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,...

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 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...

Young scholars 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.

Students perform an experiment where they learn how water can be polluted by algal bloom. They grow algae with different concentrations of fertilizers or nutrients and analyze their results.

Can corn power the world? Young scientists learn about how corn and other plants can provide renewable biofuels in the second of nine lessons. They set up an experiment to investigate how different variables affect plant growth. All of...

Middle schoolers build an apparatus to look at how yeast cells grow by converting food to energy. They observe yeast both with and without food and see how yeast produces carbon dioxide.
