    What a great starter scope! Many of the features you'll find on a more expensive scope are now available for the young scientist. This battery operated (3 AA batteries are not included) microscope has:

    • • rotatable nosepiece with 4X, 10X, and 40X objectives
    • • 10X widefield eyepiece on an inclined head
    • • 6 hole disc diaphragm
    • • real optical glass lenses
    • • 3 ½" x 3 ½" stage with spring mounted stage clips
    • • coarse focus knob
    • • dual LED lights
    • • powder-coated metal construction with sturdy plastic base

    View slides using the light below and solid objects with the upper light. You won't find this feature on any of our other microscopes. See slides up to a 400X magnification and solid objects up to 100X magnification. Look closely and you'll be able to see Abraham Lincoln sitting in his memorial on the back of the penny!

    This microscope comes with a nice accessory set which includes: 5 blank slides, 4 prepared slides, 1 concaved slide, slide labels, 10 cover glasses, pipette, forceps, lens paper, small plastic test tube, small plastic Petri dish, straight teasing needle, and red and blue dye. A 10-page user's manual explains how to prepare slides, operate the microscope, and offers suggestions for observation.

    The LED lights burn longer and cooler than incandescent lighting, so no chance of little fingers getting hot. An automatic stage stop is helpful in keeping the objectives from touching the slides; however, it doesn't work well with the 40X objective. This objective is longer and the stage doesn't stop soon enough before putting pressure on the slide. You'll also notice that there is no 'fine focus' knob. I thought that would be a problem getting things in focus, but really had very little difficulty. I looked at several slides and objects on all of the settings of this microscope. I'm really impressed with the features offered for such a low price. ~ Donna

    A great combination of puzzle solving ability and manual dexterity. 1 to 4 players race to complete each “formula.” Players start with three test tubes, each with a pair of purple, red, or green marbles. The “formula” card shows the desired arrangement of the marbles in the test tubes. “Pour” the marbles back and forth between the test tubes without touching the marbles and be the first to match the pattern. All players compete every round, so the 54 challenge cards are usually completed in about 15 minutes. ~ Bob

    Part of the Nancy B's Science Club series, this set pairs a junior microscope with an activity journal for guided observations. The beginner microscope features 30x-400x magnification, LED lighting, a coarse focus knob and a rubber eyepiece cup. There are actually two lights – one on the bottom and one on top, so you can use it as a light microscope (for semitransparent slides) and a dissecting microscope (for 3-D objects). Although all plastic, the microscope has a sturdy design and is battery-powered, so you can take it out in the field without worry. While you can't compare this one to an actual compound microscope on optics, it seems to work pretty well for an inexpensive scope, especially in the low magnification range. Several tools are also included with the microscope - four prepared slides, seven blank slides, seven cover slips, a Petri dish, specimen vial, spatula, tweezers, scalpel, stirring rod, test tube and pipette. The 22-page activity journal both acquaints students with how to use the microscope and provides ideas for projects and activities that they can complete while also giving them spaces to record observations. Activities include a variety of subjects, including examining cheek cells, the marks made by various writing utensils, ground spices and more. Please note that the microscope is only battery-powered and requires 3 AA batteries, not included.

    For all you Ms. Frizzle fans, here's another Magic School Bus Science Kit. You can let your little ones do chemistry like all the students in Ms. Frizzle's science class. This Chemistry Lab comes packaged in a replica of the Magic School Bus (made of cardboard measuring 15" long by 8 ½" high) with storage space and trays for all the kits components. This kit includes most of the hard-to-find materials needed to do experiments: Petri dish, string, peppercorn, balloon, wooden craft stick, piece of iron, ph chart, 25 ml measuring cup, ph paper, pipette, blue and red litmus paper, pencil, safety goggles, plastic measuring spoon, plastic funnel, 3 plastic test tubes, test tube brush, soap, cardboard, clay, white blue, borax, yeast, chromatography paper, foil, liquid dish soap, straw, and ruler.

    51 glossy cards accompany the kit and will help your young chemist get started learning about scientific tools, measurements, acids and bases, and much more. The first twelve cards offer general information, messages from Ms. Frizzle, safety and instructions for the kit. Cards 13 through 51 are experiments. The front of each card gives a list of materials needed, steps to follow for the experiment, and illustrations. An explanation of the experiment is found on the reverse side of the card. You will get to make sticky ice, test materials for acidity, inflate a balloon without blowing into it, make pepper jump, learn about buoyancy, make a speed boat, and much more as you learn with Ms. Frizzle and her class.

    A data notebook is included for recording data in specific lessons. This is a small 5"x 7" stapled booklet with space to record observations. If you are doing the experiments with multiple students, you can have them work in teams to record the information or let them make their own notebook – this one is pretty simple. Use this kit as a chemistry unit study or alongside your curriculum – either way you will have fun with Ms. Frizzle and the gang! ~ Donna

    The Chemistry 60 Kit will provide hours of experiment fun without harmful chemicals. Topics explored include: chemical reactions, acids and bases, chromatography, crystal growing, surface tension, solutions and colloids, expansion of gases, magnetism, optics, growing plants, and much more. While some activities will require adult supervision, many of them can be done independently. Most items are provided in the kit, but you will need to gather household items to complete some of the activities.

    Each activity is colorfully illustrated with step-by-step instructions, and a very simple explanation for each activity is offered at the end. Students will test for acids by using red cabbage juice, write a magic message using lemon juice, build an erupting volcano, see and hear gas expand, grow salt crystals, and much more.

    Kit contains sodium hydrogen carbonate, iron powder, sand, plastic test tube rack, plastic test tubes, test tube holder, stopper, magnifying glass, green felt tip pen, plastic beaker, 25 milliliter measuring cup with lid, safety goggles, measuring spoon, eye dropper, funnel, tweezers, magnet in holder, washers, paper clip, pH scale, pH paper, thread, mirror, drinking straw, modeling dough, rubber band, Styrofoam, and instruction booklet.

    You may be tempted to bypass this exceptional chemistry kit in light of the unassuming title of "first chemistry set." There is nothing babyish or fluffy about this kit. Rather, this kit introduces rock-solid chemistry to the upper elementary and middle school student. Suffice it to say, these are not childish or overly simplistic experiments. Beginning with making a plaster test tube stand, the twenty-five experiments that follow cover a wide range of concepts. Examples include dissolving salt and sugar solutions, evaporation, making crystals, acid and alkalis, and so much more. Contained within the sturdy cardboard kit are the required lab equipment and an Experiment Manual. I think you will be pleasantly surprised at the vibrant illustrations in this 8 ½" x 11 ½", 48 pg. manual. Not only is it appealing to look at, valuable content includes teaching tips, the ABC's of experimentation, basic rules of safety for the science lab, a master material list and specific experiment lists, step by step instructions for labs, explanations of chemical reactions and other interesting tidbits related to various experiments. Included science tools included: plaster, measuring spoon, 100 and 200 ml. measuring cups, label sheets, plaster mold, rubber stopper, pH step strips, magnifying lens, Petri dish with lid, pipettes, test tubes, filter paper, vial with spoon, funnel, balloon, bendable drinking straw, safety glasses, and wooden spatula. You will need to supply a variety of readily available items (contact us for a full list). Parental Supervision required. ~Deanne
