Melting Ice
Pupils observe the melting of ice and explore the basic physical changes that occur. They gain information of how different substances change the rate of melting. Students discuss the properties of water and ice, the definition of...

The Density of Liquids and Solids
There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

Analyzing Tiny Samples Using a Search for the Beginning Mass Spectrometry
Teach the basics of mass spectrometry with a hands-on lesson. The fourth in a series of six lessons explores how mass spectrometry measures the ionic composition of an element. Learners then compare and contrast relative abundance and...

The Moons of Jupiter
Can you name the three planets with rings in our solar system? Everyone knows Saturn, many know Uranus, but most people are surprised to learn that Jupiter also has a ring. The third in a series of six teaches pupils what is around...

The Invisible Sun: How Hot Is It?
It's getting hot in here! The first in a series of six lessons has learners model nuclear fusion with a simple lab investigation. Groups collect data and analyze results, comparing their models to the actual process along the way.
University of California
Hot! Hot! Hot!
Calories are not tiny creatures that sew your clothes tighter every night, but what are they? A science activity, presented at multiple levels, has learners experiment with heat, heat transfer, and graph the function over time. It also...

Freestanding Structures: A Tech Museum Floor Activity
Students attempt to design the tallest structure that they can with the given materials which are wooden dowels and rubber bands. They discuss the physics of their structure and how they would improve it the next time they built a...
University of Colorado
Terra Bagga
Earth's magnetic poles switch positions about every 200,000—300,000 years. In the activity, groups create a planet with a magnetic field. Once made, they use a magnetometer to determine the orientation of the planet's magnetic field....

Can Photosynthesis Occur at Saturn?
In the 19th activity of 22, learners determine if distance from a light source affects photosynthesis. Participants capture oxygen in straws and find that the amount of water the gas displaces is proportional to the rate of photosynthesis.
Chicago Botanic Garden
Carbon, Greenhouse Gases, and Climate
Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...
Curated OER
Magnet Circus
Students explore the properties of magnets by designing a device that can move as far as possible using only magnets to move it, and design a machine that will stay in motion for the greatest period of time.

Happy Landings: A Splash or a Splat?
Huygens spacecraft landed on Saturn's moon Titan in 2005, making it the farthest landing from Earth ever made by a spacecraft. In this hands-on activity, the 12th installment of 22, groups explore how density affects speed. To do this,...

Free Up the Ketchup!
Learners, in teams, use given materials and their knowledge of Newton's First Law to create a device that will remove a sticky ping pong ball from a 16-oz. cup (which represents ketchup stuck in a bottle.)

The Greenhouse Effect: Warming the Earth Experiment
First in a two-part lesson on the greenhouse effect, this lesson involves a classroom demonstration of the phenomenon, and a lab group experiment with color and absorption. Although there are easier ways to demonstrate the greenhouse...

What Is Heat?
If objects have no heat, how do they can gain and lose it? Scholars experiment with heat, temperature, and specific heat of various substances. They create definitions for these terms based on their own conclusions to complete the fourth...
Curated OER
Exploring Buoyancy
Students use materials found at a resource table to design simple devices that will house instruments to take water samples from a tub of water. They design 3 instruments, each varying in density so that one will float, one will hover...
Curated OER
Lead and Mercury Ion Catalase Inhibition
Students participate in a laboratory investigation in which they observe the effect of temperature and pH on enzyme activity. Students also examine exposure to heavy metal ions and the effect that may have on enzyme activity.

Petro Products
In this petroleum products learning exercise, students are given the components of crude oil and they graph the various products found in a 50 gallon barrel. Students complete an activity to determine if they have collected cards that...

Papermaking
Imagine recycling food scraps and using them to make paper. The directions are all here in a seven-page packet that details several paper-making strategies.
Curated OER
Spectroscopy Demonstrations
Students study light and see what emits photons and that light can be separated onto a spectrum. In this energy and matter instructional activity students identify gases using a spectrum chart.
Curated OER
Up, Up, and Away
Second graders observe the changes that water has when there is a change in a state of matter. In this lesson they observe the results of applying heat to water with the end result of conversion to a gas.
