What do you do with your child over the summer?
Help them explore their natural world with the following science activities that can be done with common household items.
Rainbow Liquids Jar
This teaches children about density of liquids.
Materials: large jar with a lid (thinner is better), at least 2 liquids with clearly distinct densities (good choices include lamp oil, rubbing alcohol, vegetable oil, water, dish/liquid soap, honey), measuring cups, smaller jars, various food coloring colors and mixing sticks (optional)
- Measure out small portions of each liquid you have. The portions should depend on how large your jar is as well as the number of liquids. Be sure to leave enough room at the top to avoid overflow. For example, if your jar holds one liter and you have 5 liquids, separate out about 15mL of each liquid.
- Add food coloring so each liquid is clearly distinct for your child to observe later (optional).
- Add liquids into the jar one by one. Slowly is better so your child can see the liquids moving.
- Show your child that shaking the jar does not change the order of the liquids, nor will it mix them.
Edible Celery Rainbow
This teaches children about water movement up a celery stalk (and through trees).
Materials: several stalks of celery (at least one to march each color of food coloring), water, small jars for water (plastic baggies taped to a window will also work), various food coloring (can be mixed together to make more colors)
- Cut the bottom of the celery to ensure that water can be absorbed quickly through the stalks.
- Add water into each of the small jars or plastic baggies.
- Add an appropriate amount of food coloring to the water. The color should be rich so they are clearly visible when the water is taken up by the celery.
- Put the celery stalks into each jar or baggie.
- Set for 30 minutes, then revisit every 30 minutes until the celery has completely changed colors.
- Revisit to see the colors traveling up the stalk.
