The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

All of the gas giant's atmospheres consist of hydrogen and helium, the same gases that make up all stars. The third in a series of 22, the activity challenges pupils to make scale models of the interiors of planets in order to...

Huygens spacecraft landed on Saturn's moon Titan in 2005, making it the farthest landing from Earth ever made by a spacecraft. In this hands-on activity, the 12th installment of 22, groups explore how density affects speed. To do this,...

Explore and brainstorm innovations for cars with a STEM lesson that asks scholars to weigh different options when considering when buying a car. They research the fuel efficiency and carbon emissions for various options, and then...

All soil is not created equal! A lab activity asks learners to collect and analyze soil. Specific calculations determine the amount of sand, silt, and clay in a sample and allow individuals to identify the soil texture. 

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

Sometimes, despite the best laid plans, the unexpected will occur. Learners witness this firsthand as they carefully design an experiment to determine the time needed for ice to melt in salt water or pure water. They uncover facts not...

Students define, give similarites and differences between solids, liquids, and gases. They compare and contrast a solid, liquid and gas in terms of shape, volume, compressibility, diffusion and density. Pupils classigy common...

Youngsters sort M & M's by color. They graph the M&M's by color on a graph. This classic lesson is a wonderful way to introduce the concept and technique of graphing to young mathematicians. Pairs of kids can make up their own...

Young scholars record information from the periodic table for sodium and chloride. They determine whether salts are molecular or ionic compounds, along with sodium chloride's molecular weight, and relative weights

Learners examine concept of time, and explore difference between analog and digital clocks; students make art project to represent time and create a time-story problem and solution.

Learners examine the legitimacy of advertisers' claims about products using science and critical thinking. They view and discuss ads, read a case study, and conduct an experiment to demonstrate whether a product lives up to its claims.

Young scientists discover how many, many animals use color as a way of helping them to survive in the wild. They understand how animals use color in their everyday lives. Pupils engage in hands-on activities, watch videos, access...

Complete a unit of lessons on hearing and sound. Learners conduct sound experiments, research the history of the telephone and scientific contributions of Alexander Graham Bell, and create a model of the human ear.

Students examine problem solving techniques when working on spatial problems. They discover how models, sketches, and drawings can be used to understand on something works. They design a model of a bridge using given dimensions and...

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

Third graders investigate two mathematic scenarios and determine which is correct. They compare adding columns and places (such as the tens place, hundreds place, and so on) and familiarize themselves with how to add larger numbers.

Explore ethanol and how it is produced. Young scientists investigate photosynthesis and fermentation to the concept of conservation of energy and mass. They discuss the environmental and economical benefits of ethanol as a fuel additive.

High schoolers explore displacement. In this displacement and density lesson plan, pupils find the volume of irregular shaped objects. Afterward, they determine the volume of containers. They compute the amount of water displacement.

I would weigh less on the moon? Send me there, then! On the top of the first page, a cartoon image demonstrates the difference between Earth and the moon. It then goes on to describe weight and mass and provides five practice problems...

Have your class engage in lessons on earthquakes. Learners explore the science behind earthquakes using interactive websites and video clips. Then, they review the layers and parts of the Earth before delving into the causes of...

More extensive than just a general overview of digestion and reactions, this slide show gives information about all areas of enzyme function.  Topics like the chemistry behind efficiency of enzymes, factors that affect speed of...

Challenge your sixth graders with this lesson about the freezing and boiling points of water. In these activities learners graph temperature data, read and analyze information, and identify the freezing and boiling points of water and...

After listening to a story about the water cycle, learners create their own versions of this tale. This is a great way to have your class review the concepts of evaporation, condensation, precipitation, and runoff.
