Students complete an experiment in which they demonstrate that air exerts a force. In groups, they create their own siphon and define air pressure. They estimate the time it might take to siphon various amounts of water. They collect,...

Learners interpret and analyze data.  In this middle school mathematics lesson, students conduct an experiment in which they investigate which solar collector, black, white, or silver, absorbs the most heat.  Learners examine...

For this science worksheet, students examine the physical changes associated with the change of temperature and mixtures. The answers are included.

In this remainder worksheet, students use number sentences to solve a set of 6 problems that use 2 number sentences given at the top of the page. Answers on page 2.

In this fractions worksheet, students complete word problems about splitting different amounts of treasures. Students complete 5 problems.

in this fractions quiz worksheet, students add or subtract, solving for n in a set of equations. Answers are included on page 2. A reference web site is given for additional activities.

Students apply their knowledge of technology to help them build. In this science and technology lesson plan, students build straw towers and investigate the strength and form of the structure. They analyze the best design the make the...

Learners identify different parts and properties of circles. In this geometry lesson, students identify the radius, diameter, semicircle and inscribed angle of a circle. They identify the tangent lines to a circle.

Fifth graders draw a plan that they think will clean the sludge in a jar. Students construct the treatment system they designed, take a bottle of sludge to the system and try it out, writing down what happened.

Learners explain the laws of volume and pressure, identify what a limiting reagent is and why it is important in a chemical reaction, and distinguish between fossil fuels and renewable energy sources.

Students rotate through various hands-on experiment stations to explore the concept and properties of different types of matter. They compare some properties of solids, liquids and gases and describe how matter changes from one state to...

Students conduct an experiment called "What's the Solution? Acid, Base or Neutral." to determine the differences between these types of substance.

Students make their own pH indicator from red cabbage. Red cabbage contains a chemical that turns from its natural deep purple color to red in acids and blue in bases. Students boil the cabbage to get the pH indicator.

Pupils observe the pH change of an acid mixture poured over soil in a filter. Since the buffering capability of soils differs, you may want to do this experiment with several different soil types.

Students observe the effects of limestone on the acidity of water. Some areas of the nation have a lot of limestone in lake bottoms and in soil, which helps neutralize the effects of acid rain. Students see this effect first hand.

Learners perform an experiment that demonstrates acid rain. The chemical effect of acids on metals may take at least five days for the human eye to see, even though the reaction starts as soon as the acid contacts the metal.

Young scholars create an anemometer, an instrument that measures wind speed.

Young scholars read about a cholera outbreak in the 1840's. They read maps, predict how cholera moved throughout the country and participate in a lab activity that demonstrates how disease is spread. They compare cholera through time.

Students view the excerpt from NickNews entitled, "Winners and Losers." In groups, they categorize a variety of words and images relating to weight, healthy eating, and healthy lifestyle. They discuss adopting positive eating habits,...

Fifth graders investigate the process of water treatment. They listen to the book, "The Magic School Bus Visits the Waterworks," design a plan for a water treatment system, construct a water filter using various materials, and test the...

Students brainstorm what a fish looks like determining the parts from schema and research. They create a unique and interesting 3-d sculpture of fish or underwater creature mostly from recycled materials, then examine the aesthetics of...

Students determine the energy content of various snack foods. They measure the temperature changes in various snack foods as the foods are burned in order to determine the foods' energy content. Students create graphs and data tables of...

Students convert Celsius to Kelvin temperature. Students conduct three lab experiments, gas law simulations using Internet applets, lectures and demonstrations. The Laws included are Boyle's, Charles, Combined Gas, Ideal Gas, and Gram's...

Students conduct a pH probe of various household products including both bases and acids. In groups, they use litmus paper to test such liquids as amonia, vinegar, and detergent to discover which are acids and which are bases. Finally,...
