Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.

Using pipe cleaners, straws, and beads, learners explore the building blocks of life by creating their own model of DNA.

In this activity, learners will explore pendulum motion through scientific trials by using household items with different length strings.

In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

In this math lesson, learners identify, describe, and construct the five regular polyhedra.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

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 explore dinosaur skeletons, anatomy, and locomotion. Learners compare and contrast dinosaur skeletons and drawings.

This three-part activity consists of an activity that groups of learners develop themselves, a given procedure, and an optional demonstration.

In this quick optics activity, learners use a dim point of light (a disassembled Mini MagLite and dowel set-up) to cast a shadow of the blood supply in their retina onto the retina itself.

In this health activity (page 3 of the PDF), learners will discover why covering their mouth and nose while sneezing is so important.

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

In this activity (on pages 34-39), learners make a fairly detailed model of DNA using licorice and gumdrops.

In this activity, learners will be working with a sort of scientific magic, capillary action! They will set up 3 cups of water of different colors, connect them with paper towels and wait.

In this activity, learners design a crushing test and discover that identifying and controlling the variables may be difficult.

In this sensory activity, young learners explore chemical reactions by making their own play dough from home.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

Learners explore the physical properties of a variety of balls and how they bounce.

In this outdoor activity, learners become beachcombers as they walk on a sandy beach in search of evidence of life.
