Model and explore osmosis using squash and potatoes. Young scientists expose chunks of potatoes to different concentrations of a squash solution. They compare the weights of the chunks before and after exposure to the solution and use...

Over a period of 35 years, earthquakes and volcanoes combined only accounted for 1.5 percent of the deaths from natural disasters in the United States. The 15th lesson in a 20-part series connects the locations of earthquakes and...

It's rare for even 40 percent of test takers to pass the AP Physics 1 exam. Improve those odds for young scientists with the help of actual free response questions covering topics from free body diagrams to velocity. The College Board...

Here's a stat for your pupils: 18 percent of the human body is carbon! Part 10 in the series of 12 takes pairs on an adventure through the carbon cycle. After a class reading about carbon, pairs read and choose their own adventure...

More than 80 percent of the earth's surface originated from volcanoes. The 16th lesson in a 20-part series introduces the shape and development of volcanoes. It begins with a demonstration using a balloon and flour to illustrate the...

The I-STOP law was designed to regulate the distribution and tracking of prescription drugs. After reading an article about its signing and implementation, middle and high schoolers work together to come up with their own ideas for an...

A scenario is presented for chemistry techs to address. Using titration techniques, they must analyze hydrogen peroxide solution samples. They evaluate accuracy and precision in the process. They also gain experience consulting the MSDS...

Thirty percent of energy used by schools is used inefficiently! Part two in the series of 12 has groups perform energy audits of their schools as part of the Cool Schools Challenge. Each group is assigned a specific room, performs the...

After a whole-class discussion of water reservoirs, ten liters of water are given to each lab group to represent Earth's total amount of water. They divide the water into smaller containers, each representing one of those reservoirs. The...

The devastating changes happening to the Native American inhabitants of an island off the coast of Louisiana are the topic of an informational lesson. After scholars break into groups to explore particular topics, they come back together...

Do you have mole problems? If so, call Avogadro at 602-2140. The lesson starts with pupils working independently to solve for molar mass of ionic compounds. Then they learn to solve for percent composition and later perform an...

In the sixth lesson in a series of 21, scholars use NASA data to graph and interpret albedo seasonally and over the course of multiple years. This allows learners to compare albedo trends to changes in sea ice with connections to the...

Students start to think of evolution in terms of populations. The class follows a cartoon scenario of a rabbit population in which there is selection and change of gene frequency. They receive copies of the scenario or the whole thing...

Try not to blind anyone with science by following the safety rules. The lesson encourages scholars to form an ionic compound from magnesium and chlorine. Then they determine the empirical formula and determine the mole ratio and percent...

Students calculate how much coal they use based on their electric power usage. In this environmental science instructional activity, students trace the history of coal mining in US. They write a letter to USPS to encourage them to create...

Forty percent of food in the US goes uneaten while 14.5 percent of US households lack a secure supply of food. As part of the preparation for a performance task assessment, groups consider statistics such as these about food waste and...

In this chemical compounds activity, students learn the steps for determining the empirical formula of a compound and then complete 3 problems.

Students are presented with the problems of percentages and focus upon numbers in contrast to 100. They calculate problems with money and are engaged with the use of games as a teaching tool. Students also interpret data as presented in...

Students explore finding the percent of a numbers. They survey their peers to determine modes of transportation used in getting to school. Afterward, students organize information and create graphs and charts. They explore alternative...

Students explore the circulatory system. They participate in media activities to explore blood flow and identify the parts of the circulatory sytem. Students create a model of the circulatory system.

Students identify the inside parts of a dog salmon in English and Athabascan. They weigh each part of the salmon and determine the percentage of the whole that the part represents.

students research blood's components, and use their math skills to recreate a model of whole blood using commonly found food items.

In this Agriculture Day worksheet, learners complete activities such as reading a passage, phrase matching, fill in the blanks, correct words, multiple choice, spelling, sequencing, scrambled sentences, writing questions, survey, and...

High schoolers examine the concept of radioactive dating. In this radioactive dating lesson, students investigate how to determine the ages of fossils and rocks as they learn about half-life radioactive decay.
