Middle schoolers explore heat energy and how it is used to change the phase of matter, and discover that temperature does not increase or decrease until the phase change is complete. This extremely well-written plan is packed with great...

Dare your class to drive dissolved carbon dioxide out of carbonated liquid at different temperatures to discover if there is a difference in rate. To make this experiment more sound, have explorers use equally measured amounts of soda...

Investigators use indirect evidence to guess what is occupying a sealed box. You could also use a set of plastic Easter eggs to encase the unknown items. Another terrific activity involves having high schoolers drop a pencil on a sheet...

In this teacher-led demonstration, your young environmentalists will observe and record how different types of water pollutants look when they are combined. From here, individuals will develop a hypothesis on how the water can be...

Looking for a terrific chemistry lesson for your 5th graders? This one could be for you! After a teacher-led demonstration, learners are broken up into groups and perform an experiment using cabbage juice, water, window cleaner, and...

Four activities immerse beginning chemists into the world of elements. They examine the periodic table, use cobalt hydroxide to learn about chemical formulae and valence electrons. Also, they name binary compounds and examine the...

Create models of the infrared, visible, and ultraviolet portions of the electromagnetic spectrum. Working in small groups, your class can investigate metric conversions calculations. They will find the length of the waves in nanometers,...

Junior geologists work through three mini-lessons that familiarize them with the formation and location of fossil fuels. Part one involves reading about petroleum and where it comes from via a thorough set of handouts. A lab activity...

Learners investigate chemical reactions involved in making a blueprint. In this blueprint paper lesson plan, students expose blueprint paper with writing that has been soaked in a solution of potassium ferricyanide and iron (III)...

Make sure to consult the teacher's handbook, Inquiry in Action - Investigating Matter Through Inquiry, for two demonstrations that can be done to introduce solubility and measuring crystal mass before having the class conduct this...

Three simple activities kick off a unit investigation of density. Your physical scientists make observations on the volume and mass of wood, water, and rocks, and make comparisons. Though this is written for grades three through eight,...

Learners differentiate between current and static electricity, conductors and insulators, explain how energy is converted from chemical to electrical, measure voltage of batteries, collect data on voltage, and predict voltage of...

Chemistry aces use an electrochemical cell to anodize a strip of aluminum. They apply an organic dye to it. In a practical application, they design a piece of jewelry out of the anodized metal and describe the process. Thorough notes...

Advanced chemistry kids experiment with the freezing and boiling points of various aqueous solutions. They also prepare a presentation of the kinetics of solution formation and structure of the matter involved. This resource provides...

How did scientists determine the cause of illness before technology? Science scholars play the role of medical researcher in an engaging guided inquiry activity. Using observations, technical reading, and Punnett squares, learners...

Teacher's notes, a materials list, detailed procedure, tips, and extension ideas are all included to make teaching this lesson on photovoltaic cells a sunny spot in your day! After some brief background reading, physical science...

Experienced chemistry technicians use then layer chromatography to discover how much of a free compound is left after each rinse cycle. Where this could obviously be used as a practice with chromatography technique, it can also be used...

Young scientists investigate the water cycle through a lettuce seed experiment. For this experiment, learners plant lettuce seeds inside of a ziplock bag in order to create a small greenhouse. They observe condensation and precipitation,...

Processed foods use inorganic compounds for flavoring and preservation. This take-home laboratory challenges scholars to find 20 different compounds identified on the labels of foods to list on their data collection sheet. The activity...

In this science worksheet, learners collaborate as a group of 4 to conduct a science investigation about the water cycle. Students read about the specific job responsibilities for each team member and record their findings on this sheet.

As part of a unit investigating the dissolving of M&Ms® candy coating, this lesson examines whether or not the different colors combine. There are no new concepts revealed in this particular lesson, but learners will see that the...

Students investigate the concept of a job and how they can differ for each household. They examine a tool box filled with different tools and identify the types of jobs could be done with them. Then the teacher conducts a class discussion.

Winter, spring, summer, and fall—take the learning of the seasons beyond the elementary level to the middle school classroom. Curious learners begin by watching videos about the seasons and the rotation of planet Earth. Then,...

How can you tell if something is made of metal? Use a table of data and a science experiment to determine which items are made of metal. The experiment requires adult supervision, as it instructs third graders to build an electrical...
