Matter and Energy in Organisms and Ecosystems
Cellular Biology Lab

Cellular Biology Lab

Students lend a hand to scientists in the Cellular Biology Lab by checking out a simulation of photosynthesis in a spinach plant and cellular respiration in a rabbit and answering the scientists’ questions!
LabBench Cell Respiration

LabBench: Cell Respiration

In this laboratory, students will observe evidence for respiration in pea seeds by virtually building a respiromenter and investigate the effect of temperature on the rate of respiration. Close investigation teaches students about respiration at the cellular level.
Measuring the Photosynthesis of Elodea

Measuring the Photosynthesis of Elodea

In this virtual lab, students can measure the photosynthetic rate of Elodea. Students collect data as the Elodea photosynthesizes to explore the connection between varying distance from a light source and its effect on photosynthetic rate in a real species. This HTML lab will work on all devices.
Leaf Photosynthesis

Leaf Photosynthesis

Students are guided through multiple simulation situations and short answer questions as they use a model to explore leaf photosynthesis and the macroscopic outcome of the photosynthetic reaction. This will work on any device that is internet capable.
The Carbon Cycle

The Carbon Cycle

This lab uses a robust model of the carbon cycle to give you an intuitive sense for how carbon circulates through the atmosphere, biosphere, oceans, and crust. Students experiment with how human input to the cycle might change global outcomes to the year 2100 and beyond.
Photosynthesis Interactive

Photosynthesis Interactive

Learn how photosynthesis works by performing the light-dependent reactions and the Calvin cycle yourself. It this interactive, the biochemistry of photosynthesis comes alive! Also, learn about the anatomy of the leaf and where exactly the reactions of photosynthesis take place.
Model Ecosystems

Model Ecosystems

In this exploration, students will study and analyze five simplified model ecosystems. Students analyze the data of population numbers and energy amounts by calculating the conversion efficiency of each trophic level.
Photosynthesis Virtual Lab

Photosynthesis Virtual Lab

In this Virtual Lab, students will perform an experiment to investigate what colors of the light spectrum cause the most plant growth. Students make measurement comparisons and interpret graphs to prove/disprove their hypotheses.

Global Maps

NASA satellites give us a global view of what’s happening on our planet. Explore how key parts of Earth’s climate system change from month to month. Variables like carbon monoxide, chlorophyll, cloud fraction, radiation, surface temperature and so much more are all visually represented!

Food Chain Gizmo

Just like in the real world, the populations in this online ecosystem can be studied as part of a food chain while disease and population size can be manipulated by students. This is a free subscription site, and you are able to see this Gizmo for 5 minutes. Shockwave is required.

KEY CONCEPTS

Organization for Matter & Energy Flow in Organisms (LS1.C)

  • Plants, algae, and many microorganisms use the energy from light to make sugars (food) from carbon dioxide & water through the process called photosynthesis. (MS-LS1-6)
  • Within organisms, food is broken down by chemical reactions to form new molecules, support growth, or to release energy. (MS-LS1-7)

Interdependent Relationships in Ecosystems (LS2.A)

  • Organisms and their populations are dependent on environmental interactions with both living things and nonliving factors. (MS-LS2-1)
  • In all ecosystems, all organisms compete with each other for limited resources. (MS-LS2-1)

Cycle of Matter & Energy Transfer in Ecosystems (LS2.B)

  • Food Webs are models that demonstrate how matter & energy is transferred between producers, consumers, and decomposers, as these three groups interact. (MS-LS2-3)
  • Ecosystems are dynamic in nature; their characteristics vary over time. (MS-LS2-3)

Energy in Chemical Processes & Everyday Life (PS3.D)

  • Cellular respiration in plants & animals involve chemical reactions with oxygen that releases stored energy. (MS-LS1-7)

About NGSS

Next Generation Science Standards is a multi-state effort to create new education standards that are “rich in content and practice, arranged in a coherent manner across disciplines and grades to provide all students an internationally benchmarked science education.”
