Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

Who knew that learning about the states of matter could taste so sweet? This fun hands-on lesson captures the attention of learners as they use what they know about solids, liquids, and gases to create their very own batch of ice cream.

Winter weather offers a great opportunity to teach young scientists about the states of matter. This activity-based lesson includes a range of learning experiences, from experimenting with the rate at which ice melts...

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Start this mini unit on matter out by demonstrating how food coloring behaves when placed in cold and in hot water. Then have the class experiment with warm water and soap film. Pupils will learn that an increase in thermal energy also...

Do you think the lab smells like rotten eggs? Sorry to hear about your sulfering. A set of five experiments covers many different topics including seasons, gravity, food, precipitation, and photosynthesis. Though not presented as a...

It's time to get a little silly with this fun primary grade science activity. By simply combining two liquids, white glue and corn starch, a strange solid is formed, commonly known as silly putty. To ensure everything goes smoothly,...

Sometimes the simplest experiments leave the biggest impression! Introduce young chemists to the Cartesian Diver by having them make one of their own. Use the Diver to further their study of liquids and gases, as well as compression.

Enhance your states of matter lessons with a hands-on science investigation that compares six different balls' color, texture, size, weight, ability to bounce, and buoyancy. 

Explore the unique characteristics of polymers. A complete activity begins with a presentation introducing polymers. Following the presentation, young scientists develop a laboratory plan for creating substances using polymers. They...

Who can grow the best crystals? Challenge class members to develop strategies for enhancing growth in the crystals. Through a lab investigation, learners study the properties of crystals and test the effectiveness of different...

Fascinate young life scientists by showing them how their brain learns. By using prism goggles while attempting to toss bean bags at a target, lab partners change their outlook on the world around them, producing amusing results....

How does the dirt get out of your drinking water? A hands-on activity introduces the use of flocculants to help clear solid particles out of water. The plan walks learners through the process of setting up an experiment that...

Calories are not tiny creatures that sew your clothes tighter every night, but what are they? A science lesson, presented at multiple levels, has learners experiment with heat, heat transfer, and graph the function over time....

Tiny bubbles, in my...clouds? Offer youngsters a hands-on, visual learning experience when reviewing the scientific concepts of condensation, water vapor, and the collection of droplets that make up clouds.

The sun sends the earth 35,000 times the amount of energy required by all of us on the entire planet, every day. The fourth instructional activity in the 10-part series looks at how light energy from the sun transfers into thermal...

Why do experiments require a control? Guide scholars through designing an experiment to see what they can do to evaporate water faster with a lesson that stresses the importance of controlling all variables. The second activity...

I'm so cool! No, you're exothermic. This thermodynamics lab unit includes an introduction, teacher demonstrations, six labs that students rotate through each class day, homework assignments, application of knowledge, and...

Do you think chromatography paper suffers from separation anxiety? Young chemists make soap, slime, silly putty, and experiment with chromatography in this lesson. The material includes clear instructions for each experiment along with...

How long do fresh foods last in space at the International Space Station? Which foods perish quicker than others? How can astronauts preserve their foods to make them last longer in space? Young scientists test the rates at which...

What is a prism? A place for light waves that commit minor refractions! The thorough resource includes three hands-on investigations covering light reflection and refraction; mirrors, lenses, and images; and optical systems. Subject...

This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag...

If the area you live in is arid, or the preceding experiment in this unit didn't yield obvious results, use this one in place of it to help reveal where condensation comes from. The mini unit that this is part of a comprehensive...

Science is magic that works. Magical color-changing beads and a coffee can that follows voice commands are just two examples of magic tricks that rely on science. After completing a hands-on activity and an experiment investigating the...
