Acid Rain
Learners perform experiments to determine how different acids cause acid rain. They measure the pH of the water to calculate the water's acidity. They discover how acid rain dissolves rock materials.
Curated OER
Solutions and Suspensions
Students explore matter by conducting an in class demonstration. For this liquid mixture lesson, students identify the difference between a solution in which a solid dissolves into liquid, and a suspension where the solid doesn't...
Curated OER
Great Lakes Ecology
Students are able to use a secchi disk to measure the turbidity of water by determining the depth at which the sechi disk is no longer visible and using the data in a formula to quantify the results. They are able to use Vernier probes...

Changes In Matter, Not In Weight
Fifth graders investigate different objects and the examine the correlation of mass and weight. They conduct the experiment with the help of background information provided by the teacher and record observations before making...
Curated OER
The Human Organism
In this digestion and nutrition lesson, 3rd graders test foods to find their vitamin content. Students test for starch and fats then compare their findings on charts and oral reports. The lesson concludes with a teacher directed class...
Curated OER
Lesson 1 - What Are Fossils?
Students define and research fossils. In this fossil lesson, students access teacher assigned Internet sites to examine images of fossils. They determine the definition of a fossil and find out how fossils are formed. They also define a...
Curated OER
What's in the Water?
Students make a water sampler and use proper techniques to collect water.They write a essay explaining the inter-relationship of factors such as temperature, pH, dissolved oxygen, nitrates, and phosphates in a lake that might cause a...
Curated OER
An Egg-cellent Osmosis Experiment
Students investigate the problem of osmosis by conducting an experiment. They use eggs with the shells dissolved to tell whether fluid can move across the membranes. The experiment provides high interest for all kinds of students to keep...

Adsorption and Catalysis
Adsorption, not absorption, is when atoms stick to the surface of an object, like water sticking to a grain of sand. An informative lesson delves into adsorption, teaching physical and chemisorption and the factors that affect them....
LABScI
Cell Diffusion and Permeability: The See-Thru Egg Lab
Create a model to study a microscopic phenomenon. The seventh of 12 lessons uses an egg (without its shell) to represent a cell membrane. Using different solutions, learners explore the concept of cell diffusion. They monitor...
