Learners 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.

Learners determine how to find North using a watch and their shadow. In this finding North lesson, students go outside on a sunny day and work with their shadow and a wrist watch to find out which direction that North is. They examine...

Students use the Internet to gather information on tides and then use this information to determine the period of revolution of the moon around the earth (part 1) and the relative pull of the sun and the moon on the tides (part 2).

Pupils construct a thermograph for maximum and minimum temperatures for the 2-week period. They illustrate how the earth's atmosphere is heated by convection and conduction currents and evaporation of water.

Seventh-graders solve 20 various types of problems related to ratio and rate. They write ratios in simplest form for each given statement, to compare the area of two figures, and write two ratios equivalent to each ratio. Pupils express...

Students engage in a lesson which shows them that celestial navigation is the art and science of finding one's geographic position by means of astronomical observations, particularly by measuring altitudes of celestial objects - sun,...

Young scholars recognize the importance of plants as they perform an experiment involving photosynthesis. Students determine the optimum wavelength of light for photosynthesis by exposing plants to different colors of light, collecting...

Students build a solar oven. In this Science lesson, students construct a functional solar oven. Students design the oven and explain the energy concepts involved.

Make sure your house is warm in the winter. Pupils analyze graphs of heating costs for two similar houses and make hypotheses for why the costs differ. They then build models of houses with appropriate insulation to reduce heating costs.

Young scholars explore the transit of Venus and the information that this minieclipse provides about the distance between the Earth and the sun. They create their own astronomical units.

Use a variety of whole fruits to represent the different planets in the solar system to introduce scale sizes to your math or space science class. They follow suit by creating a non-scaled model of the solar system using specific-colored...

Students observe how math is important in navigation and engineering. They study how surveyors use math and science to calcute, count, measure, label, and indicate distances on a map. They estimate specific distances.

Students describe stellar objects using terms such as stars, planets, satellites, orbits and light. In this sun and stars unit, students research stellar objects through seven individual lessons discovering star characteristics, how...

Students work together to identify the accuracy of sundials. They track the position of the sun and create a shadow plot. They discover the difference between real time and clock time.

Students compare things that are greater than, less than, or equal to, compare the Earth to other planets, and list planets from greatest size to smallest size.

Middle-schoolers solve linear equations with one single variable. They solve equations that are randomly generated using index cards. Half of an equation is written on each card and distributed to the class. which then attempts solve...

Students explore global warming by conducting a weather experiment. In this greenhouse gas instructional activity, students define the greenhouse effect and the impact on our ozone layer. Students utilize a soda pop bottle, floodlight...

Students determine the relative size and distance of the planets in the solar system. They use ratios in their mathematical calculations to make models of the planets after discussing the relative sizes of the planets. They keep a...

Students explore the concept of daylight. In this daylight instructional activity, students compare the amount of daylight on a particular day in Anchorage compared with daylight where they live. Students color maps of the US according...

Students explore physics by conducting a class experiment. In this gravitational force instructional activity, students define several scientific terms associated with force. Students utilize a styrofoam cup and marbles to simulate a...

Learners research the characteristics of planets in our solar system. In this space science instructional activity, students create a solar system model with each planet arranged according to their distance from the sun. They solve...

Students discover scales for both the solar bodies' relative sizes and their distances from the sun. They find equatorial circumference and volumes of their solar bodies. Students apply estimation strategies and proportioanl reasoning to...

Students study the reason why time zones exist and how they are established. They predict time zones for different places on Earth.

Students investigate reaction rates.  In this seventh or eighth grade mathematics lesson, students collect, record, and analyze data regarding how the temperature of water affects the dissolving time of a sugar cube. Studetns...
