Cooking is a beautiful tool to teach children science. Science can be tricky business, particularly because science is about seeing, experiencing and experimenting. Without these, it is difficult to appreciate why things happen and how they happen.
The best way to reflect how to teach science with cooking or while cooking is by using examples. Here are a 3 science questions to show how cooking can become an easy tool to teach simple science principles which perhaps the science lab could make it look like just another experiment.
Question 1
Mr. Butter Cake's class plans to bake a butter cake. Which of the following do you think is a science question that could be investigated while baking the cake? (A) Measuring the amount of flour and sugar? (B) Mixing and beating the batter? (C) Do butter cakes need baking powder to rise? (D) How much does it cost to make 2 butter cakes? The answer is C. We need baking powder to make a cake rise. Exp lanation: How does baking powder work? How does baking powder make the cake rise? Baking powder produces carbon dioxide. Carbon dioxide is a gas that will 'push' the batter side-ways and upward. They raise baked products. Flat cakes and biscuits don't look very tempting! Baking powder contains both baking soda and a dry acidic ingredient. Generally, 1 teaspoon of baking powder can be used for 1 cup of flour to help your cake rise.
Question 2
This question is about our senses. It is about looking, tasting, smelling and feeling.
Vinegar - Colorless, Sour, Wine, Watery - Liquid
Olive Oil - Yellow, No Taste, Wine, Oily - Liquid
Lemonade - Colorless, Sweet, Lemons, Watery - Liquid
Baking soda - White, Bitter, No smell, Dry powder
Which of Ann's senses allows her to differentiate baking soda from the other substances?
Answer: Sight, Taste, Touch
< p>Explanation: Children, in the first few grades learn about their senses and what they mean. Teachers would teach them about the 5 senses - Sight, Smell, Touch, Hear and Taste and would typically vary the questions to make children understand what they mean. In the kitchen, this comes to live. All the above substances and more are available in the kitchen. Make the kids smell, touch, look and taste. Perhaps for older kids, tell them about the nervous system and how information is passed to the brain.Question 3
Anna would like to drink some tea. She starts by boiling some water. Describe what happens to the water when she boils it? What happens if Anna places a metal lid above a pot of boiling water?
Answer: Water when boiled becomes steam. Steam or mist is invisible or colorless and tasteless. But when you place a metal lid above the boiling pot of water, the steam becomes water again. The processes are called evaporation and condensation .
The process of liquid turning into gas is called evaporation The process of gas turning into liquid is called condensation
Similarly, lots of everyday cooking actions is actually about science. You can turn your kitchen into a science lab and the best part is the kids will not know it. They are learning just as much in the kitchen and parents are helping kids remember better by allowing them to experience and see how science works in real life. Teaching kids while cooking creates a great opportunity to teach school work plus there is an added bonus. Kids and parents bond and build memories.

My daughter is 8-years old and they have to do a science fair project for their class. She loves animals so we have been trying to think of some ideas related to animals. We also have 2 cats so a project using them, we think, would be fun as well. Any suggestions for the project? Best answer for What is a good science fair project for a third grader?:
Answer by tangarineqt1946
theres always the environment experiment. for example you could put each cat in seperate rooms and test for like an hour or so. you could have one room with lights on and windows open with soft classical music playing..a relaxed, home-like environment and in the other room no lights, quiet or disturbing music like a tense environment. record their eating habbits (while in the rooms) and sleeping and things like that. i wouldnt make it too complecated if shes only 8 but it shouldnt be too hard. maybe do this for a week, 4 or 5 days? more ideas are online everywhere. sciencebuddies.com might have something...if not try google-ing something like "simple science experiment cats" or "easy animal science projects"
Answer by Zooey
Hi! I really can't think of any ones for cats, but I have these ideas if they help: Life Science Ideas: Plants and Animals --Have you noticed how the seeds in different kinds of fruit (like an apple and an orange) look very different from each other? Try growing seeds from different fruit or vegetables that you've eaten, soaking them in water for one night and then planting them in a cup of dirt. Which seeds do you expect to grow best? After doing the experiment, which seeds really grow best? (Which seed turns into the tallest plant after a month?) Why do you think that might be? --Lots of factors affect plant growth. Try experimenting with soil type, light, temperature, water, and more. (You might want to use Wisconsin fast plants, which will allow you to study the whole plant lifecycle in a short amount of time. --Does calcium really make our bones stronger? What would happen if we didn't get enough calcium? --What's the best way to wash our hands to keep us safe from germs? Use lotion and glitter or Glo Germ gel to simulate germs. --Have you ever watched ants carrying bits of food? What food from your kitchen do you think an ant or other insect would like best? What "bait" will probably attract the greatest number of different insect species? Can you test the effect of temperature on ants? --Do a project to find out if temperature affects brine shrimp. Do ones in a warmer environment develop faster than ones in a colder place? Is tap water, spring water, or distilled water better for hatching the eggs? --How does the membrane and shell of an egg help protect a baby chick? --Test green leaves to find out what other pigments are present in them. Chemistry Ideas: Crystals, pH, Slime, and Glue --Design a science fair project comparing and contrasting how long it takes ice to melt at room temperature compared to a warm stovetop or the refrigerator. Try thawing frozen fruit at the same time. Does it longer or the same amount of time to warm up as the ice? What if you add salt to the ice? --Your kitchen offers lots of chemistry ideas. How does cola or another soft drink compare in acidity with other common drinks or food? You can test acidity using pH paper. You can also use indophenol to test which fruits have the most vitamin C. --Water is sometimes called "the Universal Solvent'' because it dissolves other substances so well. How well does water dissolve salt or sugar compared to other liquids (like oil, corn syrup, or vinegar)? --Experiment with surface tension by making bubbles. Can you make them in different shapes? Can you poke scissors through them without popping them? --Make crystals from sugar, salt, and baking soda. How do their crystal shapes compare? Does the rate of evaporation of the crystal growing medium (water, vinegar) affect the size of the crystals? Does the rate of how fast the crystals cool down affect the size of the crystals? Do impurities (such as iodized salt versus salt that is not iodized) affect the growth of the crystals? --What happens when saltwater from the ocean evaporates? --Chemical energy can produce power! Try making a battery from food items. Which type of citrus fruit works best? What about vinegar? --Experiment with polymers by using milk proteins to make homemade glue. How does homemade glue compare with glue from the store? Can you develop a way to make homemade glue stronger? You can also make homemade slime. Does more or less of an ingredient make the slime more stretchy? What about slippery or gooey? --Why do apple slices turn brown? Can you stop this from happening by using lemon juice? What else could you use? --How does yeast make bread rise? What conditions make yeast react faster or slower? Earth Science Ideas: Weather and Dirt --The sun causes water to evaporate into the air, where it forms clouds and comes back down as rain or snow. Can wind speed, humidity, or temperature have an effect on the rate of evaporation? (Do one of these weather experiments to find out more.) --How good is soil at breaking things down? What can you find that is biodegradable? How can you test to see whether something is or not? --What holds more water, sand or soil? How does this affect what kinds of plants can grow in each? Can you learn to predict the weather from the clouds? Try using a cloud chart to make your own forecast every day for a few weeks. How accurate was the cloud-forecast method? --How does a thermometer work? What kind of liquid works best to show changes in temperature? Physical Science Ideas: Force and Energy --Can you use a magnet to find traces of iron in food, dollar bills, and other household materials? Are some magnets stronger than others? --What type of flooring creates the most or the least friction? Try carpet, wood, tile, linoleum, etc. Younger kids might test this by rolling a ball or toy truck over different surfaces. (Or use a spring scale to measure the force o
