Students use models to visualize molecular structures. Students read about Lewis dot structures, hybridization, and formal charge. Then students build and draw the molecules and ions given. Students complete 11 pre-lab questions and 4...

Learners investigate elements by by defining scientific terms.  In this Periodic Table of Elements lesson, students utilize a glass of water, and powdered fruit drink to perform a lab activity demonstrating properties of certain...

Students discuss potential and kinetic energy and design roller coasters to study this concept. In this energy lesson plan, students discuss the potential and kinetic energy of a roller coaster. Students design roller coasters and...

Students recognize both a physical and chemical change in different substances. They determine which particles actually changed into different substances, and explain if it represented a physical or a chemical change.

Explore the unique characteristics of polymers. A complete lesson begins with a presentation introducing polymers. Following the presentation, young scientists develop a laboratory plan for creating substances using polymers. They...

Acid-base indicators are an essential part of any chemistry classroom. Individuals explore the color-changing feature of the important indicators in a vibrant hands-on activity. Using serial dilution, learners create solutions ranging...

Looking for a quick, hands-on activity to teach young scientists about Punnett squares through monohybrid crosses? then check out this one.

What can conductivity tell us about a glacier? Groups analyze glacial melt to determine salt content through an analysis of the pH and conductivity measurements of two samples. Groups then determine the source of the salts. 

Plankton are so abundant in the ocean they outweigh all of the animals in the sea. In this three day activity, groups discuss and become familiar with plankton, capture females, and look for egg production on day three. 

Merge chemistry with environmental science to study biodegradable materials. An engaging activity allows learners to experiment with different resin concentrations and composites. Through experimental tests, scholars test their creations...

What is a reasonable percent yield in the manufacturing process? Scholars develop a process for producing chalk in the third lesson of a six-part series. Then, they must determine the theoretical and percent yield. Discussions about...

How do we clean up oil spills and other pollutants in the water? Explore water treatment strategies with a set of environmental science experiments. Groups remove oil from water, work with wastewater treatment, and perform a water...

Excite classes with a STEM project-based learning lesson covering chemical reactions. Groups study the different types through simulations and hands-on activities. They pick one type (synthesis, decomposition, single displacement, double...

Explore the importance of a concentration gradient in the rates of dissolution. Using the ocean ecosystem, learners study rates of dissolution around coral reefs. A hands-on experiment helps individuals discover the effects of changing a...

While all light travels at the same speed, each color in the visible light spectrum contains a different wavelength and frequency. Scholars determine the relationship between frequency and wavelength as they complete the activity. They...

See what you cannot see by getting a little creative. An intriguing lesson has learners use lasers to explore X-ray diffraction. Given a box with unknown structures, they shine a laser through the box and interpret the results....

How do scientists determine when a solution is fully saturated? Scholars address the topic as they observe patterns of precipitation in various concentrations of ions. Using a well plate, pipette, and common chemicals, they collect data...

Youngsters compare the heat-holding abilities of three different cans by insulating two with different materials and measuring the temperature change of hot water over a 20-minute period. 

How does carbon dioxide affect the world's oceans? The final installment in a series of six lessons has pupils research ocean acidification, then conduct an experiment to witness the delicate balance that exists in our seas. Materials...

Note that this lesson is best paired with the preceding lesson in the unit. In that lesson, elementary physical scientists observed that the color coating of M&Ms® candies do not mix when dissolved off of the chocolate surface. Now...

This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is...

Did you know some food dyes are considered safe while others are considered carcinogenic? During the experiment, young chemists extract artificial food colors from prepared foods. Then, they use chromatography paper to identify...

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...

Scholars continue their study of event-driven programming by creating a multi-screen app in the fifth lesson of the series. They incorporate previously learned elements and events in the mini-project.
