What makes particles attract? Here, learners engage in multiple activities that fully describe colligative properties and allow the ability to critically assess the importance of these properties in daily life. Young chemists...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

In this chemistry worksheet, students examine a concept in science and then use the knowledge in application by conducting an experiment.

For this gas laws worksheets, learners figure volumes, densities, molar masses, reactions, and solve equations as they encounter 14 gas laws questions.

Topping this worksheet is a comprehensive collection of notes about phase changes. The phase change graph is displayed, along with formulas for the gas laws, and information relating energy to change of phase. After reviewing these...

In this equilibrium worksheet, students answer 5 questions about reactions reaching equilibrium, the concentration of the products and reactants when they reach equilibrium, and the effects of temperature changes, quantities of reactants...

For this biology worksheet, students examine the process of respiration and specifically look at the biochemistry of gas exchange at the alveoli.

In this biology instructional activity, high schoolers examine the transport of gases in the circulatory system and how they bond to hemoglobin.

Students examine the similarities and differences between weathering and erosion. They participate in a lab in which they test the effects of different materials when exposed to weathering and erosion. They record their observations.

In this chemical reaction worksheet, students apply Le Chatelier's Principle to explain how the given changes in reaction conditions will affect the position of equilibrium. This worksheet has 6 problems to solve.

In this equilibrium instructional activity, students predict the concentrations of solutions at equilibrium and apply Le Chatelier's principle to systems at equilibrium. This instructional activity has 15 multiple choice questions.

In this chemical equilibria worksheet, students write equilibrium expressions for chemical reactions and calculate the value of the equilibrium constant. This worksheet has 8 problems to solve.

For this chemical reactions worksheet, students calculate the equilibrium constant for given reactions. Students decide if reactions are homogeneous or heterogeneous and if the equilibrium favors reactants or products. This worksheet has...

Students use simple materials to make model sailboats which must stay upright and sail straight in a testing tank.

Written for an exploration of shoreline ecosystems on Sheffield Island, this gives ecology or marine biology buffs a hands-on experience. Using GPS or visual triangulation techniques, they lay transect lines on a high and a low energy...

For this earth's layers worksheet, students learn about the 3 different layers of the earth: core, mantle and crust. They then use this information to answer the 16 questions in the packet. The answers are all on the last page.

Students present information about a species, its niche, and adaptations. In this lesson on animal environments, students explore how surroundings can affect a given population resulting in adaptation.

Pupils study the geologic history of terrain, soils, and drainage patterns. They recognize ecological processes that determine the dynamic nature of habitats. They investigate the influence of human activity on the landscape.

Learners construct a block model of the Space Station. They develop a description of their procedures, complete flow diagrams of their processes, develop a budget, and present their block model to the class.

Learners study plate tectonics.  In this plate tectonics instructional activity students build a cutaway scale model of the Earth. 

Students replicate a volcanic eruption. In this volcanoes lesson plan, students follow the provided procedures to show and describe how the inflation of a bulge led to the eruption of Mount St. Helens.

In this science worksheet, students look for the words that are related to the theme of the sheet in the word search. They also work on spelling skills.

Pupils write their own newspaper article about a weather story using newspapers and a weather records worksheet.

Students write newspaper articles using a "weather record" worksheet and information they find in newspapers.
