Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

By rolling marbles down a six-foot length of track, physical scientists determine how much energy is lost to heat. It is recommended that you opt for the foam pipe insulation track because more friction slows the marble, allowing...

Raise children's awareness about conservation with this series of vocabulary activities. Offering riddles about endangered species and a crossword puzzle involving key terms relating to conservation, these fun worksheets will...

Explore the center of gravity with your science class as they create a deadfall trap with common materials. They research the concepts of energy conservation and gravitational force before dividing into small groups to create a model of...

Can a small change in laboratory procedures save energy? Scholars test three different methods for heating water in a science lab. Then, they calculate the energy efficiency for each and compare them to determine which uses the least...

Going green? Scholars investigate the creation of the US National Park program. Through diary entries as well as expert testimony, they synthesize information and analyze the need for conservation and preservation. Finally, they display...

How do you teach a student with visual impairments about the conservation of mass? You use tactile models that represent the theoretical concept. Baking soda and vinegar are used to add gas to a deflated balloon. Learners will feel the...

Assist your class with understanding collisions as they apply the Law of Conservation of Momentum. Pupils measure the momentum before and after manipulation of two objects so that one strikes another in an inelastic collision. The lesson...

Conserving energy is an important part of helping the environment. After coloring a picture of a hand turning off a light switch, kids copy the word onto a handwriting line.

From turning off lights when leaving a room, to biking or walking to school, there are many simple habits children can develop to help preserve the earth. Help raise environmental awareness in your class with this activity packet that...

Steam engines have been around since the late 1600s, yet most pupils don't know how they work. Using an soda can, the instructor builds a simple steam engine for scholars to observe. Through a discussion, young scientists learn about the...

What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine...

Technology or engineering teams are given a task to design, construct, and test the efficiency of a structure that will foster an even temperature throughout an entire sunny day. Intended as a long-term project, pupils research, plan,...

Here is a 20-box bingo card to use when exploring ways that humans impact the environment. Various environmentally aware activities are listed in the boxes, and learners circulate the room to find someone who practices the different...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

Roll with your class into the idea of conservation of energy. Pupils use a roller coaster track to collect data to reinforce the concept of conservation of energy and the influence of friction. Class members then create a graph from...

How high will it bounce? Groups determine the height different balls bounce off of different surfaces. By performing the necessary calculations, they determine the initial and final momentum of the balls. The included worksheet provides...

Skate through a simulation on energy with an a activity that uses a computer simulation of a skater to reinforce the concept of conservation of energy. The resource guides pupils through scenarios using the computer simulation to...

How efficient is a motor in a LEGO set? Future engineers conduct an activity where a LEGO motor-generator system raises an object to a specified height. They then show what they learned and use their measurements to calculate the energy...

Food will win the war! At least, that is what some World War I-era posters say. Using two propaganda posters—one in English and one in Yiddish—young scholars consider why the Wilson administration had the posters created. Discussion...

Youngsters compare the heat-holding abilities of three different cans by insulating two with different materials and measuring the temperature change of hot water over a 20-minute period. 

If you are looking for worksheets about alternative energy sources to use on Earth Day, you'll find several here. However, since Earth Day is all about conserving natural resources, please print these double-sided in order to reduce the...

The Maltese Cross Cabin, a frontier residence of Theodore Roosevelt, is a time capsule that commemorates Roosevelt's time in the Dakota territory. An explanatory video and response guide takes students on a virtual tour of the wooden...

Water may be everywhere but it is not always drinkable. Pupils research water issues, first in a local setting and then with Papua New Guinea and Australia to get a larger world perspective. Teams use the Internet and other...
