First in a two-part instructional activity on the greenhouse effect, this instructional activity involves a classroom demonstration of the phenomenon, and a lab group experiment with color and absorption. Although there are easier ways...

If objects have no heat, how do they can gain and lose it? Scholars experiment with heat, temperature, and specific heat of various substances. They create definitions for these terms based on their own conclusions to complete the fourth...

Students observe a scientific discrepant event, and are then challenged to create experiments to solve the dilemma.

Rock exploration, so exciting! After reading the book Everybody Needs a Rock, the class makes sandwiches to better understand that the Earth is made in layers. They then use a description of the 3 types of rock to conduct an observation...

Young scholars describe characteristics and common uses of acids and bases. They describe the role of natural indicators in the chemistry of acids and bases after testing and making observations on a variety of plant extracts. Students...

Students conduct an experiment. In this forms of water instructional activity, students observe ice to see what changes take place and then write in their journal about what they observed.

In this chemistry of ice cream worksheet, learners investigate colligative properties and how they affect freezing points while making ice cream. Students answer short answer questions to determine if freezing is an endothermic or...

Students participate in a lab activity using three tuning forks of different frequencies and a Resonance Tube Set purchased from Sargent-Welch to take measurements of resonant lengths of the tuning fork frequencies. Students then try to...

"Self-guided Computer Activity" simply means that young chemists read through the slides and take notes about atoms along the way. There is an abundance of text on each slide, making this a comprehensive introduction to atomic structure....

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...

Students identify and use the elements of the scientific inquiry to solve problems. They explain concepts about the structure and properties of matter. Pupils write an explanation of polymers and how the characteristic of polymers...

Middle schoolers experiment with common household products to determine the properties of emulsions and how they fit into the classifications of matter through this series of lessons.

Young scholars work together to develop a container to keep an ice cube in a solid state. They identify the three stages of matter and test different materials for this experiment. They share their results with the class.

First graders compare and contrast water from different sources. After collecting water from various sources, 1st graders create a list of observable properties of the water. Students then pour the water into a filter and observe the...

Students investigate the changes that occur at the molecular level when a liquid becomes a solid. They freeze water in baby jars and observe the changes that occur in the process.

Students examine how candles work and how scientific theories are developed and tested. Students propose hypotheses about what is burning in a candle then perform tests in order to develop their scientific theory. After a teacher...

There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

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...

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

Fifth graders complete a instructional activity which has them place a list of gases in order from the least to the most dense. The density in grams is given for each. There's a good paragraph which provides background knowledge about...

Young scientists discover that air is a mixture of different gases - mainly nitrogen and oxygen. The properties of some of the other gases found in oxygen are listed in a table, then learners must decide which one of those gases is...

At some point, everyone has been under pressure—even Dalton! Explore Dalton's law of partial pressures with young chemists as they measure the volume of air extracted from a sample compared to its original volume. Class...

Messenger's sun shade measures 8 ft x 6 ft and will have temperatures reaching 700 degree Fahrenheit on the outside while maintaining a cool 70 degrees underneath. In the third activity of four, groups discuss the basic properties of...

What can one learn about a planet based on a small surface sample? Learners will explore artifacts from a mystery planet and see what they can determine about the planet based on the evidence in front of them.
