Crystal comes from a Greek word meaning ice. Activity eight in a series of 36 has class members analyzing amorphous and crystalline solids and further classifying them based on their forces. They then explore solids, learning about unit...

Students 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 predict when an object will float or sink based on comparison of density of the object to the density of the substance in which it is placed. The access a website and sketch the object in the first column of their table and then...

In this chemistry review worksheet, students identify chemical changes, isotopes, ions, and chemical bonds. This worksheet has 32 multiple choice questions.

Lost an electron? You should keep an ion them. Young chemists learn qualitative analysis in the second instructional activity of an 11-part chemistry series. After observing reactions of simple salts, the teacher provides pupils...

The radical reactions of polymers seems abstract to many pupils, but this instructional activity turns them into a fun building game. Scholars use dice and building pieces to build polymers. Then, they determine the theoretical and...

Students test water to determine the dissolved oxygen content while displaying the proper use of testing instruments while visiting water testing sites. They determine if the amount of dissolved oxygen is appropriate for the tested...

Teach the basics of mass spectrometry with a hands-on lesson. The fourth in a series of six lessons explores how mass spectrometry measures the ionic composition of an element. Learners then compare and contrast relative abundance and...

Wow! Colorful and simple, these 160 slides introduce the various forms of energy, along with a relevant image. Some of the images are animations, which help beginning physical scientists to visualize the flow of electrons or energy! This...

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.

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

In this resources learning exercise, students compare and contrast physical and chemical properties and changes. Students review the periodic table, pattern of atomic numbers and chemical reactivity. This learning exercise has 56 short...

First graders gain knowledge about solids, liquids and gases by taking a look at the things around them. They have to classify certain picture cards based on which category they feel the picture falls under. As a whole, the class...

Young scholars engage in a lesson that is concerned with the concept of water chemistry. They conduct research using a variety of resources. Students also consider an experiment to observe how water has the abiility to exist as three...

High schoolers create a synthetic dye and oxidize the dye and record the effects.

Pupils brainstorm what matter is and how they define it. They construct a water molecule with marshmallows and toothpicks. In addition, they watch videos to explore the use the idea of nanoscience to investigate the properties of...

Students explore the properties of water and how it changes states. In this kindergarten to 2nd grade science lesson, students pair a hands-on science activity with two suggested books. This inquiry lesson has...

Young scholars explore naturally magnetic elements. In this magnets lesson plan, students examine the periodic table of elements. Young scholars discover the parts of an atom and determine which three elements are magnetic.

In this online interactive history learning exercise, students respond to 9 short answer and essay questions about the achievements of Niels Bohr. Students may check some of their answers on the interactive learning exercise.

Learners design and conduct an experiment to investigate what happens when salt and ice come together and to determine if one form of salt is better for melting ice on steps and sidewalks.

Learners test factors that may affect the rate at which sugar dissolve in water. They conduct two studies: One is to test the effect of temperature on the rate of solvation and the other is to test a factor which Students come up with...
