Students examine stoichiometry. In this chemical reaction and mole lesson, students complete an experiment based on readiness levels to explore that changes are quantified in chemical reactions.

Youngsters test magnetic strength by measuring the mass of paper clips that they "hook" with a magnet. Your first and second graders should love the hands-on activities associated with this plan. The reproducible materials are quite good...

Students study a way to quantify the process of photosynthesis during a given time using the Elodea plant. They design a hypothesis that they test in the hands on activity. They compare the amounts of photosynthesis that occur during low...

Students enact the life cycle of a sessile animal and quantify the possibility of survival under the conditions given. They then present to the class a new adaptation which will increase the animals chance of survival.

Learners design an investigation using yeast. In this environmental engineering lesson, students design an investigation to determine how environmental factors affect the growth of yeast. They will collect quantitative data and discuss...

Students study the scientific evidence about carbon dioxide emissions. They learn to calculate the amount of energy used by different appliances. They complete a worksheet which analyzes the amount of energy that their home uses.

Students construct a rocket from a balloon propelled along a guide string. They use this model to learn about Newton's three laws of motion, examining the effect of different forces on the motion of the rocket. They measure the distance...

Desert regions are hotter for multiple reasons; the lack of vegetation causes the sun's heat to go straight into the surface and the lack of moisture means none of the heat is being transferred into evaporation. This concept, and other...

Pupils often wonder how we know the distance to various stars. Starting with a thought experiment and progressing to a physical experiment, they determine the brightness and distance to various stars. The evaluation requires...

Dust is everywhere around us; it's unavoidable. But what exactly is dust and are certain locations dustier than others? These are the questions students try to answer in an interesting scientific investigation. Working independently or...

Raise children's awareness about the importance of conservation with this hands-on science lesson. Start by breaking the class into groups and having them collect trash from around the school or local park. Students then use the provided...

In this asteroid and comet activity, students read about the formula used to determine the brightness of asteroid. They apply this formula to solve 2 problems about asteroids and their brightness.

In this energy in empty space worksheet, students use an equation for Cosmic Inflation to solve eight problems. They find the domain and range of the function of the equation, they determinethe axis of symmetry, they find the critical...

Students discuss biological diversity in ocean communities. In this diversity lesson plan, students examine the variety of organisms compared to relative abundance. They will write an analysis and discuss their findings with the class.

Students create model coral reefs showing surface area and including examples of communities.  In this coral reef lesson plan, students research and explore the functions or benefits from a coral reef.  Students design a...

Learners calculate the board footage of a tree. In this forestry lesson, students use a Biltmore tree scale stick to calculate the number of board feet that would be produced. They quantify the economic value of a tree from this...

Weathering is not necessarily a result of the weather. Scholars conduct an experiment to explore the effect of surface area and volume on the weathering process. They create their own sugar cube rocks using the same number of cubes—but...

Students explore the concepts of mean and variance. They observe properties of materials to their basic atomic or molecular structure. Students use spreadsheet software to record, tabulate and analyze collected information.

Students produce a vertical profile of a stream and map and define thalweg, point bar, and cut bank. They measure flow velocity differences across a stream transect and equate flow velocity with size of substrate sediment collected.

Students determine the amount of vitamin C present in 3 samples of juice stored in various light conditions. In this vitamin lesson plan, students investigate the amount of vitamin C present in juice exposed to different quantities of...

Students read and discuss waves and their wavelengths and amplitudes. In this waves lesson plan, students draw the wavelength and amplitude of a wave and discuss tsunamis and storms.

Learners explore disease and its relationship to history and literature. They investigate issues that range from early biological warfare and historical disease treatments, to observing today's race for the cure against current emerging...

Students examine Newton's three laws of motion to discover what causes it and how it changes. They conduct motion experiments by building catapults and constructing balloon rockets. Finally, they conduct peer studies correlating...

Students explore various tree species. In this tree species lesson, students collect leaves on nature walks and use Internet sources to identify the trees that the leaves belong to. Students graph their data as well.
