Self-Inflating balloons 

Materials:
Test Tube 
Vinegar 
Small Balloon 
Funnel 
Teaspoon Of Baking Soda 

Experimental Procedure 
<span>1. Put the test tube where it will stand upright securely, or have a partner hold it. Fill it halfway with vinegar.
2. Give the balloon a good stretching, like you would if you were about to blow it up.
3. Use the funnel to put the baking soda inside the balloon. Gently shake the balloon until all the baking soda goes to the bottom.
4. Making sure none of the baking soda gets into the test tube, carefully stretch the opening of the balloon until it’s completely over the opening of the test tube. If it’s not a tight fit, your balloon is probably too big and you should use a smaller one instead.
5. Once the balloon is attached to the test tube, lift the rest of the balloon so that the baking soda falls into the vinegar. You might have to give it a gentle shake to make sure it all goes in.
<span>6. Watch the balloon inflate! What’s happening here is the vinegar, an acid, is creating a chemical reaction with the baking soda, a base. When the two substances mix, you get carbonic acid, which is unstable and decomposes (falls apart) to become carbon dioxide (the gas that’s filling the balloon!) and water. Since the carbon dioxide is much less dense than the stuff you used to create it, it wants to expand, and the balloon is stretchy enough to allow it to do just that!

Lea wants to maintain strong bones as she ages. Which bone-strengthening activity should she incorporate into her current plan?
ruslelena [56]

Running and aerobics are bone-strengthening activities that Lea may incorporate in her current plan. However, the kind of bone-strengthening activities that should be done depends on the stage of development. For children, adolescents and young adults, vigorous activities may be done because it is the stage for building strong bones. On the other hand, adults aged 35 onwards have the tendency to have brittle bones or natural bone loss, therefore, vigorous activities must be lessened in frequency.
