Science: Can we Change the Color of a celery?

Today's Lesson: Can we change the color of a celery?  

STANDARD 5.1 (SCIENTIFIC PROCESSES) ALL STUDENTS WILL DEVELOP PROBLEM-SOLVING, DECISION-MAKING AND INQUIRY SKILLS, REFLECTED BY FORMULATING USABLE QUESTIONS AND HYPOTHESES, PLANNING EXPERIMENTS, CONDUCTING SYSTEMATIC OBSERVATIONS, INTERPRETING AND ANALYZING DATA, DRAWING CONCLUSIONS, AND COMMUNICATING RESULTS.

In class we dicussed the process of experiementing and talked about how it applied to us everyday. We talked about the plants and created a brace map to identify the parts of a plant and their functions. Going about this we did an celery experiment to help us better understand the functions of a plant.   

Things we need: 

•  Tall Clear Glass jar
• Water
• Red Food coloring or other colors
• Scissors
• Observation sheet
• Celery sticks with leaves

Doing this experiment helps students better understand and observe how Plants use their roots to absorb water. Using the food color into water helps track where the water is going inside the celery. 

Students first had to find a tall clar glass jar to add water into. Each team had two jars, one with plain water and the other with food color added to it. Next the team got two celery sticks with leaves and cut the buttom of the celery about 1/2 an inch. After this we talked about what we think might happen. The students drew a before and after perdictions. 

Here are some pictures of our Little experiment the children enjoyed!
