Curated OER
3-D Magnetic Field
In this magnetism worksheet, learners build a 3 dimensional magnetic field by using a juice bottle, a test tube, iron fillings and a magnet. Students write a descriptive story about what they observe once their bottle is complete and...
Curated OER
Safety Procedures Lab
In this safety procedures worksheet, students answer questions about eye safety, broken glass safety, lab area safety, chemical safety, fire safety and chemical disposal safety.
Curated OER
Sound/Pitch
Students explore how pitch changes when using instruments that are plucked, blown, and hit. In this sound and pitch lesson, students blow across the top of bottles that are filled with water to create sound. Students use recorders...
Curated OER
Crystals
Fourth graders use mucilage glue and magnesium sulfate to make crystals. They mix the ingredients, place a drop on a glass slide and observe the forming crystals.

Can Carbon Dioxide Act Like a Greenhouse Gas?
Ninety-seven percent of scientists who study climate agree that human activity is warming the planet. Learners explore carbon dioxide as a greenhouse gas, a gas causing this warming, through a hands-on experiment. Once complete, they...

A Microscale Acid-Base Titration
Watch as acids and bases put smiles on their faces. Young chemists learn the concept of acid-base titration firsthand in a microscale experiment. Working groups collaborate, titrate, then use their data to determine the concentration of...
Curated OER
Pollen Tube Growth
Learners demonstrate the proper usage of the compound and dissecting microscopes. They identify the parts of a flower and the functions of the flower parts. Students describe the process of gamete formation and fertilization in a flower.
Curated OER
Demonstrating the Kinds of Energy
Students experiment with inner tubes, weights, flasks, and pistons to demonstrate the gas laws. In this molecular motion instructional activity, students demonstrate pressure as a force per area. They conduct an experiment to show the...
Curated OER
Build a Thermometer
Students build a thermometer. In this weather lesson, students use red food coloring, rubber stoppers, and hard plastic tubing to build a thermometer. Students use their homemade thermometer to measure the temperature.
Curated OER
Exploring Rocks
Students recognize differences in the size, shape, texture, and color of different rocks. In this rocks lesson plan, students also learn and repeat back how a volcano erupts and make one out of a toilet paper tube.

Patterns and Fingerprints
Human fingerprint patterns are the result of layers of skin growing at different paces, thus causing the layers to pull on each other forming ridges. Here, groups of learners see how patterns and fingerprints assist scientists in a...
Curated OER
Air Pressure is Powerful
Students construct a barometer and collect data on the changes in air pressure. They work is small groups using plastic tubing, corks, and green food coloring. They then use a formula to convert inches of mercury to barometric pressure...
Curated OER
Rainsticks
Middle schoolers create their own set of rainsticks. Using a pattern they designed, they make the sticks out of tubing and toothpicks. They place a combination of dried beans and rice inside and then decorate the outside of the stick. ...
Curated OER
Water Hardness- Causes and Testing
Eighth graders examine what materials cause water hardness and the relative measure of water hardness in a two part lab activity. In part one, 8th graders add an assigned soap test solution to eleven different test tube solutions in...

Going up in Smoke
Don't let all your hard work go up in smoke. Pupils conduct an experiment to see the harmful effects of cigarette smoke. They observe how smoke changes the color of white wool and an indicator solution.
Exploratorium
Geyser
Although it requires a little extra preparation the first time you use this geyser demonstration, it can be used repeatedly once it has been constructed. This demonstration is useful in showcasing how heat leads to increased pressure and...

Measuring Rate of Water Uptake by a Plant Shoot Using a Potometer
How quickly does a plant transpire? Learners explore this question through measuring water uptake with a potometer. They time the movement of a bubble a set distance to understand the motion and rate of speed.
Exploratorium
Falling Feather
Whether or not Galileo actually dropped balls from the Leaning Tower of Pisa, this demonstration will solidly demonstrate that objects are accelerated at the same rate, regardless of mass. You will, however, need a vacuum pump and a few...
Curated OER
Chalk Chromatography
Your chemistry class is sure to love this experiment on column chromatography, as demonstrated with chalk sticks and felt tip markers. Pupils use sidewalk chalk (another inexpensive form of chalk stick) to demonstrate adsorption and the...
Space Awareness
Oceans on the Rise
Temperature rises and land disappears! Through a lab exploration, learners understand the effect of temperature increase on water similar to the effect of global warming on our oceans. As they heat the water in a flask, they measure the...

Atmosphere
Earth's atmosphere is full of different energies, from thermal to wind to electromagnetic radiation. Through the presentation, class members discover these energies and how they determine weather patterns.
Massachusetts Institute of Technology
Auroras
Learn the science behind one of the most beautiful acts of nature. A comprehensive lesson explores the causes and characteristics of auroras. The instruction also explains the differences among auroras and what the differences indicate...
