Students investigate bio-fuel. In this investigative lesson, students create bio-fuel from vegetable oil waste. Students will analyze, predict, collect and synthesize data from their experiments with bio-fuel.

Students determine crude oil can be separated into useful fractions by a process of fractional distillation. They write a balanced equation for the reaction between a hydrocarbon and oxygen.

In this sources of weathering worksheet, students read about the various things that cause weathering including plants and animals. They answer four critical thinking questions about weathering.

In this leaf chromatography worksheet, students separate the pigments of a leaf using paper chromatography. They answer 4 questions about their results and draw the colors they observe on their chromatogram from the leaf.

Students understand how clouds are formed. In this cloud lesson, students participate in three experiments to make clouds. Students complete activity sheets for each experiment.

Students examine a crushed rock and sort the minerals they find in that rock by color and other properties.

Sixth graders evaluate the nutrition of various foods. In this healthy eating lesson, 6th graders discuss the processing of many common foods and what this means. Students identify and research unfamiliar ingredients in processed foods...

Third graders learn how to use solar power.  For this sun, technology and energy lesson, 3rd graders learn how the solar power from the sun can give off energy, learn about solar panels, discuss their uses and benefits, and design a...

High schoolers examine how hazardous wastes are cleaned up. They work together to identify the positives and negatives of cleaning up certain hazardous wastes. They answer questions as part of the activity.

For this chemistry worksheet, students are introduced to the periodic table of elements. They find the answers to 13 questions about the periodic table.

Learners investigate the differentiation of magma to form different minerals present in a rock. By using the model proposed by Bowen, they determine the depth, temperature, and composition of magma. Students explain why some minerals...

Ninth graders explain the purpose of MPA's. In this biology lesson, 9th graders identify MPA's in Southern California. They simulate coastal sampling using candy from two buckets. Students analyze their results and share it with the class.

Students are introduced to the properties of solids, liquids and gases. They see that colloids are mixtures which display the properties of more than one of these states. They engage in an excellent experiment which demonstrates this fact.

In this endothermic and exothermic reactions worksheet, students experiment with water and a salt of choice to determine if heat is absorbed or released in the reaction. Students take the temperature of their solution over a 2 minute...

In this classification of matter learning exercise, students answer 15 questions about solids, liquids and gases, types of mixtures and compounds vs. elements. They also answer 2 questions about measurement and 1 question about a biome.

In this matter worksheet, students watch a movie and then compare the differences between compounds and mixtures. This worksheet has 16 fill in the blank questions.

Students write the electron configuration of elements using the Aufbau principle. In this chemistry instructional activity, students build their own key that demonstrates the principle.

Students study about chromatography, a process used to separate mixtures. They see that chromatography is used to detect, separate or purify different substances. This nice instructional activity results in a beautiful t-shirt for each...

Students compare the energy value of traditional foods eaten by indigenous people with those of modern commercial foods. They use a calorimeter to measure and calculate the amount of stored energy in various food types, and identify the...

In this periodic table worksheet, learners will label the atomic number, atomic mass, element name, and element symbol for oxygen. Then students will determine the characteristics of the different groups of elements on the periodic table...

In this Dalton worksheet, students read about John Dalton and his contributions to understanding the atom. Students are given sample data for Dalton's experiments and they answer questions about the data in his experiments.

In this atom worksheet, students read about the history of the discovery of the atom. Students write a story, poem, song or other creative project in which they shrink to an incredibly small size and are trapped in a carbon atom.

In this rock cycle worksheet, students use different colored crayons to represent different types of rocks. They follow step by step procedures to model the rock cycle with the crayons. Students draw the rock cycle, show weathering,...

Students build metal atomic models using styrofoam. In this chemistry lesson, students identify the different unique properties of metals. They explain how metal atoms bond.
