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...

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.

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,...

Students compare water quality of different sources. They test water samples for odor, phosphates, pH, bacteria, and dissolved solids. they fill out a data table and answer questions about their findings.

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...

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

Young scholars 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...

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...

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

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...
