, and then silt on top. 

 

We will also be panning for gold...well, fool's gold anyway. 

 

 

Later we, in Class, be working on Cells and Organs and Organ Systems...

Your Term Project is to make a poster of a plant and animal cell OR a model of a plant OR animal cell.  If you choose to do a poster you will need to do both a plant and animal cell.  Your project needs to be on poster size paper and drawn in color with the different organelles labled correctly.

 

This is ONE way to draw a plant cell. 

This is ONE way to draw an animal cell. 

 

This chart shows the Organization of Life.

You will soon start a project on this...with Chromebook computers. 

This chart ALSO shows the Structure or Organization of life.

You need to know about the different organs and their functions...you also need to know WHICH body system they come from...or Organ System...

 

 

 

 

 

 

 

 

 

DIgestive System

 

This is the Respiratory System

This is the Skeletal System...you only need to know that the bones are organs of this system...and perhaps a few bones like the skull, femur = upper leg bone, and the hurerus = upper arm bone.

This is the Excretory System that cleans the blood, makes and eliminates urine.

 

In the Nervous System you need to know that it includes the brain and motor nerves for sending messages to muscles for movement and sensory nerves to send sensory messages to the brain.

The main thing to know is that our muscles are what move our bodies...only Kingdom: Animalia have a nervous system and a Muscular System. 

We color code the Circulatory system...Arteries are coded red and they take oxegenated blood TO the cells and AWAY from the heart.  We color code the veins blue because they are carrying Carbon Dioxide back TO the heart & lungs and AWAY from the cells.  Arterial blood is a brighter red in color. 

 

Students also need to know a couple of BASIC things about the reproductive systems.  Namely that males make sperm cells in the Testes and Females make egg cells in the Ovaries.

 

 

 

 

 

 

 

NOTE: 2014-15 GT Students, summer project is at the bottom of this page due to all students from NEXT year needing all the the above information!

Insect ORDERS are listed and Illustrated.

Right Now In Integrated Science

We Sahara  quick unit on Botany & Paleontology and Classification of Life on Earth....

This is my latest drawing. It took 4 1/2 months to complete.  2 Tyrannosaurus rex vs. 2 Triceratops horridus. (Hey students, notice how I did NOT captitalize the species name?)  This drawing won 7th place in the 2010 Utah State Fair.   (Notice that the Genus name of "Tyrannosaurus" IS capitalized...the species name of "rex" is NOT capitalized.)

 

 

 

Genus: Smilodon, species: fatalis

by Robin Lyman

Triceratops Bull and Calf (Genus: Triceratops, species: horridus)

By Robin Lyman

NOTE:  Students, you need to learn that ALL living organisms have a Genus and species name...NEVER capitalize the species name.  I don't think you will be collecting any Triceratops or Smilodons for your leaf collection.

 

 

 

 

MR. LYMAN'S READING RECCOMENDATIONS:

I have readi the Alchemyst series...the story of the immortal Nicholas Flamel.  It is a VERY good series.  I have read The Alchemyst, The Magician, the Sorceress & The Necromancer....

 I loved The Ranger's Apprentice series.     I think it is REALLY well written!  The first book is called The Ruins of Gorland.

 

I  finished the Percy Jackson series a during the school year 2 yrs ago.

I thought the movie was OK for The Lightning Thief...

but seriously, it was only part of the story of the book and they even changed it some to make it a better movie story, but you REALLY cheat yourself if you don't read the book!  I have read the entire Percy Jackson Series and it is quite well done.  

 

 

 

I also finished reading the Fablehaven Series this past school year...I highly reccomend it to all my students and any parents who like fantasy literature!

 

Currently We are reading the "Janitors" series.

The following is especially useful for GT

7th Grade Science. 

You are  REQUIRED to do a Science Fair Project.

 

 

Steps of the Scientific Method: 

Problem: Identify a problem   For example:  "Few plants grow near the Great Salt Lake."

