Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

In this colorful activity (page 6 of the PDF), learners will make a multicolor density column by using different concentrations of sugar solutions.

Learners conduct an experiment to determine the rate at which two materials, sand and water, heat up and cool down.

In this water activity, learners discover ways to move water across the water table.

This activity was designed for blind learners, but all types of learners can explore the three states of matter by examining tactile models that illustrate the characteristics of particles in each sta

In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

Learners observe a sealed test tube containing a small amount of solid stearic acid.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.

In this hands-on activity, learners determine the types of chemical reactions achieved when combining different household products.

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

Everybody loves bubbles, and this is the best bubble recipe ever!

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

In this "Sid the Science Kid" activity from Episode 109: The Perfect Pancake, learners make applesauce to explore irreversible change.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.
