No glue is needed for learners of any age to become marshmallow architects or engineers.

Learners work in groups to build model cars from paper parts. First, each learner builds cars individually and the group times themselves.

In this math activity, learners create a magic turtle where all the rows, columns and diagonals add up to fifteen.

In this math activity, learners play a game and identify patterns with fun moves and sounds. Discover how dancing and signing involve patterns.

In this activity, learners grow germs collected from their hands and other objects. They cultivate the germs on a growth medium (such as slices of grapefruit or processed cheese) for a week.

In this math activity, learners use problem solving skills to find a middle seat for Mary at the movies. Learners practice dividing numbers and identifying the middle of a quantity.

In this engineering activity, young learners investigate multi-level buildings.

Choose a recipe to double (or triple, quadruple, or halve). Show everyone the recipe and engage them in figuring out: How much will we need to increase the recipe to feed everyone?

Esta actividad enseña la proporción y razón por hacer que los aprendices hagan "ensaladas" que combinan tres tipos de frijoles en tres combinaciones diferentes.

In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

In this activity, learners explore density and buoyancy as they design and construct rafts.

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.

Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

In this activity, learners compare the number of letters in the names of the people in their families or group of friends.

In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

In this activity about cartography, learners work in teams to create two different map projections: a planar (or polar) and a cylindrical (or Mercator) projection.

In this very hands-on lesson, learners will investigate dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible

In this activity, learners arrange triangles together to make patterns to create paper quilts. Learners experiment with arranging the triangles in different ways to make various designs.

In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

In this two-part math lesson, learners investigate problems that foster algebraic thinking across content strands. In the first part, learners explore even and odd numbers linked to quilts.
