Density
Learners predict when an object will float or sink based on comparison of density of the object to the density of the substance in which it is placed. The access a website and sketch the object in the first column of their table and then...

Eyes on Dissolved Oxygen
Learn about the factors that affect the way oxygen dissolves in salt water with a chemistry lab. After studying the molecular structure of water, young scientists figure out how aeration, temperature, and organic waste affect dissolved...

Photons in the Radiative Zone: Which Way Is Out? An A-Maz-ing Model
Can you move like a photon? Young scholars use a maze to reproduce the straight line motion of a photon. The second in a six-part series of lessons on the sun has learners measure angle of incidence and refraction to determine the path...

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.

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
Middle schoolers analyze given data on density and diameter of objects in space by graphing the data and then discussing their findings. This ninth installment of a 22-part series emphasizes the Galilean moons as compared to other objects.

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...

Air Pressure
Learners participate in a series of demonstrations about Bernoulli's principle. They explain how air pressure varies with air speed. They write a detailed lab report about the activity. This is a great way to explore this concept.

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.
University of Colorado
Terra Bagga
One way to identify possible volcanic activity on other planets is by testing the planet for magnetism. A science instructional activity begins with pupils constructing their own planet from a dead battery, magnets, paper, and...

Catapult
Studying levers couldn't be more exciting! Learners build their own catapults and test the results as they make adjustments to the fulcrum. They compete against other groups to create the most accurate apparatus.

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.
University of Colorado
Modeling Sizes of Planets
The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

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,...

Beam Focusing Using Lenses
Explore optics using an inquiry-based experimental approach! Young scholars use a set of materials to design and build a unit capable of focusing a beam of light. They experiment with different lenses to determine the best approach to...

Amounts of Dissolved Oxygen in Various Bodies of Water
Students test water to determine the dissolved oxygen content while displaying the proper use of testing instruments while visiting water testing sites. They determine if the amount of dissolved oxygen is appropriate for the tested...