 Question:  Formulate a question about the problem:  For example:  "Why don't plants grow near the Great Salt Lake?"

 Hypothesis:  Write an IF, THEN hypothesis...for example: "IF I put plants in salt water THEN the plants will grow very poorly or die."    The Hypothesis is a prediction or best guess about what will happen in your experiment.

Procedure:(design a test of your hypothesis)  This should be done step by step and it is best to only change ONE variable in your experiment.  It is also best to have a control or control group ...so it is a true experiment. For example:  "Put 3 plants in water=control group, Put 3 plants in salt water=experimental group, observe plants on a daily basis."

 Results:  This is what happened...the collected data from your experiment.  NO explanation yet.

 Analyze Results: Analyze your data or results using charts and graphs.  Graphs are best done in color.

Conclusion:  You ACCEPT or REJECT your hypothesis and tell why then elaborate and answer your question.  For example:  "I accept my hypotheis because the plant in salt water grew very poorly as I had predicted, so few plants grow near the Great Salt Lake because plants can not tolerate salt water."

Report My Findings:  Share your experiment & what you learned.

These steps of the Scientific Method NEED to be displayed on your Science Fair board.

Boards are available for purchase from the School for $1.00.

BE SURE YOU ARE DOING A TRUE EXPERIMENT WITH A CONTROL OR CONTROL GROUP.

Here is another example, if you were testing the effect of different fertilizers on plants, you would buy several of the same plants.  ONE group of plants would have only water added to them.  This would be your control group.  You would test the other half of the plants by adding a fertilizer or fertilizers.  These would be you experimental groups.  Be sure to test only one variable.  So you would keep all the plants in the same room, at the same temperature, with the same amount of light etc.  ...because the ONLY variable you are testing is the effect of FERTILIZER, not the effect of light or temperature etc.

In the future, this website can help you in deciding what to so and in the planning of your Science Fair project.

7th Grade GT Class Summer Project Instructions:   Due 2 weeks after the start of school.   

For killing an insect you can use a "kill jar'...which is a cotton ball in a jar with a lid that fits tightly...or a jar that has plaster in the bottom. You soak the plaster or cotton ball with rubbing alcohol.   Be very careful with rubbing alcohol because it is poisonous if anyone drinks it.? So don't drink it!!!  You CAN do a paper collection by looking up and pasting pictures of the 20 different insects from at LEAST 5 differnt Orders.  The Orders are listed below. Click on the picture or box to see the full size picture.  

The below matches the handout you received on May 17th.   Your project is due by the second week of the 2014-15 school year.  Late projects will be worth less pts... -10% for each class period it is late.

Your insect collection needs to be made up of 20 insects from at least 5 different orders. INSECT ORDERS

 

   Orthoptera = Grasshoppers, crickets, & locust. Many produce sound by rubbing their wings or legs together.   They use vibrations to locate members of their own species.   Large hind legs are for jumping. They have cerci or tail appendages.

 Coleoptera = Bettles are the largest Order of insects with the most known species in the entire animal kingdom.  Around 25% of all known animals and 40% of all known insect species are beetles.  Beetles are sometimes considered “true bugs” with a broad, somewhat flattened body + 2 wings.   It includes ladybugs and what we in Utah call a stinkbug.   Beetles DON’T have a triangle on their backs.

 

Dragonfly.jpg

 

 

During the Carboniferous Period there was Meganeura, feautured in the BBC Production of Walking With Monsters.

Meganeura was 3 feet long. 

    Odonata = Dragonflies and Damselflies.  They have large eyes & 2 pair of wings.   They look a bit like a helicopter when in flight.  Both have long bodies and long wings.  Dragonflies wings are held horizontally somewhat perpendicular to the body when at rest.  Damselflies look like mini dragonflies when in flight but at rest the damselfly wings project over its back.   Both lay eggs in water with the larva stage preying on other insect larva.

