Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

Young learners investigate and observe the properties of three liquids -- water, vegetable oil, and corn syrup. They use their senses to collect data and ask and answer questions.

In this art activity (page seven of the pdf), learners will use their creativity to make a "motion collage." Each student will be encouraged to draw a picture of something that moves to be a part of t

In this physics demonstration, learners will be surprised when a handkerchief holds water in an upside-down glass.

In this game-like activity (5th activity on the page), learners explore their auditory acuity as well as the importance of having two ears.

In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this activity, learners use their understanding of probability to guess which color will be drawn from a bag.

In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

In this activity, learners will go outside and create a constellation.

In this activity about gravity (page eight of the pdf), learners will very simply explore how gravity affects objects using balls and toys.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

In this hands-on botany activity, learners sprout vegetables in film canisters.

In this math activity, learners use non-standard measurement (paces) to find the distance from one point to another. Learners practice estimating and measuring distances .

In this activity, learners will explore basic information about thermodynamics by experimenting with ice. Learners will compare ice melting rates on metal pans or plastic cutting boards.

In this math activity, learners play a game similar to 20 Questions, in which learners must identify a secret number drawn from a bag.

In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.
