  • taking each jar, add one tablespoon of each item.
  • Ensure each jar is filled with warm water. A good scientist takes meticulous measurements to ensure that all variables, save one, are the same.
  • Finally, give each jar a good stir and wait 60 seconds. For these activities, I appreciate having a kid-friendly timer available.
  • After the timer has expired, your children may identify which components dissolved and which did not. Were they accurate? Was it necessary for them to amend their answers?

How it works

It may appear to be producing a sloppy mess, but you are experimenting with a key topic in chemistry known as solutions. You may or may not have made solutions by combining these solids (solutes) with a liquid (solvent).

You can use two or more chemicals in your experiment, but we’re just using one solute and one solvent. Duringmost cases, the solute is less abundant than the solvent. What would happen if the situation was reversed?

Science experiments for kindergarten

Float or sink

  • On a sheet of paper, write the words “sink” and “float” in two columns.
  • Request that your kindergartener collect various items from around the home. Items such as pins, rubber ties, paper, pencils, spoons, and other items.
  • Note that your child understands the meanings of the phrases “sink” and “float.”
  • gush in water in a pan halfway and ask your child to drop the things in one by one. Observe which ones float and which ones sink and record your findings on paper. It might be one of the most engaging and fun science exercises for kindergarten students.


The heavier things sink, whereas the lighter ones float.

Bottled waves science experiments

  • Fill a bottle two-thirds with castor oil and the remainder with water with your child’s assistance.
  • Close the lid and add some food coloring.
  • Let your child to turn the bottle side to side to see how the water creates waves.


The gravitational attraction of the earth, as it revolves on its axis, causes waves.

Invisible writings science experiments

  • Instruct your child to mix a cup of water with a few drops of dishwashing detergent.
  • Your child can use a cotton swab dipped in the mixture to draw or write on a bathroom mirror.
  • When it’s time for a bath, the message on the mirror will become apparent when the bathroom fogs up. One of the simple science activities for kindergarten that will let kids wonder about science is invisible writing.


Water molecules will not develop on the mirror as a result of the dishwashing detergent, allowing the message to be seen.

Magnet plays science experiments

  • Request that your child pick objects from around the home and place them around a magnet.
  • Show them to which ones are attracted by the magnet and which are not.


Anything made of iron, nickel, or other metals will be pulled by a magnet.

High school science experiments

Ice-Cream Chemistry: Lowering the Freezing Point of Water: Have you ever made ice cream from scratch? If you have, you are undoubtedly aware that the ice cream mixture must be freezing in order to freeze rapidly. Ice cubes alone will not freeze the combination. But if additives like salt or sugar are added to the ice cubes that surround the ice cream container, the liquid will freeze. Why does it function that that? What effect does adding salt or sugar have on water’s freezing point? Find out with this icy scientific activity, and then use your findings to make your tasty ice cream!


  • Ice Cream Making Chemistry Kit (1). 16 millimeters (mm) by 150 millimeters (mm) test tubes (7)
  • Rack for test tubes
  • Beakers with a capacity of 250 mL (6)
  • a graded cylinder with a capacity of 100 mL
  • Gram balance with 0.1-gram accuracy
  • Thermometer with a minimum temperature range of 10°C
  • Stirring rods (2)
  • Styrofoam® cup, large (12 ounces [oz] or more)

You’ll also need the following items:

  • Permanent marker for water ice
  • Table salt (sodium chloride, NaCl) or sea salt (sodium chloride, NaCl) (500 g or 18 oz)
  • Sugar (sucrose) in granules (360 g or 13 oz)
  • Lab notebook with a little spoon or scoop for scooping up salt and sugar


This science project, you’ll examine how dissolving chemicals in water alters a solution’s freezing point. Then, apply your findings to produce delectable ice cream.


