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...

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...

Never trust an atom; they make up everything! Young chemists make modeling dough and add another ingredient to change the properties. Scholars then compare the properties of emulsion to composite materials. A reading passage and analysis...

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. 

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.

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...

Instill the concept of adaptation with the help of Blubber Gloves—ziplock bags, shortening, and duct tape. Scholars discuss how animals and plants keep warm in polar regions, record their predictions, and try on their Blubber Gloves to...

Young scientists use electrolysis to separate water into its elements before experimenting with fire to learn about their properties. A helpful resource provides a reading passage and analysis questions. 

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

Adjust the melting time of ice without varying the temperature! Learners experiment with different materials to decide how the materials affect the rate an ice cube melts. They then connect their findings to the conductivity of each...

Geology rocks — literally! A geology chapter offers eleven activities at four different levels. Scholars enjoy completing hands-on experiments before applying critical thinking skills following a share, process, generalize, apply,...

Have some physical science fun when studying the center of gravity or center of mass. Simply have balancing artists stand a dowel on one finger and keep it from falling over! A lump of clay is added and moved up along the dowel over a...

Get hands-on in your physical science class by having learners conduct electricity with their own hands! By placing one hand on each of two different metals, a current can be generated and measured on a microammeter. Make an experiement...

Explore the properties of gases through one activity and two investigations in which super scientists observe the changes gas makes when encountering different conditions.

Learners will shout "Eureka!" in this quick but deep activity replicating the famous bathtub experiment of Archimedes. Given the scenario of a king with a suspected fake crown, young investigators develop formulas using density to...

Abracadabra! Provide your class with the tools to perform a chemical "magic show" as they predict the charges of various ions, determine ionic compound formulas, and make observations to determine when a chemical reaction between...

Learners work collaboratively to predict what life would be like as an Arctic Hare. Teams go on a hunt where scholars role play an owl, white hares, and gray hares. Independently, pupils record their findings and reflect on their...

We all know someone who won't eat the banana with a brown spot, the grape with a dimple, and the apple with a bruise. Scholars use different fruits to explore what happens when fruits really start to decompose. They set up an experiment...

Who's your Daddy ... and Mommy for that matter? Given a first-generation group of gummy bear offspring, young scientists must determine which bears are their parents. An activity worksheet covers the differences in genotypes and...

Capillary action is the frugal chemist's dream ... the less liquid used, the more tests they can run! Learners experiment with the best design to maximize the benefits of capillary action. Using a liquid sample, they design a capillary...

Model the earth's core with a neat activity that uses science as an inquiry and step-by-step procedures. The activity acquires a lot of assistance from the teacher or volunteer helpers. 

Just because we can't see it doesn't mean it isn't there! A growing concern for environmental scientists is toxic nanoparticles in our air and water. Young scholars conduct an experiment to demonstrate how these particles can cross our...

How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...
