In this activity, learners mix several sugar solutions to investigate the property of density. Each sugar solution has a different density and color of the rainbow.

In this physical sciences activity, learners explore how forensic investigators collect prints from a crime scene. Learners make hand impressions in damp sand and analyze the patterns they observe.

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

In this water activity, learners explore how water drops behave on different surfaces.

This activity (on pages 19-25) is about fleas and ticks, which are common pet parasites.

In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.

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

Use multiplication to help the aliens find out how much fuel they need to get their spacecrafts home.

In this activity, learners investigate the properties of graphene and graphite.

In this activity, learners make self-assembled polymer spheres.

In this activity, learners investigate what happens when you build up static electricity on plastic balls.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

In this game, learners explore the different sizes of things in the world. In this Twister-like game, learners must place a hand or foot on a circle of the right scale - macro, micro, or nano.

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

In this environmental health activity, learners grow and observe bread mold and other kinds of common fungi over the course of 3-7 days.

In this design challenge activity, learners investigate series circuits and motors to build a hand-held "kick stick." Their goal is create a battery-operated device that sends a Ping-Pong ball across

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

In this engineering activity, learners design and build a mechanical arm to lift a small item.

In this activity, learners play a matching game with their families to discover common inherited traits and traditions. Learners distinguish between inherited traits and learned traditions.

In this activity, learners separate the protein from milk and and use it to make their own glue.
