Biology Packet - Ecosystems Biomes Food Chains Food Web Trophic Levels PopulationsOur Biology Packet dives deep into the study of ecology.  This packet looks at organisms at the individual, population, community, ecosystems, and biosphere level. Students will also learn about the relationships between living organisms and their physical environment.

What is the difference between a biome, ecosystem, and habitat? What is the difference between a food chain and a food web? What are trophic levels? What is the energy pyramid? What is symbiosis? How do different species interact? What in the world is amensalism or antiobiosis?! These are some of the things we covered in our biology unit!

How We Started Our unit on Biomes: When we first did this unit, we started with an overview of the main biomes. The kids could come up with the names for all of them, though not the more specialized words (like taiga or chaparral.)  In our biology packet, we have several different notebook pages on the main biomes. The kids did the “fill in the blank” version as we highlighted some of the main features of each biome (there’s also one that is completely filled in, one that just has the biome name and students can write in their own information, and a matching page (which my kids did a couple of weeks later):

Biomes-Worksheets

In the packet, there are full-sized (8 1/2 by 11) photos of each biome.  I chose to print 4 per page which worked well for our needs.  I laminated them and cut them apart.

What are the major biomes?

  • Arctic
  • Alpine Tundra
  • Boreal Forest or Taiga
  • Deciduous Forests
  • Deserts
  • Grasslands
  • Tropical Savannas
  • Chaparral
  • Tropical Rain Forest

Biome-CardsAs we kicked off our unit, I had the kids choose a biome and they each did research and give a 3 to 5 minute speech on what they learned.  They actually loved that!  LD did deserts; DD did hers on the savanna; and ED did rain forests.

How We Started Our unit on Biomes (Part 2!): We are doing this unit again with my youngest (and middle daughter). This time, we are starting with some material on ecosystems first. I added in a new worksheet about ecosystems (in general). Then we will go over the terms biotic and abiotic (ie. the physical, nonliving factors that shape an ecosystem – things like light, water, temperature, etc.) … and we’ll talk about the factors (in a general way) that can affect an ecosystem:

What is an Ecosystem - Abiotic and Biotic FactorsThen we will go on to talk about the different biotic (living) and abiotic (non-living/physical) characteristics of each of the world biomes.

Biomes Sorting Cards: Recently, I added in some biomes sorting cards. Before we did this, we talked about the biotic (living) and abiotic (non-living) factors.  Then we did the sorting cards with biotic (animal and plant) cards and abiotic factors (soil, temperature, length of the winter/summer and so forth).

World Biomes - Biotic and Abiotic Factors Activity

World Biomes Worksheets Notebook Pages Cards & ActivitiesThere are also worksheets on the biotic and abiotic factors of each of the world biomes. There are matching pages as well as blank pages so students can write in their own answers.

My kids used the biomes cards as they filled out the chart on the right below.

Feeding Relationships & Biological Interactions

We learned the difference between food chains and food webs… and talked about the energy pyramid. The packet includes some interactive notebook activities:

Trophic Level - Interactive Notebook Activity

From there we discussed the difference between habitats and ecosystems. We talked about the difference between producers and consumers (autotrophs and heterotrophs).  And, we talked about the different feeding relationships: herbivores, carnivores, omnivores, detritivores and decomposers.

Biology-Feeding-Relationships

There are some self-correcting review cards for these terms as well:

herbivore carnivore omnivore decomposer detritivor cards

Life BBC DocumentaryOur unit would definitely not have been as amazing without the breathtaking footage and fascinating stories about the animals of our planet!!  We watched the BBC documentary Life (affiliate link) also narrated by David Attenborough as we studied the different biomes, feeding relationships and biological relationships.  This series was the perfect complement to our studies because it really looked in depth at “some of the more colorful strategies the world’s creatures employ to procreate, evade predators, and obtain nourishment. This enthralling BBC series examines “the lengths living beings go to to stay alive.” We highly, highly recommend this documentary:

We spent time talking about food chains, food webs, and the energy pyramid.

Food Web ActivitiesThere is also an activity about the Energy Pyramid:

Energy Pyramid Interactive Notebook Activity

In the last part of this unit, we spent quite a bit of time learning about biological interactions:

  • Amensalism
    • Predation
    • Competition
    • Antibiosis
  • Mutualism
  • Commensalism
  • Parasitism

We start with a general discussion of symbiosis and I also introduced the animal defense – mimicry. Then we go into more detail about the different biological relationships:  This relationship can be helpful to both symbionts, helpful to one but neutral to the other, or helpful to one but harmful to the other.  One or both of the symbionts might entirely depend on each other for survival or they might generally live independently.

Biological-Interactions-WorksheetsTo wrap up our unit, we reviewed many of the new terms we had learned about the Biosphere.  🙂  The kids (and I!!) definitely learned a lot! 🙂

Biosphere-WorksheetsThe kids spent one day on the anatomy of a cat and dog. You’ll find those sheets in this packet as well:

Animal-Anatomy-Pages

What age is the Biology Unit for? This unit is probably best for middle school or early high school. The first time we did this unit, my kids were in middle school (and my youngest was in elementary). I believe they were 12, 10 and 8 (For the most part, it was too challenging for my youngest/8-year-old at the time, though she loved the documentaries we watched and  participated in the hands-on activities). If you have younger kids, you might want to do the Animal Unit instead.).  We reviewed various concepts from this unit a couple of years later when my kids were 14, 12 and 10. My youngest (now age 13) will be doing this unit in-depth this coming fall and her sister (age 15) also wants to review some of this material because it was covered really quickly in her high school biology class a couple of years ago (We used Thinkwell Biology for high school biology).

Note: I wanted to let you know that I did a big update of the Biology Packet this summer.  I added well over 50 pages and have new materials on ecosystems and on populations and population growth.

In this unit, we started off by talking about why we classify things. We learned about the dichotomous key and did a number of activities to understand how they work. We talked about why classification is useful and how we can do that in a way that is organized and logical.

Scientific Classification- Dichotomous Key ActivitiesThen we went into more detail about the history of classification.  Scientists have been grouping and categorizing different species for most of human history. In the past 300 years or so, scientists have worked on developing a logical, organized system for classifying the species around us.

Animal Classification CardsAll living organisms are classified by their characteristics. We keep adding to and adjusting the classification system as new evidence become available through DNA research and molecular studies! We talked about Linnaeus and his contributions to the classification of animals and his system of naming organisms (binomial nomenclature).

History Scientific Classification - Linnaeus Notebook PagesWe talked about the current system of classification and by the end of the unit, the kids were readily able to identify the types of organisms that have been classified as Bryozoa, Platyhelminthes, Porifora and other phyla in the Animalia Kingdom.

Taxonomy-Scientific Classification-ActivitiesWe did a number of hands-on activities studying and observing various species and even did some simple dissections at the end of the unit.
