In this activity, learners explore the relative size of the Sun and Earth as well as the distance between them.

In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

In this activity, participants will learn about how gigantic clouds of gas and dust in space, called nebulas, are formed. They'll create their own colorful model nebula using paint and a spinner.

This activity (on pages 23-27) lets learners simulate the work of scientists who take core samples of Earth's rocky layers to determine geological history.

In this activity, learners will imagine the challenges and opportunities of asteroid mining.

In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.

In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

In this activity (on pages 6-11), learners work as a team to investigate how impact craters on Earth, the Moon or other planets take shape and what patterns they make.

In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.

This activity gives caregivers and their children an opportunity to practice scientific ways of thinking that are developmentally appropriate for early learners.

In this activity, participants will learn how stars form from the dust and gas that exists in space clumping together.

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

In this activity, learners build a simple solar oven out of household materials to melt chocolate and marshmallow between graham crackers--known as s'mores.

In this activity, learners will create a magnifying glass called a waterscope, using water and household items, to examine various objects.

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

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

In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.

En esta actividad, los aprendices harán un terrario usando materiales simples.
