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

In this simulation activity, learners act as parts of the circulatory system and discover how it serves as a transport system for food/nutrients, oxygen, carbon dioxide and waste.

In some parts of the world, lakes freeze during winter. In this activity learners will explore water’s unique properties of freezing and melting, and how these relate to density and temperature.

In this activity (p.3-4 of PDF), learners learn about disease transmission and antibiotic resistance.

This is an activity about acid-base reactions using eggs and vinegar. Learners place eggs inside a container of vinegar and leave to soak overnight.

In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.

In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.

Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).

In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.

In this quick activity (page 1 of the PDF under SciGirls Activity: California Fish), learners will build a simple Cartesian Diver in an empty 2-liter bottle.

In this activity, learners make self-assembled polymer spheres.

In this quick activity about pollutants and groundwater (page 2 of PDF under Water Clean-up Activity), learners build a model well with a toilet paper tube.

Learners conduct a "blind" taste-test of several types of enhanced or fitness water drinking water that has commercially added substances like vitamins, sugars, or herbs.

In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this activity that can be used as a lab or demonstration, learners use Lactaid® and lactose to demonstrate the concept of enzyme action.

In this activity, learners make edible T. rex teeth (with adult assistance). The treat is a white and dark chocolate covered banana on a stick.

This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?
