The Everything Kids' Science Experiments Book: Boil Ice, Float Water, Measure Gravity-Challenge the World Around You!
Format: PDF / Kindle (mobi) / ePub
Science has never been so easy--or so much fun!
With The Everything Kids' Science Experiments Book, all you need to do is gather a few household items and you can recreate dozens of mind-blowing, kid-tested science experiments. High school science teacher Tom Robinson shows you how to expand your scientific horizons--from biology to chemistry to physics to outer space.
You'll discover answers to questions like:
- Is it possible to blow up a balloon without actually blowing into it?
- What is inside coins?
- Can a magnet ever be "turned off"?
- Do toilets always flush in the same direction?
- Can a swimming pool be cleaned with just the breath of one person?
You won't want to wait for a rainy day or your school's science fair to test these cool experiments for yourself!
experiment, you can repeat it by making more measuring scales and actually predicting the upcoming weather. Congratulations! You are a meteorologist! meteorologist: a person who studies and reports weather conditions. CONCLUSION If air pressure increases, the outside air will press down on the water in the pan and push it up into the bottle. This will produce an increase in height of the water. When weather forecasters use the term “inches of mercury,” they are using a similar scale

observe the changes in the balloon. Remove the bottle from the water and let it sit at room temperature for 10 minutes. Remove the balloon from the top of the bottle. Place the funnel in the mouth of the bottle and tape the mouth of the bottle to the funnel so that no air can escape. Pour water into the funnel and watch what it does. WHAT’S HAPPENING Air definitely takes up space! When you first put the balloon on the bottle, you “captured” the air that was in the bottle. It didn’t
light to grow? EXPERIMENT OVERVIEW You’ve already seen what happens to some trees when they don’t get enough light — they lose their leaves. But plants and trees are different. In this experiment, you’ll get to explore whether or not seeds and plants need light to grow by placing some seeds and plants in the dark while others stay in the light. You will decide whether or not light makes a difference in their growth pattern. This experiment will take a few days since most processes with plants
what you are comfortable with. Pick an activity you can do safely. Choose the length of the test you wish to perform and find your pulse again. Compare your resting pulse with your pulse after exercise. Fun Facts People should exercise so that their heart rate is between 60 percent and 90 percent of their maximum rate. QUESTIONS FOR THE SCIENTIST What was your resting pulse? Which result(s) did you use to come up with this number? What was your pulse after exercise? What are the
