Tired of waiting for hot water? Groups of three determine the efficiency of an electric water-heating device. They calculate the amount of energy it takes to heat the water and the theoretical amount of energy required to heat the water....

In this ice and water worksheet, high schoolers read about the energy needed to transform ice to liquid water. Students solve 3 problems where they calculate the energy needed to melt ice given different scenarios in space.

Students investigate temperature using the TI. In this chemistry lesson, students analyze the change in temperature, as chemicals are dissolved in water. They analyze data collected using the CBL 2.

In this fractions in chemistry instructional activity, students solve 2 problems where they state all the answers as simple fractions or integers. They determine ratios of molecules in gasoline and they find ratio of molecules in the...

In this water on planetary surfaces worksheet, students read about the Galileo spacecraft and the surface of Jupiter's moon Europa. They read about the energy needed to keep the water in a liquid state on Europa. Students solve 4...

Learners study the water quality of a stream in their area, by measuring the temperature, pH, alkalinity and conductivity. They integrate biology with earth science when using the microscope to study the living organisms in the water.

Pupils study the importance of global ocean currents, sea water chemistry, and cultural issues surrounding sea ice. In the field, students travel to the floe edge with their teacher and an elder to drill holes in the ice and measure its...

Students examine a density demonstration involving ice cubes and beakers of water and alcohol. After observing how one ice cube floats in water and sinks in alcohol, they determine which mixture of the two would suspend the ice cube in...

Seventh graders perform an experiment to determine the effect of temperature on reaction rates. In this chemistry instructional activity, 7th graders take measurements and record data. They create a graph and analyze results.

Young scholars investigate reaction rates.  In this seventh or eighth grade mathematics instructional activity, students collect, record, and analyze data regarding how the temperature of water affects the dissolving time of a sugar...

Students discover that scuba diving is more than a sport. It's a science that operationally integrates physics, chemistry, physiology, and oceanography. They perform a simple experiment which simulates the air tanks used in scuba diving.

Students use red and blue litmus paper to determine the category of common substances. They then set up an experiment using vinegar, water, and ammonia (or milk of magnesia) to determine that acids make the best solution for dyeing...

Students estimate the size of a molecule of oleic acid. They conduct an experiment using chalk dust, water, and oleic acid, solve various calculations, and answer discussion questions.

Students collect data on causes of Acid Rain. In this science lesson, students simulate the effects that produce acid rain, collect and analyze data from their samples. They relate science and statistics in this lesson.  

Young scholars compare types of chemical change. In this chemical reaction lesson, students use a variety of household items to investigate different types of chemical change. Young scholars will engage in a discussion about the dangers...

Pupils examine how a sanitary landfill is constructed, how it functions, and how waste and leachate affects the areas around the landfill. After a discussion about landfills and leachates, students construct a Sanitary Landfill Model...

Here is a planet learning exercise in which learners read about organic molecules detected through spectral lines of the planet Osiris. They calculate the mass, the volume and the densities of common ingredients for planets including...

This isn't your typical basic lesson—it's more acidic! Learners use pH information to determine the hydroxide ion concentration of different substances and then use these values to analyze information. The calculations require...

In this units of capacity worksheet, learners read the word problems and solve the problems finding the metric units of capacity for each. In the 'use data' problem, students use the recipe to help them solve the problem.

Learners identify diffusion and its processes through experimentation and calculations. They also use a CBL and conductivity probe to measure the conductivity of various solutions and study the effect of concentration gradients on the...

Learners collect data, organize and analyze the data and compare it to real life scenarios. This assignment requires two class periods.

Pupils explore linear functions in this lesson when they collect and analyze data as a chemical reaction proceeds. Learners record pressure versus time data and model the data as a linear function. They also examine the concept of slope...

Pupils receive a miniature pumpkin and proceed through several stations to measure a variety of physical properties. The data is entered into a data sheet and the mass and volume measurements are used to calculate density. They also use...

Students use logic to locate the primary cases, the people who started the spread of the disease through the population. They graph the data of the number of people infected over time (exchanges) and determine an equation that best fits...
