Plants
Here is a one-hour activity that helps learners remember the parts of plants. Not only will the class learn about plant parts, they'll also discuss seed dispersal and plant growth. A celery experiment is used to show how plants obtain...
Rainforest Alliance
Stop and Smell the Flowers
It's a bird! It's a bee! Actually, it's your learners flying from flower to flower smelling their scents! Using paper flowers and essential oils, pupils flutter between flowers to use their sense of smell to experience how animals use...

Are You Concentrating?
Explore the importance of a concentration gradient in the rates of dissolution. Using the ocean ecosystem, learners study rates of dissolution around coral reefs. A hands-on experiment helps individuals discover the effects of changing a...
Beyond Benign
Enthalpy of Combustion
Learn the facts about types of wax! Partnered pupils determine the enthalpy of combustion for traditional paraffin candles, as well as soy-based candles. The activity focuses on calculations and compares the environmental impact of both...
Beyond Benign
Breaking the Tension
The tension builds as learners experiment in your classroom. The 17th installment in a 24-part series has scholars investigate the concept of surface tension. After discovering characteristics of surface tension, they add a compound...

Observing Osmosis, Plasmolysis, and Turgor in Plant Cells
Create the perfect conditions for osmosis. Young scholars use a microscope to observe plant cells exposed to distilled water or sodium chloride. They observe how osmosis creates turgid or plasmolyzed cells.

Investigating Transport Systems in a Flowering Plant
Some weddings have flowers in a unique, unnatural color to match the theme. Young scientists take part in this process to learn about the function of the xylem as they observe colored water moving through a flower. Then, they experiment...

Following Gene Transfer by Conjugation in Bacteria
After the lab, you'll be able to solve this analogy: Natural selection is to vertical transfer of genes as ___ is to the horizontal transfer of genes. Young biologists conduct an experiment on E. coli bacteria to explore the process of...

Working with Immobilized Enzymes or Microscopic Organisms
Let the lab be a catalyst to learn about enzymes. Scholars create alginate beads filled with yeast. As part of an investigation into enzymes, they see how these beads provide a catalyst to the reaction of glucose into ethanol.

Heart of the Matter
Hands-on experience with valves and water flow supports young researchers' understanding of valve operation. Attached resources for learners are text-dense; I'd break up the text into smaller pieces for groups to read and present...
World Wildlife Fund
Land of the Midnight Sun
From days of 24 hour sunlight, to endless nights that last for days, the Arctic is a very unique place to live. Examine the seasonal changes that occur in the northern-most reaches of the globe and the impact they have on the plants and...
Aquarium of the Pacific
Lego Molecules
Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, learners build molecules based on the chemical formulas of common compounds.

Ink Analysis
High school chemistry class members become "detectives for a day" and use the concept of paper chromatography to analyze a note left at the scene of a crime. Pupils test the ink on the note with a solvent, such as isopropyl alcohol, to...
NOAA
Ocean Zones
How can organisms light up in water? Bioluminescence is light produced in a chemical reaction that can occur in an organism's body. First, learners determine what happens to light/color as you move into the deep ocean. In groups, they...
