#### Weak Interaction: The Four Fundamental Forces of Physics #2

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...

Lesson Planet: Curated OER

#### The Secret of Life

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...

#### WS 6.1 Nuclear Particles and Reactions

In this nuclear chemistry worksheet, students 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.

Lesson Planet: Curated OER

#### Good Litter, Bad Litter

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...

Lesson Planet: Curated OER

#### Observing the Pumpkin Cycle

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.

Lesson Planet: Curated OER

#### Time Lapse - Tomato

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

Lesson Planet: Curated OER

#### How Do You Identify Exponential Behavior from a Pattern in the Data?

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...

Lesson Planet: Curated OER

#### The good microbes

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...

Lesson Planet: Curated OER

#### Nuclear Reactions Answers to Questions

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...

Lesson Planet: Curated OER

#### Plaque Busters

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.

Lesson Planet: Curated OER

#### Casual Patterns in Ecosystems

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....

Lesson Planet: Curated OER

#### Half-life Worksheet

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...
