Materials: 1. Half a lemon 2. Water 3. Spoon 4. Bowl 5. Cotton Bud 6. White Paper 7. Lamp Steps: 1. First, squeeze the lemon juice into the bowl and add 6 drops of water. 2. Next, mix the water and lemon juice with the spoon. 3. Then, dip the cotton bud into the bowl and write a message onto the paper. 4. Next, wait for the juice to dry. 5. Finally, heat the paper by holding it close to the light bulb to see the message. Lesson: Lemon juice is a substance that oxides and turns brown when heated. Other substances which work in the same way are orange juice, honey, milk, onion juice, vinegar, and wine. Invisible ink can also be made using chemical reactions or viewing the message with a UV light.
Materials: 1. Mixing spoon 2. Mixing bowl 3. Food coloring 4. 1/4 cup of water 5. 1/4 cup of white craft glue 6. 1/4 cup of liquid starch Steps: 1. First, pour the glue and water in the mixing bowl. 2. Next, stir the glue and water together. 3. Then, add 6 drops of any food coloring of your choice. 4. Next, add liquid starch and stir. 5. Finally, play with the mixture until it becomes stretchy and store it in a zip bag when you are not using it. Lesson: The glue is a liquid polymer, which means that the glue has tiny molecules connected together in a chain. When you add the liquid starch, the polymers of the glue hold together making it slimy. The starch helps link all the polymer strands together creating slime.
Bill Nye, “The Science Guy”, has some great “home demos” which could certainly be used in the classroom, along with some printable “one sheets”.
#scichat #spedchat #elemchat
Home Demos are found in three categories; life sciences, physical sciences, planetary sciences.
I have added these to Super Science Fair Project Resources

Materials: 1.granulated sugar 2.food coloring 3.stovetop safe container 4. Cream of tartar 5.candy thermometer 6.light corn syrup 7.water 8.adult 9.aluminum foil pan 10.measuring utensils Steps: 1. First, add one and three forts of sugar in the stove top safe container 2. next, add 1 cup of water 3.then, add half a cup of corn syrup 4.next, add 1/8 teaspoon of cream of tartar 5.then, combine all the ingredients 6. Next, slowly heat the heat the mixture at a low boil while stirring 7.then, keep the mixture add a low boil and please a candy thermometer in the container. 8.next, keep the mixture boiling until the temperature reaches 300 Fahrenheit 9.then, pour the mixture into the foil pan 10.next, add food coloring to the pan and spread the colors 11.finally, let the mixture cool until hardened. Lesson: This experiment is used in candy making. When you add corn syrup, it prevents the sugar from re-crystallizing. The cream of tartar separates the sugar crystals into glucose and fructose, which are simple sugars. The light that passes through the translucent sugar glass will take the colors from the food coloring you choose
Meteors become meteorites when they hit the ground. Hundreds of meteors enter earths atmosphere every day, very few of them hit soil.

This is a homopolar motor.
It’s really easy to experiment with at home. It is driven by the Lorentz force - the force which is exerted by a magnetic field on a moving electric charge. When a battery is placed on top of a magnet, and a wire then connects the top of the battery back down to the magnet, the circuit is complete.
Students in our Summer Schools were making these the other day. This one won the ‘most creative design’ competition <3

Hi everyone! I'm Ashley P. and I'm a Girl Scout who wants to make a difference in the world. Currently, I've been working on my Gold Award Project, which is a project where Girl Scouts solve an issue in their community to earn the Gold Award. The Gold Award is the highest award a Girl Scout can achieve. In my project, I'm addressing the issue on how there are a lack of women in the STEM field by creating a program to do fun science experiments with younger girls. Also, I constructed this blog for parents and children to do exciting and simple experiments with their kids to spark a passion in this subject like what happened to me as a child. I hope you enjoy and try to accomplish the experiments I post! Also, please have adult supervision while completing these experiments.
