“Exploring the Universe: Imagining Life” is a hands-on activity in which visitors imagine and draw an extreme environment beyond Earth, then invent a living thing that could thrive in it.

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.

In this collaborative storytelling activity, learners and caregivers develop a strong story about science and exploration.

In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.

Learners assemble a figure from a nylon stocking or sock stuffed with soil and seeds. The ends of the nylons inside the jar absorb water, which feeds the grass seeds.

We don't normally view people upside down and so our brains aren't accustomed to it.

In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

In this activity, learners will build ramps and test how the laws of physics apply do different objects. Learners will explore physics and cause and effect through this activity.

In this activity, learners discover that some plastics will shrink when you get them hot. Learners bake polystyrene in a regular oven and discover what happens.

In this activity, learners will explore the water cycle by creating a small atmosphere.

This science activity demonstrates the dominant eye phenomena. What does your brain do when it sees two images that conflict?

In this activity, the learner asks yes-no questions to identify a secret object (similar to Twenty Questions). This game is easy to adapt for different ages and different kinds of contexts.

In this self-measuring activity, learners observe and record how many times a minute they blink, take a breath, and chew, as well as how many times a minute their heart beats.