   File:Diptera1.jpg  Diptera = Flies, gnats, midges, and mosquitoes.  There are 99,000 species worldwide and 17,000 species in North America.  They have one pair of membranous wings (count the wings).  Look closely at the photos because some members of Order:  Diptera look like bees and wasps because they are mimics.  They LOOK like a bee or wasp to scare the predators away.  The body often looks hairy…this is not true hair.  Note that the ONE pair of wings is a good way to tell mimic Diptera, (flies), from Hymenoptera., (bees and wasps)

    Lepidoptera = Butterflies and moths are similar, with some key differences you should note.  In general, moths have stout bodies with wings held “roof-like” over the body when at rest.  Butterflies have more slender bodies with the wings held upright when at rest.  Moth antennae are usually feathery and moths are more active at night.  Butterflies are more active during daylight hours and they prefer a warm sunny day.  Lepidoptera is the most famous order of insect for their great change during metamorphosis.  They start out as an egg on land or a leaf etc.  They hatch as a caterpillar, which is their larva form.  They then spin a cacoon and then emerge in adult form. 

 

    Neuroptera = Lacewings have 2 pair of very lacey wings.  Their larva vary from species to species. 

 

Hymenoptera = Bees, wasps, and ants.  Note that the waist gets very thin at the space between the Thorax and Abdomen.  There are 103,000 species worldwide and 18,000 species in North America.  They have 2 pairs of membranous wings.  The bee mimics…from Diptera…that look like Hymenoptera have only 2 wings and the fly waist does not get narrow like a bee or wasp or ant waist.  They often live in large colonies with a queen.  Many worker ants do not have wings. 

       Ephemeroptera = Mayflies can be identified by 2 – 3 projections on the tail.  Some species of adult mayflies live only 30 minutes.  Adults mate, lay eggs, and die.  Mayflies live up to a year as aquatic nymphs.  We, Mrs. Lyman and I, saw a bunch of these at our family reunion, this summer, near a creek in the Central Utah Mountains.

Dermaptera = earwigs.  They don’t really crawl into human ears.  They have some pincers on their tail and can pinch you quite badly when collected… if you are not careful.

 

Mantodea apparantly are NOT are illegal to collect! I just learned this from one of you this summer.   Praying mantis are preying on other insects so the spelling is tricky.  They are preying on other insects…but their typical stance LOOKS like they are praying…as in saying a prayer.  SO…the correct spelling is “P-R-A-Y-I-N-G. ”They catch other insects with their front barbed legs or arms.  They are a good form of biological control of other insects in gardens.  So, please do not collect these beneficial insects.  Even if it IS legal... If you want to submit a drawing or photo of one then that would be acceptable.  BUT I WOULD PREFER YOU  NOT  COLLECT THEM!!!!!!

Blattodea = cockroaches…tend to be brownish in color with a flattened body and very long antenna.  These insects are said to be nearly impervious to radiation. 

 

Hemiptera  These are also considered True Bugs.    They include cicadas, leaf hoppers, whiteflies, and aphids.  They have thicker front wings and membranous back wings.  So they have 2 pair of wings that look different.   This order includes plant bugs, squash bugs, and true stink bugs.  The local aphids are tiny and green and a great pest to farmers and gardeners.  One biological control for aphids is to introduce the predatory Ladybugs, (a member of Order: Coleoptera).   Look for the little triangle on the back to be sure you are looking at a Hemiptera.   Beetles don’t have it.

Trichoptera = Caddisflies.  They are a very unique insect order.  Eggs are laid in the water, then the larva stage often builds a small tubular caddis out of rocks or tiny sticks found in the water.  The larvae live in the water and prey on other insect larva.   So another species of insect in larva form will swim by and the caddisfly larva will pop out of the caddis to grab and eat the other larva.   The winged adults emerge for only a very short life…mate, lay eggs, and die.   They have a long youth but a short adulthood.
