Testing Growth of Algae

Bubble, bubble, boil and trouble! What causes common substances like baking soda and vinegar to react the way they do? Welcome your junior chemists to the wonders of acid-base chemistry using a comprehensive and fun resource. Engage them...

Here is a fabulous set of teacher's notes that will make your next hands-on gravity and force lab fun and interesting. These notes provide you with three activities that allow children to make and test hypothesis regarding force,...

Learners use a Colorimetric test to measure pH and gain the importance to life in an aquatic ecosystem pH is. They explore the dramatic effect pH level can have on a water body. Students test the pH level of many water samples.

Identify natural resources in the world and how they translate into economic development. In this global economy activity, your class will utilize the Internet to view an Oregon Time Web which they research to examine the history of...

Students discover algae. In this science lesson plan, students examine what green algae is and where it grows. Students test the growth of algae in four different types of water: lake water, well water, distilled water and tap water

Learners observe the effects of eutrophication and determine why it is harmful to aquatic ecosystems. They create mason jar ecosystems to observe the growth of algae in pond water. In addition, they observe the effect of introducing...

A 12-page midterm exam sample can be given to young scientists in preparation for an exam. This particular installment is geared toward a class that delves into both ecology and chemistry concepts. There is no way to separate the 50...

Middle schoolers observe the growth of yeast cells, which is evidence that yeasts are converting food to energy and are living organisms. They build an apparatus to show that yeast produce carbon dioxide. Students observe yeast with...

Students conduct a variety of experiments to explore protein. In this biology lesson, students solve a mystery by testing for the presence of glucose, protein starch and triglycerides. They explain how DNA transcription and translation...

Students determine the effects of an increase of the amount of nitrate and phosphate levels on the growth of algae. the development of a hypothesis is encouraged and students proceed to a conclusion based on their results.
