Fourth graders describe the difference between minerals (composed of the same substance throughout) and rocks (composed of two or more minerals). They recognize that there are three classes of rocks: igneous, sedimentary, and metamorphic

Learners explore the different phases of a crystal.  For this mineral lesson students grow their own sugar crystals using a sugar recipe. 

For this minerals worksheet, learners read about the relationship between elements, rocks and minerals. They experiment using 6 different colored gumdrops to represent 6 common elements. Students construct gumdrop and toothpick models of...

In this elements activity, learners review the characteristics of elements and the periodic table. This activity has 2 different versions, one with 20 multiple choice questions and answers and the other has 17 multiple choice questions...

Students explore chemical solutions. In this chemistry lesson, students investigate the relationship between three related experiments about solutions. Students determine variables that affect the chemical concentration of each solution.

Young scholars work together to test water samples for pollutants. They design data tables to collect and record their observations. They complete discussion questions to end the lesson plan.

Students experiment with silly putty.  In this chemical changes instructional activity students work in groups, perform tests and collect data.

Students examine the greenhouse gases affecting the atmosphere. In groups, they participate in activities in which they examine the effects of heat on the atmosphere and phytoplankton. They research how the phytoplankton differ in warm...

Sixth graders explore the destructive deforestation of rain forests in Brazil to clear the land for crops and livestock. Students demonstrate how the burning of a forest releases carbon dioxide by performing an experiment.

Students gain a perspective in the development of chemistry. They understand some of the topics in their text and the ongoing nature of research. They then will be able to see the trends of the periodic table first hand through their own...

Litmus paper, why so blue? A chemistry lesson includes a pre-lab activity, practice calculating pH, an experiment measuring the pH in acids and bases, a titration demonstration, and a titration experiment. 

Students investigate various chemical reactions when creating mixtures in ziplock baggies. For this chemistry lesson, students will recognize various chemical reactions and cite evidence. Safety and assessment strategies are included in...

Students explore ocean ecosystems. In this cross curriculum art and oceans lesson, students create a collage featuring three-finger algae using sand paper, tissue paper, and construction paper.

Fifth graders watch a demonstration in which a balloon is inflated using the gas created by combining vinegar and baking soda. Then, in groups, they combine various assigned substances and watch and record the results.

Test your class with a physical science quiz. Learners explain chemical processes, name compounds, write formulas for chemical compounds, balance equations, and more.
