In this conversion factors worksheet, students convert 15 measurements from one unit in the SI system of measurement to another unit. Students show their work and indicate the unit of measurement. Conversion factors are given.

In this conversion factor worksheet, students convert 15 problems within the SI system of measurement. They show their work and indicate the proper units.

The "Bottled Bacteria" activity instructions are a bit unclear, but the remaining activities investigating limiting factors in ecosystems are well-written. Learners model the exosystem of a bear and a herd of deer. They set up a...

Who is not drawn to trading cards? In this lesson, junior ecologists create a trading card of an animal or plant from one of Arizona's biotic communities. Gorgeous sample cards are provided in the lesson plan as well as a plethora of...

As part of a unit on Arizona's biotic communities, young ecology learners create a map. They describe how humans and animals adapt in their habitat. They take notes and create graphic organizers from articles they read. Beautiful maps,...

Part of a unit on Arizona's biotic communities, this lesson focuses on the vocabulary to be used. Terms include biodiversity, topography, desert, hybridization, niche, and more! Youngsters will define these words from contextual...

Junior ecologists examine Arizona's biotic communities and research an animal or plant that is found in this community. In this lesson plan, learnerss write a narrative essay about their assigned animal or plant. They research online and...

Students complete an experiment with Alka-Seltzer and reaction rates. They control the rate in which gases are allowed to escape. They test their predictions and observe what happens during the experiment.

If any of the limiting factors in an environment change, both animal and plant populations also change. The video explains two different models of growth and the impact of limiting factors. It highlights the carrying capacity of an...

A very timely lesson looks at the social and political factors that affect the spread of disease. Using the 1918 Influenza Pandemic as a case study, pupils research factors that influenced the spread of the disease, including the role of...

Students define and compare/contrast abiotic and biotic factors presented while using web cameras on the Web World Wonders website.

Students examine abiotic and biotic factors. They define biotic and abiotic, categorize a list of items onto a Venn diagram, label various items from areas on the school grounds as biotic or abiotic, and diagram a magazine picture.

In this biotic and abiotic factors worksheet, students complete 20 various types of questions related to biotic and abiotic factors. First, they write the vocabulary word that best completes the sentence. Then, students state an example...

How does a population's habitat determine the size of that population? Teach learners about carrying capacity and limiting factors with an engaging roleplay activity. Class members pose as a colony of penguins who must gather food amidst...

Cell membranes and the factors that affect its integrity are studied, with Beet tissue used as the model. A poster to display findings of the permeability of the membranes would clarify understanding and also allow a layer of language...

Along came a spider, who sat down beside her. She screamed, but RJ wouldn't smash it because spiders are a limiting factor for other insects in an ecosystem. In this video, other common limiting factors for populations are listed....

Students identify the abiotic factors that influence a river or stream and the organisms that live in it. They measure several abiotic and biotic parameters to gauge water quality. Students examine the biotic environment by identifying...

What kind of experiment can your class do to how observe the environment effects on organisms? Groups design and conduct lab experiments to learn about the effects of the environment on aquatic organisms. Based upon knowledge gained...

What variables change heart rate? Young scientists observe the beating heart in Daphnia to understand these variables. They make changes in temperature, chemicals, and other factors as they graph the heart rates. Analysis questions help...

Collaborators sort a set of cards into biotic and abiotic categories. Then, as a class, they discuss their work and relate each of the abiotic components to climate change. Finally, they form a web of components by connecting those that...

Research the impact that changes in biotic or abiotic factors might have on an ecosystem. Debate for or against the changes and take action in the community. This resource ideally follows stream studies that young ecologists may have...

The clear cartoon style slides in this presentation contain details that affect population growth. Natural disasters and other external factors are listed as density independent factors, and density dependent factors, such as competition...

Ecology enthusiasts explore ecosystems with this instructional activity. They define vocabulary terms and write out answers to questions about distribution and abundance of life. They complete a chart comparing abiotic and biotic factors...

How do we predict future population growth? Young researchers investigate various factors affecting the size of our population. As they calculate and interpret graphs to determine factors that could potentially affect increases...
