Students observe that colored markers are a mixture of many different colors by performing a chromatography experiment. They make observations, record information, and make generalized inferences from their observations.

Eighth graders determine the presence of starch and sugar in unknown solutions. This task assesses students' abilities to observe, record and interpret data, classify, generalize/infer, construct data tables, and identify sugar and...

Students measure the rate of sinking of a test tube into a beaker of "glop", representing a model of the interaction between the Earth's crust and upper mantle. This task assesses students' abilities to make simple observations,...

Students determine which of several soil samples (sand, soil, and slit) produces puddles, providing insight into the permeability of these different soils. This task assesses students' abilities to make simple observations, collect,...

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.

Eighth graders investigate the acoustic properties of materials in order to develop soundproofing products.  In this soundproofing lesson students research different resources, design and perform experiments and fabricate, test and...

Fifth graders discuss sustainable forestry. In this forestry lesson, 5th graders discuss how healthy forests need to have dead, diseased and lower quality trees cut down and harvested. They visit a local forest and identify these 3 types...

Sixth graders, in groups, learn the morphology and function of organelles within plant and animal cells.

Learners 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 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 measure the effect of water temperature on the rate of a chemical reaction, similar to the interaction of a weak acid and carbonate rock, using hot water and effervescent antacid tablets.

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.

Students measure the mass, volume, length and area of various objects. They are assigned a letter. The task is assesses students' abilities to make simple observations and measurements.

Students 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.

Learners design and contrast a boat made out of aluminum foil. They test the boats to see which boat floats the best using three different solutions and steel ball weights. Students work on their own to construct a boat of their own...

Ninth graders measure the insulation properties of different fabrics by immersing cans of water covered with fabric "socks" in an ice bath and measuring temperature changes. They then calculate heat loss and graph the data individually.

Eighth graders investigate Newton's Laws of Motion. They use the example of a roller coaster for illustration purposes. A force associated with a roller coaster is tested, data graphed, and a conclusion is drawn. They use excel in order...

Student's measure sporadic meteor activity.  In this physics and astronomy lesson, 11th graders construct a dipole antennae, and build, test and wire a full wave diode rectifier between the dipole antenna and the laptop. 

Learners identify and explain the relationships within a food web. They use index cards to glue pictures of producers and consumers. On the back of the card, students name the organism, list the type of biome in which it is found.

High schoolers are introduced to the structure of an atom and Dalton's atomic theory through a short video and mini-lecture. They also take a look at the weight of mass and become familiar with the idea of quantum theory

Young scholars discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample...

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.

Learners observ the cooling and warming of room temperature, hot, and ice cold cans of water by measuring the change in temperature over time. They then attempt to develop explanations for the observations made and apply their findings...

Students study and analyze data collected on the relationship between the snowshoe hare and lynx in Canada over a 28 year period and create a graph. Students also write a response to a proposal to reduce the lynx population.
