In this activity, learners use multiple thermometers, placed at different angles, and a lamp to investigate why some places on Earth's surface are much hotter than others.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

Bones are stiff, which helps us lift heavy things and walk around, but they are also somewhat flexible, which lets them bend slightly.

In this outdoor activity, learners investigate spider webs and feeding behavior, particularly how spiders trap food in their sticky silk webs while not getting stuck themselves.

Many people get water from a source deep underground, called groundwater.

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

Most of the time, we don't have to think about breathing. In fact, you're probably breathing right now without thinking about it!

Our bodies produce snot, or mucus, that we blow from our noses. In this activity, learners will create a model of how snot works and will explore how it keeps our bodies healthy.

In this activity, learners make their own solar oven to bake s'mores and learn about how solar energy is absorbed on Earth.

In this activity, learners make a model of a one-way heart valve to investigate how a heart controls the direction of blood flow.

Doctors often send a sample of blood to a lab, to make sure their patients are healthy.

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

In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

Learners will explore the concept of angular distance, and investigate why the moon appears to be the same size as the sun during a solar eclipse, despite the sun being much larger.

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

In this activity, learners use binoculars (or a telescope) to identify and track sunspots. If using binoculars, learners need a pair that can be secured on a tripod.

In this card-based personal choice activity, learners review and sort COVID-19 and vaccine science information.

In this movement and measurement activity, learners jump as far as they can three times, and compare their longest jump to the longest jump of their friends, classmates and/or family members.
