Separation Anxiety
Source Institutions
In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.
Watching Crystals Grow
Source Institutions
Learners will compare the growth rate and appearance of crystals forming on small rocks to those growing on miscellaneous objects. Learners will also investigate how temperature (warm vs.
Composite Materials
Source Institutions
This is an activity (located on page 3 of PDF under Hockey Sticks Activity) about composites, materials made of 2 or more different components.
Chemical Change
Source Institutions
In this chemistry activity, learners explore the amount of copper in a new penny. Learners use toilet bowl cleaner to hollow out the interior of a penny with zinc inside.
A Swell Activity with Beans
Source Institutions
In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.
Percentage of Oxygen in the Air
Source Institutions
In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.
Ship the Chip
Source Institutions
In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.
Gravestone Weathering
Source Institutions
In this activity (located on pages 9-14 of PDF), learners visit a cemetery to examine the distinguishing characteristics of rock weathering.
Chemistry in the Kitchen
Source Institutions
In this kitchen chemistry activity, learners explore the chemistry of crystals by making sugar crystals, consider a common chemical reaction type responsible for the rising of muffins and cake in the
Lighting Up Celery Stalks
Source Institutions
In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla
Diffusion of Water with Gummy Bears
Source Institutions
In this activity, learners investigate the movement of water into and out of a polymer. Learners test the diffusion of water through gummy bears, which are made of sugar and gelatin (a polymer).
Gummy Growth
Source Institutions
In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.
Properties of Dust
Source Institutions
In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.
Plastic Milk: You can make plastic from milk
Source Institutions
In this activity (on page 2 of the PDF), learners make a plastic protein polymer from milk. Adding vinegar to milk causes the protein casein to solidify or curdle.
Pollution Patrol
Source Institutions
In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.
Cooling Off
Source Institutions
In this activity, learners are introduced to challenges of maintaining temperatures while living in space.
Nano Scavenger Hunt
Source Institutions
This is an activity (located on page 3 of PDF under Where's Nano? Activity) about identifying nanoscale objects and phenomena in today's world.
Making Recycled Paper
Source Institutions
In this activity on page 11 of the PDF, learners follow simple steps to recycle old newspaper into new paper.
Sugar Crystal Challenge
Source Institutions
This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.
Color-Changing Carnations
Source Institutions
Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.
