Warblettes are co-polymers that can absorb up to 200 times their volume in water. The warblettes water marbles are perfect for science fair experiments, in the classroom, or just as a fun activity for your family. These water marbles are non-toxic and come in clear, red, blue, green, and yellow. Heath Scientific offers a warblettes lab activity book that includes 13 activities that focus on different subjects like math, graphing, and cellular biology, perfect for science fair projects and classroom experiments. The procedures for running each experiment are explained and the labs can be modified to meet your specific needs.

Enough about the details lets take a look at the Warblettes in action!! As mentioned they are able to absorb 200 times their volume in water. Our experiment compares the warblette, aluminum foil from a chewing gum package,  and a piece of paper towel. This will show the differing amounts of absorption between the water marble and these other household items.

First the paper towell, foil, and the warblette were placed in water bottle caps, then each cap was filled with water.  (Note that we are using bottle caps as they are easily accessible in the home.  If you wish to measure liquid absorbtion in milliliters, a beaker or test tube will need to be used).  The items were left alone for 8 hours allowing them to absorb as much water as possible.

The picture below shows all of the items after 8 hours of absorption time. As you can see the aluminum foil absorbed no water, which was expected as metal is a virtually non-absorbent material. The paper towel absorbed a little more than half of the water in the cap. Paper towels are designed to clean up spills so it makes sense that this would be the case. Finally the warblette absorbed all of the water available in the cap, we even filled it a second time and it absorbed this too! The warblettes actually lock the water away so that they are not wet to the touch like the paper towel is.

Here is a picture of the warblette before the introduction of any water, as you can see it is very small in comparison to a dime.

This is the warblette at the end of the experiment; note the drastic size change after the absorption of water.

Warblettes have superior absorbent properties when compared with the aluminum foil and paper towel. This is an example of an easy and fun experiment that can be done with simple household items. The lab activity book offers more challenging experiments that are better suited for science fairs and classroom experiments.

They offer warblettes and many other science supplies, science fair kits, and other fascinating products.

It has been five days now since we planted a sunflower seed covered in our post Growing A Sunflower Seed – Childrens Learning Activity and this morning provided evidince that germination was successful as a couple of small green sprouts could be seen in the potting soil.  We removed the seran wrap from the top of the paper cup, added a few teaspoons of water, and placed our Sunflower sprout in the window sill to garner some spring sunlight.

We will provide another update once our Sunflower is ready to be planted in a bigger container and when it blooms.

The growth stages of a plant can be fascinating for children as they are able to watch a tiny seed turn into a living organism. In some cases the result will display beauty like the sunflower in this activity or the result will be edible like vegetables produced by a tomato plant or corn stalk.  Though a plant learning exercise can require patience, it does provide both parent/teacher and child the routine activity of checking on the plant’s progress on a daily basis.

Materials Required for ‘Growing A Sunflower’

• 3 sunflower seeds
• 1/2 cup of potting soil
• a small paper cup
• 1/3 cup of luke warm water
• saran wrap to cover the cup during germination

The Activity

With all items in the materials list present, the child should be introduced to the seeds.  Then, the child can be shown the following video that will give them a vision of the sunflower learning activity and its outcome.

Once this is complete, the following steps should be followed.

1)  Place potting soil into the paper cup.  Do not pack it as you will want the soil to be loose.

2)  Take a pencil or other narrow object and create three holes in the dirt.

3)  Have the child place a seed in each hole and then cover with a little more soil.

4)  Pour the water into the cup and then cover with saran wrap.

5)  Place the cup on a window sill or classroom cabinet surface.

Sunflower Germination

The seeds will need to go through a germination process over the next week to two weeks.  Water is extremely important during this process.  This is why the cup has been covered with saran wrap in order to keep moister in the cup.  Once the germination process is completed, the saran wrap will need to be removed.  You can do one of two things: the first is to simply remove the saran wrap after the first week; the second is to wait until you see the seed sprouting through the dirt and then remove the wrap.

Sunflower Growth

After germination, place the sunflower in a well-lit area and provide water on a daily basis.  DO NOT over water your sunflower.  Once the sunflower has several inches in height, it should be transplanted to an outside flower pot or garden as your new sunflower will need room, sun, and water to flurish.

This post takes a look at the Hydro-Splitter Kit offered by Heath Scientific. The Hydro-Splitter Kit is a science fair project for kids that educates them about electricity and the electrolysis of water.

Other projects similar to the Hydro-Splitter are also available from the Heath Scientific website. The website offers science supplies as well as other science projects cover a wide range of topics from carbon to light and optics kits. These kits offer a cost effective way for parents to enrich their children’s minds while having fun at the same time.

General Information

Water is made up of twice as many hydrogen molecules as oxygen molecules; this is why the chemical formula is H2O. Electricity breaks this formula down when introduced into water. The molecules split with hydrogen appearing at the cathode and the oxygen will mix with one hydrogen molecule making hydroxide.

Supplies Needed

- 1 Beaker
- 2 Carbon Rod Electrodes
- 1 Acid/Base Indicator
- 3 Alligator Clip Wires
- Salt
- 2 Droppers
- 9 Volt Battery- not included in the Hydro-Splitter Kit

Experiment Procedure

The carbon rod electrodes are connected to the battery with the alligator clip wires. Fill the beaker with 200 milliliters of water along with 25 drops of acid/base indicator and a pinch of salt. Adding a second 9 Volt battery can increase the speed of the reaction.

