Scholars shake their way to understanding half-life with the help of candy. They observe and record which side candy lands on to graph the exponential decay in the fifth lesson of seven integrating chemistry and algebra. Combining...

Scholars will be in their element with these decay equations found in a video that solves an example of alpha decay and beta decay. Gamma, or light, emission adds an extra concept to the equation. Then, through an analysis of which...

Scientists can't just change a neutron to a proton, can they? Although they don't have control of this process yet, they have identified the weak force that does exactly that. The simple graphics in an interesting video explain the...

Dead trees provide nutrients for the soil, food for animals, protection and a home for organisms, a seed-bed for new trees, and a place for nitrogen-fixing bacteria to live. In the activity, pupils collect decaying logs, expose them to a...

Does Newton's Law of Cooling have anything to do with apples? Scholars apply Newton's Law of Cooling to solve problems in the 29th installment of a 35-part module. Now that they have knowledge of logarithms, they can determine the decay...

A lesson prompts scholars to use candy to figure half-life. Combining class data allows them to find the graph of best fit and to determine if it should be linear or exponential. 

Behold the rotting tomato! In one minute, watch as a tomato shrivels and molds into nastiness. In reality, this took two months.

The teacher illustrates two different exponential tables and explains what each one of them means. These are function tables, one demonstrates exponential growth and the other exponential decay. She clarifies how to analyze the...

The instructor first identifies what formula to use to solve this word problem. Then she explains what each of the variables stands for and helps match up their given values in this word problem. There are many components to solving this...

Even the witch in Snow White had a better looking apple than this! Watch as mold spreads, consuming and rotting a once red apple. May you never have to see this in your lunch box. Show the video instead of attracting fruit flies into...

Prepare to be disgusted as a bowl of fruits and vegetables decomposes in a matter of minutes! This video, taken over 74 days, shows the mold and decay, complete with fruit flies. Great for a biology or even nutrition class!

The question posed for the class to consider; What would decay and what would not? They read the short passage on decomposition and microbes, then mark the items that would decay after a two-week period. A scientific investigation idea...

Written to accompany another slide show available through our site, the information here gives the history and trivia connected to nuclear decay research. This slide show concentrates on the definitions and theory of nuclear fission and...

Young scientists use a worksheet to help them perform a lab on the decay of a radioactive element. The worksheet serves as both a task guide and a lab sheet for pairs of learners. This activity requires a calculator and has excellent...

In this nuclear chemistry activity, learners define radioactivity and the types of nuclear reactions. They label nuclear reactions with one of five types of reactions including fusion, fission, induced, natural decay or electron capture.

Which ones can be thrown on the ground? Discover the difference between natural litter and unhealthy trash, helping scholars by using several examples. Use the information here to give them a basic background, but also encourage prior...

Students work with the scientific method; observation, hypothesis, and experimentation. They observe the effects of decay and the need of good oral hygiene during an experiment with an apple.

Ecology explorers or beginning biologists view a time-lapse film of decaying strawberries. They discuss how decomposition occurs and what factors might affect the rate of decay. Alone, the lesson plan is lacking engaging attributes....

In this half-life worksheet, students determine how long it takes for a 100g sample of AU-198 to decay to 6.25g. Then they determine the half-life of a radioactive isotope if a 500.0g sample decays to 62.5g in 24.3 hours. Students also...

Students investigae using radioactive decay to determine geologic age.

Students observe and listen to nonfiction books about the life cycle of pumpkins. They practice early reading skills in a shared reading related to pumpkins. They observe the life cycle of a pumpkin including growth and decay.

In this "Ozymandias" worksheet, students discuss the theme of transience. Students answer four questions about permanence and decay in the world. 

Young scholars become better aware of their anatomy, development and function of their teeth.  In this healthy mouth lesson students view a slideshow and complete several activities. 

Students analyze the causes of corrosion. In this chemistry lesson, students investigate what is necessary to cause chemical changes in matter. Students discover the causes of rust and tooth decay.
