Kids are naturally curious, and they love to see science in action. Summer is the perfect time for learning outside in the sun. Here are some easy projects that you can make at home with your kids:
Fizzy Sidewalk Ice Chalk
-corn starch 1/2c
-baking soda 1/2c
-liquid water colors- a few drops
-spray bottle with vinegar
Gently mix the first four ingredients together. Make a few batches so you can use different colors. Fill trays then freeze for 6 hours. Use it like any other sidewalk chalk. For extra fun spray the chalk with vinegar, and watch as the ice bubbles turning the solid into a gas.
Learning: states of matter- liquid, solid, and gas.
-Alka-Seltzer- 1/2 tablet
-Small Canister like a film container or any similarly sized plastic container with tight fitting lid
-Glue Dots (or Chewed Gum)
-Construction paper, tape (optional)
(Optional- cut and color construction paper attaching it to the plastic canister to look like a rocket.) Then attach the glue dot to the inside of the lid and then firmly press the Alka-Seltzer onto the glue dot. Fill the canister halfway with water. Firmly press the lid onto the canister and turn it upside down (so that the lid- side is down) then quickly place it on a level surface. Stand back and watch how high your rocket soars.
Learning: Chemical reactions creating gas (carbon dioxide) which causes pressure in the canister causing it to launch.
Rainbow Density Jar
-Corn Syrup 1/4c
-100% Maple Syrup 1/4c
-Dish soap 1/4c
-Olive oil 1/4c
-Rubbing Alcohol 1/4c
Start by pouring honey in the jar to form the bottom layer, don’t get any on the sides of the jar. Then add corn syrup (for color add food coloring) once again making sure the syrup doesn’t touch the sides of the jar. Next add maple syrup, making sure not to let the syrup touch the sides of the jar. Then add dish soap, then water (for color add food coloring). then add olive oil. Lastly add rubbing alcohol (for more color add food color). Add it slowly, don’t mix it with any of the other layers. Use a dropper or turkey baster.
Learning: liquid density