Preparing the ice bath

  • Fill the Styrofoam cup 34 full of ice, then sprinkle 14–12 inches of table or sea salt on top.
  • Using a spoon or a stirring rod, stir the ice-salt mixture thoroughly.
  • Check the temperature of the ice-salt combination using the thermometer. It should be around 10 degrees Celsius.
  • This ice bath will be used to freeze different test liquids. You may need to drain melted water from the ice bath and replace the ice and salt during your tests. Before starting your experiment, wait until the temperature of the ice bath has dropped to around 10°C.
  • Ahead of freezing each of your test liquids, check the temperature of the ice bath.
  • Prior to measuring the freezing point of your test liquids, thoroughly cleanse and dry the thermometer. You don’t want salt water to get into your test liquids via the thermometer!

Getting the Freezing Points of Different Test Liquids

  • Three salt solutions, three sucrose (sugar) solutions, and a pure water control will be used to determine the freezing point of seven distinct test liquids. Pure water control is critical for calculating the freezing point of your experiment’s water, which may or may not be exactly 0°C.
  • Label one of the test tubes and one of the 250 mL beakers as “#1” using a permanent marker.
  • Inside beaker labeled #1, make your first test liquid.
  • Weigh 2.9 g of table or sea salt (NaCl) into the beaker using the digital scale.
  • Some scales, such as the one included in the Science Buddies package, feature a cover that protects the weighing surface. Before utilizing the scale, this should be deleted.
  • In a graduated cylinder, measure 100 mL of water and pour it into the beaker with the salt. Stir until all of the crystals have dissolved using a stirring rod.
  • Using water, rinse the stirring rod. You don’t want the other test solutions to be contaminated.

Next steps

  • Pour the test tube #1 with test liquid #1 to one-third capacity. Place the test tube, ice, and salt in the Styrofoam cup.
  • The level of liquid in the test tube should be lower than the ice and salt in the cup.
  • Allow no ice or salt to fall into the test tube from the cup.
  • With a thermometer, carefully stir the test liquid in the test tube while keeping note of the temperature.
  • During the first 5 minutes, examine the test tube often for crystals, then check every minute after that for at least 45 minutes. Figure 1 depicts the appearance of ice crystals. Note that the actual length of time it takes for crystals to develop will vary depending on the circumstances of your test. However, you should observe crystals develop fast in the majority of your experiments. However, test liquid 6 may take a long time to develop crystals.

Steps continuation

  • Record the temperature in your lab notebook when the first ice crystals develop on the interior wall of the test tube. The freezing point of the test liquid is this.
  • Roll the test tube in your palm to melt the ice again, then dump the contents of the test tube down the drain. (Important: Handle the very cold glass test tubes with care, since they are extremely fragile.) They are more prone to breakage when exposed to rapid temperature changes.) Replacing the same test tube with fresh test liquid #1 is the next step. With a new sample, repeat steps 4–7. For test solution #1, you’ll need three replicates, all of which should be done in the same test tube.
  • Simply repeat steps 3 and 4 if you need extra test liquid.
  • Steps 2–8 should be repeated for each of the remaining test liquids, Also making it careful to use a new beaker and test tube for each. You don’t want one test liquid’s residue to contaminate the other test liquids. Verify the beakers are labeled so you know which test liquid is in which.
  • 5.8 g Sodium Chloride in 100 mL water = test liquid #2
  • 11.7 g Sodium Chloride in 100 mL water = test liquid #3
  • 17.1 g sugar in 100 mL water = test liquid #4
  • 34.2 g sugar in 100 mL water = test liquid #5.
  • 68.5 g sucrose in 100 mL water = test liquid #6
  • 100 mL water as a test liquid #7 (simply measure 100 mL of water in the graduated cylinder and store the water in the graduated cylinder)


Handle the glass test tubes with caution. However, they are exposed to extremely cold temperatures or fast temperature. fluctuations occur, they are more likely to break, especially if they are bumped or handled violently.


The advantages are considerable for children of all ages. Science projects aid in the development of a child’s resourcefulness. Specifically their goal-setting, planning, and problem-solving abilities. It also fosters intellectual curiosity by assisting youngsters in learning new methods. To ask questions and comprehend the world.
