Photosynthesis—Life's Primary Energy Source
Wouldn't it be great if you could produce your own food? Scholars learn about the processes of photosynthesis and cellular respiration in plants. They consider how to use photosynthesis as a model of an efficient system and how to apply...

Copycat Engineers
It's often said that imitation is the sincerest form of flattery. Young engineers learn about biomimicry, which uses nature to generate engineering ideas, in the fifth lesson of nine in a Life Science unit. Working in groups, they select...

Coloring the Life Cycle of Fruits and Vegetables
Students investigate how fruits and vegetables change and grow. In this life cycle of fruits and vegetables lesson, students observe the changes in fruits and vegetables as they grow and record the colors on a worksheet.
Curated OER
Mitosis & Cell Processes
Learners research the process of mitosis and how it progresses to the finished result of cell division. They reflect upon how this causes organisms to grow larger and helps tissues to be renewed.

Cell Organelles and Their Functions
Young scholars will be using Inspiration, which is a graphic organizer computer program, to create their own model community where they will label the community parts with the corresponding organelle. They will have prior knowledge of...

An Inquiry into Alcoholic Fermentation
Introduce life science students to their new "best buds" yeast! Using a wide variety of materials, lab groups design an experiment that illustrates how yeast acquires the resources it needs to undergo cellular respiration. The teacher's...
Pace University
Grade 6-8 Living Things
What characterizes a living thing? Scholars explore the concept during a differentiated instruction unit on living things. They perform lab experiments to determine how animals adapt to stimuli, watch videos and learn about...
Curated OER
Human Embryonic Stem Cells
Students use the Internet to discover information about human embryonic stem cells from the National Institutes of Health. They examine different sides of the debate to use or not to use stem cells. They can also listen to speeches given...
Curated OER
Spotlight On Stem Cells
Students discover the differences in how stem cells develop and function depending on their source. They see how scientists are using stem cells - from a variety of sources - to study how they can be used to cure certain illnesses and...

Student Cancer Journals -- Personal Reflections and Research on Life and Death Issues
Concepts learned in the study of mitosisand biochemistry help when making life or death decisions. Compile a notebook or portfolio of work related to the project can make the research more organized and relevant.
Curated OER
How Do Cells Reproduce?
Learners examine cell division and the process of mitosis. In this cell reproduction lesson students grow yeast and observe the results, and learn about the career of scientific illustration.

What Does Life Look Like Under a Microscope?
Students discover cells make up all living things. In this life science lesson, students investigate living organisms and the cells that create them. Finally the students create a testable question, conduct an investigation, and draw...

DNA Extraction from Strawberries
Has your class ever been astounded by the complexity of DNA analysis? Have they ever asked why genetic engineering has become so important to our daily lives? Young scientists perform DNA extraction on strawberries and explore how the...

Pasta Genetics
Four different-shaped and dyed pasta types represent four different alleles. Following a guide sheet, young geneticists practice randomly selecting alleles and discover the traits of the resulting offspring. This is a fun and solid...

Is Yeast Alive?
Through two investigations, life science learners determine whether or not yeast is alive. They perform tests for metabolism by providing sugar and observing if gas is produced as a byproduct. They incubate some of the sample for at...

Invisible Life
By setting up an aquarium in the classroom, learners are able to describe some macroscopic and microscopic organisms that are found inside. This well-designed, and educationally rich lesson requires pupils to use microscopes to view...

DNA on Stick
Students experience a "hands-on" activity to get visual evidence of the physical nature of DNA and the process of DNA purification. They explore one method of chromosomal DNA isolation and DNA extraction.
Nuffield Foundation
Investigating the Effects of Biochar on Soil Fertility
Breathe some new life into charcoal. Scholars use biochar to improve soil fertility. They test the effectiveness of this addition by conducting an experiment with soil having 0%, 2%, and 4% biochar.
Curated OER
Plant and Animal Cells - Are they Different?
Students observe the similarities and differences between plant and animal cells. In this cell activity, students use microscopes to observe self prepared slides of animal and plant cells.
Space Awareness
Climate Zones
The climate at the equator is hotter than the climate at the poles, but why? The lesson goes in depth, explaining how the angles of illumination relate to the heating rate at different latitudes and seasons. Scholars use a strong lamp,...
Curated OER
Microscopic Water Life
Students use a light microscope to observe the organisms living in a sample of ocean or fresh water. Students create a drawing of the organisms that they observe. Students then discuss the different body plans of the organisms and the...
