In this math lesson, learners arrange pattern blocks to create tessellations and to explore geometric patterns. Learners first explore making patterns with a variety of pattern blocks.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

Learners create an Incan counting device called a quipu (pronounced kee-poo).

In this math lesson (on Page 13), learners predict and simulate the likelihood of an event occurring.

In this chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.

In this art-related activity, learners make a coin rubbing—a process similar to what archeologists may do with ancient artifacts. This activity can be used in connection with a history or art lesson.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

In this game, learners are stuck in a right turn only world! Learners take turns rolling a die and moving their game pieces along the lines of a grid to get "home," by only making right turns.

In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping.

In this nighttime, outdoor activity, learners keep a record of what they see in the sky by drawing constellations, the Moon, and making note of the weather and conditions each day.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

In this physics crime lab or demonstration, learners pretend they are criminologists and must find the "muzzle velocity" (speed of the bullet as it leaves the gun) of a gun used to commit a crime.

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.

In this math-based activity, learners will experiment to find how height and angle affect spatter and then use this knowledge to solve a crime.

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

In this activity, learners discover that they can create a lens from a water drop. Learners test their lens by looking at words or pictures.

In this series of exercises, learners predict the conditions necessary for bacterial growth, test their predictions and at the same time practice the aseptic techniques and safety procedures needed wh

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.

This is an activity (located on page 3 of the PDF) about the mixture of materials in bone and how they affect its strength.
