In this trees lesson, 4th graders read the book, A Tree is Growing and complete a KWL chart on how trees grow and how they are used. Students research the symbiotic relationship of humans and trees, create tree collages, plant a...

Humans tend to huddle together when cold and move around more when warm, but do gas particles follow the same pattern? Scholars use a temperature probe, a pressure sensor, and air to study the relationship between temperature and gas...

Do your high school scientists know the four methods scientists use to communicate information? A simple experiment discovering the relationship between gas pressure and volume allows pupils to practice all four. After completing the...

Fifth graders explore the relationship between potential energy and kinetic energy.  In this energy lesson, 5th graders examine objects and describe  potential and kinetic energy of the objects. Students complete two worksheets.

Looking for a quick way to supercharge your electricity and magnetism unit? Assign a very responsive interactive designed to illustrate the relationship between charge, electric field, and the resulting forces. Learners experiment with...

Learners investigate density and its relationship to air and gas. Students perform experiments to determine if gases have mass. They explore possible ways to figure out the density of gases.

Aspiring astronomers study stars. They compare stars and explain the relationship between radius, mass, and diameter. By creating a star simulation, they discover how a binary star system's orbit can cause changes in the observed...

Your older elementary students investigate electromagnetic energy and the electromagnetic spectrum. They will observe 7 items represented in the electromagnetic spectrum and make a poster of all the things the items have in common. After...

Two laboratory problems are put forth for chemistry high schoolers. They are to plan and carry out an experiment that will answer each of the questions. The first asks them to investigate a relationship between the surface area of a...

Test six various reagents for their ability to conduct electricity. Cooperating chemists research whether each is ionic or covalent and discover the relationship between bonding and conductivity. This laboratory exercise would be an...

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

Have you ever wanted to turn off gravity? This simulation allows learners to do just that in addition to altering other variables. Scholars can move the sun, Earth, moon, and space station to see how distance affects gravitational pull....

Students describe the relationship between exercise and health. They name ways to monitor their health and the equipment used to do so. Students name solutions to common health issues and explain why good nutrition and exercise are...

What better way for young biologists to learn about invertebrates than by creating their very own? Here, students are assigned a set of invertebrate characteristics and are asked to invent an imaginary ocean animal...

Does carbon dioxide really affect temperatures across the world? This fifth installment in a six-part series investigates the relationship between carbon dioxide and global temperatures. Graphs created from genuine data help...

How much does your class know about the relationship between climate change and carbon dioxide? Science scholars explore the nature of greenhouse gases and rising ocean temperature through demonstrations, research, and experiments. The...

Students determine that the relative concentration of copper ions in water can be determined by a color comparison. They make a copper (II) sulfate solution of a given concentration. Students dilute their initial solutions until their...

Students examine how the circumference, diameter, and the relationship of Pi of a circle are related. They count the summer rings of a tree to determine its growth.

In this radon and radioactivity worksheet, learners analyze the data of the isotopes of elements that occur in the decay series of uranium-238. Students answer 6 questions about the isotopes, their half-lives, their potential threat and...

High schoolers find the relationship between the variables based on experimental data. They determine mathematical relationship between pH and the amount of hydrogen Ions in solution.

Students apply the science of chemistry to soil and plant relationships. They define diffusion and indicate for which of these nutrient(s) would you expect diffusion to be the most important for movement to the plant root? Pupils...

Young scholars investigate the relationship of the steps in the water cycle, and create a simulation of the water cycle in a jar.

Students explore the effects of different density-dependent and density-independent factors on population growth. They explore how the interactions of organisms can affect population growth. Students explore the pattern of population...

Acids and bases have a love-hate relationship. They balance each other so nicely, but they are complete opposites! Learners use these concepts and titration to calculate the molar mass of an unknown substance. The experiment...
