All sodium carbonate may not have the same amount of carbonate, but it should have the same percent. Learners write and balance an equation to predict the chemical reaction between sodium carbonate and zinc acetate. Through the lab...

NASA presents a mini-unit on distances in our solar system. It incorporates scientific concepts of gravity, mass, density, and payload while your aspiring astronauts also employ mathematics skills. They calculate speed, they determine...

In this stoichiometry worksheet, students use balanced equations for chemical reactions to determine the percent yield and the mass of product produced. This worksheet has five problems to solve.

Young learners explore nutrition and the food groups in these two mini-lesson plan ideas. First, kindergarteners have a discussion about their health and how different foods contribute to it before making their own personal food pyramid....

The third lesson in a series of 11 begins by using thermal decomposition of potassium chlorate to determine the mass percent of oxygen. Then a second activity allows scholars to demonstrate that the resulting residue is from a...

This hybrid worksheet connects mathematics to a science class. Learners practice solving problems that involve making a variety of conversions. An assortment of questions hits all the calculations needed for a middle school or beginning...

Pairs simulate the energy usage of different countries by drawing beads from a bag, which contain different beginning ratios of non-renewable and renewable energy resources. The activity concludes with a series of questions to tie...

What happens when you combine 6.022 times 10 to the 23 piles of dirt into one? You make a mountain out of a mole hill. Scholars use dehydration to obtain percent composition and then calculate the molarity of the original...

Scientists require specific chemical solutions for their experiments. In the seventh and final installment in a series that integrates chemistry and algebra II, scholars learn to set up a system of equations to solve the volume of a...

The introduction to the lesson mentions a sailor's limited capacity to store drinking water on his ship. Pupils then set up an overnight experiment to remove freshwater from salt water by distillation. There is a math and map activity to...

Students examine and compare traits of humans and crocodiles.  For this crocodile lesson students use a ratio to estimate the height of a person and compare that to a crocodile. 

Young scholars find the constant of proportionality and apply it to a situation. They use the electrical resistance in a wire as a context for finding the constant of proportionality. In addition, they write an explanation and...

Students explore types of water reserves. In this water conservation lesson, students brainstorm ways water are used in their homes. Students use a graduated cylinder to simulate the amount of water on Earth and the amount that humans use.

Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...

All soil is not created equal! A lab activity asks learners to collect and analyze soil. Specific calculations determine the amount of sand, silt, and clay in a sample and allow individuals to identify the soil texture. 

Roy John Britten easily earned a PhD in nuclear physics—but he found painting with water colors too difficult. Young scientists learn about Britten's life, career, and research with an online interactive. They read a biography, view...

Pupils discuss as a class the need for a healthy diet. They bring in a food product and analyze the nutrition label. Using the labels, they complete a worksheet and chart the nutrients found in beef. They use a scale to see how close...

Third graders discuss light sources and collect data about energy sources. They compare data and create a multiple line graph showing energy used by light sources for each student in the group. They present their graphs and write a...

Students develop an awareness of the effect of pandemics and acquire knowledge to prevent a pandemic from spreading. In this pandemics lesson plan, students build research skills using a variety of sources. Students investigate...

Third graders model the tag and recapture of bears and use proportions to estimate the population of the bears in their forest. This is a statistical sampling method used by scientists and naturalists to determine population numbers.

Students calculate proportions to determine the total population of Lake Pepperidge Farm. They collect a blind sample of fish and count the number of tagged and untagged fish. They collect data from all samples and record the data in a...

Aspiring astronomers solve problems involving mixed units of the same attribute, including time, money, length, and area. They convert large numbers into scientific notation, then compute and compare ratios to explain why drawing...

Studets practice problem solving and comparison of quantities, ratios and prproportions. They develop a plan for determining the height of a flagpole complete with drawings and calculations. In addition, they complete a written...

Students explain why a transiting planet causes a periodic dimming in the light from its parent star. They determine the radius of a planet, and its orbital distance, by analyzing data and manipulating equations. Students compare the...
