In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

En esta actividad, los aprendices aprenderán que es la cromatografía y cómo usarla para separar diferentes sustancias - en este caso,usarán los colores.

This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

In this genetics activity, learners discover how to extract DNA from green split peas.

This is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.

In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.

In this activity, learners design a bungee jump for an egg using nylon stockings.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

In this activity, learners use Styrofoam to collect organisms from a pond, estuary or marine environment and then examine what they have caught with a microscope.

In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

In this activity (1st activity on the page), learners explore their sense of taste and the structure of the tongue by taste-testing various foods.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.

In this activity, learners will perform various investigations to understand the vestibular-ocular reflex and learn about the importance of visual cues in maintaining balance.

In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.
