Health science lesson plans: Nutrition chemistry and recipes to fight obesity

Childhood obesity is a dangerous health issue that affects more kids annually. What can we as parents and teachers do about it? Weight loss under age 13 is tricky because preteens are still growing. Better to teach good nutrition in health and science lesson plans. Here are healthy food swaps for favorites kid foods and ways to teach nutrition in the classroom. 

* Salt: Teach properties of salt in kitchen chemistry lesson plans. Teach children to read labels and seek out low-sodium varieties of favorite snacks. Put out healthy snacks and let kids make trail mix in snack size bags to control portions. Make low salt popcorn in class. For fun nutrition lesson plans, instruct kids to research salt substitutes--lemon juice, vinegar and herbs.

* Soda pop. Have students study nutrition labels to discover how much sugar pop contains. In chemistry
science lesson plans, demonstrate how sugar dehydrates, and how the acid in pop burns grime off a penny and in the same way burns stomach lining and tooth enamel. Help students create healthy carbonated drink recipes with 100 percent fruit juice and soda water. Demonstrate the importance of plain water in curbing obesity and overall health. 

* Pizza: Kids love pizza and there are a million great ways it can be used in lesson plans. Let students make clock faces with vegetables and cheese on personal crusts. Experiment with creative pizza recipes using healthy toppings and creative crust food swaps. Made right, pizza can actually fight childhood obesity. 

* Veggies and dip: Kids love vegetables in ranch dip so let them invent healthy dip and dressing recipes. Use food swaps of yogurt, garlic, pepper and a little Parmesan cheese. Teach colors and patterns with cut vegetables. Help them to explore texture and taste and then write descriptively. 

* Spreads and condiments: This is a great place to learn measurement and portion size. Let kids practice measuring serving sizes of ketchup, jam for PBJ, butter, mayo, etc. Explore calories and teach math by counting and adding calories in math lesson plans. 

* Breads: Help kids explore healthy vs. unhealthy ingredients in breads. Bring in your bread machine and use it to teach cooking, nutrition and kitchen chemistry lesson plans. Help kids invent and write nutritious bread recipes using different grains, nuts, seeds and dried fruits. 

No nutrition lesson plans are complete without the fitness component. Get kids away from screens and outside playing. Active children will not need to worry about weight loss and obesity.
