Students measure the properties of two different types of soap and wood and calculate their densities. Then they predict whether or not whether or not each object would float or sink in fresh or salt water.

Students must design and conduct an experiment to determine which unknown liquid has a greater density based on basic information about the liquids and containers. Students are given specific materials to work with.

Students determine the mass, volume, and density of two different mineral samples. Students show data and calculations as well as answer questions about the mineral identities.

Students collect data on the cooling of water in two different test tubes, one that is wrapped in wet newspaper and one in dry newspaper. They then relate this cooling effect to the body's perspiration.

Learners design and conduct an experiment on unknown solutions after studying descriptions of indicators and the way in which they identify acids and bases. Students must gather, organize, and analyze data as well as make inferences...

High schoolers conduct simple sampling of plant and insect biodiversity at ground level in two contrasting environments of their own choosing. They recognize and record different species then compare and contrast species numbers in the...

Students determine the most appropriate site for a car wash, based on each site's soil characteristics (chemical, physical) and topographic features. They perform an experiment to determine the changes to three different soil types when...

Students perform a simulation in which they work for a toy company and have to figure out how many marbles of different sizes can be made with the provided material. They must design their own experiment to figure this out.

Fifth graders hypothesize and design an experiment to study the relationship between a block weight and the number of washers it takes to pull a block across various surfaces. Students graph results and apply their findings to a...

Students discover enzyme to substrate specificity. The experiment uses samples of glucose and lactose in combination with the enzyme lactase. Students observe the reaction between the lactose and the lactase; the lack of a reaction...

Students observe the motion of both a pendulum and a spring pendulum . They then explain the differences and the similarities between the two types of motions.

Students examine the properties of a liquid that contains water and food coloring and a liquid that contains water, food coloring and a liquid detergent. They interpret their data, describe properties, and make reasonable explanations...

Eighth graders observe two types of interactions in a sealed plastic bag. One bag contains baking soda and water, and the other baking soda and vinegar. They determine what evidence indicates that a chemical change is occurring.

High schoolers circulate through stations to determine the proper instrument to make a certain type of measurement. They must make measurements of mass, volume, length, area, electrical current, temperature and force.

Students role several balls of different weights down a ramp and into a paper cup and record how far each ball made the paper cup move. They then answer questions that help them analyze their results and reinforce the idea that energy...

Students catagorize the types of garbage from going through a trash can provided by their teacher. They then chart the items on a graph and propose a solution to reduce the amount of garbage.

Students determine the average speed of a toy car as it travels six different distances set up by Students. Three trials are done for each distance. The only requirements is that the longest distance must be at least three times longer...

Sixth graders are instructed on how to create a pendulum and measure the periodicity of the pendulum, using four different combinations of string. They are asked which influences the time more- the length of the string or the weight at...

High schoolers design and carry out an exercise to determine if a given fruit or vegetable is composed of cells. They dissect out sections of the fruit or vegetable, prepare stained slides, and make observations under a compound microscope.

Students examine tadpoles at various stages of development. They make careful scientific observations and compare the changes that occur at five different phases of a frog's life.

Eighth graders determine the location of specific features of the stimulated ocean floor. The features include the continental shelf, continental slope, an ocean trench, and a mid-oceaniz ridge.

Fourth graders rank balls by size from smallest to largest and from lightest to heaviest and then by how much they made the water rise. They then discuss why certain balls make the water rise higher than do other balls.

Young scholars examine the effects of heating on various crystals. They answer questions in the observation category which assess their ability to use a variety of senses to observe data in a certain way- a scientific way.

Students examine the effects of heating on various crystals. They formulate and revise scientific explanations and models using logic and evidence. Students work individually during this experiment.