Results

There will be more hydrogen molecules than oxygen in the water and the electrode that the hydrogen is drawn to will have more bubbles. The water around this electrode will be blue; the water around the other electrode where the oxygen is drawn will be pink. This kit allows for a cost effective way to explain the concepts of electricity and voltage.

Fire-Bellied Toad

The following information is general care information for a fire-bellied toad and is provided by Heath Scientific. Heath Scientific has a full supply of live critters for educational institutions and home school environments. See the Live Critter section of our website.

Temperature – 72-88F

Light Requirements – Indirect sunlight (Classroom lighting)

Feeding – 2-3 crickets, twice a week. For easier care, a larger number of
crickets can be added (1 dozen) with a small piece of potato for nutrition.

Habitat – Semi-aquatic. Use spring or tap water treated with chlorine remover. Add water to a level equal with the top of the gravel. The Toads will often hide under a damp piece of moss.

Handling – Do not handle with dry hands as this may damage their skin.
Do not handle frequently. Wash hands before and after handling.

Care – Change water 1 time per week. Dirty water can allow contaminates

General Information:

Fire bellied toads are members of the genus Bombina. this genus has 4-5 different species. The most common species in the pet industry is Bombina orientalis and is found in NE China and Korea. The dorsal side is light brown to bright emerald green with shiny black spots. The ventral side is marbled red and black. The Bombina species is both diurnal and nocturnal, live in groups and are largely aquatic.They will float on the water with their legs out, soaking up the sun.

In The Wild

Bombina spawns throughout the summer and “rest” from the end of October to March. During this time they will hide under damp leaves for moisture and protection. When frightened, the toad will lay on it’s back, displaying the red belly. These bright colors can frighten away predators. The main predators consist of large aquatic frogs and snakes. When food supply is short or the concentration of animals is too high, cannibalism is a common occurrence. When laying eggs, they will attach them to floating plants or inside hollow spots in rocks.

In Captivity

The fire bellied toad needs a habitat that is well ventilated to prevent fungal infections. Indirect sunlight will assist in hindering fungal growth and provide certain vitamins. Breeding in captivity is more common in  orientalis than other species. Many hiding places, clean water source and proper over-wintering are necessary for breeding success. One interesting fact is that captive bred toads develop a yellow belly instead of the normal red. Experts say that supplemental canthaxanthin can reverse this phenomenon.

Betta (Fighting Fish)

The following information is general care information for a beta fish and is provided by Heath Scientific. Heath Scientific has a full supply of live critters for educational institutions and home school environments. See the Live Critter section of our website.

Temperature – 72-88F

Light Requirements – Indirect Sunlight (Classroom lighting)

Feeding – Prepared tropical fish bites (Betta Bites). 2-3 pellets (or flakes) per day. If the fish is overfed, frequent water changes may be necessary.

Habitat – Slow moving or standing water.

Handling – Never touch a fish with dry hands as this will damage their slime coat. Bettas can jump and require a lid or lower water level.

Care - Use distilled water or tap water with chlorine remover added. Aclimate water to room temperature prior to adding to tank. Change the water when it becomes cloudy.

Volume Density Experiment

The butterflies cycle of life is very different from the rest of nature. The butterfly’s lifecycle has four stages; which include Egg, Larva (caterpillar), Pupa (cocoon), and Adult.  Butterflies are important to nature because they are an agent of pollination.  This means they pollinate flowers, which happens when pollen grains are transferred from the male to the female part of the flower.

Egg

Butterfly eggs consist of a hard outer shell; the outer shell has wax on the inside to prevent it from getting too dry. These eggs are usually affixed to a plant leaf with glue that quickly hardens. The egg stage lasts for a few weeks.

Caterpillar

During the larva stage the caterpillar consumes plant leaves, finding and consuming the plant leaves is how the caterpillar spends most of its time. Many caterpillars have markings on their rear end that look like eyes. This along with ability to produce chemicals that smell or are toxic offers defense from birds and other predators.

Pupa

This is the stage in which the caterpillar searches for a desirable location in which to turn itself from larva into a pupa. The caterpillar will attach itself to a branch or limb and moult for the last time. Metamorphosis takes place and a butterfly emerges at the end of this cycle.

Adult Butterfly

Adult Butterflies are not able to fly until their wings gain blood circulation and completely unfold; this usually takes 1-3 hours depending on the type of butterfly. Without a net or other type of protection they are very vulnerable while waiting for their wings to function.  The adult is known as the imago, as an adult the butterfly gains the ability to reproduce. The adult butterfly has 4 wings and 6 legs.

Learning Activity for Children

Butterflies are fascinating for children because of their beauty and the simple fact that they fly.  Rarely can a book teach a child the stages of a butterfly’s life cycle better than simply experiencing it.  Raising butterflies through their life cycle is a fun educational activity for children.  To successfully raise butterflies through their life cycle, you will need:

• Painted Lady Caterpillars with food.
• Vials and lids
• And a two foot hanging butterfly net

Heath Scientific provides these supplies along with complete instructions in a Live Butterfly Classroom Kit .  Though designed for the classroom, it is a great activity for parents and children of all ages.
