How does temperature affect lipase activity? Young scholars conduct an experiment to collect data on the interaction of lipase at different temperatures. They add lipase to a solution of milk, sodium carbonate, and phenolphthalein and...

We know plants assist in the water cycle, but how do plants get water from the ground into the air? Through a series of demonstrations or labs, scholars observe the movement of water through plants. They microscopically view the cells...

A resource rich in information—and nutrients. Learners create agars for the purpose of cell cultivation in Petri dishes. The lesson provides instructions on how to create agars for the cultivation of different microorganisms.

How well can your class concentrate on solutions? Scholars use colorimeter absorption to explore a starch concentration calibration curve. They add iodine to different starch solutions to see how the concentration of the solution changes.

Join the fight against bacteria. An open investigation shows pupils different aspects of antimicrobial substances, such as disinfectants, deodorants, or plant oils. They design and conduct their own experiments on the effectiveness of...

Cultivate bacteria with a straightforward lesson featuring agar. Scholars create a streak plate on agar to ideally create colonies of bacteria or yeast that are growing separately from each...

There's no need to water down the resource. A tutorial takes learners through the process of creating dilutions for any solution. Specifically, it focuses on serial dilutions with successive factors of 10.

Don't let your bacteria go to waste. A tutorial explains how to properly store and maintain bacterial stock cultures. It describes the purpose and preparation of a permanent stock, as well as a working stock for use in experiments.

Everyone wants to feel like they belong. James, in James and the Giant Peach, finds a feeling of belonging in a very odd place—inside a peach! Scholars read the story of James and the Peach and work through vocabulary, language, and...

Out of all animals, elephants alone lack the ability to jump. Scholars learn all about animals using a presentation full of fun examples. It describes different types of animals, the biological similarities and differences between...

After the lab, you'll be able to solve this analogy: Natural selection is to vertical transfer of genes as ___ is to the horizontal transfer of genes. Young biologists conduct an experiment on E. coli bacteria to explore the process of...

Keep clam and read on! After reading the textbook selection about mollusks and worms in the additional materials section, your young zoologists check their comprehension by answering the questions on the handout found here. To...

Use this activity as an anticipatory set to warm up for a lesson on predator/prey relationships. Pupils will play a round of "Duck, Duck, Goose," substituting the ducks and geese for two animals that have a predator/prey relationship....

Despite the typos and formatting issues, the Word document found here has some great potential. There are two questions that ask learners to put several events in a logical order; these could easily be made into a card sort activity....

Third graders examine soil samples and explore the what happens in each layer of the subsoil. They work in cooperative groups to create a scroll that shows what takes place in each layer, and discuss why much of the activity is in the...

Ninth graders will identify/understand the differences between soil and dirt. They will classify soil color accurately and use Munsell notation to describe it (Munsell books provided).Students will classify soil texture using the feel...

Text marking and a T-chart format to distinguish important information from trivia help elementary readers summarize effectively. Encouraging readers to construct a chapter summary from paragraph-level topic sentences is another sound...

Students read and discuss decomposers and how they affect the environment. In this decomposers lesson plan, students also discuss how engineers use decomposers to help the environment.

Students create a worm bin full of fruit and vegetable scraps wit paper and observe what happens over time. In this decomposers lesson plan, students observe that the fruit and vegetable scraps become new soil.

The World of Living Things is the focus of this biology presentation. Students view a presentation which introduces them to cells, parts of cells, microorganisms, and simple vs. complex animals. They see that they are classified as a...

Burrowing animals are busy! Get your middle school ecologists busy as well by having them create a scale model of a burrowing population. They also design a PowerPoint or poster to explain their models. 

Take your enthusiastic ecologists outdoors to explore the biodiversity right in their own schoolyard! In preparing for this activity, it may be worthwhile to research websites with local flora to help in the plant identification...

Are you looking for a way to measure cellular respiration? Try it with pureed potatoes. With some standard high school science equipment, biologists can perform an investigation and collect data surrounding byproducts of respiration. You...

Like good scientists, kids often want to see first-hand why things are as they are; they can do just that in the starch-testing photosynthesis activity found here. Depending on the age of your pupils, you may wish to do the investigation...
