In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

In this activity, learners make a model of the solid Earth's layers that's good enough to eat! Learners use tasty foodstuffs to simulate Earth's inner core, outer core, mantle, and crust.

In this activity, learners use a model for how fishing affects marine life populations, and will construct explanations for one of the reasons why fish populations are declining.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.

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

Albert Einstein proved that space bends around anything that has mass. This activity uses Jell-O's ability to bend around objects as a model for space bending around planets and stars.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.
