Learners design their own experiment to investigate how pollution diffuses through ground material.

In this activity, learners conduct scientific research on multitasking. Learners determine if multitasking with media while doing homework affects their ability to successfully complete the homework.

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.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this activity, learners examine their fingerprints and learn that they can be categorized by shape, but each fingerprint is unique.

In this genetics activity, learners create and decode a “DNA recipe” for a dog by randomly selecting strips of paper that represent DNA.

Exponga estos pósteres en el salón o déjelos donde los chicos los puedan explorar. Los chicos buscan las respuestas en libros de consulta o en línea.

In this activity, learners play a game similar to Tic-Tac-Toe. In this version, learners try NOT to get three-in-a-row. The player who gets three-in-a-row first loses!

Los Momentos de Mixing in Math son actividades de 5 a 10 minutos que mantienen a los chicos ocupados, aprendiendo sobre el mundo, y usando matemáticas por su cuenta.

Learners mark their traits for tongue rolling, PTC tasting (a harmless, bitter chemical), and earlobe attachment on tree leaf cut-outs.

In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.

En esta tira cómica, Mateo y Cientina emplean su conocimiento de la química y las medidas para esta actividad deliciosa - ¡hacer helado!

Jugando a este juego, los chicos desarrollan habilidades de lógica, geometría, y visualización espacial. Los jugadores empiezan con una red de hexágonos vacía.

In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.

In this activity, learners investigate soil conditions by creating a soil map. Learners record soil characteristics and compare the conditions of soil in different grid sections.

In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping.

In this genetics meets math activity, learners take inventories of their own easily-observable genetic traits and compare those inventories with other learners in groups.

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this activity, young learners use different-sized paper 'caterpillars' and various household items to predict and measure their height.
