Scientific Method and Crystal Growth

Plants need food to survive, just like any other living organism. Young biologists analyze an experiment performed in 1610 by Jan van Helmont to determine if plant nutrition is obtained through the soil. First, lab groups work together...

Can your classes solve the problem of the smelly sweat sock? Young scientists complete a lab investigation that begins by using electrochemistry to generate colloidal silver. They use their solutions to test the rate of microbial growth...

What an exciting lab experiment to conduct with your high school chemistry class! Crystals are formed naturally in the environment. However, allow your blossoming chemists to create their own unique crystals using alum and water. You may...

In this biology worksheet, students review the characteristics of life and the scientific method. This worksheet has 19 fill in the blank, 6 matching, and 2 short answer questions.

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,...

Students think about the historical development of the scientific method. They design an experiment that replicates van Helmont's, using only specified materials. Pupils then improved upon van Helmont's procedure and also consider the...

Emerging ecologists need a full understanding of life, from the inner workings of a cell to the complex relationships among organisms. This examination is meant to assess high schoolers after an entire year course on the living...

Make reviewing evolution, cell division, genetics, cell structure, and scientific method more fun! Science Jeopardy allows teams to choose a category for the question they will address. If you complete the entire game, learners will have...

Students explore the different phases of a crystal.  For this mineral lesson students grow their own sugar crystals using a sugar recipe. 

Students conduct a webquest on an energy source they chose. In this physics instructional activity, students design an experiment to determine the factors affecting potential and kinetic energy. They calculate speed and create distance...
