Stephen Perry invented and patented the modern rubber band in 1845. Young scientists put his discovery to work as they use rubber bands to observe entropy and enthalpy. They determine the change in free energy to figure out if it...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Floating fragments of elodea can grow even without roots. Young scientists use eldoea plants to observe the oxygen production from photosynthesis. They study the difference between having access to high amounts of light and low amounts...

You might not be able to learn through osmosis, but you sure can observe it! Scholars observe and measure osmosis using chicken eggs. They control for multiple variables to determine which variables have an impact and how the impact...

How do scientists analyze data to get a specific answer to a question? The final chapter in an eight-part series of activities centered around Gorongosa National Park encourages scholars to dig deeper into the scientific process. After...

What can this rock be? Pupils pretend to be paleontologists by sketching fossils and making predictions about their types. To determine whether they can identify the type of dinosaur, class members compare their observations and...

Investigate the water cycle and how water moves from the land to the air and back to the land. Create a terrarium and observe the water cycle at work. Define weather terms including evaporation, condensation, and precipitation.

Research the interrelationship between math and science. Search the Internet to discover the history of several branches of mathematics and make text-to-world connections between the concepts covered in each branch with related...

A nose knows! Connect animals to their noses with a fun science activity. Animals include elephants, rats, pigs, and even humans. For a science exploration, kindergartners answer questions about what they can smell. A great addition to...

Examine the properties of light with a fifth grade science experiment. Pupils find out how light bounces off the surface of a mirror, as well as how a periscope works. For the science investigation part, kids build their own periscope...

Learn how to measure weight with newtons in a science experiment about gravity. After they read a short paragraph about force, fifth graders draw an arrow to indicate which way a spring is being pulled. Next, they survey their family...

Super detailed, this activity will educate physical science learners about the flow of electrons. Begin by reviewing potential and kinetic energy with a moving pendulum, and then get them online to observe interactive websites about...

Opposites attract with a fun science experiment on magnets. With a short paragraph on background knowledge, the lab sheet prompts third and fourth graders to choose which pairs of magnets will attract, and which pairs will repel. A...

Is sugar more soluble than salt? Experiment with water and solubility with an elementary science activity. After interpreting data from a bar chart, fifth graders use different types of sugar to determine if the size of sugar particles...

Practice making shadows with a kindergarten science experiment. After deciding which picture would represent the biggest shadow, kids use a flashlight to experiment with their own shadows. For extra fun, have kids mark their shadows...

Get things cooking with the first lesson in this series on the science of food. Working in small groups, young scientists make and record observations about different mystery foods. These descriptions are then shared with the class and...

Don't let your eyes play tricks on you ... use scale to keep your eyes in check! Young scholars observe images without scale and try to identify the structure. Then, they look at the same image with a scale bar and assess whether their...

Biology beginners observe traits in a collection of plant parts to realize the tremendous amount of genetic variation within a species. They consider rules of nature and discuss what would happen if they changed. They also examine data...

An introductory exploration of the nature of light is provided via activities and demonstrations. Science superstars observe various light sources, learn how to apply inverse square law, and practice using a light meter. Follow-up...

Take your science class on a hypothetical field trip to Mars with an engaging astronomy lesson. After first learning about NASA's Mars rover missions, young scientists plan their own scientific investigations of Earth's...

Middle-schoolers still enjoy playing with bubbles! In this series of eight laboratory activities, science learners explore convex and concave surfaces, angles, gas laws, buoyancy, density and more! 

Young scholars experiment with states of matter with water and ice. In this states of matter activity, students experiment to discover what happens to water as it freezes to become a solid, ice. They observe what happens when ice melts...

A video and laboratory investigation are highlights to this activity on acidification of ocean water due to increased atmospheric carbon dioxide. Using bromothymol blue (BTB) as an indicator, pupils analyze the amount of carbon dioxide...
