In this math activity, learners use a variety of sensory modalities to gain experiences with identifying, describing and creating repeating patterns.
In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).
In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.
This fun hands-on astronomy activity lets learners use star maps (included) to find constellations and to identify stars with extrasolar planets (Northern Hemisphere only, naked eye).
In this activity about the baroreceptor reflex (BR) arc (page 123 of the PDF), learners discover the importance of maintaining adequate arterial blood pressure through a role playing exercise.
Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.
In this chemistry activity, learners will explore the concept of entropy. When learners stretch and unstretch a balloon, they will notice a change in temperature.
In this activity, learners make "solar cookies," edible models of the Sun's outer layers using sugar cookies and toppings.
In this biology activity (page 8 of the PDF), learners will determine whether they are "tasters" or "non-tasters", test selected individuals from their families and peer group for the trait, and chart
In this activity, learners make "totally tubular" forms of carbon. Learners use chicken wire to build macro models of carbon nanotubes.
In this activity, learners recrystallize substances from solutions and make observations about the resulting crystals. This test can help further identify the unknown.
This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.
In this activity about electricity, learners explore how static electricity can make electric "fleas" jump up and down. Learners use a piece of wool cloth or fur to charge a sheet of acrylic plastic.
In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.
In this activity (2nd on the page), learners conduct a series of tests to find out which foot is more dominant. In other words, are they right-footed or left-footed?
In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.
Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.
In this multi-part activity learners examine non-point water pollution.
In this online game, learners test their knowledge of human anatomy.
