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,...

An outline walks your scientists through the steps of the scientific process. It begins by taking a general idea and developing a hypothesis based on related factors. Each investigator then plans a method for testing the hypothesis,...

Playing follow the leader has never been so interesting! Get the class up and moving while they take on the roles of nervous system components. Through trial and error, they learn the importance of the "pioneer" growth cone that leads...

Test the efficiency of your memory! Scholars test each other's memory as they explore factors that affect memory retrieval. Through experimental analysis, they discover there are different types of memory, which has an impact of the...

Identify natural resources in the world and how they translate into economic development. In this global economy lesson, 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

Students 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 and...

Students 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...

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.
