Learners investigate reaction rates.  In this seventh or eighth grade mathematics lesson, students collect, record, and analyze data regarding how the temperature of water affects the dissolving time of a sugar cube. Studetns...

Predict outcomes using linear models. Young mathematicians strengthen their understanding of slope and linear models using a hands-on activity. They monitor the dissolving rate of bouillon cubes, graph their data, and make predictions...

Students conduct experiments with plants.  In this photosynthesis lesson, students examine plants under different types of lights.  They calculate the amount of dissolved ocygen concentration and compare it to the formula for...

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...

Many math concepts are covered through this resource: percentages, decimals, ratios, exponential functions, graphing, rounding, order of operations, estimation, and solving equations. Colorful worksheets and a link to a Google search for...

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.

Ease children's back-to-school jitters with this primary grade instructional activity based on the book The Kissing Hand by Ruth E. Harper. Starting off with a singing of the song "I Wish I Had a Little Red Box", children go on...

Students observe the growth of rock candy. In this crystal growth instructional activity, students make rock candy and measure the crystal growth over five days.

Students design and conduct investigations that illustrate the effect bioremediation has on organic matter and determine environmental applications. They, in groups, present their findings to the class.

Students determine how the temperature of water affects the dissolving time of a sugar cube. They create, interpret and analyze graphs of data, find an equation of the line of best fit, and relate slope to rate of change.
